A systematic structure–activity relationship study of the potent anticancer marine macrolide biselyngbyolide B has been accomplished. A total of 11 structural variants of the parent natural product, of which 2 are natural analogues, have been studied against a human colorectal carcinoma cell line. The requisite functional units of the parent molecule responsible for the cytotoxic activities have been
已经完成了强效抗癌海洋大环内酯双色内酯 B 的系统构效关系研究。已经针对人结直肠癌细胞系研究了母体天然产物的总共 11 种结构变体,其中 2 种是天然类似物。负责细胞毒活性的母体分子必需的功能单元已被公开。 Biselyngbyolide C是biselyngbyolide B的天然类似物之一,人们对其分子机制进行了深入研究。有趣的是,体外数据表明,动力相关蛋白 1 介导的线粒体裂变和活性氧产生的诱导,导致结肠癌细胞中 ASK1/P38/JNK 介导的细胞凋亡的激活,这是双色内酯 B 介导的重要途径细胞毒性。值得注意的是,这项研究揭示了大环内酯参与线粒体裂变,促进癌细胞凋亡,提供了新的见解。
