Abstract

Protoapigenone (1), isolated from Thelypteris torresiana, previously showed significant cytotoxic activity against five human cancer cell lines. In a continued structure-activity relationship study, the first total synthesis and modification of 1 were achieved. All synthesized compounds and related intermediates were evaluated for cytotoxic activity against five human cancer cell lines, HepG2, Hep3B, MDA-MB-231, MCF-7, and A549. Among them, 24 showed 2.2-14.2-fold greater cytotoxicity than 1 and naphthyl A-ring analogues remarkably enhanced the activity.

摘要

从华南针毛蕨中分离得到的原芹菜素(1),此前已显示出对五种人类癌细胞系具有显著的细胞毒性活性。在一项持续的构效关系研究中,实现了1的首次全合成及修饰。对所有合成化合物和相关中间体针对五种人类癌细胞系HepG2、Hep3B、MDA-MB-231、MCF-7和A549进行了细胞毒性活性评估。其中,24表现出比1高2.2至14.2倍的细胞毒性,且萘基A环类似物显著增强了活性。
