Tivozanib (AV-951; KRN951) is a highly potent and selective VEGFR 1/2/3 inhibitor with IC50s of 0.21, 0.16, and 0.24 nM in cell assay, respectively.Tivozanib potently inhibits VEGF-induced VEGFR2 phosphorylation in endothelial cells (IC50=0.16 nM). It also inhibits ligand-induced phosphorylation of PDGFRβ and c-Kit (IC50=1.72 and 1.63 nM, respectively). Tivozanib blocks VEGF-dependent, but not VEGF-independent, activation of mitogenactivated protein kinases and proliferation of endothelial cells. It inhibits VEGF-mediated migration of human umbilical vein endothelial cells[1].Following p.o. administration to athymic rats, Tivozanib decreases the microvessel density within tumor xenografts and attenuates VEGFR-2 phosphorylation levels in tumor endothelium. It also displays antitumor activity against a wide variety of human tumor xenografts, including lung, breast, colon, ovarian, pancreas, and prostate cancer[1].
