Abstract

A series of 6,7-disubstituted-4-phenoxyquinoline derivatives bearing the 1,8-naphthyridin-2-one moiety were designed, synthesized and evaluated for their biological activities. The target compounds exhibited moderate to high antiproliferative activity against three Cancer cell lines (A549, HepG2 and MCF-7) and several compounds (25, 27, 33, 37, 41, 43, 49 and 53) were evaluated for the activity against c-Met kinase. The most promising compound 33 (IC50 c-Met = 2.36 nM) showed excellent activity against A549, HepG2 and MCF-7 cell lines with IC50 values of 0.23 μM, 0.42 μM and 0.21 μM, respectively, which was 1.5-2.1 times of the positive control. Furthermore, compound 33 was evaluated for the activity against FLT3, PDGFR-α, PDGFR-β, c-Kit, Flt4, ALK and EGFR kinase. Structure activity relationship studies indicated that mono-EWGs (such as R2 = F) at 4-position of moiety C was a key factor in improving the antitumor activity. In addition, further research on compound 33 was mainly including concentration dependence, Apoptosis (acridine orange staining), Apoptosis result analyzing and molecular docking.
