摘要
A series of 4-(2-fluorophenoxy)quinoline derivatives bearing the 4-oxo-1,4-dihydroquinoline-3-carboxamide moiety were designed, synthesized, and evaluated for their in vitro antitumor activity against the H460, HT-29, MKN-45, U87MG, and SMMC-7721 cancer cell lines. Most of the tested compounds showed potent activity and high selectivity toward the HT-29 and MKN-45 cell lines. Furthermore, compounds 21b, 21c, and 21i were further examined for their c-Met kinase activity and exhibited strong efficacy with IC50 values in the single-digit nanomolar range, which was comparable with the positive control foretinib. The most promising compound 21c showed excellent cytostatic activity with IC50 values from 0.01 to 0.53 mu M against all tested cell lines, thus being 1.7-2.2 times more active than foretinib.
