Abstract:

Thirteen novel 4-phenoxyquinoline derivatives bearing semicarbazone moiety were successfully designed and synthesized based on the structural characteristics of 4-phenoxyquinoline small molecule type II c-Met kinase inhibitors. The in vitro inhibitory activities of all the target compounds against c-Met kinase were evaluated using mobility shift assay. The in vitro antiproliferative activities of the target compounds against A549, PC-3, AGS and MKN45 cells were evaluated using MTT-based assay. Most of the target compounds showed excellent inhibitory activities against c-Met kinase and all the tested cancer cell lines. Among them, compounds 6f(c-Met: IC50=14.50 nmol/L) and 6k(c-Met: IC50=15.68 nmol/L) exhibited excellent inhibition activity of against c-Met kinase. The IC50 values of 6f for A549, PC-3, AGS and MKN-45 cells were 0.93, 7.81, 12.88, and 2.58 μmol/L, respectively. The IC50 values of 6k for A549, PC-3, AGS and MKN45 cells were 0.67, 6.60, 3.04, and 0.88 μmol/L, respectively. Further studies on the anti-tumor mechanism indicated that compound 6k induced MKN45 and A549 cells apoptosis, and inhibited the migration ability of MKN45 and A549 cells.
