The present invention relates to novel pyrimidine compounds and their use in treating PI3K kinase- and/or mTOR kinase-related diseases.
The 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. There are two important effects as mTOR inhibitors bind to the mTOR kinase. 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 antiangiogenesis via the lowering of VEGF levels. These anticancer drugs have shown exceptional promise in cancer therapy and may change the way many types of cancer are treated.
Several studies have demonstrated that mTOR has a central role in controlling cell growth, proliferation and metabolism. mTOR regulates a wide range of cellular functions, including translation, transcription, mRNA turnover, protein stability, actin cytoskeletal organization and autophagy. mTOR is a member of the phosphoinositide kinase-related kinase (PIKK) family, but is not a phosphorylating phosphoinositide, a phosphorylate protein on serine or a threonine residue. There are two mTOR complexes in mammalian cells. mTOR complex I (mTORC1) is a raptor-mTOR complex, which mainly regulates cell growth in a rapamycin-sensitive manner, whereas mTOR complex II (mTORC2) is a rictor-mTOR complex, which regulates cytoskeletal organization in a rapamycin-insensitive manner.
Kinase subunits of both mTORC1 and mTORC2 regulate cell growth and survival in response to nutrient and hormonal signals. mTORC1 is activated in response to growth factors or amino-acids. Amino-acid-signaling to mTORC1 is mediated by Rag GTPases, which cause amino-acid-induced relocalization of mTOR within the endomembrane system. Growth-factor-stimulated mTORC1 activation involves AKT1-mediated phosphorylation of TSC1-TSC2, which leads to the activation of the Rheb GTPase that potently activates the protein kinase activity of mTORC1. Activated mTORC1 up-regulates protein synthesis by phosphorylating key regulators of mRNA translation and ribosome synthesis. mTORC1 phosphorylates eIF4EBP1 and releases it from inhibiting the elongation initiation factor 4E (eIF4E). mTORC1 phosphorylates and activates S6K1 at Thr-421, which then promotes protein synthesis by phosphorylating PDCD4 and targeting it for degradation. mTORC2 is also activated by growth factors, but seems to be nutrient-insensitive. mTORC2 seems to function upstream of Rho GTPases to regulate the actin cytoskeleton, probably by activating one or more Rho-type guanine nucleotide exchange factors. mTORC2 promotes the serum-induced formation of stress-fibers or F-actin. mTORC2 plays a critical role in AKT1 Ser-473 phosphorylation, which may facilitate the phosphorylation of the activation loop of AKT1 on Thr-308 by PDK1, which is a prerequisite for full activation. mTORC2 regulates the phosphorylation of SGK1 at Ser-422. mTORC2 also modulates the phosphorylation of PRKCA on Ser-657.
With the recent discovery of rapamycin independent function of mTOR (by mTOR2) in phosphorylation AKT (at S473), which is important in regulation of cell survival and modulation of PKCα, which plays a major role in regulation of actin cytoskeletal organization, it is believed that inhibition of mTOR function by rapamycin is partial. Therefore, a small molecule designed to compete with ATP in the catalytic site of mTOR would be expected to inhibit all of the kinase-dependent functions of mTORC1 and mTORC2, unlike rapalogs that only target mTORC1. Here we describe the discovery of direct mTOR kinase inhibitors which can be used in the treatment of a variety of cancers, including breast, lung, kidney, prostate, blood, liver, and ovarian cancers, and lymphoma and other indications such as rheumatoid arthritis, hamartoma syndromes, transplant rejection, multiple sclerosis and immunosuppression.
Phosphatidylinositol (hereinafter abbreviated as “PI”) is one of the phospholipids in cell membranes. In recent years it has become clear that PI also plays an important role in intracellular signal transduction. In particular, it is well recognized in the art that PI (4,5) bisphosphate (PI(4,5)P2) 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)].
PI3K was originally considered to be a single enzyme, but it has now been clarified that a plurality of subtypes is present in PI3K. Each subtype has its own mechanism for regulating activity. The PI3K family comprises at least 15 different enzymes sub-classified by structural homology and divided into 3 classes based on sequence homology and the product formed by enzyme catalysis. The class I PI3 kinases are composed of 2 subunits: a 110 kd catalytic subunit and an 85 kd regulatory subunit. The regulatory subunits contain SH2 domains and bind to tyrosine residues phosphorylated by growth factor receptors with a tyrosine kinase activity or oncogene products, thereby inducing the PI3K activity of the p110α catalytic subunit which phosphorylates its lipid substrate. Class I PI3Ks are further divided into two groups, class Ia and class Ib, in terms of their activation mechanism. Class Ia PI3Ks include PI3K p110α, p110β and p110δ subtypes, which transmit signals from tyrosine kinase-coupled receptors. Class Ib PI3K includes a p110γ subtype activated by a G protein-coupled receptor. PI and PI(4)P are known as substrates for class II PI3Ks. Class II PI3Ks include PI3K C2α, C2β and C2γ subtypes, which are characterized by containing C2 domains at the C terminus. The substrate for class III PI3Ks is PI only.
