Description

FIELD OF THE INVENTION

[0001] The invention relates to pyrimidine compounds, compositions comprising such a compound, and methods of synthesizing such compounds. The invention relates to said compounds for use in treating PI3K-related diseases.

BACKGROUND OF THE INVENTION

[0002] Phosphatidylinositol (hereinafter abbreviated as "PI") is one of the phospholipids in cell membranes. In recent years it has become clear that PI plays an important role also in intracellular signal transduction. It is well recognized in the art that PI (4,5) bisphosphate (PI(4,5)P2 or PIP2) is degraded into diacylglycerol and inositol (1,4,5) triphosphate by phospholipase C to induce activation of protein kinase C and intracellular calcium mobilization, respectively [M. J. Berridge et al., Nature, 312, 315 (1984); Y. Nishizuka, Science, 225, 1365 (1984)].

[0003] In the late 1980s, phosphatidylinositol-3 kinase ("PI3K") was found to be an enzyme that phosphorylates the 3-position of the inositol ring of phosphatidylinositol [D. Whitman et al., Nature, 332, 664 (1988)]. When PI3K was discovered, it was originally considered to be a single enzyme. Recently however, it was clarified that a plurality of PI3K subtypes exists. Three major subtypes of PI3Ks have now been identified on the basis of their in vitro substrate specificity, and these three are designated class I (a & b), class II, and class III [B. Vanhaesebroeck, Trend in Biol. Sci., 22, 267(1997)].

[0004] The class la PI3K subtype has been most extensively investigated to date. Within the class la subtype there are three isoforms (α, β, & δ) that exist as hetero dimers of a catalytic 110-kDa subunit and regulatory subunits of 50-85kDa. The regulatory subunits contain SH2 domains that bind to phosphorylated tyrosine residues within growth factor receptors or adaptor molecules and thereby localize PI3K to the inner cell membrane. At the inner cell membrane PI3K converts PIP2 to PIP3 (phosphatidylinositol-3,4,5-trisphosphate) that serves to localize the downstream effectors PDK1 and Akt to the inner cell membrane where Akt activation occurs. Activated Akt mediates a diverse array of effects including inhibition of apoptosis, cell cycle progression, response to insulin signaling, and cell proliferation. Class la PI3K subtypes also contain Ras binding domains (RBD) that allow association with activated Ras providing another mechanism for PI3K membrane localization. Activated, oncogenic forms of growth factor receptors, Ras, and even PI3K kinase have been shown to aberrantly elevate signaling in the PI3K/Akt/mTOR pathway resulting in cell transformation. As a central component of the PI3K/Akt/mTOR signaling pathway PI3K (particularly the class la α isoform) has become a major therapeutic target in cancer drug discovery.

[0005] Substrates for class I PI3Ks are PI, PI(4)P and PI(4,5)P2, with PI(4,5)P2 being the most favored. Class I PI3Ks are further divided into two groups, class la and class Ib, because of their activation mechanism and associated regulatory subunits. The class Ib PI3K is p110γ that is activated by interaction with G protein-coupled receptors. Interaction between p110γ and G protein-coupled receptors is mediated by regulatory subunits of 110, 87, and 84 kDa.

[0006] PI and PI(4)P are the known substrates for class II PI3Ks; PI(4,5)P2 is not a substrate for the enzymes of this class. Class II PI3Ks include PI3K C2α, C2β and C2γ isoforms, which contain C2 domains at the C terminus, implying that their activity is regulated by calcium ions.

[0007] The substrate for class III PI3Ks is PI only. A mechanism for activation of the class III PI3Ks has not been clarified. Because each subtype has its own mechanism for regulating activity, it is likely that activation mechanism(s) depend on stimuli specific to each respective class of PI3K.

