Description

FIELD OF THE INVENTION



[0001] The invention relates to new isoindolin-1-one derivatives, to pharmaceutical compositions comprising said compounds and to the use of said compounds in the treatment of diseases, e.g. cancer.

BACKGROUND OF THE INVENTION



[0002] The transformation-related protein 53 (TP53) gene encodes a 53 KDa protein - p53. The tumour suppressor protein p53 reacts to cellular stresses, such as hypoxia, DNA damage and oncogenic activation, via a number of posttranslational modifications including phosphorylation, acetylation and methylation, and acts as a signalling node in the diverse pathways that become activated. p53 has additional roles in other physiological processes, including autophagy, cell adhesion, cell metabolism, fertility, and stem cell aging and development. Phosphorylation of p53, resulting from activation of kinases including ATM, CHK1 and 2, and DNA-PK, results in a stabilised and transcriptionally active form of the protein, thus producing a range of gene products. The responses to p53 activation include apoptosis, survival, cell-cycle arrest, DNA-repair, angiogenesis, invasion and autoregulation. The specific combination of which, in concert with the cell's genetic background, gives rise to the observed cellular effect i.e. apoptosis, cell-cycle arrest or senescence. For tumour cells, the apoptotic pathway may be favoured due to the loss of tumour suppressor proteins and associated cell cycle checkpoint controls, coupled with oncogenic stress.

[0003] Under conditions of stress such as hypoxia and DNA damage it is known that the cellular level of the protein p53 increases. p53 is known to initiate transcription of a number of genes which govern progression through the cell cycle, the initiation of DNA repair and programmed cell death. This provides a mechanism for the tumour suppressor role of p53 evidenced through genetic studies.

[0004] The activity of p53 is negatively and tightly regulated by a binding interaction with the MDM2 protein, the transcription of which is itself directly regulated by p53. p53 is inactivated when its transactivation domain is bound by the MDM2 protein. Once inactivated the functions of p53 are repressed and the p53-MDM2 complex becomes a target for ubiquitinylation.

[0005] In normal cells the balance between active p53 and inactive MDM2-bound p53 is maintained in an autoregulatory negative feedback loop. That is to say that p53 can activate MDM2 expression, which in turn leads to the repression of p53.

[0006] It has been found that inactivation of p53 by mutation is common in around half of all common adult sporadic cancers. Furthermore, in around 10% of tumours, gene amplification and over-expression of MDM2 results in the loss of functional p53, thereby allowing malignant transformation and uncontrolled tumour growth.

[0007] Inactivation of p53 by a range of mechanisms is a frequent causal event in the development and progression of cancer. These include inactivation by mutation, targeting by oncogenic viruses and, in a significant proportion of cases, amplification and/or an elevated rate of transcription of the MDM2 gene resulting in overexpression or increased activation of the MDM2 protein. Gene amplification of MDM2 giving rise to overexpression of MDM2 protein has been observed in tumour samples taken from common sporadic cancers. Overall, around 10% of tumours had MDM2 amplification, with the highest incidence found in hepatocellular carcinoma (44%), lung (15%), sarcomas and osteosarcomas (28%), and Hodgkin disease (67%) (Danovi et al., Mol. Cell. Biol. 2004, 24, 5835-5843, Toledo et al., Nat Rev Cancer 2006, 6, 909-923, Gembarska et al., Nat Med 2012, 18, 1239-1247). Normally, transcriptional activation of MDM2 by activated p53 results in increased MDM2 protein levels, forming a negative feedback loop. The essential nature of p53 regulation by MDM2 and MDMX is demonstrated by gene knockout mouse models. MDM2-/- knockout mice are embryonically lethal around the time of implantation. Lethality is rescued in the double knockout for Mdm2 and Trp53. MDM2 inhibits the activity of p53 directly, by binding to and occluding the p53 transactivation domain, and by promoting the proteosomal destruction of the complex, through its E3-ubiquitin ligase activity. In addition, MDM2 is a transcriptional target of p53, and so the two proteins are linked in an autoregulatory feedback loop, ensuring that p53 activation is transient.

[0008] The induction of the p14ARF protein, the alternate reading frame (ARF) product of the p16INK4a locus, is also a mechanism of negatively regulating the p53-MDM2 interaction. p14ARF directly interacts with MDM2 and leads to up-regulation of p53 transcriptional response. Loss of p14ARF by a homozygous mutation in the CDKN2A (INK4A) gene will lead to elevated levels in MDM2 and, therefore, loss of p53 function and cell cycle control.

[0009] Although MDMX shows strong amino acid sequence and structural homology to MDM2, neither protein can substitute for loss of the other; MDMX null mice die in utero, whereas MDM2 knockout is lethal during early embryogenesis, however both can be rescued by p53 knockout, demonstrating p53-dependence of the lethality. MDMX also binds p53 and inhibits p53-dependent transcription, but unlike MDM2 it is not transcriptionally activated by p53 and so does not form the same autoregulatory loop. Furthermore, MDMX has neither E3 ubiquitin ligase activity nor a nuclear localisation signal, however it is believed to contribute to p53 degradation by forming heterodimers with MDM2 and contributing to MDM2 stabilisation.

[0010] The therapeutic rationale for MDM2-p53 inhibition is that a potent inhibitor of the protein-protein interaction will liberate p53 from the repressive control of MDM2, and activate p53 mediated cell death in the tumour. In tumours, selectivity is envisioned to result from p53 sensing preexisting DNA-damage or oncogenic activation signals that had previously been blocked by the action of MDM2 at normal or overexpressed levels. In normal cells, p53 activation is anticipated to result in activation of non-apoptotic pathways and if anything a protective growth inhibition response. In addition due to the non-genotoxic mechanism of action for MDM2-p53 inhibitors they are suitable for the treatment of cancer in particular in the pediatric population.

[0011] About 50% of cancers harbour cells in which TP53, the gene that encodes for p53, is mutated resulting in a loss of the protein's tumour suppressor function and sometimes even in p53 protein versions that gain novel oncogenic functions.

[0012] Cancers where there is a high level of MDM2 amplification include liposarcoma (88%), soft tissue sarcoma (20%), osteosarcoma (16%) oesophageal cancer (13%), and certain paediatric malignancies including B-cell malignancies.

[0013] WO 2009/156735 (Golding et al) and Hardcastle et al (J. Med. Chem. 2011, 54 (5), 1233-1243) provide a series of isoindoline-1-one derivatives for the inhibition of the MDM2-p53 interaction.

[0014] The present invention describes a novel series of compounds which selectively inhibit the MDM2-p53 interaction and which have anticancer activity.

[0017] In further aspects of the invention there is provided a compound of formula (I) for use in the prophylaxis or treatment of a disease or condition as described herein, pharmaceutical compositions comprising a compound of fomula (I) and processes for the synthesis of a compound of formula (I).

DEFINITIONS



[0018] Unless the context indicates otherwise, references to formula (I) in all sections of this document (including the uses, methods and other aspects of the invention) include references to all other sub-formula, sub-groups, embodiments and examples as defined herein.

[0019] "Potency" is a measure of drug activity expressed in terms of the amount required to produce an effect of given intensity. A highly potent drug evokes a larger response at low concentrations. Potency is proportional to affinity and efficacy. Affinity is the ability of the drug to bind to a receptor. Efficacy is the relationship between receptor occupancy and the ability to initiate a response at the molecular, cellular, tissue or system level.

[0020] The term "antagonist" refers to a type of receptor ligand or drug that blocks or dampens agonist-mediated biological responses. Antagonists have affinity but no agonistic efficacy for their cognate receptors, and binding will disrupt the interaction and inhibit the function of any ligand (e.g. endogenous ligands or substrates, an agonist or inverse agonist) at receptors. The antagonism may arise directly or indirectly, and may be mediated by any mechanism and at any physiological level. As a result, antagonism of ligands may under different circumstances manifest itself in functionally different ways. Antagonists mediate their effects by binding to the active site or to allosteric sites on receptors, or they may interact at unique binding sites not normally involved in the biological regulation of the receptor's activity. Antagonist activity may be reversible or irreversible depending on the longevity of the antagonist-receptor complex, which, in turn, depends on the nature of antagonist receptor binding.

[0021] As used herein, the term "mediated", as used e.g. in conjunction with MDM2/p53 as described herein (and applied for example to various physiological processes, diseases, states, conditions, therapies, treatments or interventions) is intended to operate limitatively so that the various processes, diseases, states, conditions, treatments and interventions to which the term is applied are those in which the protein plays a biological role. In cases where the term is applied to a disease, state or condition, the biological role played by the protein may be direct or indirect and may be necessary and/or sufficient for the manifestation of the symptoms of the disease, state or condition (or its aetiology or progression). Thus, the protein function (and in particular aberrant levels of function, e.g. over- or under-expression) need not necessarily be the proximal cause of the disease, state or condition: rather, it is contemplated that the mediated diseases, states or conditions include those having multifactorial aetiologies and complex progressions in which the protein in question is only partially involved. In cases where the term is applied to treatment, prophylaxis or intervention, the role played by the protein may be direct or indirect and may be necessary and/or sufficient for the operation of the treatment, prophylaxis or outcome of the intervention. Thus, a disease state or condition mediated by a protein includes the development of resistance to any particular cancer drug or treatment.

[0022] The term "treatment" as used herein in the context of treating a condition i.e. state, disorder or disease, pertains generally to treatment and therapy, whether for a human or an animal (e.g. in veterinary applications), in which some desired therapeutic effect is achieved, for example, the inhibition of the progress of the condition, and includes a reduction in the rate of progress, a halt in the rate of progress, amelioration of the condition, diminishment or alleviation of at least one symptom associated or caused by the condition being treated and cure of the condition. For example, treatment can be diminishment of one or several symptoms of a disorder or complete eradication of a disorder.

[0023] The term "prophylaxis" (i.e. use of a compound as prophylactic measure) as used herein in the context of treating a condition i.e. state, disorder or disease, pertains generally to the prophylaxis or prevention, whether for a human or an animal (e.g. in veterinary applications), in which some desired preventative effect is achieved, for example, in preventing occurance of a disease or guarding from a disease. Prophylaxis includes complete and total blocking of all symptoms of a disorder for an indefinite period of time, the mere slowing of the onset of one or several symptoms of the disease, or making the disease less likely to occur.

[0024] References to the prophylaxis or treatment of a disease state or condition such as cancer include within their scope alleviating or reducing the incidence e.g. of cancer.

[0025] The combinations of the invention may produce a therapeutically efficacious effect relative to the therapeutic effect of the individual compounds/agents when administered separately.

[0026] The term 'efficacious' includes advantageous effects such as additivity, synergism, reduced side effects, reduced toxicity, increased time to disease progression, increased time of survival, sensitization or resensitization of one agent to another, or improved response rate. Advantageously, an efficacious effect may allow for lower doses of each or either component to be administered to a patient, thereby decreasing the toxicity of chemotherapy, whilst producing and/or maintaining the same therapeutic effect. A "synergistic" effect in the present context refers to a therapeutic effect produced by the combination which is larger than the sum of the therapeutic effects of the agents of the combination when presented individually. An "additive" effect in the present context refers to a therapeutic effect produced by the combination which is larger than the therapeutic effect of any of the agents of the combination when presented individually. The term "response rate" as used herein refers, in the case of a solid tumour, to the extent of reduction in the size of the tumour at a given time point, for example 12 weeks. Thus, for example, a 50% response rate means a reduction in tumour size of 50%. References herein to a "clinical response" refer to response rates of 50% or greater. A "partial response" is defined herein as being a response rate of less than 50%.

[0027] As used herein, the term "combination", as applied to two or more compounds and/or agents, is intended to define material in which the two or more agents are associated. The terms "combined" and "combining" in this context are to be interpreted accordingly.

[0028] The association of the two or more compounds/agents in a combination may be physical or non-physical. Examples of physically associated combined compounds/agents include:
  • compositions (e.g. unitary formulations) comprising the two or more compounds/agents in admixture (for example within the same unit dose);
  • compositions comprising material in which the two or more compounds/agents are chemically/physicochemically linked (for example by crosslinking, molecular agglomeration or binding to a common vehicle moiety);
  • compositions comprising material in which the two or more compounds/agents are chemically/physicochemically co-packaged (for example, disposed on or within lipid vesicles, particles (e.g. micro- or nanoparticles) or emulsion droplets);
  • pharmaceutical kits, pharmaceutical packs or patient packs in which the two or more compounds/agents are co-packaged or co-presented (e.g. as part of an array of unit doses);


[0029] Examples of non-physically associated combined compounds/agents include:
  • material (e.g. a non-unitary formulation) comprising at least one of the two or more compounds/agents together with instructions for the extemporaneous association of the at least one compound to form a physical association of the two or more compounds/agents;
  • material (e.g. a non-unitary formulation) comprising at least one of the two or more compounds/agents together with instructions for combination therapy with the two or more compounds/agents;
  • material comprising at least one of the two or more compounds/agents together with instructions for administration to a patient population in which the other(s) of the two or more compounds/agents have been (or are being) administered;
  • material comprising at least one of the two or more compounds/agents in an amount or in a form which is specifically adapted for use in combination with the other(s) of the two or more compounds/agents.


[0030] As used herein, the term "combination therapy" is intended to define therapies which comprise the use of a combination of two or more compounds/agents (as defined above). Thus, references to "combination therapy", "combinations" and the use of compounds/agents "in combination" in this application may refer to compounds/agents that are administered as part of the same overall treatment regimen. As such, the posology of each of the two or more compounds/agents may differ: each may be administered at the same time or at different times. It will therefore be appreciated that the compounds/agents of the combination may be administered sequentially (e.g. before or after) or simultaneously, either in the same pharmaceutical formulation (i.e. together), or in different pharmaceutical formulations (i.e. separately). Simultaneously in the same formulation is as a unitary formulation whereas simultaneously in different pharmaceutical formulations is non-unitary. The posologies of each of the two or more compounds/agents in a combination therapy may also differ with respect to the route of administration.

[0031] As used herein, the term "pharmaceutical kit" defines an array of one or more unit doses of a pharmaceutical composition together with dosing means (e.g. measuring device) and/or delivery means (e.g. inhaler or syringe), optionally all contained within common outer packaging. In pharmaceutical kits comprising a combination of two or more compounds/agents, the individual compounds/agents may unitary or non-unitary formulations. The unit dose(s) may be contained within a blister pack. The pharmaceutical kit may optionally further comprise instructions for use.

[0032] As used herein, the term "pharmaceutical pack" defines an array of one or more unit doses of a pharmaceutical composition, optionally contained within common outer packaging. In pharmaceutical packs comprising a combination of two or more compounds/agents, the individual compounds/agents may unitary or non-unitary formulations. The unit dose(s) may be contained within a blister pack. The pharmaceutical pack may optionally further comprise instructions for use.

[0033] The term 'optionally substituted' as used herein refers to a group which may be unsubstituted or substituted by a substituent as herein defined.

Examples of such groups include hydroxymethyl, hydroxyethyl, hydroxypropyl and the like.

[0045] The term 'haloC1-4alkyl' as used herein as a group or part of a group refers to a C1-4alkyl group as defined herein wherein one or more (e.g. 1, 2 or 3) than one hydrogen atom is replaced with a halogen. The term 'haloc1-4alkyl' therefore includes monohaloC1-4alkyl and also polyhaloC1-4alkyl. There may be one, two, three or more hydrogen atoms replaced with a halogen, so the haloC1-4alkyl may have one, two, three or more halogens.

[0047] The term "heterocyclyl group" as used herein shall, unless the context indicates otherwise, include both aromatic and non-aromatic ring systems. Thus, for example, the term "heterocyclyl group" include within their scope aromatic, non-aromatic, unsaturated, partially saturated and saturated heterocyclyl ring systems. In general, unless the context indicates otherwise, such groups may be monocyclic or bicyclic (including fused, spiro and bridged bicyclic groups) and may contain, for example, 3 to 12 ring members, more usually 5 to 10 ring members. Reference to 4 to 7 ring members includes 4, 5, 6 or 7 atoms in the ring and reference to 4 to 6 ring members include 4, 5, or 6 atoms in the ring.

Examples of bicyclic groups are those containing 8, 9, 10, 11 and 12 ring members, and more usually 9 or 10 ring members. The heterocyclyl groups can be heteroaryl groups having from 5 to 12 ring members, more
usually from 5 to 10 ring members. Where reference is made herein to a heterocyclyl group, the heterocyclyl ring can, unless the context indicates otherwise, be optionally substituted i.e. unsubstituted or substituted, by one or more (e.g. 1, 2, 3, or 4 in particular one or two) substituents as defined herein.

[0048] The heterocyclyl group can be, for example, a five membered or six membered monocyclic ring or a bicyclic structure formed from fused five and six membered rings or two fused six membered rings, or two fused five membered rings. Each ring may contain up to five heteroatoms particularly selected from nitrogen, sulfur and oxygen and oxidised forms of nitorgen or sulfur. Particularly the heterocyclyl ring will contain up to 4 heteroatoms, more particularly up to 3 heteroatoms, more usually up to 2, for example a single heteroatom. In one embodiment, the heterocyclyl ring will contain one or two heteroatoms selected from N, O, S and oxidised forms of N or S. In one embodiment, the heterocyclyl ring contains at least one ring nitrogen atom. The nitrogen atoms in the heterocyclyl rings can be basic, as in the case of an imidazole or pyridine, or essentially non-basic as in the case of an indole or pyrrole nitrogen. In general the number of basic nitrogen atoms present in the heterocyclyl group, including any amino group substituents of the ring, will be less than five.

[0049] The heterocyclyl groups can be attached via a carbon atom or a heteroatom (e.g. nitrogen). Equally the heterocyclyl groups can be substituted on a carbon atom or on a heteroatom (e.g. nitrogen).

[0052] The term "heteroaryl" is used herein to denote a heterocyclyl group having aromatic character. The term "heteroaryl" embraces polycyclic (e.g. bicyclic) ring systems wherein one or more rings are non-aromatic, provided that at least one ring is aromatic. In such polycyclic systems, the group may be attached by the aromatic ring, or by a non-aromatic ring.

