  • Publication number: 20090099178
    Abstract: This invention is directed to Indazole Compounds or pharmaceutically acceptable salts, solvates and hydrates thereof. The Indazole Compounds have utility in the treatment or prevention of a wide range of diseases and disorders that are responsive to the inhibition, modulation or regulation of kinases, such as inflammatory diseases, abnormal angiogenesis and diseases related thereto, cancer, atherosclerosis, a cardiovascular disease, a renal disease, an autoimmune condition, macular degeneration, disease-related wasting, an asbestos-related condition, pulmonary hypertension, diabetes, obesity, pain and others. Thus, methods of treating or preventing such diseases and disorders are also disclosed, as are pharmaceutical compositions comprising one or more of the Indazole Compounds. This invention is based, in part, upon the discovery of a novel class of 5-triazolyl substituted indazole molecules that have potent activity with respect to the modulation of protein kinases.
