Abstract: Aberrant c-Met activation has been implicated in multiple tumor oncogenic processes and drug resistance. In this study, a series of imidazo[4,5-b]pyrazine derivatives was designed and synthesized, and their inhibitory activities were evaluated in vitro. Structure-activity relationship (SAR) was investigated systematically and docking analysis was performed to elucidate the binding mode, leading to the identification of the most promising compound 1D-2 which exhibited significant inhibitory effect on both enzymatic (IC50=1.45nM) and cellular (IC50=24.7nM in H1993 cell line) assays, as well as exquisite selectivity and satisfactory metabolic stability in human and rat liver microsomes.
