In vitro cytotoxicity evaluation showed that these compounds exhibited high activity against the selected tumor cells. Among them, compound 9 owned the best potential, its IC50 values being 5.95μmol/L （mononuclear tumor cell line （U937）） and 5.58 μmol/L （cervical cancer cell （HeLa））. Fluorescence and UV-vis studies showed that compound 9 could bind into the minor groove of DNA.展开更多
