摘要

Human DNA Topoisomerase II alpha (Topo II alpha) is one of the important therapeutic targets for the treatment of cancers. Our previous study showed that p-terphenyls have inhibitory effects on Topo II alpha and inhibit the proliferation of human breast ductal carcinoma cells. In this study, nineteen 6-substituted aryl-2-methoxyquinolines (3a similar to 3s) were designed, synthesized and evaluated for their cytotoxicity against the growth of human triple negative breast cancer MDA-MB-231 cell line and inhibitory activity against Topo II alpha. Among these compounds, 6-(4-(hydroxymethyl)phenyl)-2-methoxyquinoline (3b) showed the most potent activity (IC50 = 9.9 mu mol.L-1). These results have important significance for the further study of aryl quinoline TopoII alpha inhibitors.
