Description


[0001] The present invention relates to certain 4-substituted 1H-pyrrolo[2,3-b]pyridine compounds of the formula (I) and pharmaceutically acceptable salts thereof. These compounds is useful in the treatment or prevention of a disease or medical condition mediated through certain mutated forms of ErbB receptor, especially of Exon20 Her2 and EGFR mutations.

Field of the Invention



[0002] The present invention relates to certain 4-substituted 1H-pyrrolo[2,3-b]pyridine compounds of the formula (I) and pharmaceutically acceptable salts thereof. These compounds is useful in the treatment or prevention of a disease or medical condition mediated through certain mutated forms of ErbB receptor, especially of Exon20 Her2 and EGFR mutations.


Background of the Invention



[0003] Receptor tyrosine kinases (RTKs) are cell surface receptors that transmit signals from the extracellular environment to control growth, differentiation and survival of cells. Deregulated expression of protein kinases by gene deletion, - mutation or -amplification has been found to be important for tumor initiation and -progression, involving cancer cell proliferation, -survival, -motility and - invasivity as well tumor angiogenesis and chemotherapy resistance. Because of the advanced understanding of their critical role, protein kinases are important targets for novel therapies, especially for cancer (Hananhan et al. Cell 2000, 7, 100(1): 57-70; Blume-Jensen et al., Nature 2001, 17, 411(6835): 355-65).

[0004] In humans the receptor tyrosine kinase family ErbB comprises four members: EGFR (Her1), ErbB2 (Her2), ErbB3 (Her3) and ErbB4 (Her4). The binding of a ligand induces conformational change in receptors to form homo- and heterodimerization. The extracellular domain of Her2 is already fixed in a conformation without ligand binding that resembles the other ligand-activated ErbB members and hereby acts as a preferred dimerization partner for other ligand-bound ErbBs. The dimerization of receptors activates the intrinsic kinase activity and hereby yielding to the phosphorylation of its substrates, resulting in activation of multiple downstream pathways within the cell, including the anti-apoptotic/survival PI3K-AKT-mTOR and the mitogenic RAS-RAF-MEK-ERK-MAPK pathways (Chong et al. Nature Med. 2013; 19 (11):1389-1400).

[0005] There is strong precedent for the involvement of ErbB kinase family in human cancer as overexpression and/or mutations of ErbB is commonly found in cancers (for example breast, lung, head, neck and bladder). First generation small molecule EGFR inhibitors like Tarceva (Erlotinib) and Iressa (Gefitinib), both binding reversibly to EGFR, are currently first-line therapy for non-small cell lung cancer patients with tumors harbouring EGFR mutations in exon 19 and 21 (like L858R and delE746-A750). Second and third generation small molecule EGFR inhibitors have been designed as irreversible EGFR inhibitors. These compounds (for example Afatinib, HKI-272, CI-1033, EKB-569, WZ-4002, AZ9291, CO-1686) bind irreversibly to EGFR, preferably to cysteine 773.

[0006] Approximately 10% of patients with NSCLC in the United States are reported to have tumor-associated EGFR mutations (Lynch et al. N Engl J Med. 2004, 350 (21): 2129-39). The EGFR mutations mostly occur within EGFR Exon 18-21 (Yasuda et al. Sci Transl Med. 2013, 18, 5(216): 216ra177; Leduc et al. Annals of Oncology 2017, 28, 11: 2715-2724; Arcila et al. Mol Cancer Ther. 2013, 12 (2): 220-229). These mutations increase the kinase activity of EGFR, leading to hyperactivation of downstream pro-survival signalling pathways (Pao et al. Nat Rev Cancer 2010, 10: 760-774). EGFR Exon 20 insertions reportedly comprise approximately 4-9.2 % of all EGFR mutant lung tumors (Arcila et al. Mol Cancer Ther. 2013, 12 (2): 220-9; Oxnard et al. J Thorac Oncol. 2013, 8(2): 179-184; Yasuda et al. Lancet Oncol. 2012, 13 (1): e23-31). Most EGFR Exon 20 insertions occur in the region encoding amino acids 767 through 774 of exon 20 within the loop that follows the C-helix of the kinase donmain of EGFR. Analysis of patients with tumors harbouring EGFR Exon 20 insertion mutations mostly displayed progressive disease in the course of treatment with Gefitinib, Erlotinib or Afatinib (Yasuda et al. Lancet Oncol. 2012, 13 (1): e23-31; Yasuda et al. Sci Transl Med. 2013, 18, 5(216): 216ra177).

