Six series of novel 4-(2-fluorophenoxy)-3,3'-bipyridine derivatives conjugated with aza-aryl formamide/amine scaffords were designed and synthesized through a structure-based molecular hybridization approach. The target compounds were evaluated for c-Met kinase inhibitory activities and cytotoxicity against four cancer cell lines (HT-29, A549, MKN-45 and MDA-MB-231) in vitro. Most compounds exhibited moderate to excellent potency, and the most promising candidate 26c (c-Met kinase IC50 = 8.2 nM) showed a 4.7-fold increase in cytotoxicity against c-Met-addicted MKN-45 cell line in vitro (IC50 = 3 nM), superior to that of Foretinib (IC50 = 23 nM). The preliminary structure-activity relationship indicated that a 1H-benzo [e] [1,3,4]thiadiazine-3-carboxamide-4,4-dioxide moiety as linker contributed to the antitumor potency.
