Uses
CP-547632 TFA is an orally active, ATP-competitive and potent VEGFR-2 and FGF kinases inhibitor with IC50s of 11 nM and 9 nM, respectively. CP-547632 TFA is selective for VEGFR2 and bFGF over EGFR, PDGFRβ, and related tyrosine kinases (TKs). CP-547632 TFA has antitumor efficacy[1].
in vivo
CP-547632 TFA (p.o.; 6.25-100 mg/kg/day; for 10-24 days) causes a dose-dependent inhibition of growth in Colo-205, DLD-1, and MDA-MB-231 xenografts[1].
CP-547632 TFA (oral; 50 mg/kg; a single oral dose) yieldes plasma concentrations above 500 ng/ml for 12 hours[1].