[0007] Her2 mutations are reportedly present in ∼2-4% of NSCLC (Buttitta et al. Int J Cancer. 2006, 119: 2586-2591). The most common mutation is an in-frame insertion within Exon 20. In 83% of patients having Her2 associated NSCLC, a four amino acid YVMA insertion mutation occurs at codon 775 in Exon 20 of Her2 (Arcila et al. Clin Cancer Res 2012, 18: 4910-4918). The Her2 Exon 20 insertion results in increased kinase activity and enhanced signalling through downstream pathways, resulting in increased survival, invasiveness, and tumorgenicity (Wang et al. Cancer Cell 2006; 10: 25-38). Tumors harbouring the Her2 YVMA mutation are largely resistant to known EGFR inhibitors (Arcila et al. Clin Cancer Res 2012, 18: 4910-4918).

[0008] It is object of the present invention to provide compounds as mutant-selective ErbB inhibitors, especially for the Exon 20 EGFR/Her2 mutations, and/or pharmaceutically acceptable salts thereof which can be used as pharmaceutically active agents, and use thereof especially for prophylaxis and/ or treatment of cell proliferative disease, especially cancer, a combination comprising the inventive compound and at least one anticancer drug; as well as compositions comprising at least one of those compounds and/or pharmaceutically acceptable salts thereof as pharmaceutically active ingredients

[0009] The present invention provides novel compound(s) being mutant-selective ErbB inhibitors, especially for the Exon 20 EGFR/Her2 mutations, and additionally being inhibitors for other mutants like EGFR T790ML858R mutation.

[0010] The objective of the present invention is solved by the teaching of the independent claims. Further advantageous features, aspects and details of the invention are evident from the dependent claims, the description, the figures, and the examples of the present application.

or an enantiomer, a mixture of enantiomers, a diastereomer, a mixture of diastereomers, a tautomer, a prodrug, a hydrate, a solvate of the above mentioned compounds, or pharmaceutically acceptable salts thereof.

[0031] The expression prodrug is defined as a substance, which is applied in an inactive or significantly less active form. Once applied and incorporated, the prodrug is metabolized in the body in vivo into the active compound. Conventional procedures for the selection and preparation of suitable prodrug derivatives are described, for example in "Design of Prodrugs", ed. H. B. Bundgaard, Elsevier, 1985.

[0032] The present invention also includes within its scope N-oxides of the compounds of formula (I) above. In general, such N-oxides may be formed by conventional means, such as reacting the compound of formula (I) with oxone in the presence of wet alumina.

[0033] The expression tautomer is defined as an organic compound that is interconvertible by a chemical reaction called tautomerization. Tautomerization can be catalyzed preferably by bases or acids or other suitable compounds.

[0034] The compounds of the present invention may form salts with organic or inorganic acids or bases. Examples of suitable acids for such acid addition salt formation are hydrochloric acid, hydrobromic acid, sulfuric acid, phosphoric acid, acetic acid, citric acid, oxalic acid, malonic acid, salicylic acid, p-aminosalicylic acid, malic acid, fumaric acid, succinic acid, ascorbic acid, maleic acid, sulfonic acid, phosphonic acid, perchloric acid, nitric acid, formic acid, propionic acid, gluconic acid, lactic acid, tartaric acid, hydroxymaleic acid, pyruvic acid, phenylacetic acid, benzoic acid, p-aminobenzoic acid, p-hydroxybenzoic acid, methanesulfonic acid, ethanesulfonic acid, nitrous acid, hydroxyethanesulfonic acid, ethylenesulfonic acid, p-toluenesulfonic acid, naphthylsulfonic acid, sulfanilic acid, camphorsulfonic acid, china acid, mandelic acid, o-methylmandelic acid, hydrogen-benzenesulfonic acid, picric acid, adipic acid, D-o-tolyltartaric acid, tartronic acid, (o, m, p)-toluic acid, naphthylamine sulfonic acid, trifluoroacetic acid, and other mineral or carboxylic acids well known to those skilled in the art. The salts are prepared by contacting the free base form of the compounds of formula (I) with a sufficient amount of the desired acid to produce a salt in the conventional manner well known to those skilled in the art.

