Twelve new aryl-substituted naphthalenoids (1-7, 9, 10, and 13-16) together with four known ones (8, and 11-
13) have been designed and synthesized. Their antitumor activities were evaluated by sulforhodamine B assay on human
breast cancer MDA-MB-231, human lung cancer A549 and human cervical cancer HeLa cell lines. Four compounds (2, 4,
10 and 12) showed potent inhibitory activities against the growth of the three cell lines with IC50 between 0.34-3.49 µM,
and were more potent than the reference etoposide (IC50 3.67-13.78 µM). DNA relaxation assay revealed that compound 2
showed potent inhibitory activity against Topo IIα in vitro. The structure-activity relationships of these compounds were
discussed, suggesting that further structural optimizations of aryl-substituted naphthalenoids could lead to the discovery of
potent antitumor agents targeting topoisomerases.
我们设计并合成了十二种新的芳基取代萘类化合物(1-7、9、10 和 13-16)以及四种已知的萘类化合物(8 和 11-13)。在人乳腺癌 MDA-MB-231、人肺癌 A549 和人宫颈癌 HeLa 细胞系上,通过磺基罗丹明 B 检测法评估了这些化合物的抗肿瘤活性。四种化合物(2、4、10 和 12)对这三种细胞株的生长都有很强的抑制作用,IC50 在 0.34-3.49 µM 之间,比参照物依托泊苷(IC50 为 3.67-13.78 µM)更强。DNA 松弛试验显示,化合物 2 在体外对 Topo IIα 具有很强的抑制活性。对这些化合物的结构-活性关系进行了讨论,表明进一步优化芳基取代的萘类化合物的结构可以发现针对拓扑异构酶的强效抗肿瘤药物。
