MedKoo CAT#: 203110

CAS#: 212141-51-0

Description: Vatalanib, also known as PTK787, is an orally bioavailable anilinophthalazine with potential antineoplastic activity. Vatalanib binds to and inhibits the protein kinase domain of vascular endothelial growth factor receptors 1 and 2; both receptor tyrosine kinases are involved in angiogenesis. This agent also binds to and inhibits related receptor tyrosine kinases, including platelet-derived growth factor (PDGF) receptor, c-Kit, and c-Fms.
