Vatalanib dihydrochloride (PTK787 dihydrochloride) 是VEGFR2/KDR的抑制剂,其IC50值为37nM。
Information
Vatalanib 2HCl (PTK787, ZK 222584, cpg-79787) is an inhibitor ofVEGFR2/KDRwithIC50of 37 nM in a cell-free assay, less potent against VEGFR1/Flt-1, 18-fold against VEGFR3/Flt-4. Phase 3.
In vitro
Vatalanib also inhibits Flk, c-Kit and PDGFRβ with IC50 of 270 nM, 730 nM and 580 nM, respectively. Furthermore, Vatalanib shows the anti-proliferation effect by inhibiting thymidine incorporation induced by VEGF in HUVECs with and IC50 of 7.1 nM, and dose-dependently suppresses VEGF-induced survival and migration of endothelial cells in the same dose range without cytotoxic or antiproliferative effect on cells that do not express VEGF receptors. A recent study shows that Vatalanib significantly inhibits the growth of hepatocellular carcinoma cells and enhances the IFN/5-FU induced apoptosis by increasing proteins levels of Bax and reduced Bcl-xL and Bcl-2.
In vivo
Vatalanib induces dose-dependent inhibition of the angiogenic response to VEGF and PDGF in both a growth factor implant model and a tumor cell-driven angiogenesis model after once-daily oral dosing (25-100 mg/kg). In the same dose range, Vatalanib also inhibits the growth and metastasesof several human carcinomas in nude mice without significant effect on circulating blood cells or bone marrow leukocytes.
