OBJECTIVE: To synthesize a novel chalcone-1,3,4-thiadiazole hybrid and investigate its anticancer effects against NCI-H460 cells.
METHODS: (E)-3-(4-bromophenyl)-1-(4-hydroxyphenyl)prop-2-en-1-one, 1,3-dibromopropane and 1,3,4-thiadiazole-2-thiol were used as chemical materials to synthesize compound ZW97. The NCI-H460 lung cancer cell line was selected to explore the antitumor effects of compound ZW97 in vitro and in vivo.
RESULTS: Compound ZW97 selectively inhibited cell proliferation against lung cancer cell lines NCI-H460, HCC-44 and NCI-H3122 with IC50 values of 0.15 μM, 2.06 μM and 1.17 μM, respectively. ZW97 suppressed migration and the epithelial-mesenchymal transition process in NCI-H460 cells in a concentration-dependent manner. Based on the kinase activity results and docking analysis, compound ZW97 is a novel tyrosine-protein kinase Met (c-Met kinase) inhibitor. It also inhibited NCI-H460 cell growth in xenograft models without obvious toxicity to normal tissues.
CONCLUSIONS: Compound ZW97 is a potential c-Met inhibitor that might be a promising agent to treat lung cancer by inhibiting the epithelial-mesenchymal transition process.
