Ponatinib is a potent, orally available multi-targeted kinase inhibitor with IC50 of 0.37 nM, 1.1 nM, 1.5 nM, 2.2 nM, and 5.4 nM for Abl, PDGFRα, VEGFR2, FGFR1, and Src, respectively.Ponatinib (AP24534) potently inhibits native ABL (IC50: 0.37 nM), ABLT315I (IC50: 2.0 nM), and other clinically important ABL kinase domain mutants (IC50: 0.30-0.44 nM). Ponatinib also inhibits SRC (IC50: 5.4 nM) and members of the VEGFR, FGFR, and PDGFR families of receptor tyrosine kinases. Ponatinib potently inhibits proliferation of Ba/F3 cells expressing native BCR-ABL (IC50: 0.5 nM). All BCR-ABL mutants tested remained sensitive to Ponatinib (IC50: 0.5-36 nM) including BCR-ABLT315I (IC50: 11 nM). Ponatinib (AP24534) inhibits the in vitro kinase activity of FLT3, KIT, FGFR1, and PDGFRα with IC50 values of 13, 13, 2, and 1 nM, respectively. Ponatinib inhibits phosphorylation of all 4 RTKs in a dose-dependent manner, with IC50 values between 0.3 to 20 nM. Consistent with these activated receptors being important in driving leukemogenesis Ponatinib also potently inhibits the viability of all 4 cell lines with IC50 values of 0.5 to 17 nM. In contrast, the IC50 for inhibition of RS4;11 cells which express native (unmutated) FLT3, is more than 100 nM.
