Abstract:
INTRODUCTION:Angiogenesis is an important component of certain normal physiological processes, but aberrant angiogenesis contributes to some pathological disorders and in particular to tumor growth. Activation of vascular endothelial growth factor receptor-2 (VEGFR-2) by vascular endothelial growth factor (VEGF) is a critical step in the signal transduction pathway that initiates tumor angiogenesis. Inhibition of angiogenesis via blocking VEGF/VEGFR-2 signaling pathway has emerged as a potential approach to anticancer therapy. Indeed, this approach has recently been clinically validated with the approvals of VEGFR-2 inhibitors. Areas covered: This review accounts for small-molecule inhibitors and antibodies of VEGFR-2 reported in the patent literature covering between January 2012 and June 2016, and their potential use as therapeutics for cancers, angiogenesis-related disorders and inflammatory diseases. Expert opinion: Despite the attractiveness of anti-angiogenic therapy by VEGF inhibition alone, several issues may limit this approach. VEGF expression levels can be elevated by numerous diverse stimuli such as the activation of other RTK signaling transduction pathway. Therefore, the development of multi-targeted tyrosine kinase inhibitors and the strategy of using these agents in conjunction with other anti-cancer agents are recent interesting therapeutic approaches that could give promising results.
