  Design and synthesis of 2-phenylnaphthalenoids and 2-phenylbenzofuranoids as DNA topoisomerase inhibitors and antitumor agents

  摘要：

  Eight 2-phenylnaphthalenoids (2PNs) (3a h) and twenty four 2-phenylbenzofuranoids (2PBF5) (4a-4j, 5a-5j, 6a, 6f-6h) were successfully designed, synthesized and their antiproliferative and in vitro DNA topoisomerase inhibitory activities were evaluated. Nine compounds (four 2PNs and five 2PBFs) showed either Topol or TopoII alpha inhibitory activities. Six compounds (four 2PNs and two 2PBFs) exhibited potent cytotoxicity with IC50 values for 72 h exposure ranging from 0.3 to above 20 mu M against MDA-MB-231, MDA-MB-435, HepG2 and PC3 cell lines. The two 2PBFs displayed comparable and even better antiproliferative as well as TopoII alpha inhibitory activities than 2PNs. Interestingly, the active 2PBFs displayed different mechanisms of TopoII alpha inhibition from that of 2PNs, suggesting that the chromophore scaffold replacement may result in a change of the binding site of inhibitors to TopoII alpha. Furthermore, the mechanisms of antiproliferation on MDA-MB-231 cells indicate that compounds 5a and 5f are promising for further development of anticancer agents. The results of this study reveal that the evolutionary strategy of medicinal chemistry through scaffold hopping is a promising strategy for structure optimization of TopoII alpha inhibitors.