[0061] A nitrogen-containing heteroaryl ring must contain at least one ring nitrogen atom. The nitrogen-containing heteroaryl ring can be N-linked or C-linked. Each ring may, in addition, contain up to about four other heteroatoms particularly selected from nitrogen, sulfur and oxygen. Particularly the heteroaryl ring will contain up to 3 heteroatoms, for example 1, 2 or 3, more usually up to 2 nitrogens, for example a single nitrogen. The nitrogen atoms in the heteroaryl rings can be basic, as in the case of an imidazole or pyridine, or essentially non-basic as in the case of an indole or pyrrole nitrogen.

[0063] Examples of nitrogen-containing polycyclic heteroaryl groups containing an aromatic ring and a non-aromatic ring include tetrahydroisoquinolinyl, tetrahydroquinolinyl, and indolinyl.

[0064] The term "non-aromatic" embraces, unless the context indicates otherwise, unsaturated ring systems without aromatic character, partially saturated and saturated heterocyclyl ring systems. The terms "unsaturated" and "partially saturated" refer to rings wherein the ring structure(s) contains atoms sharing more than one valence bond i.e. the ring contains at least one multiple bond e.g. a C=C, C≡C or N=C bond. The term "saturated" refers to rings where there are no multiple bonds between ring atoms. Saturated heterocyclyl groups include piperidinyl, morpholinyl, and thiomorpholinyl. Partially saturated heterocyclyl groups include pyrazolinyl, for example pyrazolin-2-yl and pyrazolin-3-yl.

[0065] Examples of non-aromatic heterocyclyl groups are groups having from 3 to 12 ring members, more usually 5 to 10 ring members. Such groups can be monocyclic or bicyclic, for example, have 3 to 7 ring members in particular 4 to 6 ring members. Such groups particularly have from 1 to 5 or 1 to 4 heteroatom ring members (more usually 1, 2, or 3 heteroatom ring members), usually selected from nitrogen, oxygen and sulfur and oxidised forms thereof. The heterocyclyl groups can contain, for example, cyclic ether moieties (e.g. as in tetrahydrofuran and dioxane), cyclic thioether moieties (e.g. as in tetrahydrothiophene and dithiane), cyclic amine moieties (e.g. as in pyrrolidine), cyclic amide moieties (e.g. as in pyrrolidone), cyclic thioamides, cyclic thioesters, cyclic ureas (e.g. as in imidazolidin-2-one) cyclic ester moieties (e.g. as in butyrolactone), cyclic sulfones (e.g. as in sulfolane and sulfolene), cyclic sulfoxides, cyclic sulfonamides and combinations thereof (e.g. thiomorpholine).

[0066] Particular examples include morpholinyl, piperidinyl (e.g. piperidin-1-yl, piperidin-2-yl, piperidin-3-yl and piperidin-4-yl), piperidinonyl, pyrrolidinyl (e.g. pyrrolidin-1-yl, pyrrolidin-2-yl and pyrrolidin-3-yl), pyrrolidonyl, azetidinyl, pyranyl (2H-pyran or 4H-pyran), dihydrothienyl, dihydropyranyl, dihydrofuranyl, dihydrothiazolyl, tetrahydrofuranyl, tetrahydrothienyl, dioxanyl, oxanyl (also known as tetrahydropyranyl) (e.g. oxan-4-yl), imidazolinyl, imidazolidinonyl, oxazolinyl, thiazolinyl, pyrazolin-2-yl, pyrazolidinyl, piperazinonyl, piperazinyl, and N-alkyl piperazines such as N-methyl piperazinyl. In general, typical non-aromatic heterocyclyl groups include saturated groups such as piperidinyl, pyrrolidinyl, azetidinyl, morpholinyl, piperazinyl and N-alkyl piperazines such as N-methyl piperazinyl.

[0067] The terms "oxan" and "oxanyl" as used herein refer to the group:

which may also be referred to as "tetrahydropyran" or tetrahydropyranyl".

[0068] In a nitrogen-containing non-aromatic heterocyclyl ring the ring must contain at least one ring nitrogen atom. The nitrogen-containing heterocyclyl ring can be N-linked or C-linked. The heterocylic groups can contain, for example, cyclic amine moieties (e.g. as in pyrrolidinyl), cyclic amides (such as a pyrrolidinonyl, piperidinonyl or caprolactamyl), cyclic sulfonamides (such as an isothiazolidinyl 1,1-dioxide, [1,2]thiazinanyl 1,1-dioxide or [1,2]thiazepanyl 1,1-dioxide) and combinations thereof.

[0069] Particular examples of nitrogen-containing non-aromatic heterocyclyl groups include aziridinyl, morpholinyl, thiomorpholinyl, piperidinyl (e.g. piperidin-1-yl, piperidin-2yl, piperidin-3-yl and piperidin-4-yl), pyrrolidinyl; (e.g. pyrrolidin-1-yl, pyrrolidin-2-yl and pyrrolidin-3-yl), pyrrolidonyl, dihydrothiazolyl, imidazolinyl, imidazolidinonyl, oxazolinyl, thiazolinyl, 6H-1,2,5-thiadiazinyl, pyrazolin-2-yl, pyrazolin-3-yl, pyrazolidinyl, piperazinyl, and N-alkyl piperazines such as N-methyl piperazinyl.

[0070] The heterocyclyl groups can be polycyclic fused ring systems or bridged ring systems such as the oxa- and aza analogues of bicycloalkanes, tricycloalkanes (e.g. adamantane and oxa-adamantane). For an explanation of the distinction between fused and bridged ring systems, see Advanced Organic Chemistry, by Jerry March, 4th Edition, Wiley Interscience, pages 131-133, 1992.

[0071] Where, in a definition of a cyclic group or ring, it is stated that the cyclic group contains a certain number of heteroatom ring members, e.g. as in the phrase "a 5 or 6 membered ring containing 0, 1 or 2 nitrogen ring members", this is to be taken as meaning that apart from the certain number of heteroatom ring members specified, the remaining ring members are carbon atoms.

[0072] The compound of formula (I) may contain saturated cyclic groups that can be joined to the rest of the molecule by one or more bonds. When the cyclic group is joined to the rest of the molecule by two or more bonds, these bonds (or two of these bonds) can be made to the same atom (usually a carbon atom) of the ring or different atoms of the ring. Where the bonds are made to the same atom of the ring, this results in a cyclic group with a single atom (usually a quaternary carbon) bound to two groups. In other words, when the compound of formula (I) includes a cyclic group that group may either be linked to the rest of the molecule by a bond or the cyclic group and the rest of the molecule can have an atom in common e.g. a spiro compound.

[0073] The heterocyclyl group can each be unsubstituted or substituted by one or more (e.g. 1, 2 or 3) substituent groups. For example, heterocyclyl or carbocyclyl groups can be unsubstituted or substituted by 1, 2, 3 or 4 substituents and particularly it is unsubstituted or has 1, 2 or 3 substituents as defined herein. Where the cyclic group is saturated there may be 2 substituents joined to the same carbon (where the substituents are the same so called geminal or 'gem' disubstitution).

[0074] A combination of substituents is permissible only if such as combination results in a stable or chemically feasible compound (i.e. one that is not substantially altered when kept at 40°C or less for at least a week).

[0075] The various functional groups and substituents making up the compounds of the invention are particularly chosen such that the molecular weight of the compound of the invention does not exceed 1000. More usually, the molecular weight of the compound will be less than 750, for example less than 700, or less than 650, or less than 600, or less than 550. More particularly, the molecular weight is less than 525 and, for example, is 500 or less.

Salts



[0419] Many compounds of the formula (I) can exist in the form of salts, for example acid addition salts or, in certain cases salts of organic and inorganic bases such as carboxylate, sulfonate and phosphate salts. All such salts are within the scope of this invention, and references to compounds of the formula (I) include the salt forms of the compounds.

[0420] The salts of the present invention can be synthesized from the parent compound that contains a basic or acidic moiety by conventional chemical methods such as methods described in Pharmaceutical Salts: Properties, Selection, and Use, P. Heinrich Stahl (Editor), Camille G. Wermuth (Editor), ISBN: 3-90639-026-8, Hardcover, 388 pages, August 2002. Generally, such salts can be prepared by reacting the free acid or base forms of these compounds with the appropriate base or acid in water or in an organic solvent, or in a mixture of the two; generally, nonaqueous media such as ether, ethyl acetate, ethanol, isopropanol, or acetonitrile are used.

[0421] Acid addition salts (mono- or di-salts) may be formed with a wide variety of acids, both inorganic and organic. Examples of acid addition salts include mono- or di-salts formed with an acid selected from acetic, 2,2-dichloroacetic, adipic, alginic, ascorbic (e.g. L-ascorbic), L-aspartic, benzenesulfonic, benzoic, 4-acetamidobenzoic, butanoic, (+) camphoric, camphor-sulfonic, (+)-(1S)-camphor-10-sulfonic, capric, caproic, caprylic, cinnamic, citric, cyclamic, dodecylsulfuric, ethane-1,2-disulfonic, ethanesulfonic, 2-hydroxyethanesulfonic, formic, fumaric, galactaric, gentisic, glucoheptonic, D-gluconic, glucuronic (e.g. D-glucuronic), glutamic (e.g. L-glutamic), α-oxoglutaric, glycolic, hippuric, hydrohalic acids (e.g. hydrobromic, hydrochloric, hydriodic), isethionic, lactic (e.g. (+)-L-lactic, (±)-DL-lactic), lactobionic, maleic, malic, (-)-L-malic, malonic, (±)-DL-mandelic, methanesulfonic, naphthalene-2-sulfonic, naphthalene-1,5-disulfonic, 1-hydroxy-2-naphthoic, nicotinic, nitric, oleic, orotic, oxalic, palmitic, pamoic, phosphoric, propionic, pyruvic, L-pyroglutamic, salicylic, 4-amino-salicylic, sebacic, stearic, succinic, sulfuric, tannic, (+)-L-tartaric, thiocyanic, p-toluenesulfonic, undecylenic and valeric acids, as well as acylated amino acids and cation exchange resins.

[0422] One particular group of salts consists of salts formed from acetic, hydrochloric, hydriodic, phosphoric, nitric, sulfuric, citric, lactic, succinic, maleic, malic, isethionic, fumaric, benzenesulfonic, toluenesulfonic, methanesulfonic (mesylate), ethanesulfonic, naphthalenesulfonic, valeric, acetic, propanoic, butanoic, malonic, glucuronic and lactobionic acids. One particular salt is the hydrochloride salt.

[0423] In one embodiment the compound is the tris(hydroxymethyl)aminomethane (TRIS) salt.

[0424] If the compound is anionic, or has a functional group which may be anionic (e.g., -COOH may be -COO-), then a salt may be formed with an organic or inorganic base, generating a suitable cation. Examples of suitable inorganic cations include, but are not limited to, alkali metal ions such as Li+, Na+ and K+, alkaline earth metal cations such as Ca2+ and Mg2+, and other cations such as Al3+ or Zn+. Examples of suitable organic cations include, but are not limited to, ammonium ion (i.e., NH4+) and substituted ammonium ions (e.g., NH3R+, NH2R2+, NHR3+, NR4+). Examples of some suitable substituted ammonium ions are those derived from: methylamine, ethylamine, diethylamine, propylamine, dicyclohexylamine, triethylamine, butylamine, ethylenediamine, ethanolamine, diethanolamine, piperazine, benzylamine, phenylbenzylamine, choline, meglumine, and tromethamine, as well as amino acids, such as lysine and arginine. An example of a common quaternary ammonium ion is N(CH3)4+.

[0425] Where the compounds of the formula (I) contain an amine function, these may form quaternary ammonium salts, for example by reaction with an alkylating agent according to methods well known to the skilled person. Such quaternary ammonium compounds are within the scope of formula (I).

[0426] The compounds of the invention may exist as mono- or di-salts depending upon the pKa of the acid from which the salt is formed.

[0427] The salt forms of the compounds of the invention are typically pharmaceutically acceptable salts, and examples of pharmaceutically acceptable salts are discussed in Berge et al., 1977, "Pharmaceutically Acceptable Salts," J. Pharm. Sci., Vol. 66, pp. 1-19. However, salts that are not pharmaceutically acceptable may also be prepared as intermediate forms which may then be converted into pharmaceutically acceptable salts. Such non-pharmaceutically acceptable salt forms, which may be useful, for example, in the purification or separation of the compounds of the invention, also form part of the invention.

[0428] In one embodiment of the invention, there is provided a pharmaceutical composition comprising a solution (e.g. an aqueous solution) containing a compound of the formula (I) and sub-groups and examples thereof as described herein in the form of a salt in a concentration of greater than 10 mg/ml, typically greater than 15 mg/ml and typically greater than 20 mg/ml.

N-Oxides



[0429] Compounds of the formula (I) containing an amine function may also form N-oxides. A reference herein to a compound of the formula (I) that contains an amine function also includes the N-oxide.

[0430] Where a compound contains several amine functions one, or more than one, nitrogen atom may be oxidised to form an N-oxide. Particular examples of N-oxides are the N-oxides of a tertiary amine or a nitrogen atom of a nitrogen-containing heterocyclylic group.

[0431] N-Oxides can be formed by treatment of the corresponding amine with an oxidizing agent such as hydrogen peroxide or a per-acid (e.g. a peroxycarboxylic acid), see for example Advanced Organic Chemistry, by Jerry March, 4th Edition, Wiley Interscience, pages. More particularly, N-oxides can be made by the procedure of L. W. Deady (Syn. Comm. 1977, 7, 509-514) in which the amine compound is reacted with m-chloroperoxybenzoic acid (MCPBA), for example, in an inert solvent such as dichloromethane.

[0432] In one embodiment of the invention, the compound is an N-oxide, e.g. from a nitrogen atom on the R6 or R7 group, for example a pyridine N-oxide.

Geometric isomers and tautomers



[0433] Compounds of the formula (I) may exist in a number of different geometric isomeric, and tautomeric forms and references to compounds of the formula (I) include all such forms. For the avoidance of doubt, where a compound can exist in one of several geometric isomeric or tautomeric forms and only one is specifically described or shown, all others are nevertheless embraced by formula (I).

[0434] For example, certain heteroaryl rings can exist in the two tautomeric forms such as A and B shown below. For simplicity, a formula may illustrate one form but the formula is to be taken as embracing both tautomeric forms.



[0435] Other examples of tautomeric forms include, for example, keto-, enol-, and enolate-forms, as in, for example, the following tautomeric pairs: keto/enol (illustrated below), imine/enamine, amide/imino alcohol, amidine/enediamines, nitroso/oxime, thioketone/enethiol, and nitro/aci-nitro.


Stereoisomers



[0436] Unless otherwise mentioned or indicated, the chemical designation of compounds denotes the mixture of all possible stereochemically isomeric forms.

[0437] Stereocentres are illustrated in the usual fashion, using 'hashed' or 'solid' wedged lines. e.g.



[0438] Where a compound is described as a mixture of two diastereoisomers / epimers, the configuration of the stereocentre is not specified and is represented by straight lines.

[0439] Where compounds of the formula (I) contain one or more chiral centres, and can exist in the form of two or more optical isomers, references to compounds of the formula (I) include all optical isomeric forms thereof (e.g. enantiomers, epimers and diastereoisomers), either as individual optical isomers, or mixtures (e.g. racemic or scalemic mixtures) or two or more optical isomers, unless the context requires otherwise.

[0440] The optical isomers may be characterised and identified by their optical activity (i.e. as + and - isomers, or d and l isomers) or they may be characterised in terms of their absolute stereochemistry using the "R and S" nomenclature developed by Cahn, Ingold and Prelog, see Advanced Organic Chemistry by Jerry March, 4th Edition, John Wiley & Sons, New York, 1992, pages 109-114, and see also Cahn, Ingold & Prelog, Angew. Chem. Int. Ed. Engl., 1966, 5, 385-415.

[0441] Optical isomers can be separated by a number of techniques including chiral chromatography (chromatography on a chiral support) and such techniques are well known to the person skilled in the art.

[0442] As an alternative to chiral chromatography, optical isomers can be separated by forming diastereoisomeric salts with chiral acids such as (+)-tartaric acid, (-)-pyroglutamic acid, (-)-di-toluoyl-L-tartaric acid, (+)-mandelic acid, (-)-malic acid, and (-)-camphorsulfonic acid, separating the diastereoisomers by preferential crystallisation, and then dissociating the salts to give the individual enantiomer of the free base.

[0443] Additionally enantiomeric separation can be achieved by covalently linking a enantiomerically pure chiral auxiliary onto the compound and then performing diastereisomer separation using conventional methods such as chromatography. This is then followed by cleavage of the aforementioned covalent linkage to generate the appropriate enantiomerically pure product.

[0444] Where compounds of the formula (I) exist as two or more optical isomeric forms, one enantiomer in a pair of enantiomers may exhibit advantages over the other enantiomer, for example, in terms of biological activity. Thus, in certain circumstances, it may be desirable to use as a therapeutic agent only one of a pair of enantiomers, or only one of a plurality of diastereoisomers.

[0445] Accordingly, the invention provides compositions containing a compound of the formula (I) having one or more chiral centres, wherein at least 55% (e.g. at least 60%, 65%, 70%, 75%, 80%, 85%, 90% or 95%) of the compound of the formula (I) is present as a single optical isomer (e.g. enantiomer or diastereoisomer). In one general embodiment, 99% or more (e.g. substantially all) of the total amount of the compound of the formula (I) may be present as a single optical isomer (e.g. enantiomer or diastereoisomer).

[0446] Compounds encompassing double bonds can have an E (entgegen) or Z (zusammen) stereochemistry at said double bond. Substituents on bivalent cyclic or (partially) saturated radicals may have either the cis- or trans-configuration. The terms cis and trans when used herein are in accordance with Chemical Abstracts nomenclature (J. Org. Chem. 1970, 35 (9), 2849-2867), and refer to the position of the substituents on a ring moiety.

[0447] Of special interest are those compounds of formula (I) which are stereochemically pure. When a compound of formula (I) is for instance specified as R, this means that the compound is substantially free of the S isomer. If a compound of formula (I) is for instance specified as E, this means that the compound is substantially free of the Z isomer. The terms cis, trans, R, S, E and Z are well known to a person skilled in the art.