[0035] The inventive compounds may exist in a number of different polymorphic forms.

[0036] In the case the inventive compounds bear acidic groups, salts could also be formed with inorganic or organic bases. Examples for suitable inorganic or organic bases are, for example, NaOH, KOH, NH4OH, tetraalkylammonium hydroxide, lysine or arginine and the like. Salts may be prepared in a conventional manner using methods well known in the art, for example by treatment of a solution of the compound of the general formula (I) with a solution of an acid, selected out of the group mentioned above.

[0037] The inventors found that in order to obtain inhibitors which exhibit metabolic stability against liver microsomes the 2-position at the phenyl ring next to the warhead must be substituted. The warhead can be a but-2-enamide, 4-(dimethylamino)but-2-enamide, propiolamide, ethenesulfonamide, acrylamide, or 2-chloro-acetamide residue. The position 2 on the phenyl ring next to the warhead must be different from hydrogen and is preferably an alkyl or alkylenyl residue such as a methyl group (like in compounds No. 1 - 54, 72 - 82, 116 - 148) or can be part of a ring system preferably containing the nitrogen atom of the warhead (like in compounds No. 55 - 71, 83 - 95, 98 - 115). Without this substituent and especially without this -CH3 or -CH2- substituent, no metabolic stability against liver microsomes can be achieved and consequently no pharmaceutical activity can be obtained in vivo.

Pharmaceutical Composition



[0075] The pharmaceutical compositions according to the present invention comprise at least one compound according to the present invention as an active ingredient together with at least one pharmaceutically acceptable (i.e. non-toxic) carrier, excipient and/or diluent. The pharmaceutical compositions of the present invention can be prepared in a conventional solid or liquid carrier or diluent and a conventional pharmaceutically made adjuvant at suitable dosage level in a known way. The preferred preparations are adapted for oral application. These administration forms include, for example, pills, tablets, film tablets, coated tablets, capsules, powders and deposits.

[0076] Optionally, the pharmaceutical compositions according to the present invention comprise further at least one anticancer drug. The at least one anticancer is anticancer drug inhibting EGFR/HER2 tyrosine kinases, anticancer drug targeting the RAS/RAF/MEK/ERK signal pathway, anticancer drug targeting PI3K/AKT/mTOR signal pathway, and/or anticancer drug targeting JAK/STAT signal pathway as defined above.

[0077] Furthermore, the present invention also includes pharmaceutical preparations for parenteral application, including dermal, intradermal, intragastral, intracutaneous, intravasal, intravenous, intramuscular, intraperitoneal, intranasal, intravaginal, intrabuccal, percutan, rectal, subcutaneous, sublingual, topical, or transdermal application, which preparations in addition to typical vehicles and/or diluents contain at least one compound according to the present invention and/or a pharmaceutical acceptable salt thereof as active ingredient.

[0078] The pharmaceutical compositions according to the present invention containing at least one compound according to the present invention and/or a pharmaceutical acceptable salt thereof as active ingredient will typically be administered together with suitable carrier materials selected with respect to the intended form of administration, i.e. for oral administration in the form of tablets, capsules (either solid filled, semi-solid filled or liquid filled), powders for constitution, gels, elixirs, dispersable granules, syrups, suspensions, and the like, and consistent with conventional pharmaceutical practices. For example, for oral administration in the form of tablets or capsules, the active drug component may be combined with any oral non-toxic pharmaceutically acceptable carrier, preferably with an inert carrier like lactose, starch, sucrose, cellulose, magnesium stearate, dicalcium phosphate, calcium sulfate, talc, mannitol, ethyl alcohol (liquid filled capsules) and the like. Moreover, suitable binders, lubricants, disintegrating agents and coloring agents may also be incorporated into the tablet or capsule. Powders and tablets may contain about 5 to about 95-weight % of the derivatives according to the general formula (I) or analogues compound thereof or the respective pharmaceutically active salt as active ingredient.

