Potent multi-kinase and pan-BCR-ABL inhibitor. Displays potent activity against cell lines expressing native BCR-ABL or BCR-ABLT3151 (IC50 values are 0.37 and 2.0 nM respectively); also inhibits other ABL kinase domain mutants at nanomolar potencies. Exhibits inhibitory activity against PDGFRα, c-Src and c-Kit (IC50 values are 1.1, 5.4 and 12.5 nM respectively); potently inhibits FGFR and VEGFR family kinases. Orally active.