Isotopic variations



[0448] The present invention includes all pharmaceutically acceptable isotopically-labeled compounds of the invention, i.e. compounds of formula (I), wherein one or more atoms are replaced by atoms having the same atomic number, but an atomic mass or mass number different from the atomic mass or mass number usually found in nature.

[0449] Examples of isotopes suitable for inclusion in the compounds of the invention comprise isotopes of hydrogen, such as 2H (D) and 3H (T), carbon, such as 11C, 13C and 14C, chlorine, such as 36Cl, fluorine, such as 18F, iodine, such as 123I, 125I and 131I, nitrogen, such as 13N and 15N, oxygen, such as 15O, 17O and 18O, phosphorus, such as 32P, and sulfur, such as 35S.

[0450] Certain isotopically-labelled compounds of formula (I), for example, those incorporating a radioactive isotope, are useful in drug and/or substrate tissue distribution studies. The compounds of formula (I) can also have valuable diagnostic properties in that they can be used for detecting or identifying the formation of a complex between a labelled compound and other molecules, peptides, proteins, enzymes or receptors. The detecting or identifying methods can use compounds that are labelled with labelling agents such as radioisotopes, enzymes, fluorescent substances, luminous substances (for example, luminol, luminol derivatives, luciferin, aequorin and luciferase), etc. The radioactive isotopes tritium, i.e. 3H (T), and carbon-14, i.e. 14C, are particularly useful for this purpose in view of their ease of incorporation and ready means of detection.

[0451] Substitution with heavier isotopes such as deuterium, i.e. 2H (D), may afford certain therapeutic advantages resulting from greater metabolic stability, for example, increased in vivo half-life or reduced dosage requirements, and hence may be used in some circumstances.

[0452] In particular, every reference to hydrogen in the application should be construted to cover 1H and 2H, whether hydrogen is defined explicitly, or hydrogen is present implicitly to satisfy the relevant atom's (in particular carbon's) valency.

[0453] Substitution with positron emitting isotopes, such as 11C, 18F, 15O and 13N, can be useful in Positron Emission Topography (PET) studies for examining target occupancy.

[0454] Isotopically-labeled compounds of formula (I) can generally be prepared by conventional techniques known to those skilled in the art or by processes analogous to those described in the accompanying Examples and Preparations using an appropriate isotopically-labeled reagents in place of the non-labeled reagent previously employed.

Esters



[0455] Esters such as carboxylic acid esters, acyloxy esters and phosphate esters of the compounds of formula (I) bearing a carboxylic acid group or a hydroxyl group are also embraced by Formula (I). Examples of esters are compounds containing the group -C(=O)OR, wherein R is an ester substituent, for example, a C1-7 alkyl group, a C3-12 heterocyclyl group, or a C5-12 aryl group, typically a C1-6 alkyl group. Particular examples of ester groups include, but are not limited to, -C(=O)OCH3, -C(=O)OCH2CH3, -C(=O)OC(CH3)3, and -C(=O)OPh. Examples of acyloxy (reverse ester) groups are represented by -OC(=O)R, wherein R is an acyloxy substituent, for example, a C1-6 alkyl group, a C3-12 heterocyclyl group, or a C5-12 aryl group, typically a C1-6 alkyl group. Particular examples of acyloxy groups include, but are not limited to, -OC(=O)CH3 (acetoxy), -OC(=O)CH2CH3, -OC(=O)C(CH3)3, -OC(=O)Ph, and -OC(=O)CH2Ph. Examples of phosphate esters are those derived from phosphoric acid.

[0456] In one embodiment of the invention, formula (I) includes within its scope esters of compounds of the formula (I) bearing a carboxylic acid group or a hydroxyl group. In another embodiment of the invention, formula (I) does not include within its scope esters of compounds of the formula (I) bearing a carboxylic acid group or a hydroxyl group.

Solvates and Crystalline forms



[0457] Also encompassed by formula (I) are any polymorphic forms of the compounds, and solvates such as hydrates, alcoholates and the like.

[0458] The compounds of the invention may form solvates, for example with water (i.e., hydrates) or common organic solvents. As used herein, the term "solvate" means a physical association of the compounds of the present invention with one or more solvent molecules. This physical association involves varying degrees of ionic and covalent bonding, including hydrogen bonding. In certain instances the solvate will be capable of isolation, for example when one or more solvent molecules are incorporated in the crystal lattice of the crystalline solid. The term "solvate" is intended to encompass both solution-phase and isolatable solvates. Non-limiting examples of suitable solvates include compounds of the invention in combination with water, isopropanol, ethanol, methanol, DMSO, ethyl acetate, acetic acid or ethanolamine and the like. The compounds of the invention may exert their biological effects whilst they are in solution.

[0459] Solvates are well known in pharmaceutical chemistry. They can be important to the processes for the preparation of a substance (e.g. in relation to their purification, the storage of the substance (e.g. its stability) and the ease of handling of the substance and are often formed as part of the isolation or purification stages of a chemical synthesis. A person skilled in the art can determine by means of standard and long used techniques whether a hydrate or other solvate has formed by the isolation conditions or purification conditions used to prepare a given compound. Examples of such techniques include thermogravimetric analysis (TGA), differential scanning calorimetry (DSC), X-ray crystallography (e.g. single crystal X-ray crystallography or X-ray powder diffraction) and Solid State NMR (SS-NMR, also known as Magic Angle Spinning NMR or MAS-NMR). Such techniques are as much a part of the standard analytical toolkit of the skilled chemist as NMR, IR, HPLC and MS.

[0460] Alternatively the skilled person can deliberately form a solvate using crystallisation conditions that include an amount of the solvent required for the particular solvate. Thereafter the standard methods described herein, can be used to establish whether solvates had formed.

[0461] Furthermore, the compounds of the present invention may have one or more polymorph or amorphous crystalline forms and as such are intended to be included in the scope of the invention.

Complexes



[0462] Formula (I) also includes within its scope complexes (e.g. inclusion complexes or clathrates with compounds such as cyclodextrins, or complexes with metals) of the compounds. Inclusion complexes, clathrates and metal complexes can be formed by means of methods well known to the skilled person.

Prodrugs



[0463] It is possible to produce pro-drugs of compounds of the formula (I). By "prodrugs" is meant for example any compound that is converted in vivo into a biologically active compound of the formula (I).

[0464] For example, some prodrugs are esters of the active compound (e.g., a physiologically acceptable metabolically labile ester). During metabolism, the ester group (-C(=O)OR) is cleaved to yield the active drug. Such esters may be formed by esterification, for example, of any of the carboxylic acid groups (-C(=O)OH) in the parent compound, with, where appropriate, prior protection of any other reactive groups present in the parent compound, followed by deprotection if required.

[0465] Examples of such metabolically labile esters include those of the formula -C(=O)OR wherein R is:

C1-7alkyl (e.g., -Me, -Et, -nPr, -iPr, -nBu, -sBu, -iBu, -tBu);

C1-7aminoalkyl (e.g., aminoethyl; 2-(N,N-diethylamino)ethyl; 2-(4-morpholino)ethyl); and acyloxy-C1-7alkyl (e.g., acyloxymethyl; acyloxyethyl; pivaloyloxymethyl; acetoxymethyl; 1-acetoxyethyl; 1-(1-methoxy-1-methyl)ethyl-carbonxyloxyethyl; 1-(benzoyloxy)ethyl; isopropoxy-carbonyloxymethyl; 1-isopropoxy-carbonyloxyethyl; cyclohexyl-carbonyloxymethyl; 1-cyclohexyl-carbonyloxyethyl; cyclohexyloxy-carbonyloxymethyl; 1-cyclohexyloxy-carbonyloxyethyl; (4-oxanyloxy) carbonyloxymethyl; 1-(4-oxanyloxy)carbonyloxyethyl; (4-oxanyl)carbonyloxymethyl; and 1-(4-tetrahydropyranyl)carbonyloxyethyl).



[0466] Also, some prodrugs are activated enzymatically to yield the active compound, or a compound which, upon further chemical reaction, yields the active compound (for example, as in antigen-directed enzyme pro-drug therapy (ADEPT), gene-directed enzyme pro-drug therapy (GDEPT), and ligand-directed enzyme pro-drug therapy (LIDEPT), etc.). For example, the prodrug may be a sugar derivative or other glycoside conjugate, or may be an amino acid ester derivative.

METHODS FOR THE PREPARATION OF COMPOUNDS OF FORMULA (I)



[0467] In this section, as in all other sections of this application unless the context indicates otherwise, references to formula (I) also include all other subformula (e.g. formulae I(c), I(f), I(g), I(g'), I(h), I(i), I(j), I(k), I(L), I(m), I(m'), I(n), I(o), I(o'), I(o"), I(p), I(p'), I(q), I(q'), I(q"), I(q‴), I(qʺʺ), I(r), I(s), I(t), I(u), I(v), I(v'), I(w), I(x), I(x'), I(y), (II), (IIa), (IIb), (IIIa), (IIIb), (IVa), (IVb), (V), (VI), (Via), (VII), (VIIa), (Vllb), (VIIc), (Vlld), (VIId'), (VIIe), (VIIe'), (a), (b), (ba), (bb), (bc) or (c)) and examples thereof as defined herein, unless the context indicates otherwise.

[0468] Compounds of the formula (I) can be prepared in accordance with synthetic methods well known to the skilled person.

[0469] According to a further aspect of the invention there is provided a process for preparing a compound of formula (I), or a tautomer, stereoisomer, N-oxide, pharmaceutically acceptable salt, or solvate thereof which comprises:
According to a further aspect of the invention there is provided a process for preparing a compound of formula (I) as hereinbefore defined which comprises:
  1. (a) reacting a compound of formula (XV) with an organometallic reagent of the fomula R7M (where M is a metal) , for example a Grignard reagent of the formula R7MgBr :

    wherein R1, R2, R3, R4, R5, R6, a, s m and n are as defined herein;
  2. (b) interconversion of a compound of formula (I) or protected derivative thereof to a further compound of formula (I) or protected derivative thereof; and/or
  3. (c) deprotection of a protected derivative of a compound of formula (I); and/or
  4. (d) providing a compound of formula (I) and forming a pharmaceutically acceptable salt of the compound.


[0470] The required intermediates are either commercially available, known in the literature, prepared by methods analogous to those in the literature or prepared by methods analogous to those described in the example experimental procedures below. Other compounds may be prepared by functional group interconversion of the groups using methods well known in the art.

[0471] The general synthetic route for the preparation of compounds of formula XV, a key intermediate is set out in the Schemes below.





[0472] Example reagents and conditions for Scheme 1: a) NaOH, H2O, CHCl3, 85 °C; A) AcOH, rt; B) Pb(OAc)4, THF, 0°C; C) NaClO2, H2NSO3H, CH3CN, H2O, rt; D) i) SOCl2, DMF, THF, ii) amine, i-Pr2EtN, THF; E) i) SOCl2, DMF, THF, ii) R3(CH2)S-OH, K2CO3, THF; F) InBr3, R3(CH2)S-OH, DCE, 85 °C; separation and isolation of the 3(R) enantiomer can be achieved at this stage by chiral HPLC.

[0473] In Scheme 1, R1, R2, R3, R4 and R5 are as described herein and W represents a leaving group, such as for example halo, e.g. bromo, or a carbonyl group, such as for example acetyl.

[0474] N-aroylhydrazone (XI) can be prepared by condensing benzaldehyde (IX) with benzhydrazide (X). Reaction with Pb(OAc)4 yields aldehyde (XII), from which a Pinnick oxidation provides acid (XIII). The appropriate benzylamine can then be used to provide 3-hydroxyisoindolinone (XIV), and the R3 - containing side chain added using thionyl chloride or InBr3 and the appropriate alcohol.

[0475] Intermediates of formula (XV) can be used as a starting point for the synthesis of compounds of the present invention having varying functionality in the R3, R6 and R7 positions of Formula I.

[0476] Scheme 2 below sets out example procedures for introducing various R6 moieties starting from intermediates of formula (XVI) (which is the compound of formula (XV) wherein W is Br).



[0477] Example reagents and conditions for Scheme 2: G) (i) toluene, 1,4-dioxane, LiCI, tributyl(1-ethoxyvinyl)tin, Pd(PPh3)4, (ii) HCI, H2O/THF. H) MeMgCl, in the presence of ZnCl2 and/or LaCl3-2LiCl, THF. Separation and isolation of the 3(R) enantiomer can be achieved at any stage by chiral HPLC.

[0478] Bromide (XVI) can be converted to methyl ketone (XVII) for example using 1,4-dioxane, LiCI, tributyl(1-ethoxyvinyl)tin, Pd(PPh3)4, and further converted to the alcohol XVIII by reaction with a methyl Grignard reagent.

[0479] Compounds wherein R6 and R7 are hydrogen, can also be prepared according to the general synthetic Scheme 3. Where R3 contains a hydroxyl group, this can be protected during the synthesis by using standard protecting groups (e.g. TBDMS, TBDPS). Deprotection can be performed using standard conditions (e.g. TBAF).



[0480] Example reagents and conditions for Scheme 3: I) HCOOLi.H2O, Ac2O, Et3N, 4,5-Bis(diphenylphosphino)-9,9-dimethylxanthene, Pd(OAc)2, DMF; J) LiBH4, THF.

[0481] Compounds of formula (XVIII), first shown in Scheme 2, wherein R6 and R7 are methyl, can also be prepared according to the general synthetic Scheme 4.

[0482] In Scheme 4, an intermediate of formula (XXIV) is prepared from an intermediate of formula (XXIII) according to procedure F (InBr3 with R3(CH2)s-OH),. The intermediate of formula (XXIV) is then converted to the compound of formula (XVIII) by a Grignard reaction.



[0483] Example reagents and conditions: F) InBr3 R3(CH2)S-OH, DCE, 85 °C; H) MeMgCl, ZnCl2, THF, 0 °C. Separation and isolation of the 3(R) enantiomer can be achieved at stage F or H by chiral HPLC.

[0484] Compounds of general formula XXX can also be prepared according to Schemes 5 and 6.



[0485] Example reagents and conditions: L) nBuLi, Het-CHO, THF, -78°C ; M) MnO2, MeCN, or I2, Kl, K2CO3; D) i) SOCl2, DMF, THF, ii) amine, i-Pr2EtN, THF or HATU, amine, DIPEA, DMF; E) i) SOCl2, DMF, THF, ii) R3(CH2)S-OH, K2CO3, THF; F) InBr3, R3(CH2)S-OH, DCE, 85 °C; N) R7MgX in the presence of ZnCl2 and/or LaCl3-2LiCl, THF or Al(R7)3, THF or EtLi, ZnEt2, THF. Separation of enantiomers and/or diastereoisomers at Stages E, F and N can be achieved by either chiral and/or achiral HPLC.

[0486] Intermediate XIII (where W is Br) is reacted with nBuLi and an appropriate aldehyde to provide alcohol XXVI which is oxidised to the corresponding ketone (XXVII) either using MnO2 or I2/Kl. Intermediate XXVII is then converted into the 3-hydroxyisoindolinone XXIX following procedures D and E (of F) described above.

[0487] Intermediates of formula XXIX can be used as a starting point for the synthesis of compounds of the present invention having varying functionality in the R7 position of Formula I

[0488] Alternatively the R7 substituents are introduced earlier in the synthesis as showen in Scheme 6. Intermediates of formula XXVII can react with organometallic reagents to provide tertiary alcohol (XXXI) which is then converted to final compounds of Formula I following procedures D and E (or F) (Scheme 6).



[0489] Example reagents and conditions: N) R7MgX in the presence of ZnCl2 and/or LaCl3-2LiCl, THF or Al(R7)3, THF or EtLi, ZnEt2, THF; D) i) SOCl2, DMF, THF, ii) amine, i-Pr2EtN, THF or HATU, amine, DIPEA, DMF; E) i) SOCl2, DMF, THF, ii) R3(CH2)S-OH, K2CO3, THF; F) InBr3 R3(CH2)S-OH, DCE, 85 °C. Separation of enantiomers and/or diastereoisomers at Stages N and E/F can be achieved by either chiral and/or achiral HPLC.

[0490] Compounds of formula XVI (first shown in Scheme 2) can also be used to make compounds of formula XXIX using methods outlined in Scheme 7. In this case, XVI can be converted into a suitable boronate using, for example, Miyaura conditions. The boronate is then treated with an appropriate heterocyclic iodide (or heterocyclic bromide) in the presence of carbon monoxide, a suitable catalyst (such as Pd(dppf)Cl2.) and a solvent (such as toluene or ansole).

[0491] Alternatively, compounds of formula XVI can be treated with an appropriate heterocyclic stannane in the presence of carbon monoxide, a suitable catalyst [such as Pd(dppf)Cl2] and a solvent (such as DMF) to give compounds of formula XXIX (Scheme 7). Separation and isolation of the 3(R) intermediate can be achieved at any stage using chiral HPLC. Compounds of formula XXIX can then be progressed to compounds of formula XXX (as shown in Scheme 5),



[0492] Compounds of formula XVI can also be used to make compounds of formula XXIX using methods outlined in Scheme 8. In this case, compounds of formula XVI can be used to make a Weinreb amide derivative using N,O-dimethylhydroxylamine hydrochloride in the presence of carbon monoxide and a suitable palladium catalyst (e.g. Xantphos G3 catalyst) . The Weinreb amide can then be reacted with an appropriate metallated heterocycle (e.g. the product of 4-bromo-1-methyl-1H-pyrazole and nBuLi in THF) to give compounds of formula XXIX (Scheme 8). Separation and isolation of the 3(R) intermediate can be achieved at any stage using chiral HPLC. Compounds of formula XXIX can then be progressed to compounds of formula XXX (as shown in Scheme 5).



[0493] It will be appreciated that certain compounds can exist in different diastereomeric and/or enantiomeric forms and that processes for their preparation may make use of enantiomerically pure synthetic precursors.

