Mechanism of Action

Targets/IC₅₀/Ki	VEGFR2/KDR (Cell-free assay) 37 nM VEGFR1/FLT1 (Cell-free assay) 77 nM VEGFR2/Flk1 (Cell-free assay) 270 nM PDGFRβ (Cell-free assay) 580 nM VEGFR3/FLT4 (Cell-free assay) 660 nM c-Kit (Cell-free assay) 730 nM c-Fms (Cell-free assay) 1.4 μM
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.
Kinase Assay	VEGF Receptor Tyrosine Kinase Assays
Kinase Assay	The in vitro kinase assays are performed in 96-well plates as a filter binding assay, using the recombinant GST-fused kinase domains expressed in baculovirus and purified over glutathione-Sepharose. γ-[³³P]ATP is used as the phosphate donor, and poly-(Glu:Tyr 4:1) peptide is used as the acceptor. Recombinant GST-fusion proteins are diluted in 20 mM Tris·HCl (pH 7.5) containing 1–3 mM MnCl₂, 3–10 mM MgCl₂, 0.25 mg/mL polyethylene glycol 20000, and 1 mM DTT, according to their specific activity. Each GST-fused kinase is incubated under optimized buffer conditions [20 mM Tris-HCl buffer (pH 7.5), 1–3 mM MnCl₂, 3–10 mM MgCl₂, 3–8 μg/mL poly-(Glu:Tyr 4:1), 0.25 mg/mL polyethylene glycol 20000, 8 μM ATP, 10 μM sodium vanadate, 1 mM DTT, and 0.2 μCi[γ-₃₃P]ATP in a total volume of 30 μL in the presence or absence of a test substance for 10 minutes at ambient temperature. The reaction is stopped by adding 10 μL of 250 mM EDTA. Using a 96-well filter system, half the volume (20 μL) is transferred onto a Immobilon-polyvinylidene difluoride membrane. The membrane is then washed extensively in 0.5% H₃PO₄ and then soaked in ethanol. After drying, Microscint cocktail is added, and scintillation counting is performed. IC50s for PTK787/ZK 222584 or SU5416 in these as well as all assays described below are calculated by linear regression analysis of the percentage inhibition.
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.
