Design, synthesis, and antiproliferative activity of novel 1,2,4-triazole-chalcone compounds

A series of novel 1,2,4-triazole-chalcone compounds 10a-10s were designed by molecular hybridization strategy and synthesized. The molecular structures of the novel chalcones were characterized by H-1-NMR, C-13-NMR, and HRMS. The anti-proliferative activities of the novel chalcones against four cancer cell lines in vitro were examined by MTT, four tumor cell lines including human colon cancer cell SW620, human non-small cell lung cancer cell A549, human cervical cancer cell HeLa, and human breast cancer cell MCF-7. Compound 10o showed certain selectivity to SW620 cell line, and its IC50 value was 21.55 mu M. 10q had good anti-proliferative activity against A549 cells with an IC50 value of 25.58 mu M.