[0494] Alternatively racemic precursors may be used and the mixtures of diastereoisomers generated in these process may be separated by methods well known to the person skilled in the art, for example using non-chiral or chiral preparative chromatography or resolution using diastereomeric derivatives: for example crystallisation of a salt formed with an enantiomerically pure acid such as L-tartaric acid (or enantiomerically pure base such as (1R)-1-phenylethan-1-amine); or enantiomer separation of a diastereomeric derivative formed by covalently linking a enantiomerically pure chiral auxiliary onto the compound, followed by separation using conventional methods such as chiral or non-chiral chromatography. The aforementioned covalent linkage is then cleaved to generate the appropriate enantiomerically pure product.

[0495] A wide range of well known functional group interconversions are known by a person skilled in the art for converting a precursor compound to a compound of formula I and are described in Advanced Organic Chemistry by Jerry March, 4th Edition, John Wiley & Sons, 1992. For example possible metal catalysed functionalisations such as using organo-tin reagents (the Stille reaction), Grignard reagents and reactions with nitrogen nucleophiles are described in 'Palladium Reagents and Catalysts' [Jiro Tsuji, Wiley, ISBN 0-470-85032-9] and Handbook of OrganoPalladium Chemistry for Organic Synthesis [Volume 1, Edited by Ei-ichi Negishi, Wiley, ISBN 0-471-31506-0].

[0496] If appropriate, the reactions previously described below are followed or preceded by one or more reactions known to the skilled of the art and are performed in an appropriate order to achieve the requisite substitutions defined above to afford other compounds of formula (I). Non-limiting examples of such reactions whose conditions can be found in the literature include:

protection of reactive functions,

deprotection of reactive functions,

halogenation,

dehalogenation,

[0497] It will be appreciated that certain compounds e.g. compounds of formulae (I), I(c), I(f), I(g), I(g'), I(h), I(i), I(j), I(k), I(L), I(m), I(m'), I(n), I(o), I(o'), I(o"), I(p), I(p'), I(q), I(q'), I(q"), I(q‴), I(q""), I(r), I(s), I(t), I(u), I(v), I(v'), I(w), I(x), I(x'), I(y), (II), (IIa), (IIb), (IIIa), (IIIb), (IVa), (IVb), (V), (VI), (Via), (VII), (VIIa), (VIIb), (VIIc), (VIId), (VIId'), (VIIe), (VIIe'), (a), (b), (ba), (bb), (bc) or (c) can exist in different diastereomeric and/or enantiomeric forms and that processes for their preparation may make use of enantiomerically pure synthetic precursors.

[0498] Alternatively racemic precursors may be used and the mixtures of diastereoisomers generated in these process may be separated by methods well known to the person skilled in the art, for example using non-chiral or chiral preparative chromatography or resolution using diastereomeric derivatives: for example crystallisation of a salt formed with an enantiomerically pure acid such as L-tartaric acid; or enantiomer separation of a diastereomeric derivative formed by covalently linking a enantiomerically pure chiral auxiliary onto the compound, followed by separation using conventional methods such as chiral chromatography. The aforementioned covalent linkage is then cleaved to generate the appropriate enantiomerically pure product.

[0499] Certain of the required intermediates, are either commercially available, known in the literature, prepared by methods analogous to those in the literature or prepared by methods analogous to those described in the example experimental procedures below. Other compounds may be prepared by functional group interconversion using methods well known in the art.

[0500] In a further embodiment the invention provides a novel intermediate. In one embodiment the invention provides a novel intermediate of (VII), (VIII), (IX), (X), (XI), (XII), (XIII), (XIV), (XV), (XVI), (XVII), (XIX), (XX), (XXI), (XXIII) and (XXIV).

Protecting Groups



[0501] In many of the reactions described herein, it may be necessary to protect one or more groups to prevent reaction from taking place at an undesirable location on the molecule. Examples of protecting groups, and methods of protecting and deprotecting functional groups, can be found in Protective Groups in Organic Synthesis (T. Green and P. Wuts; 3rd Edition; John Wiley and Sons, 1999).

[0502] In particular the compound may be synthesised in protected forms and the protecting groups removed to generate a compound of formula (I).

[0503] A hydroxy group may be protected, for example, as an ether (-OR) or an ester (-OC(=O)R), for example, as: a t-butyl ether; a tetrahydropyranyl (THP) ether; a benzyl, benzhydryl (diphenylmethyl), or trityl (triphenylmethyl) ether; a trimethylsilyl or t-butyldimethylsilyl ether; or an acetyl ester (-OC(=O)CH3).

[0504] An aldehyde or ketone group may be protected, for example, as an acetal (R-CH(OR)2) or ketal (R2C(OR)2), respectively, in which the carbonyl group (>C=O) is treated with, for example, a primary alcohol. The aldehyde or ketone group is readily regenerated by hydrolysis using a large excess of water in the presence of acid.

[0505] An amine group may be protected, for example, as an amide (-NRCO-R) or a carbamate (-NRCO-OR), for example, as: a methyl amide (-NHCO-CH3); a benzyl carbamate (-NHCO-OCH2C6H5, -NH-Cbz or NH-Z); as a t-butyl carbamate (-NHCO-OC(CH3)3, -NH-Boc); a 2-biphenyl-2-propyl carbamate (-NHCO-OC(CH3)2C6H4C6H5, -NH-Bpoc), as a 9-fluorenylmethyl carbamate (-NH-Fmoc), as a 6-nitroveratryl carbamate (-NH-Nvoc), as a 2-trimethylsilylethyl carbamate (-NH-Teoc), as a 2,2,2-trichloroethyl carbamate (-NH-Troc), as an allyl carbamate (-NH-Alloc), or as a 2(-phenylsulfonyl)ethyl carbamate (-NH-Psec).

[0506] Other protecting groups for amines, such as cyclic amines and heterocyclic N-H groups, include toluenesulfonyl (tosyl) and methanesulfonyl (mesyl) groups, benzyl groups such as a para-methoxybenzyl (PMB) group and tetrahydropyranyl (THP) groups.

[0507] A carboxylic acid group may be protected as an ester for example, as: an C1-7 alkyl ester (e.g., a methyl ester; a t-butyl ester); a C1-7 haloalkyl ester (e.g., a C1-7 trihaloalkyl ester); a triC1-7 alkylsilyl-C1-7alkyl ester; or a C5-20 aryl-C1-7 alkyl ester (e.g., a benzyl ester; a nitrobenzyl ester; para-methoxybenzyl ester. A thiol group may be protected, for example, as a thioether (-SR), for example, as: a benzyl thioether; an acetamidomethyl ether (-S-CH2NHC(=O)CH3).

Isolation and purification of the compounds of the invention



[0508] The compounds of the invention can be isolated and purified according to standard techniques well known to the person skilled in the art and examples of such methods include chromatographic techniques such as column chromatography (e.g. flash chromatography) and HPLC. One technique of particular usefulness in purifying the compounds is preparative liquid chromatography using mass spectrometry as a means of detecting the purified compounds emerging from the chromatography column.

[0509] Preparative LC-MS is a standard and effective method used for the purification of small organic molecules such as the compounds described herein. The methods for the liquid chromatography (LC) and mass spectrometry (MS) can be varied to provide better separation of the crude materials and improved detection of the samples by MS. Optimisation of the preparative gradient LC method will involve varying columns, volatile eluents and modifiers, and gradients. Methods are well known in the art for optimising preparative LC-MS methods and then using them to purify compounds. Such methods are described in Rosentreter U, Huber U.; Optimal fraction collecting in preparative LC/MS; J Comb Chem.; 2004; 6(2), 159-64 and Leister W, Strauss K, Wisnoski D, Zhao Z, Lindsley C., Development of a custom high-throughput preparative liquid chromatography/mass spectrometer platform for the preparative purification and analytical analysis of compound libraries; J Comb Chem.; 2003; 5(3); 322-9.An example of such a system for purifying compounds via preparative LC-MS is described below in the Examples section of this application (under the heading "Mass Directed Purification LC-MS System").

[0510] Methods of recrystallisation of compounds of formula (I) and salt thereof can be carried out by methods well known to the skilled person - see for example (P. Heinrich Stahl (Editor), Camille G. Wermuth (Editor), ISBN: 3-90639-026-8, Handbook of Pharmaceutical Salts: Properties, Selection, and Use, Chapter 8, Publisher Wiley-VCH). Products obtained from an organic reaction are seldom pure when isolated directly from the reaction mixture. If the compound (or a salt thereof) is solid, it may be purified and/or crystallized by recrystallisation from a suitable solvent. A good recrystallisation solvent should dissolve a moderate quantity of the substance to be purified at elevated temperatures but only a small quantity of the substance at lower temperature. It should dissolve impurities readily at low temperatures or not at all. Finally, the solvent should be readily removed from the purified product. This usually means that it has a relatively low boiling point and a person skilled in the art will know recrystallising solvents for a particular substance, or if that information is not available, test several solvents. To get a good yield of purified material, the minimum amount of hot solvent to dissolve all the impure material is used. In practice, 3-5% more solvent than necessary is used so the solution is not saturated. If the impure compound contains an impurity which is insoluble in the solvent it may then be removed by filtration and then allowing the solution to crystallize. In addition, if the impure compound contains traces of coloured material that are not native to the compound, it may be removed by adding a small amount of decolorizing agent e.g. activating charcoal to the hot solution, filtering it and then allowing it to crystallize. Usually crystallization spontaneously occurs upon cooling the solution. If it is not, crystallization may be induced by cooling the solution below room temperature or by adding a single crystal of pure material (a seed crystal). Recrystallisation can also be carried out and/or the yield optimized by the use of an anti-solvent or co-solvent. In this case, the compound is dissolved in a suitable solvent at elevated temperature, filtered and then an additional solvent in which the required compound has low solubility is added to aid crystallization. The crystals are then typically isolated using vacuum filtration, washed and then dried, for example, in an oven or via desiccation.

[0511] Other examples of methods for purification include sublimation, which includes an heating step under vacuum for example using a cold finger, and crystallization from melt (Crystallization Technology Handbook 2nd Edition, edited by A. Mersmann, 2001).

BIOLOGICAL EFFECTS



[0512] It is envisaged that the compound of the invention will be useful in medicine or therapy. The compounds of the invention, subgroups and examples thereof, have been shown to inhibit the interaction of p53 with MDM2. Such inhibition leads to cell proliferative arrest and apoptosis, which may be useful in preventing or treating disease states or conditions described herein, for example the diseases and conditions discussed below and the diseases and conditions described in the "Background of the Invention" section above in which p53 and MDM2 play a role. Thus, for example, it is envisaged that the compounds of the invention may be useful in alleviating or reducing the incidence of cancer.

[0513] The compounds of the present invention may be useful for the treatment of the adult population. The compounds of the present invention may be useful for the treatment of the pediatric population.

[0514] The compounds of the present invention have been shown to be good inhibitors of the formation of MDM2-p53 complex. The antagonist compounds of formula (I) are capable of binding to MDM2 and exhibiting potency for MDM2. The efficacies of the compounds of the present invention have been determined against MDM2/p53 using the assay protocol described herein and other methods known in the art. More particularly, the compounds of the formula (I) and sub-groups thereof have affinity for MDM2/p53.

[0515] Certain compounds of the invention are those having IC50 values of less than 0.1 µM in particular less than 0.01 or 0.001 µM.

[0516] MDM2/p53 function has been implicated in many diseases due to its role in a variety of process for example vascular remodelling and antiangiogenic processes and regulation of metabolic pathways, as well as in oncogenesis. As a consequence of their affinity for MDM2 it is anticipated that the compounds may prove useful in treating or preventing a range of diseases or conditions including autoimmune conditions; diabetes mellitus; chronic inflammatory diseases, for example lupus nephritis, systemic lupus erythematosus (SLE), autoimmune mediated glomerulonephritis, rheumatoid arthritis, psoriasis, inflammatory bowel disease, autoimmune diabetes mellitus, Eczema hypersensitivity reactions, asthma, COPD, rhinitis, and upper respiratory tract disease; hyperkeratotic diseases such as autosomal recessive congenital ichthyosis (ARCI); kidney diseases including glomerular disorders, chronic kidney disease (CKD) renal inflammation, podocyte loss, glomerulosclerosis, proteinuria, and progressive kidney disease; cardiovascular diseases for example cardiac hypertrophy, restenosis, arrhythmia, atherosclerosis; ischemic injury associated myocardial infarctions, vascular injury, stroke and reperfusion injury; vascular proliferative diseases; ocular diseases such as age-related macular degeneration in particular wet form of age-related macular degeneration, ischemic proliferative retinopathies such as retinopathy of prematurity (ROP) and diabetic retinopathy, and hemangioma.

[0517] As a consequence of their affinity for MDM2 it is anticipated that the compounds may prove useful in treating or preventing proliferative disorders such as cancers.

[0518] Examples of cancers (and their benign counterparts) which may be treated (or inhibited) include, but are not limited to tumours of epithelial origin (adenomas and carcinomas of various types including adenocarcinomas, squamous carcinomas, transitional cell carcinomas and other carcinomas) such as carcinomas of the bladder and urinary tract, breast, gastrointestinal tract (including the esophagus, stomach (gastric), small intestine, colon, bowel, colorectal, rectum and anus), liver (hepatocellular carcinoma), gall bladder and biliary system, exocrine pancreas, kidney (for example renal cell carcinoma), lung (for example adenocarcinomas, small cell lung carcinomas, non-small cell lung carcinomas, bronchioalveolar carcinomas and mesotheliomas), head and neck (for example cancers of the tongue, buccal cavity, larynx, pharynx, nasopharynx, tonsil, salivary glands, nasal cavity and paranasal sinuses), ovary, fallopian tubes, peritoneum, vagina, vulva, penis, testes, cervix, myometrium, endometrium, thyroid (for example thyroid follicular carcinoma), brain, adrenal, prostate, skin and adnexae (for example melanoma, basal cell carcinoma, squamous cell carcinoma, keratoacanthoma, dysplastic naevus); haematological malignancies (i.e. leukemias, lymphomas) and premalignant haematological disorders and disorders of borderline malignancy including haematological malignancies and related conditions of lymphoid lineage (for example acute lymphocytic leukemia [ALL], chronic lymphocytic leukemia [CLL], B-cell lymphomas such as diffuse large B-cell lymphoma [DLBCL], follicular lymphoma, Burkitt's lymphoma, mantle cell lymphoma, T-cell lymphomas and leukaemias, natural killer [NK] cell lymphomas, Hodgkin's lymphomas, hairy cell leukaemia, monoclonal gammopathy of uncertain significance, plasmacytoma, multiple myeloma, and post-transplant lymphoproliferative disorders), and haematological malignancies and related conditions of myeloid lineage (for example acute myelogenous leukemia [AML], chronic myelogenous leukemia [CML], chronic myelomonocytic leukemia [CMML], hypereosinophilic syndrome, myeloproliferative disorders such as polycythaemia vera, essential thrombocythaemia and primary myelofibrosis, myeloproliferative syndrome, myelodysplastic syndrome, and promyelocytic leukemia); tumours of mesenchymal origin, for example sarcomas of soft tissue, bone or cartilage such as osteosarcomas, fibrosarcomas, chondrosarcomas, rhabdomyosarcomas, leiomyosarcomas, liposarcomas, angiosarcomas, Kaposi's sarcoma, Ewing's sarcoma, synovial sarcomas, epithelioid sarcomas, gastrointestinal stromal tumours, benign and malignant histiocytomas, and dermatofibrosarcoma protuberans; tumours of the central or peripheral nervous system (for example astrocytomas (e.g. gliomas), neuromas and glioblastomas, meningiomas, ependymomas, pineal tumours and schwannomas); endocrine tumours (for example pituitary tumours, adrenal tumours, islet cell tumours, parathyroid tumours, carcinoid tumours and medullary carcinoma of the thyroid); ocular and adnexal tumours (for example retinoblastoma); germ cell and trophoblastic tumours (for example teratomas, seminomas, dysgerminomas, hydatidiform moles and choriocarcinomas); and paediatric and embryonal tumours (for example medulloblastoma, neuroblastoma, Wilms tumour, and primitive neuroectodermal tumours); or syndromes, congenital or otherwise, which leave the patient susceptible to malignancy (for example Xeroderma Pigmentosum).

[0519] Growth of cells is a closely controlled function. Cancer, a condition of abnormal cell growth, results when cells replicate in an uncontrolled manner (increasing in number), uncontrollably grow (getting larger) and/or experience reduced cell death by apoptosis (programmed cell death), necrosis, or annoikis. In one embodiment abnormal cell growth is selected from uncontrolled cell proliferation, excessive cell growth or reduced programmed cell death. In particular, the condition or disease of abnormal cell growth is a cancer.

[0520] Thus, in the pharmaceutical compositions, uses or methods of this invention for treating a disease or condition comprising abnormal cell growth (i.e. uncontrolled and/or rapid cell growth), the disease or condition comprising abnormal cell growth in one embodiment is a cancer.

[0521] Many diseases are characterized by persistent and unregulated angiogenesis. Chronic proliferative diseases are often accompanied by profound angiogenesis, which can contribute to or maintain an inflammatory and/or proliferative state, or which leads to tissue destruction through the invasive proliferation of blood vessels. Tumour growth and metastasis have been found to be angiogenesis-dependent. Compounds of the invention may therefore be useful in preventing and disrupting initiation of tumour angiogenesis.

[0522] Angiogenesis is generally used to describe the development of new or replacement blood vessels, or neovascularisation. It is a necessary and physiological normal process by which vasculature is established in the embryo. Angiogenesis does not occur, in general, in most normal adult tissues, exceptions being sites of ovulation, menses and wound healing. Many diseases, however, are characterized by persistent and unregulated angiogenesis. For instance, in arthritis, new capillary blood vessels invade the joint and destroy cartilage. In diabetes (and in many different eye diseases), new vessels invade the macula or retina or other ocular structures, and may cause blindness. The process of atherosclerosis has been linked to angiogenesis. Tumor growth and metastasis have been found to be angiogenesis-dependent. The compounds may be beneficial in the treatment of diseases such as cancer and metastasis, ocular diseases, arthritis and hemangioma.

[0523] Therefore, the compounds of the invention may be useful in the treatment of metastasis and metastatic cancers. Metastasis or metastatic disease is the spread of a disease from one organ or part to another non-adjacent organ or part. The cancers which can be treated by the compounds of the invention include primary tumours (i.e. cancer cells at the originating site), local invasion (cancer cells which penetrate and infiltrate surrounding normal tissues in the local area), and metastatic (or secondary) tumours ie. tumours that have formed from malignant cells which have circulated through the bloodstream (haematogenous spread) or via lymphatics or across body cavities (trans-coelomic) to other sites and tissues in the body. In particular, the compounds of the invention may be useful in the treatment of metastasis and metastatic cancers.