[0008] The compound PI103 (3-(4-(4-morpholinyl)pyrido[3',2':4,5]furo[3,2-d]pyrimidin-2-yl)phenol) inhibits PI3K_α and PI3K_γ as well as the mTOR complexes with IC₅₀ values of 2, 3, and 50-80 nM respectively. I.P. dosing in mice of this compound in human tumor xenograft models of cancer demonstrated activity against a number of human tumor models, including the glioblastoma (PTEN null U87MG), prostate (PC3), breast (MDA-MB-468 and MDA-MB-435) colon carcinoma (HCT 116); and ovarian carcinoma (SKOV3 and IGROV-1); (Raynaud et al, Pharmacologic Characterization of a Potent Inhibitor of Class I Phosphatidylinositide 3-Kinases, Cancer Res. 2007 67: 5840-5850).

[0009] The compound ZSTK474 (2-(2-difluoromethylbenzoimidazol-1-yl)-4,6-dimorpholino-1,3,5-triazine) inhibits PI3K_α and PI3K_γ but not the mTOR enzyme with IC₅₀ values of 16, 4.6 and >10,000 nM respectively (Dexin Kong and Takao Yamori, ZSTK474 is an ATP-competitive inhibitor of class I phosphatidylinositol 3 kinase isoforms, Cancer Science, 2007, 98:10 1638-1642). Chronic oral administration of ZSTK474 in mouse human xenograft cancer models completely inhibited growth that originated from a non-small-cell lung cancer (A549), a prostate cancer (PC-3), and a colon cancer (WiDr) at a dose of 400 mg/kg. (Yaguchi et al, Antitumor Activity of ZSTK474, a New Phosphatidylinositol 3-Kinase Inhibitor, J. Natl. Cancer Inst. 98: 545-556).

[0010] The compound NVP-BEZ-235 (2-methyl-2-(4-(3-methyl-2-oxo-8-(quinolin-3-yl)-2,3-dihydro-1H-imidazo[4,5-c]quinolin-1-yl)phenyl)propanenitrile) inhibits both PI3K_α and PI3K_γ as well as the mTOR enzyme with IC₅₀ values 4, 5, and "nanomolar". Testing in human tumor xenograft models of cancer demonstrated activity against human tumor models of prostrate (PC-3) and glioblastoma (U-87) cancer. It entered clinical trials in December of 2006

[0011] (Verheijen, J.C and Zask, A , Phosphatidylinositol 3-kinase (PI3K) inhibitors as anticancer drugs, Drugs Fut. 2007, 32(6) 537-547)

[0012] The compound SF-1126 (a prodrug form of LY-294002, which is 2-(4-morpholinyl)-8-phenyl-4H-1-benzopyran-4-one) is "a pan-PI3K inhibitor". It is active in preclinical mouse cancer models of prostrate, breast, ovarian, lung, multiple myeloma, and brain cancers It began clinical trials in April 2007 for the solid tumors endometrial, renal cell, breast, hormone refractory prostate and ovarian cancers (Verheijen, J.C and Zask, A., Phosphatidylinositol 3-kinase (PI3K) inhibitors as anticancer drugs, Drugs Fut. 2007, 32(6) 537-547). Published US patent application US 2009 / 0098086 discloses certain thienopyrimidine and pyrazolopyrimidine compounds and their MTOR kinase and PI3 kinase inhibitory activity.

[0013] Exelixis Inc (So San Francisco, CA) recently filed INDs for XL-147 (a selective pan-PI3K inhibitor of unknown structure) and XL-765 (a mixed inhibitor of mTOR and PI3K of unknown structure) as anticancer agents TargeGen's short-acting mixed inhibitor of PI3K_γ and δ, TG-100115, is in phase I/II trials for treatment of infarct following myocardial ischemia-reperfusion injury Cerylid's antithrombotic PI3Kβ inhibitor CBL-1309 (structure unknown) has completed preclinical toxicology studies.

[0014] According to Verheijen, J C. and Zask, A., Phosphatidylinositol 3-kinase (PI3K) inhibitors as anticancer drugs, Drugs Fut. 2007, 32(6): 537-547,

[0015] Although it seems clear that inhibition of the a isoform is essential for the antitumor activity of PI3K inhibitors, it is not clear whether a more selective inhibitor of a particular PI3K isoform may lead to fewer unwanted biological effects It has recently been reported that non-PI3Kα class I isoforms (PI3Kβ, δ and γ) have the ability to induce oncogenic transformation of cells, suggesting that nonisoform- specific inhibitors may offer enhanced therapeutic potential over specific inhibitors

[0016] Selectivity versus other related kinases is also an important consideration for the development of PI3K inhibitors. While selective inhibitors may be preferred in order to avoid unwanted side effects, there have been reports that inhibition of multiple targets in the PI3K/Akt pathway (e g , PI3Kα and mTOR [mammalian target of rapamycin]) may lead to greater efficacy. It is possible that lipid kinase inhibitors may parallel protein kinase inhibitors in that nonselective inhibitors may also be brought forward to the clinic.

