Pazopanib-Vista is an orally administered, potent, multi-targeted tyrosine kinase (TK) inhibitor of vascular endothelial growth factor receptors (VEGFR) 1, 2, and 3, platelet-derived growth factor receptors (PDGFR) α and β, and stem cell factor receptor (c-KIT) with IC50s of 10, 30, 47, 71, 84, and 74 nmol/mL, respectively. In preclinical experimental studies, pazopanib dose-dependently inhibited ligand-induced autophosphorylation of VEGFR-2, c-Kit, and PDGFR-β in cells. In in vivo studies, pazopanib inhibited VEGF-induced VEGFR-2 phosphorylation in animal lungs, angiogenesis in animals in various experimental models, and growth of multiple human tumor xenografts in animals.
