A series of 4-(2-fluorophenoxy)quinoline derivatives containing an imidazolone moiety were designed, synthesized and evaluated for their in vitro biological activities against c-Met kinase and four cancer cell lines (A549, H460, HT-29 and MKN-45). Most compounds showed moderate to excellent activities in enzyme and cellular assays. The most promising analog, 58 (c-Met IC50 = 1.42 nM), displayed 2.1-, 8.6-fold increase against H460, and MKN-45 cell lines, respectively, compared with foretinib. An analysis of structure-activity relationships revealed that an ortho substituted phenyl ring as well as an N-unsubstituted imidazolone linker is favorable for antitumor activity.