[0079] Suitable binders include starch, gelatin, natural sugars, corn sweeteners, natural and synthetic gums such as acacia, sodium alginate, carboxymethylcellulose, polyethylene glycol and waxes. Among suitable lubricants there may be mentioned boric acid, sodium benzoate, sodium acetate, sodium chloride, and the like. Suitable disintegrants include starch, methylcellulose, guar gum, and the like. Sweetening and flavoring agents as well as preservatives may also be included, where appropriate. The disintegrants, diluents, lubricants, binders etc. are discussed in more detail below.

[0080] Moreover, the pharmaceutical compositions of the present invention may be formulated in sustained release form to provide the rate controlled release of any one or more of the components or active ingredients to optimise the therapeutic effect(s), e.g. anti-cancer activity or activity against cancer metastases and the like. Suitable dosage forms for sustained release include tablets having layers of varying disintegration rates or controlled release, polymeric matrices impregnated with the active components and shaped in tablet form or capsules containing such impregnated or encapsulated porous polymeric matrices.

[0081] Liquid form preparations include solutions, suspensions, and emulsions. As an example, there may be mentioned water or water/propylene glycol solutions for parenteral injections or addition of sweeteners and opacifiers for oral solutions, suspensions, and emulsions. Liquid form preparations may also include solutions for intranasal administration.

[0082] Aerosol preparations suitable for inhalation may include solutions and solids in powder form, which may be present in combination with a pharmaceutically acceptable carrier such as an inert, compressed gas, e.g. nitrogen.

[0083] For preparing suppositories, a low melting wax, such as a mixture of fatty acid glycerides like cocoa butter is melted first, and the active ingredient is then dispersed homogeneously therein e.g. by stirring. The molten, homogeneous mixture is then poured into conveniently sized moulds, allowed to cool, and thereby solidified.

[0084] Also included are solid form preparations, which are intended to be converted, shortly before use, to liquid form preparations for either oral or parenteral administration. Such liquid forms include solutions, suspensions, and emulsions.

[0085] The compounds according to the present invention may also be delivered transdermally. The transdermal compositions may have the form of a cream, a lotion, an aerosol and/or an emulsion and may be included in a transdermal patch of the matrix or reservoir type as is known in the art for this purpose.

[0086] The term capsule as recited herein refers to a specific container or enclosure made e.g. of methylcellulose, polyvinyl alcohols, or denatured gelatins or starch for holding or containing compositions comprising the active ingredient(s). Capsules with hard shells are typically made of blended of relatively high gel strength gelatins from bones or pork skin. The capsule itself may contain small amounts of dyes, opaquing agents, plasticisers and/or preservatives.

[0087] Under tablet a compressed or moulded solid dosage form is understood which comprises the active ingredients with suitable diluents. The tablet may be prepared by compression of mixtures or granulations obtained by wet granulation, dry granulation, or by compaction well known to a person of ordinary skill in the art.

[0088] Oral gels refer to the active ingredients dispersed or solubilised in a hydrophilic semi-solid matrix.

[0089] Powders for constitution refers to powder blends containing the active ingredients and suitable diluents which can be suspended e.g. in water or in juice.

[0090] Suitable diluents are substances that usually make up the major portion of the composition or dosage form. Suitable diluents include sugars such as lactose, sucrose, mannitol, and sorbitol, starches derived from wheat, corn, rice, and potato, and celluloses such as microcrystalline cellulose. The amount of diluent in the composition can range from about 5 to about 95 % by weight of the total composition, preferably from about 25 to about 75 weight %, and more preferably from about 30 to about 60 weight %.