Most if not all of the non-rapalog mTOR inhibitors described to date in the scientific literature were developed to inhibit other enzymes, especially class I PI3Ks. Because PI3K regulates mTOR activity, inhibitors that target both enzymes are generally not useful as research tools to study mTOR regulation or function. However, drugs that are dual PI3K/mTOR inhibitors might have a therapeutic advantage over single-target inhibitors in certain disease settings. PI3K inhibitors and mTOR 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 mTOR inhibitors and PI3K inhibitors as potential treatment regimens for mTOR kinase- and PI3K kinase-related diseases.
It has now been found that a series of novel pyrimidine compounds have activity as inhibitors of mTOR and PI3K. Accordingly, the present invention provides a compound of formula (I):

It has now been found that a series of novel pyrimidine compounds have inhibitory activity against the PI3K enzymes and the class IV kinase mTOR. It is now well understood that deregulation of oncogenes and tumour-suppressor genes contributes to the formation of malignant tumours, for example, by way of increased cell proliferation or increased cell survival. It is also now known that signaling pathways mediated by the PI3K/mTOR families have a central role in a number of cell processes, including proliferation and survival, and deregulation of these pathways is a causative factor in a wide spectrum of human cancers and other diseases.
The compounds of the present invention have been found to be inhibitors of mTOR kinase and PI3 kinase. The pharmacological inhibitors of mTOR kinase and PI3 kinase should be of therapeutic value for treatment of various forms of cancer comprising solid tumors such as carcinomas, sarcomas, leukaemias and lymphoid malignancies. Accordingly, a compound of the present invention can be used to treat a disease or disorder arising from abnormal cell growth, function or behaviour associated with mTOR kinase and PI3 kinase.
Also within the scope of this invention are a pharmaceutical composition that contains an effective amount of at least one of the pyrimidine compounds of formula (I) or a stereoisomer, or a tautomer, or an N-oxide, or a pharmaceutically acceptable salt, or an ester, or a prodrug, or a hydrate, or a solvate thereof together with a pharmaceutically acceptable carrier, a method for treating a PI3K kinase-/mTOR kinase-related disease (e.g., cancer) by administering to a subject in need of this treatment an effective amount of the pyrimidine compounds of formula (I), and a method of decreasing the activity of at least one PI3K kinase and mTOR kinase by contacting the at least one PI3K kinase and mTOR kinase with at least one of the pyrimidine compounds of formula (I).
As used herein, the term “PI3 kinase-/mTOR kinase-related disease” refers to a disease or condition that is characterized by abnormal PI3 and/or mTOR activity or a disease or condition that can be treated with changes to the activity of at least one of PI3 and mTOR. Abnormal PI3 and/or mTOR activity can arise as the result of elevated PI3 and/or mTOR expression level, or presence of PI3 and/or mTOR expression that does not occur in normal conditions. PI3 kinase-/mTOR kinase-related diseases described herein include, but are not limited to, cancer, diabetes, immune disorders, hyper-proliferation disorders, hyperproliferative disorders of the kidney, renal disease, von Hippel-Lindau disease, restenosis, fibrosis, psoriasis, osteoarthritis, rheumatoid arthritis, inflammatory disorders, immunological disorders such as autoimmune diseases (e.g., AIDS, lupus, etc.), cardiovascular disorders (e.g. atherosclerosis), and blood vessel proliferative disorders such as abnormal vasculogenesis.
The term “treating” refers to administering a pyrimidine compound of formula (I) to a subject that has a PI3 kinase-/mTOR kinase-related disease, or has a symptom of or a predisposition toward it, with the purpose to cure, heal, alleviate, relieve, alter, remedy, ameliorate, improve, affect or reduce the risk of the disorder, or the symptoms of or the predisposition toward the disorder. For example, treating cancer refers to treatment resulting in inhibition of cancer growth or cancer cell growth, regression in cancer growth (i.e. reducing the size of a detectable cancer), or disappearance of a cancer. The term “an effective amount” refers to the amount of the active agent that is required to confer the intended therapeutic effect in the subject. Effective amounts may vary, as recognized by those skilled in the art, depending on route of administration, the excipient used, and the possibility of co-usage with other agents. The subject in need of the treatment can be a mammal. The term “mammal” refers to human or nonhuman mammal, for example, dogs, cats, pigs, cows, sheep, goats, horses, rats, or mice.
