FIELD OF THE INVENTION
[0002] The present invention relates generally to compounds useful in treatment of conditions associated with excessive activity of transforming growth factor beta (TGF-P), particularly type 1 or activin-like kinase 5 (ALK 5). The invention also provides method of using said compounds and pharmaceutically acceptable compositions comprising compounds of the present invention.
BACKGROUND OF THE INVENTION
[0003] Transforming growth factors, including TGF-P, play a key role in controlling cellular functions such as proliferation, differentiation, migration, extracellular matrix production, apoptosis, adhesion, and development. Dysregulated TGF-P signaling has been identified as a key factor in a number of pathological disorders.
[0004] TGF-P and other cytokines signal through a complex of two structurally and functionally distinct transmembrane receptor serine/threonine kinases, known as type 1 and type 2 TGF-P receptors, resulting in activation of TGF-P mediated pathways. The type 1 TGF-P receptor is also known as activin-like kinase 5 (ALK 5). Inhibition of ALK 5 antagonizes TGF-P mediated pathways and provides diverse biological effects in clinical applications, including the treatment of cancer, fibrosis, cardiovascular disorders, wound healing, and many others.
[0005] TGF-P superfamily of conserved cytokines, growth factors, and morphogens consists of isoforms TGF-pi (ALK 5), TGF-P2, and TGF-P3. These
proteins are pleiotropic modulators that regulates various biological processes including cell growth and differentiation, stimulating cell proliferation, inducing apoptosis, hematopoiesis, embryonic and bone development, immune and inflammatory responses and extracellular matrix formation (Roberts and Sporn Handbook of Experimental Pharmacology (1990) 95:419-58; Massague, et al, Ann. Rev. Cell. Biol. (1990) 6:597-646). Among the various isoforms, TGF-pi inhibits the growth of epithelial cells and stimulates the proliferation of mesenchymal cells. Activin, inhibin, bone morphogenic protein, and Mullerian inhibiting substance (MIS) are other members of this superfamily. TGF-P superfamily members are responsible for initiation of intracellular signaling pathways that ultimately leads to gene expressions that regulate cell cycle. The TGF-P superfamily also control proliferative responses, cell adhesion, intercellular communication, cellular migration and relate with extracellular matrix proteins that mediate outside-in cell signaling.
[0006] As TGF-P regulates many biological processes, dysregulation in its activity can be harmful. For example, TGF-P stimulates the proliferation of mesenchymal cells under normal conditions, however when dysregulated, TGF-P can be an autocrine growth factor for many tumors. Similarly, overexpression of TGF-P can lead to an excessive accumulation of extracellular matrix resulting in fibroproliferative diseases. Hence, there is need to develop compounds that modulate the TGF-P signaling pathway.
[0007] Inhibition of TGF-P intracellular signaling pathway can be primarily recognized for treatment of fibroproliferative diseases and cancer. Fibroproliferative diseases mainly involve kidney disorders that are associated with dysregulation of TGF-P activity and excessive fibrosis. The excessive fibrosis includes glomerulonephritis (GN) in form of mesangial proliferative GN, immune GN, and crescentic GN. Diabetic nephropathy, renal interstitial fibrosis and renal fibrosis in transplant patients receiving cyclosporine, and HIV-associated nephropathy are other renal conditions with enhanced TGF-P activity. Dermatomyositis, Eosinophilic fasciitis (Shulman's Syndrome), morphea,
polymyositis, progressive systemic sclerosis, scleroderma, or those associated with the occurrence of Raynaud's syndrome are forms of collagen vascular disorders. In addition, excessive TGF-P activity can also contribute to lung fibroses that in turn include adult respiratory distress syndrome, chronic obstructive pulmonary disease (COPD), idiopathic pulmonary fibrosis and interstitial pulmonary fibrosis. Interstitial pulmonary fibrosis is usually associated with allergies, chemical contact, scleroderma and autoimmune disorders, such as systemic lupus erythematosus. Rheumatoid arthritis is another autoimmune disorder associated with fibroproliferative characteristics. Surgical eye procedures can also be linked with fibroproliferative conditions. These procedures include cataract extraction with intraocular lens implantation, post glaucoma drainage surgery and retinal reattachment surgery accompanying proliferative vitreoretinopathy.
