Abstract

The discovery of a novel potent type II ABL/c-Kit dual kinase inhibitor compound 34 (CHMFL-ABL/KIT-155), which utilized a hydrogen bond formed by NH on the kinase backbone and carbonyl oxygen of 34 as a unique hinge binding, is described. 34 potently inhibited purified ABL (IC50: 46 nM) and c-Kit kinase (IC50: 75 nM) in the biochemical assays and displayed high selectivity (S Score (1) = 0.03) at the concentration of 1 μM among 468 kinases/mutants in KINOMEscan assay. It exhibited strong antiproliferative activities against Bcr-Abl/c-Kit driven CML/GISTs Cancer cell lines through blockage of the Bcr-Abl/c-Kit mediated signaling pathways, arresting cell cycle progression and induction of Apoptosis. 34 possessed a good oral PK property and effectively suppressed the tumor progression in the K562 (CML) and GIST-T1 (GISTs) cells mediated xenograft mouse model. The distinct hinge-binding mode of 34 provided a novel pharmacophore for expanding the chemical structure diversity for the type II kinase inhibitors discovery.
