Description

CP-547632 is a potent inhibitor of the VEGFR2 and FGF2 kinases with IC50s of 11 and 9 nM, respectively.

Target

IC50: 11 nM (VEGFR2), 9 nM (FGF2)[1]

In Vitro

CP-547632 is an ATP-competitive kinase inhibitor that blocks VEGFR-2 kinase autophosphorylation (IC50=11 nM) and VEGF-induced VEGFR-2 phosphorylation in VEGFR-2-transfected endothelial cells (IC50=6 nM). CP-547632 is approximately equipotent (i.e., <10-fold selective) against VEGFR-2, bFGF receptor, and EGFR/Tie-2 chimera, the receptor for Angiopoietin[1].

In Vivo

CP-547632 inhibits tumor-associated VEGFR-2 phosphorylation resulting in decreased microvascular density and significant tumor growth inhibition in a number of tumor models (EC50=590 ng/mL). CP-547632 is shown to inhibit VEGF-induced angiogenesis in vivo in a dose-responsive fashion[1].

Cell Assay

Porcine aortic endothelial cells stably expressing full-length VEGFR-2 have been used. CP-547632 is added to serum-deprived cells and incubated at 37°C, 5% for 1 h. The cells are then stimulated with 500 ng/mL VEGF. Whole cell lysates are then immunoprecipitated using anti-VEGFR-2, and Western blot analysis is carried out with antibodies recognizing either the protein or PY (A) [1].

Animal Admin

Mice[1] MDA-MB-231 cells are injected s.c into the flank of BALB/c male mice. Animals bearing tumors of 75-150 mm3 each are treated with CP-547632 (6.25-100 mg/kg, p.o., qd) in 5% Gelucire. The tumors are measured with calipers, and the tumor volumes are calculated[1].