[0008] Progression of various cancers is also mediated through members of the TGF-P superfamily (M. P. de Caestecker, E. Piek, and A. B. Roberts, J. National Cancer Inst., 92(17), 1388-1402 (2000) as these members are overexpressed significantly in many tumors. (Derynck, Trends Biochem. Sci., 1994, 19, 548-553). For example, TGF-pior ALK 5 is known to inhibit tumor formation by inhibition of the proliferation of non-transformed cells, however it promotes tumor growth once the tumor is formed. (N. Dumont and C. L. Arteaga, Breast Cancer Res., Vol. 2, 125-132 (2000)). Therefore, inhibition of the TGF-P pathway may be useful for the treatment of different types of cancer such as colorectal cancer, lung cancer and skin cancer. Particularly, TGF-P inhibition can be utilized for treatment of breast cancer, brain cancer, pancreatic cancer and glioma.
[0009] Many TGF-P inhibitors based on dihydropyrrolopyrazole, pyrazole, quinazoline, and imidazole cores were discovered by several companies including Eli Lilly, Scios, Biogen Idee, GlaxoSmithKline, Kyoto Pharmaceutical University and Kirin Brewery Company {Current Pharmaceutical Biotechnology, 2011, 72, 2190-2202). Among the reported small molecule TGF-P inhibitors, Eli Lilly's
LY2157299, Medpacto's TEW 7197 and Merck's M7824 were progressed to clinical trials. Fresolimumab, developed by Cambridge Antibody Technology, is a human monoclonal antibody targeting all isoforms of TGF-P which is currently in phase 2 clinical trials.
[00010] Small molecule modulator of TGF-P are described in patents/patent applications WO2005/065691 (PCT/US2004/043503), US 13 508090, WO2011/146287A1, WO2004/065392, WO2009/050183, and WO2009/133070 (see for more examples). Antibodies to TGF-P have been described in U.S. Pat.
Nos. 7,527,791; 7,927.593; 7,494,651; 7,369,111; 7,151,169; 6,492,497; 6,419,928; 6,090,383; 5,783,185; 5,772,998; 5,571,714; and 7,723,486.
[00011] There remains a continuing need for new therapies for the treatment of diseases and disorders related to the TGF-P dysregulation. Therefore, the present invention provides inhibitors of ALK 5.

[00034] A "pharmaceutically acceptable carrier" refers to an ingredient in a pharmaceutical formulation, other than an active ingredient, which is nontoxic to a subject. A pharmaceutically acceptable carrier includes, but is not limited to, a buffer, excipient, stabilizer, or preservative.
[00035] As used herein, "treatment" or "treating" is an approach for obtaining beneficial or desired results including clinical results. For example, beneficial or desired results include, but are not limited to, one or more of the following: decreasing symptoms resulting from the disease, increasing the quality of life of those suffering from the disease, decreasing the dose of other medications required to treat the disease, delaying the progression of the disease, and/or prolonging survival of individuals. In reference to cancers or other unwanted cell proliferation, beneficial or desired results include shrinking a tumor (reducing tumor size); decreasing the growth rate of the tumor (such as to suppress tumor growth); reducing the number of cancer cells; inhibiting, retarding or slowing to some extent and preferably stopping cancer cell infiltration into peripheral organs; inhibiting (slowing to some extent and preferably stopping) tumor metastasis; inhibiting tumor growth; preventing or delaying occurrence and/or recurrence of tumor; and/or relieving to some extent one or more of the symptoms associated with the cancer. In some embodiments, beneficial or desired results include preventing or delaying occurrence and/or recurrence, such as of unwanted cell proliferation.
[00036] As used herein, "delaying development of a disease" means to defer, hinder, slow, retard, stabilize, and/or postpone development of the disease (such as cancer). This delay can be of varying lengths of time, depending on the history of the disease and/or individual being treated. As is evident to one skilled in the art, a sufficient or significant delay can, in effect, encompass prevention, in that the individual does not develop the disease. For example, a late stage cancer, such as development of metastasis, may be delayed.
[00037] As used herein, an "effective dosage" or "effective amount" of compound or salt thereof or pharmaceutical composition is an amount sufficient to effect beneficial or desired results. For prophylactic use, beneficial or desired results include results such as eliminating or reducing the risk, lessening the severity of, or delaying the onset of the disease, including biochemical, histological and/or behavioral symptoms of the disease, its complications and
intermediate pathological phenotypes presenting during development of the disease. For therapeutic use, beneficial or desired results include ameliorating, palliating, lessening, delaying or decreasing one or more symptoms resulting from the disease, increasing the quality of life of those suffering from the disease, decreasing the dose of other medications required to treat the disease, enhancing effect of another medication such as via targeting, delaying the progression of the disease, and/or prolonging survival. In reference to cancers or other unwanted cell proliferation, an effective amount comprises an amount sufficient to cause a tumor to shrink and/or to decrease the growth rate of the tumor (such as to suppress tumor growth) or to prevent or delay other unwanted cell proliferation.