[0017] Mammalian Target of Rapamycin, mTOR, is a cell-signaling protein that regulates the response of tumor cells to nutrients and growth factors, as well as controlling tumor blood supply through effects on Vascular Endothelial Growth Factor, VEGF. Inhibitors of mTOR starve cancer cells and shrink tumors by inhibiting the effect of mTOR. All mTOR inhibitors bind to the mTOR kinase This has at least two important effects. First, mTOR is a downstream mediator of the PI3K/Akt pathway. The PI3K/Akt pathway is thought to be over-activated in numerous cancers and may account for the widespread response from various cancers to mTOR inhibitors. The over-activation of the upstream pathway would normally cause mTOR kinase to be over-activated as well. However, in the presence of mTOR inhibitors, this process is blocked. The blocking effect prevents mTOR from signaling to downstream pathways that control cell growth. Over-activation of the PI3K/Akt kinase pathway is frequently associated with mutations in the PTEN gene, which is common in many cancers and may help predict what tumors will respond to mTOR inhibitors. The second major effect of mTOR inhibition is anti-angiogenesis, via the lowering of VEGF levels.

[0018] In lab tests, certain chemotherapy agents were found to be more effective in the presence of mTOR inhibitors. George, J.N., et al., Cancer Research, 61, 1527-1532, 2001. Additional lab results have shown that some rhabdomyosarcoma cells die in the presence of mTOR inhibitors. The complete functions of the mTOR kinase and the effects of mTOR inhibition are not completely understood.

[0019] There are three mTOR inhibitors, which have progressed into clinical trials. These compounds are Wyeth's Torisel, also known as 42-(3-hydroxy-2-(hydroxymethyl)-rapamycin 2-methylpropanoate, CCI-779 or Temsirolimus; Novartis' Everolimus, also known as 42-O-(2-hydroxyethyl)-rapamycin, or RAD 001; and Ariad's AP23573 also known as 42-(dimethylphopsinoyl)-rapamycin. The FDA has approved Torisel for the treatment of advanced renal cell carcinoma. In addition, Torisel is active in a NOS/SCID xenograft mouse model of acute lymphoblastic leukemia [Teachey et al, Blood, 107(3), 1149-1155, 2006]. On March 30, 2009, the U. S. Food and Drug Administration (FDA) approved Everolimus (AFINITOR™) for the treatment of patients with advanced renal cell carcinoma. AP23573 has been given orphan drug and fast-track status by the FDA for treatment of soft-tissue and bone sarcomas.

[0020] The three mTOR inhibitors have non-linear, although reproducible pharmacokinetic profiles. Mean area under the curve (AUC) values for these drugs increase at a less than dose related way. The three compounds are all semi-synthetic derivatives of the natural macrolide antibiotic rapamycin. It would be desirable to find fully synthetic compounds, which inhibit mTOR that are more potent and exhibit improved pharmacokinetic behaviors.

[0021] The most recently described PI3K family member was identified in human cells and named human SMG-1 or hSMG-1. Yamashita (Genes Dev. 2001 15: 2215-2228) characterized two isoforms of hSMG-1 proteins, p430 and p400, which are expressed in various cell lines of human, monkey, rat, and mouse. Yamashita's p400 hSMG-1 isoform is a 3529-amino-acid protein of 396,040 Daltons. Brumbaugh (Molecular Cell, Volume 14, Issue 5, 4 June 2004, Pages 585-598) isolated a 3521 amino acid polypeptide with a deduced molecular mass of 395 kDa. Brumbaugh's hSMG-1 is eight amino acids shorter at the amino terminus than the protein isolated by Yamashita.

