GZD-824 is an orally available inhibitor of a broad spectrum of Bcr/Abl tyrosine kinase mutants including T315I (IC50s = 0.34 and 0.68 nM for wild-type Bcr/Abl and Bcr/AblT315I, respectively).1 It has been shown to suppress the proliferation of Bcr/Abl-positive K562 and Ku812 human chronic myelogenous leukemia cells (IC50s = 0.2 and 0.13 nM, respectively) and induce tumor regression in mouse xenograft tumor models driven by either wild-type or mutant Bcr/Abl.1
