Discovery of [1,2,4]triazolo[3,4-b][1,3,4]thiadiazole derivatives as novel, potent and selective c-Met kinase inhibitors: Synthesis, SAR study, and biological activity
A series of [1,2,4]triazolo[3,4-b][1,3,4]thiadiazole derivatives were designed, synthesized and evaluated for their biologicalactivity. Most of these compounds showed potent activities against c-Met kinase and cell growth inhibition. The most promising compound, 7d, has the IC50 values of 2.02 and 88 nM to inhibit c-Met kinase activity and cell growth in the MKN45 cell line, respectively. In addition