[0022] Both hUpf1 and p53 are physiological targets for hSMG-1 in intact cells. Rapamycin in the presence of purified recombinant FKBP12 does not inhibit the kinase activity of hSMG-1. Wortmannin, the modified steroidal anti-infective agent, and the purine caffeine inhibit the kinase activity of hSMG-1 with IC₅₀ values of ∼60 nM and 0.3 mM, respectively. However, these are non-specific protein kinase inhibitors.

[0023] Specific inhibition of hSMG-1 is a potential therapeutic strategy because inhibitors of hSMG-1 cause the accumulation of truncated p53 proteins from a premature translation termination codon (PTC) allele, as well as the increase in the level of mRNA with PTC, opening the possibility of the above strategy by specifically suppressing nonsense-mediated mRNA decay (NMD) through the inhibition of hSMG-1.

[0024] One-fourth of all mutations in human genetic diseases and cancers are of the type that can target the corresponding mRNA for NMD. Although NMD protects cells against deleterious gain-of-function mutations caused by the dominant negative effects of aberrant truncated proteins, there are some cases in which the truncated protein does not show such an effect, rather, it retains residual activity and can compensate for the normal gene function. Thus, the specific inhibition of NMD may provide a novel therapeutic strategy based on the type of mutation rather than on the gene in which the mutation resides.

[0025] The inhibitors of SMG-1 can rescue the synthesis of mature proteins through two independent mechanisms (i.e., the inhibition of NMD to increase the mRNA level and the suppression of translational termination that leads to the synthesis of a read-through mature protein product). In this sense, the specific inhibitors of hSMG-1 will be of potential therapeutic importance for all the genetic diseases associated with PTC mutations.

[0026] As explained above, PI3K inhibitors, mTOR inhibitors, and hSMG-1 inhibitors are expected to be novel types of medicaments useful against cell proliferation disorders, especially as carcinostatic agents. Thus, it would be advantageous to have new PI3K inhibitors, mTOR inhibitors, and hSMG-1 inhibitors as potential treatment regimens for mTOR-, PI3K-, and hSMG-1-related diseases. The instant invention is directed to these and other important ends.

[0118] For therapeutic use, the pharmacologically active compounds of Formula I will normally be administered as a pharmaceutical composition comprising as the (or an) essential active ingredient at least one such compound in association with a solid or liquid pharmaceutically acceptable carrier and, optionally, with pharmaceutically acceptable adjutants and excipients employing standard and conventional techniques.

[0119] The pharmaceutical compositions of this invention include suitable dosage forms for oral, parenteral (including subcutaneous, intramuscular, intradermal and intravenous) bronchial or nasal administration. Thus, if a solid carrier is used, the preparation may be tableted, placed in a hard gelatin capsule in powder or pellet form, or in the form of a troche or lozenge. The solid carrier may contain conventional excipients such as binding agents, fillers, tableting lubricants, disintegrants, wetting agents and the like. The tablet may, if desired, be film coated by conventional techniques. If a liquid carrier is employed, the preparation may be in the form of a syrup, emulsion, soft gelatin capsule, sterile vehicle for injection, an aqueous or non-aqueous liquid suspension, or may be a dry product for reconstitution with water or other suitable vehicle before use. Liquid preparations may contain conventional additives such as suspending agents, emulsifying agents, wetting agents, non-aqueous vehicle (including edible oils), preservatives, as well as flavoring and/or coloring agents. For parenteral administration, a vehicle normally will comprise sterile water, at least in large part, although saline solutions, glucose solutions and like may be utilized. Injectable suspensions also may be used, in which case conventional suspending agents may be employed. Conventional preservatives, buffering agents and the like also may be added to the parenteral dosage forms. Particularly useful is the administration of a compound of Formula I directly in parenteral formulations. The pharmaceutical compositions are prepared by conventional techniques appropriate to the desired preparation containing appropriate amounts of the active ingredient, that is, the compound of Formula I according to the invention. See, for example, Remington: The Science and Practice of Pharmacy, 20th Edition. Baltimore, MD: Lippincott Williams & Wilkins, 2000.