[0524] In one embodiment the haematological malignancies is a leukaemia. In another embodiment the haematological malignancies is a lymphoma. In one embodiment the cancer is AML. In another embodiment the cancer is CLL.

[0525] In one embodiment the compound of the invention is for use in the prophylaxis or treatment of leukemia, such as acute or chronic leukaemia, in particular acute myeloid leukaemia (AML), acute lymphocytic leukaemia (ALL), chronic lymphocytic leukaemia (CLL), or chronic myeloid leukemia (CML). In one embodiment the compound of the invention is for use in the prophylaxis or treatment of lymphoma, such as acute or chronic lymphoma, in particular Burkitt lymphoma, Hodgkin lymphoma, non-Hodgkin lymphoma or difuse large B-cell lymphoma.

[0526] In one embodiment the compound of the invention is for use in the prophylaxis or treatment of acute myeloid leukaemia (AML) or acute lymphocytic leukaemia (ALL).

[0527] One embodiment includes a compound of the invention for use in the prophylaxis or treatment of cancer in a patient selected from a sub-population possessing cancers which are p53 wild-type or have an MDM2 amplification

[0528] The cancers may be cancers which are sensitive to treatment with MDM2 inhibitors. The cancers may be cancers which overexpress MDM2. The cancer may be cancers which are p53 wild-type.

[0529] Particular cancers include those with an MDM2 amplification and/or MDM2 overexpression, for example, hepatocellular carcinoma, lung, sarcomas, osteosarcomas, and Hodgkin disease.

[0530] Particular cancers include those with wild-type p53. Particulars cancers include those cancer cells with wild-type p53, particularly but not exclusively, if MDM2 is highly expressed.

[0531] In one embodiment the cancer is a p53 functional tumours. In one embodiment this disease to be treated is p53 functional solid and haematological malignancies. In another emboidment the patient to be treated has p53 mutant tumour for example AML patients with p53 mutant tumour.

[0532] In one embodiment the cancer is a tumour of the brain, for example glioma, or neuroblastoma.

[0533] In one embodiment the cancer is a cancer of the skin, for example melanoma.

[0534] In one embodiment the cancer is a cancer of the lung, for example mesothelioma. In one embodiment the mesothelioma is malignant peritoneal mesothelioma or malignant pleural mesothelioma.

[0535] In one embodiment the cancer is a cancer of the gastrointestinal tract, for example GIST, gastric, colorectal or bowel.

[0536] In one embodiment the cancer is osteosarcoma.

[0537] In one embodiment the cancer is liposarcoma.

[0538] In one embodiment the cancer is Ewing's sarcoma.

[0539] In one embodiment, the cancer is liposarcoma, soft tissue sarcoma, osteosarcoma, oesophageal cancer, and certain paediatric malignancies including B-cell malignancies.

[0540] In one embodiment, the cancer is colorectal, breast, lung and brain

[0541] In one embodiment, the cancer is a paediatric cancer.

[0542] Whether a particular cancer is one which is sensitive to MDM2 inhibitors, may be determined by a method as set out in the section headed "Methods of Diagnosis".

[0543] A further aspect provides the use of a compound for the manufacture of a medicament for the treatment of a disease or condition as described herein, in particular cancer.

[0544] Certain cancers are resistant to treatment with particular drugs. This can be due to the type of the tumour (most common epithelial malignancies are inherently chemoresistant and prostate is relatively resistant to currently available regimens of chemotherapy or radiation therapy) or resistance can arise spontaneously as the disease progresses or as a result of treatment. In this regard, references to prostate includes prostate with resistance towards anti-androgen therapy, in particular abiraterone or enzalutamide, or castrate-resistant prostate. Similarly references to multiple myeloma includes bortezomib-insensitive multiple myeloma or refractory multiple myeloma and references to chronic myelogenous leukemia includes imitanib-insensitive chronic myelogenous leukemia and refractory chronic myelogenous leukemia. In this regard, references to mesothelioma includes mesothelioma with resistance towards topoisomerase poisons, alkylating agents, antitubulines, antifolates, platinum compounds and radiation therapy, in particular cisplatin-resistant mesothelioma.

[0545] The compounds may also be useful in the treatment of tumour growth, pathogenesis, resistance to chemo- and radio-therapy by sensitising cells to chemotherapy and as an anti-metastatic agent.

[0546] Therapeutic anticancer interventions of all types necessarily increase the stresses imposed on the target tumour cells. Inhibitors of MDM2/p53 represent a class of chemotherapeutics with the potential for: (i) sensitizing malignant cells to anticancer drugs and/or treatments; (ii) alleviating or reducing the incidence of resistance to anticancer drugs and/or treatments; (iii) reversing resistance to anticancer drugs and/or treatments; (iv) potentiating the activity of anticancer drugs and/or treatments; (v) delaying or preventing the onset of resistance to anticancer drugs and/or treatments.

[0547] In one embodiment the invention provides a compound for use in the treatment of a disease or condition which is mediated by MDM2. In a further embodiment the disease or condition which is mediated by MDM2 is a cancer which is characterised by overexpression and/or increased activity of MDM2, or high copy number MDM2 and/or wildtype p53.

[0548] A further aspect provides the use of a compound for the manufacture of a medicament for the treatment of a disease or condition as decribed herein, in particular cancer.

[0549] In one embodiment there is provided a compound for use in the prophylaxis or treatment of a disease or condition mediated by MDM2/p53. In one embodiment there is provided a compound for inhibiting the interaction between of MDM2 protein with p53.

[0550] In one embodiment there is provided a pharmaceutical composition comprising an effective amount of at least one compound as defined. In a further aspect of the present invention, there is provided a compound as defined in the present

METHODS OF DIAGNOSIS



[0551] Prior to administration of a compound of the formula (I), a patient may be screened to determine whether a disease or condition from which the patient is or may be suffering is one which would be susceptible to treatment with a compound which inhibits Mdm2/p53. The term 'patient' includes human and veterinary subjects such as primates, in particular human patients.

[0552] For example, a biological sample taken from a patient may be analysed to determine whether a condition or disease, such as cancer, that the patient is or may be suffering from is one which is characterised by a genetic abnormality or abnormal protein expression which leads to up-regulation of the levels of MDM2 or to upregulation of a biochemical pathway downstream of MDM2/p53.

[0553] Examples of such abnormalities that result in activation or sensitisation of MDM2, loss of, or inhibition of regulatory pathways impacting on MDM2 expression, up-regulation of receptors or their ligands, cytogenetic aberrations or presence of mutant variants of the receptors or ligands. Tumours with up-regulation of MDM2/p53, in particular over-expression of MDM2 or exhibit wild-type p53, may be particularly sensitive to inhibitors of MDM2/p53. For example, amplification of MDM2 and/or deletion of its negative regulator such as p14ARF has been identified in a range of cancers as discussion in the Introduction section.

[0554] The term up-regulation includes elevated expression or over-expression, including gene amplification (i.e. multiple gene copies), cytogenetic aberration and increased expression by a transcriptional or post-translational effect. Thus, the patient may be subjected to a diagnostic test to detect a marker characteristic of up-regulation of MDM2. The term diagnosis includes screening. By marker we include genetic markers including, for example, the measurement of DNA composition to identify presence of mutations in p53 or amplification MDM2 or deletion (loss) of p14ARF. The term marker also includes markers which are characteristic of up regulation of MDM2/p53, including protein levels, protein state and mRNA levels of the aforementioned proteins. Gene amplification includes greater than 7 copies, as well as gains of between 2 and 7 copies.

[0555] The diagnostic tests and screens are typically conducted on a biological sample (i.e. body tissue or body fluids) selected from tumour biopsy samples, blood samples (isolation and enrichment of shed tumour cells), cerebrospinal fluid, plasma, serum, saliva, stool biopsies, sputum, chromosome analysis, pleural fluid, peritoneal fluid, buccal smears, skin biopsy or urine.

[0556] Methods of identification and analysis of cytogenetic aberration, genetic amplification, mutations and up-regulation of proteins are known to a person skilled in the art. Screening methods could include, but are not limited to, standard methods such as DNA sequence analysis by conventional Sanger or next-generation sequencing methods, reverse-transcriptase polymerase chain reaction (RT-PCR), RNA sequencing (RNAseq), nanostring hybridisation proximity RNA nCounter assays, or in-situ hybridization such as fluorescence in situ hybridization (FISH) or allele-specific polymerase chain reaction (PCR),.

[0557] In screening by RT-PCR, the level of mRNA in the tumour is assessed by creating a cDNA copy of the mRNA followed by amplification of the cDNA by PCR. Methods of PCR amplification, the selection of primers, and conditions for amplification, are known to a person skilled in the art. Nucleic acid manipulations and PCR are carried out by standard methods, as described for example in Ausubel, F.M. et al., eds. (2004) Current Protocols in Molecular Biology, John Wiley & Sons Inc., or Innis, M.A. et al., eds. (1990) PCR Protocols: a guide to methods and applications, Academic Press, San Diego. Reactions and manipulations involving nucleic acid techniques are also described in Sambrook et al., (2001), 3rd Ed, Molecular Cloning: A Laboratory Manual, Cold Spring Harbor Laboratory Press. Alternatively a commercially available kit for RT-PCR (for example Roche Molecular Biochemicals) may be used, or methodology as set forth in United States patents 4,666,828; 4,683,202; 4,801,531; 5,192,659, 5,272,057, 5,882,864, and 6,218,529 and incorporated herein by reference. An example of an in-situ hybridisation technique for assessing mRNA expression would be fluorescence in-situ hybridisation (FISH) (see Angerer (1987) Meth. Enzymol., 152: 649).

[0558] Generally, in situ hybridization comprises the following major steps: (1) fixation of tissue to be analyzed; (2) prehybridization treatment of the sample to increase accessibility of target nucleic acid, and to reduce nonspecific binding; (3) hybridization of the mixture of nucleic acids to the nucleic acid in the biological structure or tissue; (4) post-hybridization washes to remove nucleic acid fragments not bound in the hybridization, and (5) detection of the hybridized nucleic acid fragments. The probes used in such applications are typically labelled, for example, with radioisotopes or fluorescent reporters. Certain probes are sufficiently long, for example, from about 50, 100, or 200 nucleotides to about 1000 or more nucleotides, to enable specific hybridization with the target nucleic acid(s) under stringent conditions. Standard methods for carrying out FISH are described in Ausubel, F.M. et al., eds. (2004) Current Protocols in Molecular Biology, John Wiley & Sons Inc and Fluorescence In Situ Hybridization: Technical Overview by John M. S. Bartlett in Molecular Diagnosis of Cancer, Methods and Protocols, 2nd ed.; ISBN: 1-59259-760-2; March 2004, pps. 077-088; Series: Methods in Molecular Medicine.

[0559] Methods for gene expression profiling are described by (DePrimo et al. (2003), BMC Cancer, 3:3). Briefly, the protocol is as follows: double-stranded cDNA is synthesized from total RNA using a (dT)24 oligomer for priming first-strand cDNA synthesis from polyadenylated mRNA, followed by second strand cDNA synthesis with random hexamer primers. The double-stranded cDNA is used as a template for in vitro transcription of cRNA using biotinylated ribonucleotides. cRNA is chemically fragmented according to protocols described by Affymetrix (Santa Clara, CA, USA), and then hybridized overnight to gene-specific oligonucleotide probes on Human Genome Arrays. Alternatively, single nucleotide polymorphism (SNP) arrays, a type of DNA microarray, can be used to detect polymorphisms within a population.

[0560] Alternatively, the protein products expressed from the mRNAs may be assayed by immunohistochemistry of tumour samples, solid phase immunoassay with microtitre plates, Western blotting, 2-dimensional SDS-polyacrylamide gel electrophoresis, ELISA, flow cytometry and other methods known in the art for detection of specific proteins e.g. capillary electrophoresis. Detection methods would include the use of site specific antibodies. The skilled person will recognize that all such well-known techniques can be used for detection of upregulation of MDM2 and p53, detection of MDM2 or p53 variants or mutants, or loss of negative regulators of MDM2 in the present case.

[0561] Abnormal levels of proteins such as MDM2 or p53 can be measured using standard protein assays, for example, those assays described herein. Elevated levels or overexpression could also be detected in a tissue sample, for example, a tumour tissue by measuring the protein levels with an assay such as that from Chemicon International. The protein of interest would be immunoprecipitated from the sample lysate and its levels measured. Assay methods also include the use of markers.

[0562] In other words, p53 and MDM2 overexpression can be measured by tumour biopsy.

[0563] Methods for assessing gene copy changes include techniques commoly used in cytogenetic laboratories such as MLPA (Multiplex Ligation-dependent Probe Amplification) a multiplex PCR method detecting abnormal copy numbers, or other PCR techniques which can detect gene amplification, gain and deletion.

[0564] Ex-functional assays could also be utilised where appropriate, for example measurement of circulating leukemia cells in a cancer patient, to assess the response to challenge with an MDM2/p53 inhibitor.

[0565] Therefore all of these techniques could also be used to identify tumours particularly suitable for treatment with the compounds of the invention.

[0566] Therefore in a further aspect of the invention includes use of a compound according to the invention for the manufacture of a medicament for the treatment or prophylaxis of a disease state or condition in a patient who has been screened and has been determined as suffering from, or being at risk of suffering from, a disease or condition which would be susceptible to treatment with an MDM2/p53 inhibitor.

[0567] Another aspect of the invention includes a compound of the invention for use in the prophylaxis or treatment of cancer in a patient selected from a sub-population possessing amplification of MDM2.

[0568] Another aspect of the invention includes a compound of the invention for use in the prophylaxis or treatment of cancer in a patient selected from a sub-population possessing p53 wild-type.

[0569] Another aspect of the invention includes a compound of the invention for use in the prophylaxis or treatment of cancer in a patient possessing loss of a MDM2 negative regulator such as p14ARF.

[0570] MRI determination of vessel normalization (e.g. using MRI gradient echo, spin echo, and contrast enhancement to measure blood volume, relative vessel size, and vascular permeability) in combination with circulating biomarkers may also be used to identify patients suitable for treatment with a compound of the invention.

[0571] Also disclosed herein is a method for the diagnosis and treatment of a disease state or condition mediated by MDM2/p53, which method comprises (i) screening a patient to determine whether a disease or condition from which the patient is or may be suffering is one which would be susceptible to treatment with MDM2/p53 inhibitor; and (ii) where it is indicated that the disease or condition from which the patient is thus susceptible, thereafter administering to the patient a compound of formula (I) and sub-groups or examples thereof as defined herein.

Advantages of Compounds of the Invention



[0572] The compounds of the formula (I) have a number of advantages over prior art compounds. Compounds of the invention may have particular advantage in one or more of the following aspects:
  1. (i) Superior potency;
  2. (ii) Superior in vivo efficacy
  3. (iii) Superior PK;
  4. (iv) Superior metabolic stability;
  5. (v) Superior oral bioavailabilty; and
  6. (vi) Superior physiochemical properties.

Superior potency and in vivo efficacy



[0573] The compounds of the formula (I) have increased affinity for MDM2 and in particular increased cell potency against cell lines known to be sensitive to MDM2 antagonists.

[0574] Enhanced target engagement is a highly desirable property in a pharmaceutical compound as it allows for a reduced dosage of drug and a good separation ('therapeutic window') between MDM2 activity and toxic effects.

[0575] The compounds of the formula (I) have improved cell potency and/or improved selectivity for p53 WT vs mutant p53 cell lines. As a result of increased potency against MDM2 compounds of the invention may have increased in vivo efficacy in cancer cell lines and in vivo models. In addition the compounds show selectivity for MDM2 over MDMX, despite the close sequence, structural and functional similarity between these genetic paralogues.

Superior PK and metabolic stability



[0576] The compounds of the formula (I) may have advantageous ADMET properties for example better metabolic stability (for example as determined with mouse liver microsomes), a better P450 profile, short half-life and/or beneficial clearance (e.g. low or high clearance). It has also been found that many compounds of the formula (I) have an improved PK profile.

[0577] These features could confer the advantage of having more drug available in the systemic circulation to reach the appropriate site of action to exert its therapeutic effect. Increased drug concentrations to exert pharmacological action in tumours potentially leads to improved efficacy which thereby allows reduced dosages to be administered. Thus, the compounds of formula (I) should exhibit reduced dosage requirements and should be more readily formulated and administered.

[0578] This results in a good separation ('therapeutic window') between MDM2 activity and toxic effects. Many compounds of the formula (I) have a reduction in Cmax required for efficacy (due to better MDM2 potency and/or PK).

Superior oral bioavailability



[0579] Potentially the compounds of the invention have physiochemical properties suitable for oral exposure (oral exposure or AUC). In particular, compounds of the formula (I) may exhibit improved oral bioavailability or improved reproducibility of oral absorption. Oral bioavailability can be defined as the ratio (F) of the plasma exposure of a compound when dosed by the oral route to the plasma exposure of the compound when dosed by the intravenous (i.v.) route, expressed as a percentage.

[0580] Compounds having an oral bioavailability (F value) of greater than 10%, 20% or 30%, more particularly greater than 40%, are particularly advantageous in that they may be administered orally rather than, or as well as, by parenteral administration.

Superior physiochemical properties



[0581] The compounds of the formula (I) may have advantageous physiochemical properties in particular chemical stability in acidic conditions and reduced lipophilicity.

[0582] Lipophilicity can be measured using a partition-coefficient (logP) or a distribution-coefficient (logD). The partition coefficient is a ratio of concentrations of un-ionized compound between two immiscible phases (n-octanol and water) at equilibrium whereas the distribution coefficient is the ratio of the sum of the concentrations of all forms of the compound (ionized plus un-ionized) in each of the two phases. High lipophilicity is associated with poor drug like properties such us low aqueous solubility, poor pharmacokinetics properties (low oral bioavailability), undesired drug metabolism and high promiscuity. Compounds with optimal lipophilicity might have greater chances of success in drug development. However redued logP (or calculated logP, clogP) can be challenging to achieve whilst retaining an acceptable level of potency for inhibition of protein-protein interactions (PPIs) due to the lipophilic nature of the targets involved.