Cancer that can be treated by the methods of the invention is any abnormal cell or tissue growth, for example, a tumor, whether malignant, pre-malignant, or non-malignant. It is characterized by uncontrolled proliferation of cells that may or may not invade the surrounding tissue and, hence, may or may not metastasize to new body sites. Cancer encompasses carcinomas, which are cancers of epithelial cells; carcinomas include squamous cell carcinomas, adenocarcinomas, melanomas, and hepatomas. Cancer also encompasses sarcomas, which are tumors of mesenchymal origin; sarcomas include osteogenic sarcomas, leukemias, and lymphomas. Cancers may involve one or more neoplastic cell type. The term cancer includes, as non-limiting examples, lung cancer, colon cancer, colorectal cancer, breast cancer, prostate cancer, liver cancer, pancreatic cancer, bladder cancer, gastric cancer, renal cancer, salivary gland cancer, ovarian cancer, uterine body cancer, cervical cancer, oral cancer, skin cancer, brain cancer, lymphoma, and leukemia. The cancers also include Epidermal Growth Factor Receptor (EGFR) dependent cancers or cancers that resist to EGFR targeting agent.
The compounds described herein can be administered to a mammal in conjunction with radiation therapy, immunotherapy, monoclonal antibody therapy, hormonal therapy, chemotherapy using other agents, and/or surgery. “In conjunction with” means that the therapies do not need to occur at the same time, and can be in succession, or alternate with each other and/or periods of rest and recovery.
In one embodiment, a PI3 kinase-/mTOR kinase-related disease, such as cancer, can be treated with a method comprising administering an effective amount of at least a pyrimidine compound of formula (I) and at least one chemotherapeutic agent to a mammal. Non-limiting examples of chemotherapeutic agent include protein kinase inhibitors other than the compound described herein (e.g., imatinib mesylate, gefitinib, dasatinib, erlotinib, lapatinib, sunitinib, nilotinib, and sorafenib; antibodies, including, e.g., trastuzumab, rituximab, cetuximab, and bevacizumab; mitoxantrone; dexamethasone; prednisone; and temozolomide), alkylating agents (e.g., melphalan, chlorambucil, busulfan, thiotepa, ifosfamide, carmustine, lomustine, semustine, streptozocin, decarbazine, and cyclophosphamide), mitotic inhibitors, antimetabolites (e.g., capecitibine, gemcitabine, 5-fluorouracil or 5-fluorouracil/leucovorin, fludarabine, cytarabine, mercaptopurine, thioguanine, pentostatin, and methotrexate), cell cycle inhibitors, enzymes, hormones, anti-hormones, growth-factor inhibitors, plant alkaloids and terpenoids, topoisomerase inhibitors (e.g., etoposide, teniposide, camptothecin, topotecan, irinotecan, doxorubicin, and daunorubicin), antitumor antibiotics (e.g., actinomycin D, bleomycin, mitomycin C, adriamycin, daunorubicin, idarubicin, doxorubicin and pegylated liposomal doxorubicin), vinca alkaloids (e.g., vincristine and vinblastin), taxanes (e.g., paclitaxel and docetaxel), platinum agents (e.g., cisplatin, carboplatin, and oxaliplatin), thalidomide and related analogs (e.g., CC-5013 and CC-4047), monoclonal antibodies, antiangiogenic agents, and combinations thereof.
To practice the method of this invention, the above-described pharmaceutical composition can be administered orally, parenterally, by inhalation spray, topically, rectally, nasally, buccally, vaginally or via an implanted reservoir. The term “parenteral” as used herein includes subcutaneous, intracutaneous, intravenous, intramuscular, intraarticular, intraarterial, intrasynovial, intrasternal, intrathecal, intralesional, and intracranial injection or infusion techniques. In one embodiment, the pharmaceutical composition of this invention is administered intravenously. The pharmaceutically acceptable carriers may include, but are not limited to, water, Ringer's solution, isotonic sodium chloride solution or phosphate buffered saline, and solutions containing thickening and solubilizing agents, such as glucose, polyethylene glycol, and polypropylene glycol and mixtures thereof.
