Vandetanib hydrochloride (formerly also known as ZD6474) is a novel, highly potent, orally bioavailable, selective inhibitor of VEGFR2 with IC50 of 40 nM in a cell-free assay. Vandetanib selectively inhibits the tyrosine kinase activity of vascular endothelial growth factor receptor 2 (VEGF2), thereby blocking VEGF-stimulated endothelial cell proliferation and migration and reducing tumor vessel permeability. The inhibition of VEGFR-2 was 2.7-fold more potent than that of VEGFR-3 (Flt-4) kinase and 40-fold more potent than that of VEGFR-1. In human umbilical vein endothelial cells, treatment of ZD6474 resulted in significant inhibition of cell proliferation stimulated by VEGF and EGF with IC50 values of 60 and 170 nM, respectively.
