The antiproliferative activities of the prepared compounds against representative human neoplastic cell lines were evaluated by MTF assay. The results showed that most of them inhibited cell proliferation in a submicromolar to rnicromolar range. These compounds were also evaluated against KBv200 and MCF-7/Adr cell lines, which overexpress the MDR/P-glycoprotein drug efflux pump responsible for drug resistance, and had a more potential for resisting MDR than their lead compound APO.展开更多