A sterile injectable composition can be formulated according to techniques known in the art using suitable dispersing or wetting agents and suspending agents. The sterile injectable preparation can also be a sterile injectable solution or suspension in a non-toxic parenterally acceptable diluent or solvent. Among the acceptable vehicles and solvents that can be employed are mannitol, water, Ringer's solution and isotonic sodium chloride solution. Fatty acids, such as oleic acid and its glyceride derivatives, are useful in the preparation of injectables, as are natural pharmaceutically-acceptable oils, such as olive oil or castor oil, especially in their polyoxyethylated versions. These oil solutions or suspensions can also contain a long-chain alcohol diluent or dispersant, or carboxymethyl cellulose or similar dispersing agents. Other commonly used surfactants such as Tweens or Spans or other similar emulsifying agents or bioavailability enhancers which are commonly used in the manufacture of pharmaceutically acceptable solid, liquid, or other dosage forms can also be used for purposes of formulation.
A composition for oral administration can be any orally acceptable dosage form including, but not limited to, capsules, tablets, emulsions and aqueous suspensions, dispersions and solutions. In the case of tablets for oral use, carriers that are commonly used include lactose and corn starch. Lubricating agents, such as magnesium stearate, are also typically added. For oral administration in a capsule form, useful diluents include lactose and dried corn starch. When aqueous suspensions or emulsions are administered orally, the active ingredient can be suspended or dissolved in an oily phase combined with emulsifying or suspending agents. If desired, certain sweetening, flavoring, or coloring agents can be added. A nasal aerosol or inhalation composition can be prepared according to techniques well known in the art of pharmaceutical formulation. The composition of the present invention may also be administered in the form of suppositories for rectal administration.
Suitable in vitro assays can be used to preliminarily evaluate the efficacy of the pyrimidine compounds of formula (I) in anticancer activities such as inhibiting growth of tumor cells. The compounds can further be examined for their efficacy in treating cancer. For example, a compound can be administered to an animal (e.g., a mouse model) having cancer and its therapeutic effects then assessed. Based on the results, an appropriate dosage range and administration route can also be determined.
The invention will be further described in the Examples as follows. The examples given below are intended to be illustrative only and not to limit the invention. Any modifications and variations that can be easily made by those skilled in the art fall within the scope of the disclosure of the specification and the appended claims of the present invention.

5-iodouracil (476 mg, 2 mmole) was placed in a dry and argon-flushed Schlenk-tube equipped with a magnetic stirring bar and a septum. With vigorous stirring, the substrate was dried for 15 min in high vacuum to exclude the presence of water in the hygroscopic substrate. Then, a solution of LiCl in THF (0.5M; 8 ml; 4 mmole, 2.0 eq) was added and after stirring for some minutes at r.t., the substrate dissolved to give a clear and colourless solution. The solution was cooled to −20° C. and MeMgCl (3M in THF; 1.33 ml, 4 mmole, 2 eq) was added dropwise. After completion of the addition, the resulting clear solution was stirred at −20° C. for 20 min. Afterward, i-PrMgCl (1.32 M in THF; 1.82 ml, 2.40 mmole, 1.20 eq) was added slowly and the resulting mixture was allowed to warm up to room temperature. After one hour, a thick, grayish slurry had formed and the mixture was cooled to −20° C. and S-methyl methanesulfonothioate (328 mg, 2.6 mmole, 1.3 eq) was obtained. Afterwards, the mixture was warmed up to r.t. and stirred at that temperature until TLC indicated completion of the reaction. After quenching with MeOH, the mixture was transferred to a separation funnel containing water (40 ml). By careful addition of 2.0 M HCl, the pH of the mixture was adjusted to ca. 5-6. The aqueous layer was extracted with EA, the combined organic layers were dried (Na2SO4) and evaporated. Recrystallization from MeOH afforded the product as a colorless, crystalline solid which was dried in high vacuum (64%).

The compounds of the invention, prepared as described in the examples, were subject to the following series of biological assays. Brief descriptions of different assays are as follows.
A549, HCT-116, and A498 cell lines were purchased from the Bioresource Collection and Research Center (BCRC, Taiwan) and cultured in Dulbecco's Modified Eagle Medium (DMEM, Sigma) containing 10% fetal bovine serum (FBS, HyClone). PC-3, U-87 MG, HCC1954 and BT474 cell lines were purchased from the American Type Culture Collection (ATCC, USA). PC-3 was grown in F12K medium (GIBCO) containing 10% FBS. U-87 MG was grown in Eagle's minimum essential medium (MEM, Sigma) supplemented with nonessential amino acids, L-glutamine, sodium pyruvate, and 10% FBS. HCC1954 was grown in RPMI medium (GIBCO) containing 10% FBS. BT-474 was grown in DMEM medium (GIBCO) containing 10% FBS. All cells were incubated in a humidified atmosphere containing 5% CO2 at 37° C.