[0120] The dosage of the compounds of Formula I to achieve a therapeutic effect will depend not only on such factors as the age, weight and sex of the patient and mode of administration, but also on the degree of potassium channel activating activity desired and the potency of the particular compound being utilized for the particular disorder of disease concerned. It is also contemplated that the treatment and dosage of the particular compound may be administered in unit dosage form and that one skilled in the art would adjust the unit dosage form accordingly to reflect the relative level of activity. The decision as to the particular dosage to be employed (and the number of times to be administered per day is within the discretion of the physician, and may be varied by titration of the dosage to the particular circumstances of this invention to produce the desired therapeutic effect.

[0121] A suitable dose of a compound of Formula I or pharmaceutical composition thereof for a mammal, including man, suffering from, or likely to suffer from any condition as described herein is an amount of active ingredient from about 0.01 mg/kg to 10 mg/kg body weight. For parenteral administration, the dose may be in the range of 0.1 mg/kg to 1 mg/kg body weight for intravenous administration. For oral administration, the dose may be in the range about 0.1 mg/kg to 5 mg/kg body weight. The active ingredient will preferably be administered in equal doses from one to four times a day. However, usually a small dosage is administered, and the dosage is gradually increased until the optimal dosage for the host under treatment is determined.

[0122] However, it will be understood that the amount of the compound actually administered will be determined by a physician, in the light of the relevant circumstances including the condition to be treated, the choice of compound of be administered, the chosen route of administration, the age, weight, and response of the individual patient, and the severity of the patient's symptoms.

[0123] The amount of the compound of the present invention or a pharmaceutically acceptable salt thereof that is effective for inhibiting mTOR or PI3K in a subject. In addition, in vitro or in vivo assays can optionally be employed to help identify optimal dosage ranges. The precise dose to be employed can also depend on the route of administration, the condition, the seriousness of the condition being treated, as well as various physical factors related to the individual being treated, and can be decided according to the judgment of a health-care practitioner. Equivalent dosages may be administered over various time periods including, but not limited to, about every 2 hours, about every 6 hours, about every 8 hours, about every 12 hours, about every 24 hours, about every 36 hours, about every 48 hours, about every 72 hours, about every week, about every two weeks, about every three weeks, about every month, and about every two months. The number and frequency of dosages corresponding to a completed course of therapy will be determined according to the judgment of a health-care practitioner. The effective dosage amounts described herein refer to total amounts administered; that is, if more than one compound of the present invention or a pharmaceutically acceptable salt thereof is administered, the effective dosage amounts correspond to the total amount administered.

[0124] In one embodiment, the compound of the present invention or a pharmaceutically acceptable salt thereof is administered concurrently with another therapeutic agent.

[0125] In one embodiment, a composition comprising an effective amount of a compound of the present invention or a pharmaceutically acceptable salt thereof and an effective amount of another therapeutic agent within the same composition can be administered.

[0126] Effective amounts of the other therapeutic agents are well known to those skilled in the art. However, it is well within the skilled artisan's purview to determine the other therapeutic agent's optimal effective amount range. The compound of the present invention or a pharmaceutically acceptable salt thereof and the other therapeutic agent can act additively or, in one embodiment, synergistically. In one embodiment, of the invention, where another therapeutic agent is administered to an animal, the effective amount of the compound of the present invention or a pharmaceutically acceptable salt thereof is less than its effective amount would be where the other therapeutic agent is not administered. In this case, without being bound by theory, it is believed that the compound of the present invention or a pharmaceutically acceptable salt thereof and the other therapeutic agent act synergistically.

[0136] As shown in Scheme 9, reaction of 3-(6-chloro-2-(4-nitrophenyl)pyrimidin-4-yl)-8-oxa-3-azabicyclo[3.2.1]octane (13) with bridged C₅-C₉heterobicycle compound 2 gave intermediate 20 containing two bridged C₅-C₉heterobicydic rings.

[0137] As shown in Scheme 10 , the mono-coupled intermediate 14 described in Scheme 5 also reacted with bridged C₅-C₉heterobicycle compound 2 to give isomeric intermediate 22 containing two bridged C₅-C₉heterobicyclic rings.