PHARMACEUTICAL FORMULATIONS



[0583] While it is possible for the active compound to be administered alone, it is generally presented as a pharmaceutical composition (e.g. formulation).

[0584] Thus, the present invention further provides pharmaceutical compositions, as defined above, and methods of making a pharmaceutical composition comprising (e.g admixing) at least one compound of formula (I) (and sub-groups thereof as defined herein), together with one or more pharmaceutically acceptable excipients and optionally other therapeutic or prophylactic agents as described herein.

[0585] The pharmaceutically acceptable excipient(s) can be selected from, for example, carriers (e.g. a solid, liquid or semi-solid carrier), adjuvants, diluents, fillers or bulking agents, granulating agents, coating agents, release-controlling agents, binding agents, disintegrants, lubricating agents, preservatives, antioxidants, buffering agents, suspending agents, thickening agents, flavouring agents, sweeteners, taste masking agents, stabilisers or any other excipients conventionally used in pharmaceutical compositions. Examples of excipients for various types of pharmaceutical compositions are set out in more detail below.

[0586] The term "pharmaceutically acceptable" as used herein pertains to compounds, materials, compositions, and/or dosage forms which are, within the scope of sound medical judgment, suitable for use in contact with the tissues of a subject (e.g. a human subject) without excessive toxicity, irritation, allergic response, or other problem or complication, commensurate with a reasonable benefit/risk ratio. Each excipient must also be "acceptable" in the sense of being compatible with the other ingredients of the formulation.

[0587] Pharmaceutical compositions containing compounds of the formula (I) can be formulated in accordance with known techniques, see for example, Remington's Pharmaceutical Sciences, Mack Publishing Company, Easton, PA, USA.

[0588] The pharmaceutical compositions can be in any form suitable for oral, parenteral, topical, intranasal, intrabronchial, sublingual, ophthalmic, otic, rectal, intra-vaginal, or transdermal administration. Where the compositions are intended for parenteral administration, they can be formulated for intravenous, intramuscular, intraperitoneal, subcutaneous administration or for direct delivery into a target organ or tissue by injection, infusion or other means of delivery. The delivery can be by bolus injection, short-term infusion or longer term infusion and can be via passive delivery or through the utilisation of a suitable infusion pump or syringe driver.

[0589] Pharmaceutical formulations adapted for parenteral administration include aqueous and non-aqueous sterile injection solutions which may contain anti-oxidants, buffers, bacteriostats, co-solvents, surface active agents, organic solvent mixtures, cyclodextrin complexation agents, emulsifying agents (for forming and stabilizing emulsion formulations), liposome components for forming liposomes, gellable polymers for forming polymeric gels, lyophilisation protectants and combinations of agents for, inter alia, stabilising the active ingredient in a soluble form and rendering the formulation isotonic with the blood of the intended recipient. Pharmaceutical formulations for parenteral administration may also take the form of aqueous and non-aqueous sterile suspensions which may include suspending agents and thickening agents (R. G. Strickly, Solubilizing Excipients in oral and injectable formulations, Pharmaceutical Research, Vol 21(2) 2004, p 201-230).

[0590] The formulations may be presented in unit-dose or multi-dose containers, for example sealed ampoules, vials and prefilled syringes, and may be stored in a freeze-dried (lyophilised) condition requiring only the addition of the sterile liquid carrier, for example water for injections, immediately prior to use. In one embodiment, the formulation is provided as an active pharmaceutical ingredient in a bottle for subsequent reconstitution using an appropriate diluent.

[0591] The pharmaceutical formulation can be prepared by lyophilising a compound of formula (I), or sub-groups thereof. Lyophilisation refers to the procedure of freeze-drying a composition. Freeze-drying and lyophilisation are therefore used herein as synonyms.

[0592] Extemporaneous injection solutions and suspensions may be prepared from sterile powders, granules and tablets.

[0593] Pharmaceutical compositions of the present invention for parenteral injection can also comprise pharmaceutically acceptable sterile aqueous or non-aqueous solutions, dispersions, suspensions or emulsions as well as sterile powders for reconstitution into sterile injectable solutions or dispersions just prior to use. Examples of suitable aqueous and nonaqueous carriers, diluents, solvents or vehicles include water, ethanol, polyols (such as glycerol, propylene glycol, polyethylene glycol, and the like), carboxymethylcellulose and suitable mixtures thereof, vegetable oils (such as sunflower oil, safflower oil, corn oil or olive oil), and injectable organic esters such as ethyl oleate. Proper fluidity can be maintained, for example, by the use of thickening materials such as lecithin, by the maintenance of the required particle size in the case of dispersions, and by the use of surfactants.

[0594] The compositions of the present invention may also contain adjuvants such as preservatives, wetting agents, emulsifying agents, and dispersing agents. Prevention of the action of microorganisms may be ensured by the inclusion of various antibacterial and antifungal agents, for example, paraben, chlorobutanol, phenol, sorbic acid, and the like. It may also be desirable to include agents to adjust tonicity such as sugars, sodium chloride, and the like. Prolonged absorption of the injectable pharmaceutical form may be brought about by the inclusion of agents which delay absorption such as aluminum monostearate and gelatin.

[0595] In one typical embodiment of the invention, the pharmaceutical composition is in a form suitable for i.v. administration, for example by injection or infusion. For intravenous administration, the solution can be dosed as is, or can be injected into an infusion bag (containing a pharmaceutically acceptable excipient, such as 0.9% saline or 5% dextrose), before administration.

[0596] In another typical embodiment, the pharmaceutical composition is in a form suitable for sub-cutaneous (s.c.) administration.

[0597] Pharmaceutical dosage forms suitable for oral administration include tablets (coated or uncoated), capsules (hard or soft shell), caplets, pills, lozenges, syrups, solutions, powders, granules, elixirs and suspensions, sublingual tablets, wafers or patches such as buccal patches.

[0598] Thus, tablet compositions can contain a unit dosage of active compound together with an inert diluent or carrier such as a sugar or sugar alcohol, eg; lactose, sucrose, sorbitol or mannitol; and/or a non-sugar derived diluent such as sodium carbonate, calcium phosphate, calcium carbonate, or a cellulose or derivative thereof such as microcrystalline cellulose (MCC), methyl cellulose, ethyl cellulose, hydroxypropyl methyl cellulose, and starches such as corn starch. Tablets may also contain such standard ingredients as binding and granulating agents such as polyvinylpyrrolidone, disintegrants (e.g. swellable crosslinked polymers such as crosslinked carboxymethylcellulose), lubricating agents (e.g. stearates), preservatives (e.g. parabens), antioxidants (e.g. BHT), buffering agents (for example phosphate or citrate buffers), and effervescent agents such as citrate/bicarbonate mixtures. Such excipients are well known and do not need to be discussed in detail here.

[0599] Tablets may be designed to release the drug either upon contact with stomach fluids (immediate release tablets) or to release in a controlled manner (controlled release tablets) over a prolonged period of time or with a specific region of the GI tract.

[0600] Capsule formulations may be of the hard gelatin or soft gelatin variety and can contain the active component in solid, semi-solid, or liquid form. Gelatin capsules can be formed from animal gelatin or synthetic or plant derived equivalents thereof.

[0601] The solid dosage forms (eg; tablets, capsules etc.) can be coated or un-coated. Coatings may act either as a protective film (e.g. a polymer, wax or varnish) or as a mechanism for controlling drug release or for aesthetic or identification purposes.. The coating (e.g. a Eudragit type polymer) can be designed to release the active component at a desired location within the gastro-intestinal tract. Thus, the coating can be selected so as to degrade under certain pH conditions within the gastrointestinal tract, thereby selectively release the compound in the stomach or in the ileum, duodenum, jejenum or colon.

[0602] Instead of, or in addition to, a coating, the drug can be presented in a solid matrix comprising a release controlling agent, for example a release delaying agent which may be adapted to release the compound in a controlled manner in the gastrointestinal tract. Alternatively the drug can be presented in a polymer coating e.g. a polymethacrylate polymer coating, which may be adapted to selectively release the compound under conditions of varying acidity or alkalinity in the gastrointestinal tract. Alternatively, the matrix material or release retarding coating can take the form of an erodible polymer (e.g. a maleic anhydride polymer) which is substantially continuously eroded as the dosage form passes through the gastrointestinal tract. In another alternative, the coating can be designed to disintegrate under microbial action in the gut. As a further alternative, the active compound can be formulated in a delivery system that provides osmotic control of the release of the compound. Osmotic release and other delayed release or sustained release formulations (for example formulations based on ion exchange resins) may be prepared in accordance with methods well known to those skilled in the art.

[0603] The compound of formula (I) may be formulated with a carrier and administered in the form of nanoparticles, the increased surface area of the nanoparticles assisting their absorption. In addition, nanoparticles offer the possibility of direct penetration into the cell. Nanoparticle drug delivery systems are described in "Nanoparticle Technology for Drug Delivery", edited by Ram B Gupta and Uday B. Kompella, Informa Healthcare, ISBN 9781574448573, published 13th March 2006. Nanoparticles for drug delivery are also described in J. Control. Release, 2003, 91 (1-2), 167-172, and in Sinha et al., Mol. Cancer Ther. August 1, (2006) 5, 1909.

[0604] The pharmaceutical compositions typically comprise from approximately 1% (w/w) to approximately 95% active ingredient and from 99% (w/w) to 5% (w/w) of a pharmaceutically acceptable excipient or combination of excipients. Typically, the compositions comprise from approximately 20% (w/w) to approximately 90%,% (w/w) active ingredient and from 80% (w/w) to 10% of a pharmaceutically acceptable excipient or combination of excipients. The pharmaceutical compositions comprise from approximately 1% to approximately 95%, typically from approximately 20% to approximately 90%, active ingredient. Pharmaceutical compositions according to the invention may be, for example, in unit dose form, such as in the form of ampoules, vials, suppositories, pre-filled syringes, dragees, tablets or capsules.

[0605] The pharmaceutically acceptable excipient(s) can be selected according to the desired physical form of the formulation and can, for example, be selected from diluents (e.g solid diluents such as fillers or bulking agents; and liquid diluents such as solvents and co-solvents), disintegrants, buffering agents, lubricants, flow aids, release controlling (e.g. release retarding or delaying polymers or waxes) agents, binders, granulating agents, pigments, plasticizers, antioxidants, preservatives, flavouring agents, taste masking agents, tonicity adjusting agents and coating agents.

[0606] The skilled person will have the expertise to select the appropriate amounts of ingredients for use in the formulations. For example tablets and capsules typically contain 0-20% disintegrants, 0-5% lubricants, 0-5% flow aids and/or 0-99% (w/w) fillers/ or bulking agents (depending on drug dose). They may also contain 0-10% (w/w) polymer binders, 0-5% (w/w) antioxidants, 0-5% (w/w) pigments. Slow release tablets would in addition contain 0-99% (w/w) polymers (depending on dose). The film coats of the tablet or capsule typically contain 0-10% (w/w) release-controlling (e.g. delaying) polymers, 0-3% (w/w) pigments, and/or 0-2% (w/w) plasticizers.

[0607] Parenteral formulations typically contain 0-20% (w/w) buffers, 0-50% (w/w) cosolvents, and/or 0-99% (w/w) Water for Injection (WFI) (depending on dose and if freeze dried). Formulations for intramuscular depots may also contain 0-99% (w/w) oils.

[0608] Pharmaceutical compositions for oral administration can be obtained by combining the active ingredient with solid carriers, if desired granulating a resulting mixture, and processing the mixture, if desired or necessary, after the addition of appropriate excipients, into tablets, dragee cores or capsules. It is also possible for them to be incorporated into a polymer or waxy matrix that allow the active ingredients to diffuse or be released in measured amounts.

[0609] The compounds of the invention can also be formulated as solid dispersions. Solid dispersions are homogeneous extremely fine disperse phases of two or more solids. Solid solutions (molecularly disperse systems), one type of solid dispersion, are well known for use in pharmaceutical technology (see (Chiou and Riegelman, J. Pharm. Sci., 60, 1281-1300 (1971)) and are useful in increasing dissolution rates and increasing the bioavailability of poorly water-soluble drugs.

[0610] This invention also provides solid dosage forms comprising the solid solution described herein. Solid dosage forms include tablets, capsules, chewable tablets and dispersible or effervescent tablets. Known excipients can be blended with the solid solution to provide the desired dosage form. For example, a capsule can contain the solid solution blended with (a) a disintegrant and a lubricant, or (b) a disintegrant, a lubricant and a surfactant. In addition a capsule can contain a bulking agent, such as lactose or microcrystalline cellulose. A tablet can contain the solid solution blended with at least one disintegrant, a lubricant, a surfactant, a bulking agent and a glidant. A chewable tablet can contain the solid solution blended with a bulking agent, a lubricant, and if desired an additional sweetening agent (such as an artificial sweetener), and suitable flavours. Solid solutions may also be formed by spraying solutions of drug and a suitable polymer onto the surface of inert carriers such as sugar beads ('nonpareils'). These beads can subsequently be filled into capsules or compressed into tablets.

[0611] The pharmaceutical formulations may be presented to a patient in "patient packs" containing an entire course of treatment in a single package, usually a blister pack. Patient packs have an advantage over traditional prescriptions, where a pharmacist divides a patient's supply of a pharmaceutical from a bulk supply, in that the patient always has access to the package insert contained in the patient pack, normally missing in patient prescriptions. The inclusion of a package insert has been shown to improve patient compliance with the physician's instructions.

[0612] Compositions for topical use and nasal delivery include ointments, creams, sprays, patches, gels, liquid drops and inserts (for example intraocular inserts). Such compositions can be formulated in accordance with known methods.

[0613] Examples of formulations for rectal or intra-vaginal administration include pessaries and suppositories which may be, for example, formed from a shaped moldable or waxy material containing the active compound. Solutions of the active compound may also be used for rectal administration.

[0614] Compositions for administration by inhalation may take the form of inhalable powder compositions or liquid or powder sprays, and can be administrated in standard form using powder inhaler devices or aerosol dispensing devices. Such devices are well known. For administration by inhalation, the powdered formulations typically comprise the active compound together with an inert solid powdered diluent such as lactose.

[0615] The compounds of the formula (I) will generally be presented in unit dosage form and, as such, will typically contain sufficient compound to provide a desired level of biological activity. For example, a formulation may contain from 1 nanogram to 2 grams of active ingredient, e.g. from 1 nanogram to 2 milligrams of active ingredient. Within these ranges, particular sub-ranges of compound are 0.1 milligrams to 2 grams of active ingredient (more usually from 10 milligrams to 1 gram, e.g. 50 milligrams to 500 milligrams), or 1 microgram to 20 milligrams (for example 1 microgram to 10 milligrams, e.g. 0.1 milligrams to 2 milligrams of active ingredient).

[0616] For oral compositions, a unit dosage form may contain from 1 milligram to 2 grams, more typically 10 milligrams to 1 gram, for example 50 milligrams to 1 gram, e.g. 100 miligrams to 1 gram, of active compound.

[0617] The active compound will be administered to a patient in need thereof (for example a human or animal patient) in an amount sufficient to achieve the desired therapeutic effect.

METHODS OF TREATMENT



[0618] The compounds of the formula (I) and sub-groups as defined herein may be useful in the prophylaxis or treatment of a range of disease states or conditions mediated by MDM2/p53. Examples of such disease states and conditions are set out above.

[0619] The compounds are generally administered to a subject in need of such administration, for example a human or animal patient, typically a human.

[0620] The compounds will typically be administered in amounts that are therapeutically or prophylactically useful and which generally are non-toxic. However, in certain situations (for example in the case of life threatening diseases), the benefits of administering a compound of the formula (I) may outweigh the disadvantages of any toxic effects or side effects, in which case it may be considered desirable to administer compounds in amounts that are associated with a degree of toxicity.

[0621] The compounds may be administered over a prolonged term to maintain beneficial therapeutic effects or may be administered for a short period only. Alternatively they may be administered in a continuous manner or in a manner that provides intermittent dosing (e.g. a pulsatile manner).

[0622] A typical daily dose of the compound of formula (I) can be in the range from 100 picograms to 100 milligrams per kilogram of body weight, more typically 5 nanograms to 25 milligrams per kilogram of bodyweight, and more usually 10 nanograms to 15 milligrams per kilogram (e.g. 10 nanograms to 10 milligrams, and more typically 1 microgram per kilogram to 20 milligrams per kilogram, for example 1 microgram to 10 milligrams per kilogram) per kilogram of bodyweight although higher or lower doses may be administered where required. The compound of the formula (I) can be administered on a daily basis or on a repeat basis every 2, or 3, or 4, or 5, or 6, or 7, or 10 or 14, or 21, or 28 days for example.

[0623] Dosages may also be expressed as the amount of drug administered relative to the body surface area of the patient (mg/m2). A typical daily dose of the compound of formula (I) can be in the range from 3700 pg/m2 to 3700 mg/m2, more typically 185 ng/m2 to 925 mg/m2, and more usually 370 ng/m2 to 555 mg/m2 (e.g. 370 ng/m2 to 370 mg/m2, and more typically 37 mg/m2 to 740 mg/m2, for example 37 mg/m2 to 370 mg/m2) although higher or lower doses may be administered where required. The compound of the formula (I) can be administered on a daily basis or on a repeat basis every 2, or 3, or 4, or 5, or 6, or 7, or 10 or 14, or 21, or 28 days for example.