Cell lines were inoculated to the wells of a 96-well culture plate with 1000-5000 cells per well. The compounds were prepared and used to treat cells with less than 1% DMSO. After 72 hours of drug treatment, the viability of each cell line was examined by CellTiter 96 Aqueous Non-Radioactive Cell Proliferation Assay (Promega). The living cells were detectable by conversion of MTS into aqueous, soluble formazan. MTS/PMS solution was freshly prepared and 20 μl of MTS/PMS solution was added to each well of the 96-well cultured plate. The assay plate was incubated for 3 hours and the absorbance at 490 nm was measured by EMax ELISA Reader (Molecular Devices). The IC50 values of compounds were determined after carrying out assays at eight serially diluted concentrations of each compound in triplicate, and are the mean of three separate determinations. The results were analyzed using linear regression software (GraphPad Prism 5; GraphPad Software Inc.).
For immunoblotting experiments, A549 cells were inoculated to the wells of a 6-well culture plate and cultured overnight. Cells were incubated with the compound for 30 min and 24 hours and whole cell lysate was harvested by adding 1×SDS Sample Buffer (62.5 mM Tris-HCl (pH 6.8 at 25° C.), 2% w/v SDS, 10% glycerol, 50 mM DTI, and 0.01% w/v bromophenol blue or phenol red). Proteins were separated by SDS-PAGE electrophoresis and transferred to PVDF membrane. Protein expression was immunobloted by various primary antibodies and detected by Immobilon Western Chemiluminescent HRP Substrate (Millipore). Antibody against Akt, phosphor-Akt (Ser473), phosphor-Akt (Thr308), p70 S6 Kinase, phosphor-p70 S6 Kinase (Thr389), 4E-BP1, and phosphor-4E-BP1 (Thr37/46) were purchased form Cell Signaling Technology.
(3) mTOR Kinase Assay
The activity of the compound against mTOR was examined by measuring the incorporation of 33P from [γ-33P]-ATP into 4EBP1. His-tagged, recombinant human 4EBP1 was expressed in E. coli, purified by nickel-nitrilotriacetic acid (Ni-NTA) resins, and stored at −80° C. Phosphorylation of 4EBP1 by mTOR was assayed in the presence or absence of the compound and performed in a final volume of 25 μl reaction buffer containing 300 ng 4EBP1, 50 ng recombinant mTOR (Invitrogen), 50 mM HEPES (pH 7.5), 1 mM EGTA, 0.01% Polysorbate 20, 10 mM MnCl2, 2.5 mM DTT, 10 μM ATP, and 0.5 μCi [γ-33P]-ATP (PerkinElmer) for 30 min at 30° C. The reactions were terminated by adding 3% phosphoric acid. The 33P labeled 4EBP1 was transferred onto UniFilter-96 GF/B plate (PerkinElmer) and quantified by Top Count Microplate Scintillation Counter (PerkinElmer). For primary screening of kinase activity inhibition, each test compound was evaluated at 10 M in duplicate. The results were the average of duplicate measurements and expressed as percentage inhibition (compound treatment versus DMSO control). The IC50 values of the compounds were determined after carrying out assays at eight serially diluted concentrations of each compound in duplicate. The results were analyzed using linear regression software (GraphPad Prism 5; GraphPad Software Inc.).
The ability of compounds at 500 nM against phosphatidylinositide 3-kinase (PI3K) was verified by PI3K HTRF Assay. Recombinant PI3K (p110α/p85α) and PI3K (p110β/p85α) were from Millipore. Enzyme reactions were performed according to the manufacturer's suggestions. Briefly, the compounds of interest dissolved in 100% DMSO were dispensed in all wells, following which the mixture of PIP2 and enzyme was added. PI3K (p110α/p85α) and PI3K (p110β/p85α) enzyme reactions were initiated in the presence of 10 μM and 100 μM ATP, respectively, and incubated for 30 min at room temperature. STOP solution prepared 2 hours prior to use was added to stop reactions, and mixed well. Detection solution prepared 2 hours prior to use was added, and incubated at room temperature for 17 hours in the dark. Fluorescence was measures by Packard Fusion Alpha Microplate Analyzer with excitation at 340 nm and emission at 620 nm and 665 nm. HTRF ration was calculated as follows:
