ABSTRACT:
The present invention relates generally to novel amine substituted oxindole compounds and compositions having utility as pharmacological agents in treating diseases or conditions alleviated by the inhibition or antagonism of protein kinase activated signalling pathways in general, and in particular in the pathological processes which involve aberrant cellular proliferation, such as tumor growth, restenosis, atherosclerosis, and thrombosis and methods for using and manufacturing such compounds. In particular, the present invention relates to a series of substituted oxindole compounds, which exhibit protein tyrosine kinase and protein serine/threonine kinase inhibition, and which are useful in inhibiting tumor growth via inhibition of tumor-related angiogenesis.
BACKGROUND OF THE INVENTION
Protein kinases play a critical role in the control of cell growth and differentiation and are key mediators of cellular signals leading to the production of growth factors and cytokines. See, for example, Schlessinger and Ullrich,

Nature
1992, 358, 160), and fungal infections (Lum, R. T. PCT Int. Appl., WO 9805335 A1 980212).
The VEGF-R2 kinase is a receptor tyrosine kinase found in endothelial cells and is involved in angiogenesis—the growth and proliferation of blood vessels from existing capillaries. Angiogenesis plays an important role in development, homeostasis, wound healing, the female reproductive cycle, and in pathological conditions such as rheumatoid arthritis, diabetic retinopathy, macular degeneration, psoriasis and cancer. VEGF-R2 kinase transmits the signal initiated by binding of Vascular Endothelial Growth Factor (VEGF) to the extracellular receptor. Signal transmission to the cell interior is accomplished via tyrosine phosphorylation by VEGF-R2, which prompts proliferation of endothelial cells and the release of cytokines and other cellular processes that result in the growth of new blood vessels. Angiogenesis is critical to the growth of cancerous tumors. Solid tumors will not grow beyond 1-2 mm in size without the support of additional vascularization. Most tumor types, if not all, secrete VEGF in order to stimulate angiogenesis. Inhibition of VEGF-R2 kinase would therefore interrupt a critical process involved in tumor growth and metastasis as well as other pathologic angiogenic conditions.
