ATP-competitive, potent and selective platelet-derived growth factor receptor (PDGFR) inhibitor against tumor growths in vivo.
CP-673451 is an ATP-competitive, potent and selective platelet-derived growth factor receptor inhibitor (PDGFR1 (β)/PDGFR2 (α) IC50 = 1/10 nM with 10 μM ATP; IC50 = 252 nM/c-kit, 450 nM/VEGFR-1/2; >450-fold reduced potency toward other angiogenic receptors and non-receptor kinases). CP-673451 potently inhibits PDGF-BB-induced receptor phosphorylation (IC50 = 6.4 nM; PDGFR1 transfectant) and effectively suppress human cancer xenografts-derived tumor in mice in vivo (ED50 ≤33 mg/kg via b.i.d. or q.d. p.o.) by inhibiting PDGFR phosphorylation and angiogenesis in tumor tissues.