[0091] The term disintegrants refers to materials added to the composition to support break apart (disintegrate) and release the pharmaceutically active ingredients of a medicament. Suitable disintegrants include starches, "cold water soluble" modified starches such as sodium carboxymethyl starch, natural and synthetic gums such as locust bean, karaya, guar, tragacanth and agar, cellulose derivatives such as methylcellulose and sodium carboxymethylcellulose, microcrystalline celluloses, and cross-linked microcrystalline celluloses such as sodium croscaramellose, alginates such as alginic acid and sodium alginate, clays such as bentonites, and effervescent mixtures. The amount of disintegrant in the composition may range from about 2 to about 20 weight % of the composition, more preferably from about 5 to about 10 weight %.

[0092] Binders are substances which bind or "glue" together powder particles and make them cohesive by forming granules, thus serving as the "adhesive" in the formulation. Binders add cohesive strength already available in the diluent or bulking agent. Suitable binders include sugars such as sucrose, starches derived from wheat, corn, rice and potato, natural gums such as acacia, gelatin and tragacanth, derivatives of seaweed such as alginic acid, sodium alginate and ammonium calcium alginate, cellulose materials such as methylcellulose, sodium carboxymethylcellulose and hydroxypropylmethylcellulose, polyvinylpyrrolidone, and inorganic compounds such as magnesium aluminum silicate. The amount of binder in the composition may range from about 2 to about 20 weight % of the composition, preferably from about 3 to about 10 weight %, and more preferably from about 3 to about 6 weight %.

[0093] Lubricants refer to a class of substances which are added to the dosage form to enable the tablet granules etc. after being compressed to release from the mould by reducing friction or wear. Suitable lubricants include metallic stearates such as magnesium stearate, calcium stearate, or potassium stearate, stearic acid, high melting point waxes, and other water soluble lubricants such as sodium chloride, sodium benzoate, sodium acetate, sodium oleate, polyethylene glycols and D,L-leucine. Lubricants are usually added at the very last step before compression, since they must be present at the surface of the granules. The amount of lubricant in the composition may range from about 0.2 to about 5 weight % of the composition, preferably from about 0.5 to about 2 weight %, and more preferably from about 0.3 to about 1.5 weight % of the composition.

[0094] Glidents are materials that prevent caking of the components of the pharmaceutical composition and improve the flow characteristics of granulate so that flow is smooth and uniform. Suitable glidents include silicon dioxide and talc. The amount of glident in the composition may range from about 0.1 to about 5 weight % of the final composition, preferably from about 0.5 to about 2 weight %.

[0095] Coloring agents are excipients that provide coloration to the composition or the dosage form. Such excipients can include food grade dyes adsorbed onto a suitable adsorbent such as clay or aluminum oxide. The amount of the coloring agent may vary from about 0.1 to about 5 weight % of the composition, preferably from about 0.1 to about 1 weight %.

[0096] The compounds of the present invention are suitable for use in medicine, particulary in human medicine, but also in veterinary medicine. The dosage of the compounds may be determined by a skilled practitioner according to the type and severity of the disorder to be treated.

[0097] The compounds of the present invention may be admistered as a monotherapy or together with further active agents, particulary chemotherapeutic agents or antitumor antibodies. Furthermore they may be used in combination with surgery and/or irradiation.

Biological Assays



[0257] The exemplified compounds described herein were tested for activity and were found to have an IC50 value less than 10uM, particularly less than 500nM, in one of the following assays:

1. Measurement of HER2 INS YVMA kinase activity



[0258] This protocol describes how the Lance Kinase Activity Assay was performed to determine IC50 values of compounds of general formula (I) against HER2 INS YVMA. The principle behind this enzymatic assay is based upon the phosphorylation of the Ulight-peptide substrate. It is detected by using a specific EU-labeled anti-phospho peptide antibody. The binding of the Eu labeled anti-phospho peptide antibody to the phosphorylated ULight labeled peptide gives rise to a FRET-signal.

[0259] Binding of an inhibitor to the kinase prevents phosphorylation of the Ulight-substrate, resulting in a loss of FRET. In table 2 is summarized the relevant information for the LANCE assay.
Table 2: Reagents, stock concentrations and final assay concentrations for Her2 INS YVMA.