[0138] As shown in Scheme 11, reduction of the dicoupled material 15 described in Scheme 5 followed by conversion to a urea or a carbamate gave the 4,4'-pyrimidine-2,4-diyl)diuriedo or dicarbamoyl intermediate 25.

[0139] As shown in Scheme 12, reaction of 3-(2,6-dichloropyrimidin-4-yl)-8-oxa-3-azabicyclo[3.2.1]octane (9) with sodium hydroxide occurred selectively at position 2 of pyrimidine ring.

[0140] As shown in Scheme 13, reaction of the 6-chloropyrimidine produced in the previous scheme with bridged C₅-C₉heterobicycle compound 2 gave a 2-hydroxypyridine intermediate (27), the hydroxyl group of which could be reconverted to 3,3'-(2-chloropyrimidine-4,6-diyl)bis(8-oxa-3-azabicyclo[3.2.1]octane) (28).

[0141] As shown in Scheme 14, reaction of the 6-chloropyrimidine (26) produced in Scheme 12 with a simple primary amine gave a 2-hydroxypyridine intermediate (29), the hydroxyl group of which could be reconverted to 6-(8-oxa-3-azabicyclo[3.2.1]octan-3-yl)-2-chloro-N-isopropylpyrimidin-4-amine (30).

[0142] As shown in Scheme 15, reaction of the 6-chloropyrimidine (26) produced in Scheme 12 with a simple secondary alcohol gave a 2-hydroxypyridine intermediate (31), the hydroxyl group of which could be reconverted to 3-(2-chloro-6-isopropoxypyrimidin-4-yl)-8-oxa-3-azabicyclo[3.2.1]octane (32).

[0143] As shown in Scheme 16, reaction of 2,4,6-trichloropyrimidine (8) with bridged C₅-C₉heterobicycle compound 33 gave regioisomer 34 as the only isolated product. This is in contrast with the mixture of regioisomers obtained in Scheme 3 using a less hindered bridged C₅-C₉heterobicycle amine. Selective reaction at position 2 of the pyrimidine ring with iodide gave the intermediate 8-(6-chloro-2-iodopyrimidin-4-yl)-3-oxa-8-azabicyclo[3.2.1]octane (35), which served to differentiate the 2 and 6 positions of the pyrimidine ring for subsequent Suzuki coupling.

[0144] As shown in Scheme 17, reaction of 2,4,6-trichloropyrimidine (8) with phenylboronic acid occurred at position 6 of the pyrimidine ring to give 2,4-dichloro-6-phenylpyrimidine (39) as the only isolated product. This is in contrast to the amine displacement reactions of Schemes 3 and 16, which occurred largely at the 4 position. Subsequent reaction with bridged C₅-C₉heterobicycle compound 2 occurred as expected at position 4.

[0145] As shown in Scheme 18, reaction of 2,4-dichloro-6-(methylsulfonylmethyl)pyrimidine (42) with bridged C₅-C₉heterobicycle compound 2 gave the monochloro compound 43 as the only isolated product.

[0146] As shown in Scheme 19, the nitro group of 2,4,6-trichloro-5-nitropyrimidine (45) served to activate the 4 position of the pyrimidine ring in preference to the 2 position. Reaction with the bridged C₅-C₉heterobicycle compound 2 gave 3-(2,6-dichloro-5-nitropyrimidin-4-yl)-8-oxa-3-azabicyclo[3.2.1]octane (46) as the only isolated product.

[0147] In Scheme 20 is shown the synthesis of the 1-(pyridin-3-yl)-3-(4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)phenyl)urea (52) reagent for the Suzuki coupling reaction.

[0148] As shown in Scheme 12, 4-(8-oxa-3-azabicyclo[3.2.1]octan-3-yl)-6-chloropyrimidin-2-ol (26) produced in Scheme 12 was activated in the 2 position of the pyrimidine ring towards Suzuki coupling by formation of the triflate (54).