[0624] The compounds of the invention may be administered orally in a range of doses, for example 0.1 to 5000 mg, or 1 to 1500 mg, 2 to 800 mg, or 5 to 500 mg, e.g. 2 to 200 mg or 10 to 1000 mg, particular examples of doses including 10, 20, 50 and 80 mg. The compound may be administered once or more than once each day. The compound can be administered continuously (i.e. taken every day without a break for the duration of the treatment regimen). Alternatively, the compound can be administered intermittently (i.e. taken continuously for a given period such as a week, then discontinued for a period such as a week and then taken continuously for another period such as a week and so on throughout the duration of the treatment regimen). Examples of treatment regimens involving intermittent administration include regimens wherein administration is in cycles of one week on, one week off; or two weeks on, one week off; or three weeks on, one week off; or two weeks on, two weeks off; or four weeks on two weeks off; or one week on three weeks off - for one or more cycles, e.g. 2, 3, 4, 5, 6, 7, 8, 9 or 10 or more cycles. This discontinuous treatment can also be based upon numbers of days rather than a full week. For example, the treatment can comprise daily dosing for 1 to 6 days, no dosing for 1 to 6 days with this pattern repeating during the treatment protocol. The number of days (or weeks) wherein the compounds of the invention are not dosed do not necessarily have to equal the number of days (or weeks) wherein the compounds of the invention are dosed.

[0625] In one embodiment, the compounds of the invention can be administered in amounts from 3mg/m2 to 125mg/m2 daily. Treatment can be by continuous daily dosing or more usually consist of multiple cycles of treatment separated by treatment breaks. One example of a single treatment cycle is 5 consecutive daily doses followed by 3 weeks without treatment.

[0626] One particular dosing regimen is once a day (e.g. orally) for a week (e.g. 5 days of treatment), followed by a treatment break of 1, 2, or 3 weeks. An alternative dosing regimen is once a week (e.g. orally), for 1, 2, 3 or 4 weeks.

[0627] In one particular dosing schedule, a patient will be given an infusion of a compound of the formula (I) for periods of one hour daily for up to ten days in particular up to five days for one week, and the treatment repeated at a desired interval such as two to four weeks, in particular every three weeks.

[0628] More particularly, a patient may be given an infusion of a compound of the formula (I) for periods of one hour daily for 5 days and the treatment repeated every three weeks.

[0629] In another particular dosing schedule, a patient is given an infusion over 30 minutes to 1 hour followed by maintenance infusions of variable duration, for example 1 to 5 hours, e.g. 3 hours.

[0630] The compounds of the invention can also be administered by bolus or continuous infusion. The compound of the invention can be given daily to once every week, or once every two weeks, or once every three weeks, or once every four weeks during the treatment cycle. If administered daily during a treatment cycle, this daily dosing can be discontinuous over the number of weeks of the treatment cycle: for example, dosed for a week (or a number of days), no dosing for a week (or a number of days, with the pattern repeating during the treatment cycle.

[0631] In a further particular dosing schedule, a patient is given a continuous infusion for a period of 12 hours to 5 days, and in particular a continuous infusion of 24 hours to 72 hours.

[0632] Ultimately, however, the quantity of compound administered and the type of composition used will be commensurate with the nature of the disease or physiological condition being treated and will be at the discretion of the physician.

[0633] It may be beneficial to use a compound of the invention as a single agent or to combine the compound of the invention with another agent which acts via a different mechanism to regulate cell growth thus treating two of the characteristic features of cancer development. Combination experiments can be performed, for example, as described in Chou TC, Talalay P. Quantitative analysis of dose-effect relationships: the combined effects of multiple drugs or enzyme inhibitors. Adv Enzyme Regulat 1984;22: 27-55.

[0634] The compounds as defined herein can be administered as the sole therapeutic agent or they can be administered in combination therapy with one of more other compounds (or therapies) for treatment of a particular disease state, for example a neoplastic disease such as a cancer as hereinbefore defined. For the treatment of the above conditions, the compounds of the invention may be advantageously employed in combination with one or more other medicinal agents, more particularly, with other anti-cancer agents or adjuvants (supporting agents in the therapy) in cancer therapy. Examples of other therapeutic agents or treatments that may be administered together (whether concurrently or at different time intervals) with the compounds of the formula (I) include but are not limited to:
  • Topoisomerase I inhibitors
  • Antimetabolites
  • Tubulin targeting agents
  • DNA binder and topoisomerase II inhibitors
  • Alkylating Agents
  • Monoclonal Antibodies.
  • Anti-Hormones
  • Signal Transduction Inhibitors
  • Proteasome Inhibitors
  • DNA methyl transferase inhibitors
  • Cytokines and retinoids
  • Chromatin targeted therapies
  • Radiotherapy, and,
  • Other therapeutic or prophylactic agents.

Trastuzumab is advantageously administered in a dosage of 1 to 5 mg per square meter (mg/m2) of body surface area, particularly 2 to 4mg/m2 per course of treatment.

[0646] Where the compound of the formula (I) is administered in combination therapy with one, two, three, four or more other therapeutic agents (typically one or two, more typically one), the compounds can be administered simultaneously or sequentially. In the latter case, the two or more compounds will be administered within a period and in an amount and manner that is sufficient to ensure that an advantageous or synergistic effect is achieved. When administered sequentially, they can be administered at closely spaced intervals (for example over a period of 5-10 minutes) or at longer intervals (for example 1, 2, 3, 4 or more hours apart, or even longer periods apart where required), the precise dosage regimen being commensurate with the properties of the therapeutic agent(s). These dosages may be administered for example once, twice or more per course of treatment, which may be repeated for example every 7, 14, 21 or 28 days.

[0647] It will be appreciated that the typical method and order of administration and the respective dosage amounts and regimes for each component of the combination will depend on the particular other medicinal agent and compound of the present invention being administered, their route of administration, the particular tumour being treated and the particular host being treated. The optimum method and order of administration and the dosage amounts and regime can be readily determined by those skilled in the art using conventional methods and in view of the information set out herein.

[0648] The weight ratio of the compound according to the present invention and the one or more other anticancer agent(s) when given as a combination may be determined by the person skilled in the art. Said ratio and the exact dosage and frequency of administration depends on the particular compound according to the invention and the other anticancer agent(s) used, the particular condition being treated, the severity of the condition being treated, the age, weight, gender, diet, time of administration and general physical condition of the particular patient, the mode of administration as well as other medication the individual may be taking, as is well known to those skilled in the art. Furthermore, it is evident that the effective daily amount may be lowered or increased depending on the response of the treated subject and/or depending on the evaluation of the physician prescribing the compounds of the instant invention. A particular weight ratio for the present compound of formula (I) and another anticancer agent may range from 1/10 to 10/1, more in particular from 1/5 to 5/1, even more in particular from 1/3 to 3/1.

[0649] The compounds of the invention may also be administered in conjunction with non-chemotherapeutic treatments such as radiotherapy, photodynamic therapy, gene therapy; surgery and controlled diets. Radiotherapy may be for radical, palliative, adjuvant, neoadjuvant or prophylactic purposes.

[0650] The compounds of the present invention also have therapeutic applications in sensitising tumour cells for radiotherapy and chemotherapy. Hence the compounds of the present invention can be used as "radiosensitizer" and/or "chemosensitizer" or can be given in combination with another "radiosensitizer" and/or "chemosensitizer". In one embodiment the compound of the invention is for use as chemosensitiser.

[0651] The term "radiosensitizer" is defined as a molecule administered to patients in therapeutically effective amounts to increase the sensitivity of the cells to ionizing radiation and/or to promote the treatment of diseases which are treatable with ionizing radiation.

[0652] The term "chemosensitizer" is defined as a molecule administered to patients in therapeutically effective amounts to increase the sensitivity of cells to chemotherapy and/or promote the treatment of diseases which are treatable with chemotherapeutics.

[0653] Many cancer treatment protocols currently employ radiosensitizers in conjunction with radiation of x-rays. Examples of x-ray activated radiosensitizers include, but are not limited to, the following: metronidazole, misonidazole, desmethylmisonidazole, pimonidazole, etanidazole, nimorazole, mitomycin C, RSU 1069, SR 4233, EO9, RB 6145, nicotinamide, 5-bromodeoxyuridine (BUdR), 5-iododeoxyuridine (lUdR), bromodeoxycytidine, fluorodeoxyuridine (FudR), hydroxyurea, cisplatin, and therapeutically effective analogs and derivatives of the same.

[0654] Photodynamic therapy (PDT) of cancers employs visible light as the radiation activator of the sensitizing agent. Examples of photodynamic radiosensitizers include the following, but are not limited to: hematoporphyrin derivatives, Photofrin, benzoporphyrin derivatives, tin etioporphyrin, pheoborbide-a, bacteriochlorophyll-a, naphthalocyanines, phthalocyanines, zinc phthalocyanine, and therapeutically effective analogs and derivatives of the same.

[0655] Radiosensitizers may be administered in conjunction with a therapeutically effective amount of one or more other compounds, including but not limited to: compounds which promote the incorporation of radiosensitizers to the target cells; compounds which control the flow of therapeutics, nutrients, and/or oxygen to the target cells; chemotherapeutic agents which act on the tumour with or without additional radiation; or other therapeutically effective compounds for treating cancer or other diseases.

[0656] Chemosensitizers may be administered in conjunction with a therapeutically effective amount of one or more other compounds, including but not limited to: compounds which promote the incorporation of chemosensitizers to the target cells; compounds which control the flow of therapeutics, nutrients, and/or oxygen to the target cells; chemotherapeutic agents which act on the tumour or other therapeutically effective compounds for treating cancer or other disease. Calcium antagonists, for example verapamil, are found useful in combination with antineoplastic agents to establish chemosensitivity in tumor cells resistant to accepted chemotherapeutic agents and to potentiate the efficacy of such compounds in drug-sensitive malignancies.

[0657] For use in combination therapy with another chemotherapeutic agent, the compound of the formula (I) and one, two, three, four or more other therapeutic agents can be, for example, formulated together in a dosage form containing two, three, four or more therapeutic agents i.e. in a unitary pharmaceutical composition containing all components. In an alternative, the individual therapeutic agents may be formulated separately and presented together in the form of a kit, optionally with instructions for their use.

[0658] In one embodiment the pharmaceutical composition comprises a compound of formula I together with a pharmaceutically acceptable carrier and optionally one or more therapeutic agent(s)

[0659] In another embodiment the invention relates to the use of a combination according to the invention in the manufacture of a pharmaceutical composition for inhibiting the growth of tumour cells.

[0660] In a further embodiment the invention relates to a product containing a compound of formula I and one or more anticancer agent, as a combined preparation for simultaneous, separate or sequential use in the treatment of patients suffering from cancer.

Column chromatography



[0662] Purification using column chromatography can be achieved, for example using a Biotage automated flash purification system with UV monitoring at 298 nm and collection at 254 nm. Biotage automated chromatography pre-packed silica cartridges were used in most cases. Where stated, the purification of some compounds was performed using Biotage C18 reversed phase silica columns, which have octadecyl (end-capped) functionalised silica or Biotage KP-NH cartridges were used for the separation of highly polar compounds, which uses primary amine bonded silica.

[0663] Where necessary, semi-preparative HPLC can be carried out, for example using one of the following machines: (i) Varian Prostar Modular HPLC system with a binary pumping system, UV detector and fraction collector and controlled by Varian Star software. (ii) Agilent 1200 HPLC system with a binary pump, autosampler, fraction collector and diode array detector and controlled by Agilent ChemStation software.

Mass Directed Purification LC-MS System



[0665] Preparative LC-MS is a standard and effective method used for the purification of small organic molecules such as the compounds described herein. The methods for the liquid chromatography (LC) and mass spectrometry (MS) can be varied to provide better separation of the crude materials and improved detection of the samples by MS. Optimisation of the preparative gradient LC method will involve varying columns, volatile eluents and modifiers, and gradients. Methods are well known in the art for optimising preparative LC-MS methods and then using them to purify compounds. Such methods are described in Rosentreter U, Huber U.; Optimal fraction collecting in preparative LC/MS; J Comb Chem.; 2004; 6(2), 159-64 and Leister W, Strauss K, Wisnoski D, Zhao Z, Lindsley C., Development of a custom high-throughput preparative liquid chromatography/mass spectrometer platform for the preparative purification and analytical analysis of compound libraries; J Comb Chem.; 2003; 5(3); 322-9.

[0666] Several systems for purifying compounds via preparative LC-MS are described below although a person skilled in the art will appreciate that alternative systems and methods to those described could be used. In particular, normal phase preparative LC based methods might be used in place of the reverse phase methods described here. Most preparative LC-MS systems utilise reverse phase LC and volatile acidic modifiers, since the approach is very effective for the purification of small molecules and because the eluents are compatible with positive ion electrospray mass spectrometry. Employing other chromatographic solutions e.g. normal phase LC, alternatively buffered mobile phase, basic modifiers etc as outlined in the analytical methods described above could alternatively be used to purify the compounds.

[0673] Columns: A range of commercially available columns - both achiral and chiral - may be used such that, in conjunction with the changes in mobile phase, organic modifier and pH, they enabled the greatest cover in terms of a broad range of selectivity. All columns were used in accordance with the manufacturers recommended operating conditions. Typically 5 micron particle sized columns were used where available. For example, columns from Waters (including but not limited to XBridge Prep Phenyl 5µ OBD 100x19mm, XBridge Prep C18 5µ OBD 100x19mm, Waters Atlantis Prep T3 OBD 5µ 100x19mm and SunFire Prep C18 OBD 5µ 100x19mm), Phenomenex (including but not limited to Synergy MAX-RP and LUX Cellulose-2), Astec (Chirobiotic columns including but not limited to V, V2 and T2) and Diacel® (including but not limited to Chiralpak® AD-H) were available for screening.

[0674] Eluents: Mobile phase eluent was chosen in conjunction with column manufacturers recommended stationary phase limitations in order to optimise a columns separation performance.

[0675] Methods: According to the analytical trace the most appropriate preparative chromatography type was chosen. A typical routine was to run an analytical LC-MS using the type of chromatography (low or high pH) most suited for compound structure. Once the analytical trace showed good chromatography a suitable preparative method of the same type was chosen.

[0676] Solvent: All compounds were usually dissolved in 100% MeOH or 100% DMSO or 90:10 Methanol:Water + 0.2% Formic Acid.

Supercritical Fluid Chromatography (SFC)



[0677] In some cases, final compounds were purified by Supercritcal Fluid Chromatography (SFC) using a Waters Thar Prep100 preparative SFC system (P200 CO2 pump, 2545 modifier pump, 2998 UV/VIS detector, 2767 liquid handler with Stacked Injection Module). The Waters 2767 liquid handler acted as both auto-sampler and fraction collector.

[0678] The column used for the preparative purification of the compounds was a Diacel Chiralpak IA/IB/IC, YMC Amylose / Cellulose C or Phenomenex Lux Cellulose-4 at 5um 20 - 21.2 x 250 mm unless otherwise stated.

[0679] Appropriate isocratic methods were selected based on methanol, ethanol or isopropanol solvent systems under un-modified or basic conditions. The standard method used was typically 5-55% modifier /CO2, 100ml/min, 120 Bar backpressure, 40oC column temperature.

[0680] All compounds were screened analytically prior to the purification step. Each sample was run under both un-modified and basic conditions (5.0ul injection, 5/95 gradient for 5 minutes) across ethanol, methanol and isopropanol. If necessary, secondary screen across extended solvents such as acetonitrile, ethyl acetate and THF may also be considered. A decision was then made by the analyst as to what pH and which isocratic condition to use depending on where the desired product elutes and the separation achieved.

[0681] The modifier used under basic conditions was diethyl amine (0.1% V/V). Occasionally formic acid (0.1% V/V) may be used as an acidic modifier.

[0682] The purification was controlled by Waters Fractionlynx software through monitoring at 210-400nm and triggered a threshold collection value at 260nm unless otherwise started. Collected fractions were analysed by SFC (Waters/Thar SFC systems with Waters SQD). The fractions that contained the desired product were concentrated by vacuum centrifugation.

[0683] From the information provided someone skilled in the art could purify the compounds described herein by preparative LC-MS.

Synthetic Methods



[0684] By following methods similar and/or analogous to general procedures below, the compounds set out below were prepared.

[0685] The following synthetic procedures are provided for illustration of the methods used; for a given preparation or step the precursor used may not necessarily derive from the individual batch synthesised according to the step in the description given.

[0686] Where a compound is described as a mixture of two diastereoisomers / epimers, the configuration of the stereocentre is not specified and is represented by straight lines.

[0687] As understood by a person skilled in the art, compounds synthesised using the protocols as indicated may exist as a solvate e.g. hydrate, and/or contain residual solvent or minor impurities. Compounds isolated as a salt form, may be integer stoichiometric i.e. mono- or di-salts, or of intermediate stoichiometry.

[0688] Some of the compounds below are isolated as the salt, for example depending on the acid used in the purification method. Some compounds are isolated as the free base.

[0689] Compounds containing a single stereocentre (R-configuration) at the 3-position are typically isolated as a single isomer using preparative chiral HPLC (as described in general methods); at (or towards) the final stage of the synthetic sequence. In these cases the stereochemistry at the 3-position is designated in accordance with IUPAC, using 'hashed' or 'solid' wedged lines. Unless stated otherwise, a straight line at a stereocentre indicates the compound exists as a mixture of both isomers.

[0690] An example (3R)-3-(4-chlorophenyl)-2-[(4-chlorophenyl)methyl]-3-{[1-(hydroxymethyl)cyclopropyl]methoxy}-6-(2-hydroxypropan-2-yl)-2,3-dihydro-1H-isoindol-1-one is shown in Figure A.



[0691] Figure A: Example showing purification of 3R-isomer by chiral HPLC

[0692] Compounds containing a second stereocentre (e.g. adjacent to the 6-position) are typically isolated as a single isomer by preparative achiral and/or chiral HPLC. In these cases, the stereochemistry at the 3 position is designated in the usual fashion, using 'hashed' or 'solid' wedged lines. An asterisk (*) at the second stereocentre indicates one (or both) of the diasteroisomers associated with this position was/were isolated separately. For example, the 2 isomers of (3R)-2-[(4-chloro-2-methanesulfonylphenyl)methyl]-3-(4-chlorophenyl)-4-fluoro-6-[1-hydroxy-1-(1-methyl-1H-pyrazol-4-yl)ethyl]-3-[(1-hydroxycyclopropyl)methoxy]-2,3-dihydro-1H-isoindol-1-one were separated by preparative achiral and/or chiral HPLC to give two separate Examples (Figure B).

[0693] Note: Depending on the specific substitution pattern, the numbering system in some analogues may differ, according to the formal convention of nomenclature.



