CP-673451 efficiently suppresses the PDGFR downstream signaling pathway. It inhibits phosphorylation of Akt, GSK-3β, p70S6, and S6 in A549 cells in a concentration-dependent manner. CP-673451 (0.0625-4 μM) significantly reduces the viability of NSCLC cell lines A549 and H1299 in a time- and concentration-dependent manner, with IC50s of 0.49 and 0.61 μM, respectively. CP-673451 (1, 4 μM) induces apoptosis in non-small-cell lung cancer cells. CP-673451 (25, 100, or 400 nM) is effective at inhibiting migration and invasion of NSCLC cells by suppression of lamellipodia formation. CP-673451 and crenolanib show selective lethality toward cells with CA. U2OS cells treated with 1 to 4 μM CP-673451 or crenolanib show a ruffled cell surface as a sign for alterations of the cortical actin cytoskeleton. CP-673451 attenuates PDGF-BB-induced signaling, and significantly enhances

CP-673451 (20 mg/kg) leads to a medium suppression of tumor growth, while high-dose CP-673451 (40 mg/kg) strongly inhibits tumor growth in mice without significant weitht loss. CP-673,451 (10, 33, and 100 mg/kg, p.o., b.i.d) inhibits the growth of Colo205 tumor in a dose-dependent manner, and similar tumor growth inhibition experiments completes on LS174T, H460, and U87MG xenografts, with no signs of morbidity or weight loss. has not independently confirmed the accuracy of these methods. They are for reference only.