[0150] As shown in Scheme 23, the trifluoromethyl group of 2,4-dichloro-6-(trifluoromethyl)pyrimidine (62) served to activate the 4 position of the pyrimidine ring in preference to the 2 position. Reaction with the bridged C₅-C₉heterobicycle compound 2 gave 3-(2,6-dichloro-5-nitropyrimidin-4-yl)-8-oxa-3-azabicyclo[3.2.1]octane (46) as the only isolated product.

[0151] The preparation of the pyrimidine compounds I are shown in scheme 24. Starting with bis activated pyrimidine 65 where X is a leaving group, coupling with the appropriate bridged C₅-C₉heterobicycleyl amine (R¹)p-het-H reagent gave pyrimidine 66. Suzuki coupling of 66 with the appropriate amino boronic acid pinacol ester 67, boronic ester, or boronic acid leads to amino heterobicyclyl pyrimidine 68. Transformation to the amido, ureido, or carbamoyl heterobicycle compounds I is as described previously in scheme 2.

DME (7 mL) was then added to give a yellow biphasic solution. The solution was degassed with nitrogen for 10 minutes, and tetrakis(triphenylphosphine)palladium(0) (0.098 g, 0.085 mmol) and 4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)aniline (0.372 g, 1.697 mmol) were added. The vial was sealed and heated to 120°C for 40 minutes under microwave irradiation. LCMS indicated that the reaction had not gone to completion. Additional tetrakis(triphenylphosphine)palladium(0) (0.049 g, 0.043 mmol) was added and the reaction was heated to 120°C for an additional 80 minutes under microwave irradiation. The vessel was then cooled to room temperature and the reaction mixture was filtered through Celite™. The filter cake was washed with ethyl acetate and the filtrate was then concentrated under reduced pressure to provide a brown oil. The crude product was added to a silica gel column and was eluted with 0-10% methanol in methylene chloride to provide 4-(4-(3-oxa-8-azabicyclo[3.2.1]octan-8-yl)-6-((dimethylamino)methyl)pyrimidin-2-yl)aniline (0.365 g, 76 %) as a light orange solid.

BIOLOGICAL EVALUATION

PI3K-alpha and PI3K-gamma Fluorescence Polarization Assay Protocols

[0387] The reaction buffer was 20 mM HEPES, pH 7.5, 2 mM MgCl₂, 0.05% CHAPS; and 0.01% βME (added fresh). The stop/detection buffer was 100 mM HEPES, pH 7.5, 4 mM EDTA, 0.05% CHAPS; ATP 20 mM in water; PIP2 (diC8, Echelon, Salt Lake City Utah cat # P-4508) 1 mM in water (MW=856.5). The GST-GRP was 1.75 mg/mL or 1.4 mg/mL in 10% glycerol. The red detector (TAMRA) was 2.5 µM. Nunc 384-well black polypropylene fluorescent plates were used for PI3K assays.

[0388] The assay is run by placing 5 µL of diluted enzyme per well, then 5 µL of diluted compound (or 9.5 µL enzyme then 0.5 µL compound in DMSO) is added and mixed. Then, 10 µL substrate is added to start the reaction. The samples are incubated 30-60 minutes, then the reaction is stopped by adding 20 µL stop/detector mix. PI3K is diluted with reaction buffer (e.g., 5 µL or 7.5 µL PI3K into 620 µL reaction buffer), and 5 µL of diluted enzyme is used per well. A 5 µL portion of reaction buffer or of drug diluted in buffer (e.g., 4 µL/100 so final DMSO is 1% in reaction) is added to each. Pipetting up and down mixes the samples. Alternatively, the enzyme can be diluted to 1215 µL. In this case 9.8 µL is added per well and 0.2 µL compound is added in DMSO.

[0389] To prepare 1 mL of substrate solution, 955 µL reaction buffer, 40 µL PIP2, and 2.5 µL ATP are mixed. 10 µL of substrate is added to each well to start the reaction. This results in 20 µM PIP2, and 25 µM ATP per reaction. The stop/detector mix is prepared by mixing 4 µL red detector and 1.6 µL or 2.0 µL GST-GRP with 1 mL stop buffer, which results in 10 nM probe and 70 nM GST-GRP. 20 µL of the stop/detector mix is added to each well to stop the reaction. The plates are read after 30-90 minutes keeping the red probe solutions dark. For the zero time point, stop/detector mix is added to the enzyme just before adding substrate. For an extra control, stop/detector mix is added to buffer (no enzyme) and substrate or to just buffer (no substrate). Pooled PI3K preparations had a protein concentration of 0.25 mg/mL. The recommended reaction has 0.06 µL per 20 µL (0.015 µg/20 µL) or 0.01125 µg/15 µL or 0.75 µg/mL.