[0694] Figure B: Asterisk (* ) means the two isomers were separated and isolated to give the two diasteroisomeric examples (Example 75 and 76)

[0695] In other cases, isomers were separated at an intermediate stage in the synthesis and only one isomer progressed to the final Example. The relevant isomers can be characterised by either optical rotation of linearly polarized light and/or or relative retention time on a chiral HPLC coloumn. In these cases, an asterisk (*) indicates that the compound was isolated as a single isomer. This is illustrated by Example 80 (Figure C)



[0696] Figure C: Synthesis of Example 80, (3R)-2-[(4-chloro-2-methanesulfonylphenyl)methyl]-3-(4-chlorophenyl)-4-fluoro-6-[1-hydroxy-1-(1-methylpiperidin-4-yl)ethyl]-3-{[1-(hydroxymethyl)cyclopropyl]methoxy}-2,3-dihydro-1H-isoindol-1-one. Example is derived from the levorotary enantiomer of compound (3), followed by a preparative chiral HPLC at the final stage.

[0697] The optical isomers may be characterised by their optical activity (i.e. as + and - isomers, or d and / isomers). The stereocentre can also assigned as "R or S" according to the nomenclature developed by Cahn, Ingold and Prelog, see Advanced Organic Chemistry by Jerry March, 4th Edition, John Wiley & Sons, New York, 1992, pages 109-114, and see also Cahn, Ingold & Prelog, Angew. Chem. Int. Ed. Engl., 1966, 5, 385-415.

[0698] Optical isomers can be separated by a number of techniques including chiral chromatography (chromatography on a chiral support) and such techniques are well known to the person skilled in the art.

[0699] As an alternative to chiral chromatography, optical isomers of basic compounds can be separated by forming diastereoisomeric salts with chiral acids such as (+)-tartaric acid, (-)-pyroglutamic acid, (-)-di-toluoyl-L-tartaric acid, (+)-mandelic acid, (-)-malic acid, and (-)-camphorsulfonic acid, separating the diastereoisomeric salts by preferential crystallisation, and then dissociating the salts to give the individual enantiomer of the free base. Likewise, optical iomers of acidic compounds can be separated by forming diastereoisomeric salts with chiral amines such as Brucine, Cinchonidine, quinine etc.

[0700] Additionally enantiomeric separation can be achieved by covalently linking a enantiomerically pure chiral auxiliary onto the compound and then performing diastereisomer separation using conventional methods such as chromatography. This is then followed by cleavage of the aforementioned covalent linkage to generate the appropriate enantiomerically pure product. Examples could include making menthol esters of an acidic compound.

[0701] Where compounds of the formula (I) exist as two or more optical isomeric forms, one enantiomer in a pair of enantiomers may exhibit advantages over the other enantiomer, for example, in terms of biological activity. Thus, in certain circumstances, it may be desirable to use as a therapeutic agent only one of a pair of enantiomers, or only one of a plurality of diastereoisomers.

[0702] Accordingly, the invention provides compositions containing a compound of the formula (I) having one or more chiral centres, wherein at least 55% (e.g. at least 60%, 65%, 70%, 75%, 80%, 85%, 90% or 95%) of the compound of the formula (I) is present as a single optical isomer (e.g. enantiomer or diastereoisomer). In one general embodiment, 99% or more (e.g. substantially all) of the total amount of the compound of the formula (I) may be present as a single optical isomer (e.g. enantiomer or diastereoisomer).

[0703] Compounds encompassing double bonds can have an E (entgegen) or Z (zusammen) stereochemistry at said double bond. Substituents on bivalent cyclic or (partially) saturated radicals may have either the cis- or trans-configuration. The terms cis and trans when used herein are in accordance with Chemical Abstracts nomenclature (J. Org. Chem. 1970, 35 (9), 2849-2867), and refer to the position of the substituents on a ring moiety.

[0704] Of special interest are those compounds of formula (I) which are stereochemically pure. When a compound of formula (I) is for instance specified as R, this means that the compound is substantially free of the S isomer. If a compound of formula (I) is for instance specified as E, this means that the compound is substantially free of the Z isomer. The terms cis, trans, R, S, E and Z are well known to a person skilled in the art.

BIOLOGICAL ASSAYS


MDM2-p53 interaction using a 96-wellplate binding assay (ELISA)



[1319] The ELISA assay was performed in streptavidin coated plates which were preincubated with 200 µl per well of 1µg ml-1 biotinylated IP3 peptide. The plates were ready to use for MDM2 binding after washing the plate with PBS.

[1320] Compounds and control solutions in DMSO aliquoted in 96-well plates were pre-incubated in a final 2.5-5 % (v/v) DMSO concentration at room temperature (for example 20 °C) for 20 min with 190 µl aliquots of optimized concentrations of in vitro translated MDM2, before transfer of the MDM2-compound mixture to the b-IP3 streptavidin plates, and incubation at 4 °C for 90 min. After washing three times with PBS to remove unbound MDM2, each well was incubated at 20 °C for 1 hour with a TBS-Tween (50mM Tris pH7.5; 150mM NaCl; 0.05% Tween 20 nonionic detergent) buffered solution of primary mouse monoclonal anti-MDM2 antibody (Ab-5, Calbiochem, used at a 1/10000 or 1/200 dilution depending on the antibody stock solution used), then washed three times with TBS-Tween before incubation for 45 mins at 20 °C with a TBS-Tween buffered solution of a goat-anti-mouse horseradish peroxidase (HRP) conjugated secondary antibody (used at 1/20000 or 1/2000 depending on the antibody stock solution). The unbound secondary antibody was removed by washing three times with TBS-Tween. The bound HRP activity was measured by enhanced chemiluminesence (ECL , Amersham Biosciences) using the oxidation of the diacylhydrazide substrate, luminol, to generate a quantifiable light signal. The percentage of MDM2 inhibition at a given concentration is calculated as the [1 - (RLU detected in the compound treated sample - RLU negative DMSO control) ÷ (RLU of DMSO positive and negative controls)] x 100 or as the (RLU detected in the compound treated sample ÷ RLU of DMSO controls) x 100. The IC50 was calculated using a plot of % MDM2 inhibition vs concentration and is the average of two or three independent experiments.

Western blot analysis



[1321] SJSA cells were treated for 6 hours with 5, 10 and 20 µM of compounds in 0.5% DMSO. The cells together with 0.5% DMSO only controls were washed with ice-cold phosphate buffered saline (PBS) and protein extracts prepared by lysing the cells in SDS buffer (62.5mM Tris pH 6.8; 2% sodium dodecyl sulphate(SDS); 10% glycerol) with sonication for 2x5seconds (Soniprep 150ME) to break down high molecular weight DNA and reduce the viscosity of the samples. The protein concentration of the samples was estimated using the Pierce BCA assay system (Pierce, Rockford, IL) and 50µg aliquots of protein analysed using standard SDS-polyacrylamide gel electrophoresis (SDS-PAGE) and Western immunoblotting procedures. β-mercaptoethanol (5%) and bromophenol blue (0.05%) were added and the samples, which were then boiled for 5 minutes, followed by brief centrifugation, before loading onto a pre-cast 4-20% gradient Tris-Glycine buffered SDS-polyacrylamide gel (Invitrogen). Molecular weight standards (SeeBlue, Invitrogen) were included on every gel and electrophoresis was carried out in a Novex XL tank (Invitrogen) at 180 volts for 90 minutes. The separated proteins were transferred electrophoretically overnight from the gel onto a Hybond C nitrocellulose membrane (Amersham) using a BioRad electrophoresis tank and 25mM Tris, 190mM glycine and 20% methanol transfer buffer at 30 volts or two hours at 70 volts. Primary antibodies used for immunodetection of the transferred proteins were: mouse monoclonal NCL-p53DO-7 (Novocastra) at 1:1000; MDM2(Ab-1, clone IF2) (Oncogene) at 1:500; WAF1 (Ab-1, clone 4D10) (Oncogene) at 1:100; Actin (AC40) (Sigma) at 1:1000. The secondary antibody used was peroxidase conjugated, affinity purified, goat anti-mouse (Dako) at 1:1000. Protein detection and visualisation was performed by enhanced chemiluminescence (ECL, Amersham) with light detection by exposure to blue-sensitive autoradiography film (Super RX, Fuji).

Protocol A: SJSA-1 and SN40R2 assays



[1322] The MDM2 amplified cell lines tested were an isogenic matched pair of p53 wild-type and mutated osteosarcoma (SJSA-1 and SN40R2, respectively). All cell cultures were grown in RPMI 1640 medium (Gibco, Paisley, UK) supplemented with 10% fetal calf serum and routinely tested and confirmed negative for mycoplasma infection. The growth of cells and its inhibition was measured using the sulphorhodamine B (SRB) method as previously outlined. 100 µl of 3×104/ml and 2×104/ml SJSA-1 and SN40R2 cells, respectively, were seeded into 96-well tissue culture plates and incubated at 37 °C in a 5% CO2 humidified incubator for 24hrs, after which the medium was replaced with 100 µl of test medium containing a range of MDM2-p53 antagonist concentrations and incubated for a further 72 hrs to allow cell growth before adding 25 µL of 50% trichloroacetic acid (TCA) to fix the cells for 1 h at 4 °C. The TCA was washed off with distilled water and 100 µL of SRB dye (0.4% w/v in 1% acetic acid) (Sigma-Aldrich, Poole, Dorset) added to each well of the plate. Following incubation with the SRB dye at room temperature for 30 min, the plates were washed with 1% acetic acid and left to dry. The SRB stained protein, which is a measure of the number of cells in a well, was then resuspended in 100 µL of 10 mM Tris-HCI (pH 10.5) and the absorbance at λ = 570 nm measured in each well using a FluoStar Omega Plate reader. The Gl50 was calculated by non-linear regression analysis of the data using Prism v4.0 statistical software.

Protocol B: SJSA-1 and SN40R2 assays



[1323] The CellTiter-Glo® Luminescent Cell Viability Assay is a homogeneous method to determine the number of viable cells in culture based on quantitation of the ATP present, which signals the presence of metabolically active cells. Both SJSA-1 and SN40R2 were grown in RPMI 1640 (Life Technologies #61870) supplemented with 10% FBS (PAA #A15-204) and 10 U/ml penicillin/streptomycin. 2000 cells in 75 µl were seeded in each well of a 96 well plate and left at 37 °C in a 5% CO2 humidified incubator for 24hrs. A range of MDM2-p53 antagonist concentrations in DMSO was then added to the cells to a final DMSO concentration of 0.3%, and incubated for a further 72 hrs to allow cell growth. 100 µl of CTG reagent (Promega #G7573) was added to all wells and luminescence was measured on the topcount. The EC50 values were determined from a sigmoidal 4 parameter curve fit using XLfit in conjunction with Activity Base (IDBS; Guildford, Surrey, UK).

Anti-proliferative Activity



[1324] Inhibition of cell growth is measured using the Alamar Blue assay (Nociari, M. M, Shalev, A., Benias, P., Russo, C. Journal of Immunological Methods 1998, 213, 157-167). The method is based on the ability of viable cells to reduce resazurin to its fluorescent product resorufin. For each proliferation assay cells are plated onto 96 well plates and allowed to recover for 16 hours prior to the addition of inhibitor compounds (in 0.1% DMSO v/v) for a further 72 hours. At the end of the incubation period 10% (v/v) Alamar Blue is added and incubated for a further 6 hours prior to determination of fluorescent product at 535nM ex / 590nM em. The anti-proliferative activities of compounds of the invention can be determined by measuring the ability of the compounds to inhibit growth in cancer cell lines for example as available from DSMZ , ECACC or ATCC.

[1326] Where more than one data point has been obtained, the table above shows an average (e.g. geometric or arithmetic mean) of these data points.

[1327] It is of course to be understood that the invention is not intended to be restricted to the details of the above embodiments which are described by way of example only.

Combination Protocol for Cell Proliferation



[1328] The effect of a compound of formula (I) (Compound 1) in combination with an anticancer agent (Compound II) can be assessed using the following technique. Cells from human cells lines (e.g.SJSA-1) were seeded onto 96-well tissue culture plates at a concentration of 2.5×103, 6.0 x103, or 4.0 ×103 cells/well respectively. Cells were allowed to recover for 24-48 hours prior to addition of compound(s) or vehicle control (0.35-0.5% DMSO) as follows:
Compounds were added concurrent for 72-96 hours. Following a total of 72-96 hours compound incubation, cells were fixed with ice-cold 10% (w/v) trichloroacetic acid for 1 hour on ice and then washed four times with dH20 using a plate washer (Labsystems Wellwash Ascent) and air-dried. Cells were then stained with 0.4% (w/v) Sulforhodamine B (Sigma) in 1% acetic acid for 20 min at room temperature and then washed four times with 1% (v/v) acetic acid and air-dried before the addition of 10mM Tris buffer to solubilise the dye. Colourmetric product was quantified by reading at Abs490nm or Abs570nm on a Wallac Victor2 plate reader (1420 multilabel counter, Perkin Elmer Life Sciences). The IC50 for Compound II in the presence of varying doses of Compound I was determined. Synergy was determined when the IC50 shifted down in the presence of sub-effective doses of Compound I. Additivity was determined when the response to Compound II and Compound I together resulted in an effect equivalent to the sum of the two compounds individually. Antagonistic effects were defined as those causing the IC50 to shift upwards, i.e. those where the response to the two compounds was less than the sum of the effect of the two compounds individually.

PHARMACEUTICAL FORMULATIONS EXAMPLES


(i) Tablet Formulation



[1329] A tablet composition containing a compound of the formula (I) is prepared by mixing an appropriate amount of the compound (for example 50-250 mg) with an appropriate diluent, disintegrant, compression agent and/or glidant. One possible tablet comprises 50 mg of the compound with 197 mg of lactose (BP) as diluent, and 3 mg magnesium stearate as a lubricant and compressing to form a tablet in known manner. The compressed tablet may be optionally film coated.

(ii) Capsule Formulation



[1330] A capsule formulation is prepared by mixing 100-250 mg of a compound of the formula (I) with an equivalent amount of lactose and filling the resulting mixture into standard hard gelatin capsules. An appropriate disintegrant and/or glidant can be included in appropriate amounts as required.

(iii) Injectable Formulation I



[1331] A parenteral composition for administration by injection can be prepared by dissolving a compound of the formula (I) (e.g. in a salt form) in water containing 10% propylene glycol to give a concentration of active compound of 1.5 % by weight. The solution is then made isotonic, sterilised by filtration or by terminal sterilisation, filled into an ampoule or vial or pre-filled syringe, and sealed.

(iv) Injectable Formulation II



[1332] A parenteral composition for injection is prepared by dissolving in water a compound of the formula (I) (e.g. in salt form) (2 mg/ml) and mannitol (50 mg/ml), sterile filtering the solution or by terminal sterilisation, and filling into sealable 1 ml vials or ampoules or pre-filled syringe.

(v) Injectable formulation III



[1333] A formulation for i.v. delivery by injection or infusion can be prepared by dissolving the compound of formula (I) (e.g. in a salt form) in water at 20 mg/ml and then adjusted for isotonicity. The vial is then sealed and sterilised by autoclaving or filled into an ampoule or vial or pre-filled syringe, sterilised by filtration and sealed.

(vi) Injectable formulation IV



[1334] A formulation for i.v. delivery by injection or infusion can be prepared by dissolving the compound of formula (I) (e.g. in a salt form) in water containing a buffer (e.g. 0.2 M acetate pH 4.6) at 20mg/ml. The vial, ampoule or pre-filled syringe is then sealed and sterilised by autoclaving or sterilized by filtration and sealed.

(vii) Subcutaneous or Intramuscular Injection Formulation



[1335] A composition for sub-cutaneous or intramuscular administration is prepared by mixing a compound of the formula (I) with pharmaceutical grade corn oil to give a concentration of 5-50 mg/ml. The composition is sterilised and filled into a suitable container.

(viii) Lyophilised formulation I



[1336] Aliquots of formulated compound of formula (I) are put into 50 ml vials and lyophilized. During lyophilisation, the compositions are frozen using a one-step freezing protocol at (-45 °C). The temperature is raised to -10 °C for annealing, then lowered to freezing at -45 °C, followed by primary drying at +25 °C for approximately 3400 minutes, followed by a secondary drying with increased steps if temperature to 50 °C. The pressure during primary and secondary drying is set at 80 millitor.

(ix) Lyophilised formulation II



[1337] Aliquots of formulated compound of formula (I) or a salt thereof as defined herein are put into 50 mL vials and lyophilized. During lyophilisation, the compositions are frozen using a one-step freezing protocol at (-45 °C). The temperature is raised to -10 °C for annealing, then lowered to freezing at -45 °C, followed by primary drying at +25 °C for approximately 3400 minutes, followed by a secondary drying with increased steps if temperature to 50 °C. The pressure during primary and secondary drying is set at 80 millitor.

(x) Lyophilised Formulation for use in i.v. administration III



[1338] An aqueous buffered solution is prepared by dissolving a compound of formula I in a buffer. The buffered solution is filled, with filtration to remove particulate matter, into a container (such as a Type 1 glass vial) which is then partially sealed (e.g. by means of a Fluorotec stopper). If the compound and formulation are sufficiently stable, the formulation is sterilised by autoclaving at 121°C for a suitable period of time. If the formulation is not stable to autoclaving, it can be sterilised using a suitable filter and filled under sterile conditions into sterile vials. The solution is freeze dried using a suitable cycle. On completion of the freeze drying cycle the vials are back filled with nitrogen to atmospheric pressure, stoppered and secured (e.g. with an aluminium crimp). For intravenous administration, the freeze dried solid can be reconstituted with a pharmaceutically acceptable diluent, such as 0.9% saline or 5% dextrose. The solution can be dosed as is, or can be diluted further into an infusion bag (containing a pharmaceutically acceptable diluent, such as 0.9% saline or 5% dextrose), before administration.

(xii) Powder in a bottle



[1339] A composition for oral administration is prepared by filling a bottle or vial with a compound of the formula (I). The composition is then reconstituted with a suitable diluent for example water, fruit juice, or commercially available vehicle such as OraSweet or Syrspend. The reconstituted solution may be dispensed into dosing cups or oral syringes for administration.