Her2 ins YVMA 41,83 µM 2,5 nM 1 nM DPF
ATP 100 mM 8 µM 1,6 µM Sigma


[0260] The compounds of general formula (I) summarized in Table 3 were serial diluted from a 10 mM DMSO stock solution 1:3 over 8 steps in a total volume of 20 µl.
For every sample, 8 µl of kinase-substrate mix was transferred into a suitable assay plate (e.g. Corning #3673). Compound was added via pintool transfer (10nl/well) using a Biomek FX robot (BeckmanCoulter). Reaction was started by addition of 2µl ATP working solution and mixed using variomag teleshaker (Thermo Fischer Scientific). After 1 h incubation at room temperature the reaction was stopped with 10µl detection mix containing the Eu-labeled phosphospecific antibody and 10mM EDTA. After a second incubation period of 1 h at room temperature the FRET signal was measured at 340 nm excitation, 665 nm and 615 nm emission (for the ULight-substrate and Eu-AB, respectively) with an Envision spectrophotometer (Perkin Elmer, Waltham, MA, USA) with 50 µs delay and 300 µs integration time. IC50 values were determined from the sigmoidal dose response curves with the software Quattro Workflow (Quattro GmbH, Munich, Germany).

2. Measurement of cellular activity



[0261] The CellTiter-Glo Luminescent Cell Viability Assay (Promega) is a homogeneous method of determining the number of viable cells in culture. It is based on quantification of ATP, indicating the presence of metabolically active cells. Cells are seeded on day 1 at cell numbers that assure assay linearity and optimal signal intensity. After incubation for 24h in humidified chambers at 37°C and 5% CO2, compounds in DMSO are added at different concentrations. Cells are further incubated for 72 h at 37°C and 5% CO2. Cells treated with the compound vehicle DMSO are used as positive controls and cells treated with 10 µM Staurosporine serve as negative controls. At day 5 the CellTiter Glo Reagent is prepared according to the instructions of the kit (Promega Inc.): Reagent is mixed 1:1 with cell culture medium. Thereon, mixture and assay plates are equilibrated at room temperature for 20 min. Equal volumes of the reagent-medium-mixture is added to the volume of culture medium present in each well. The plates are mixed at ∼200 rpm for 2 minutes on an orbital shaker. The microplates are then incubated at room temperature for 10 minutes for stabilization of the luminescent signal. Following incubation the luminescence is recorded on a Victor microplate reader (Perkin Elmer) using a 200 ms integration time. The data is then analyzed with Excel using the XLFIT Plugin (dose response Fit 205) for IC50-determination. As quality control the Z'-factor is calculated from 16 positive and negative control values. Only assay results showing a Z'-factor ≥ 0.5 are used for further analysis.

3. Metabolic stability



[0264] There are two major groups of enzyme reactions catalyzed by drug metabolizing enzymes, the so called Phase I and Phase II reactions. The basic processes in phase I reactions are oxidation, reduction and/or hydrolysis mostly catalyzed by the cytochrome P450 (CYP) family of enzymes. Exploring the metabolic stability of reference 1 we have observed as a major metabolite the hydrolysis of the acrylamide moiety in the presence of mouse liver microsomes with and without the cofactor NADPH. Figure 2 shows the hydrolysis of the acrylamide moiety of reference 1 in the presence of mouse liver microsomes after 50 minutes.

[0265] The following procedures describe the determination of the in vitro Phase I metabolic stability of test compounds using liver microsomes by measuring compound depletion over time. Test compound at the concentration of 3 µM was incubated with the liver microsomes from the mouse species and the experiment was performed without NADPH. The depletion of the test compounds was measured over time up to 50 minutes at 37 °C by LC-MS/MS. Different compounds were tested under these conditions for microsomal stability (see Table 5). Prevention of hydrolysis of the acrylamide moiety was achieved either by the introduction of substituents like a methyl group (as in Example 1) next to the acrylamide moiety or by modifying the secondary acrylamide of reference 1 to a tertiary acrylamide (like Example 55).