[0390] Plates are read on machines with filters for TAMRA. The units are mP with no enzyme controls reading app 190-220 mP units. Fully active enzyme reduces fluorescence polarization down to 70-100 mP after 30 minutes. An active compound raises the mP values halfway to control or to 120-150 mP units. Compounds of the invention had IC₅₀s against PI3K-alpha ranging from 7 nM to 2,858 nM.

mTOR Enzyme Assay

[0391] (See Toral-Barza, et al. Biochem Biophys. Res. Commun. 2005 June 24;332(1):304-10) The routine human TOR assays with purified enzyme were performed in 96-well plates by DELFIA format as follows. Enzymes were first diluted in kinase assay buffer (10 mM HEPES (pH 7.4), 50 mM NaCl, 50 mM β-glycerophosphate, 10 mM MnCl₂, 0.5 mM DTT, 0.25 µM microcystin LR, and 100 µg/mL BSA). To each well, 12 µL of the diluted enzyme were mixed briefly with 0.5 µL test inhibitor or the control vehicle dimethylsulfoxide (DMSO). The kinase reaction was initiated by adding 12.5 µL kinase assay buffer containing ATP and His6-S6K to give a final reaction volume of 25 µL containing 800 ng/mL FLAG-TOR, 100 µM ATP and 1.25 µM His6-S6K. The reaction plate was incubated for 2 hours (linear at 1-6 hours) at room temperature with gentle shaking and then terminated by adding 25 µL Stop buffer (20 mM HEPES (pH 7.4), 20 mM EDTA, 20 mM EGTA). The DELFIA detection of the phosphorylated (Thr-389) His6-S6K was performed at room temperature using a monoclonal anti-P(T389)-p70S6K antibody (1A5, Cell Signaling) labeled with Europium-N1-ITC (Eu) (10.4 Eu per antibody, PerkinElmer). The DELFIA assay buffer and enhancement solution were purchased from PerkinElmer. 45 µL of the terminated kinase reaction mixture was transferred to a MaxiSorp plate (Nunc) containing 55 µL PBS. The His6-S6K was allowed to attach for 2 hours after which the wells were aspirated and washed once with PBS. 100 µL of DELFIA assay buffer with 40 ng/mL Eu-P(T389)-S6K antibody was added. The antibody binding was continued for 1 hour with gentle agitation. The wells were then aspirated and washed 4 times with PBS containing 0.05% Tween-20 (PBST). 100 µL of DELFIA enhancement solution was added to each well and the plates were read in a PerkinElmer Victor model plate reader. Data obtained were used to calculate enzymatic activity and enzyme inhibition by potential inhibitors. Compounds of the invention had IC₅₀ activities ranging from <1 nM to 580 nM.

In vitro cell growth assay

[0392] The cell lines used were human prostate lines LNCap and PC3MM2, human breast lines MDA468 and MCF7, human renal line HTB44 (A498), human colon line HCT116, and human ovarian line OVCAR3. Cells were plated in 96-well culture plates. One day following plating, the inhibitors were added to cells. Three days after drug treatment, viable cell densities were determined by metabolic conversion (by viable cells) of the dye MTS, a well-established cell proliferation assay. The assays were performed using an assay kit purchased from Promega Corp. (Madison, WI) following the protocol supplied with the kit. The MTS assay results were read in a 96-well plate reader by measuring absorbance at 490 nm. The effect of each treatment was calculated as percent of control growth relative to the vehicle-treated cells grown in the same culture plate. The drug concentration that conferred 50% inhibition of growth was determined as IC₅₀. Compounds of the invention had IC₅₀ activities against LNCAP cells ranging from 6 nM to >60 uM.

[0393] Table 1 shows the results of the described biological assays.
