The present study reports the synthesis and anticancer activity evaluation of twelve novel silybin analogues designed using a ring disjunctive-based natural product lead (RDNPL) optimization approach. All twelve compounds were tested against a panel of cancer cells (i.e. breast, prostate, pancreatic, and ovarian) and compared with normal cells. While all of the compounds had significantly greater efficacy
本研究报告了十二种新型水飞蓟宾类似物的合成和抗癌活性评估,这些类似物是使用基于环分离剂的天然产物铅(RDNPL)优化方法设计的。所有十二种化合物均针对一组癌细胞(即乳腺癌,前列腺癌,胰腺癌和卵巢癌)进行了测试,并与正常细胞进行了比较。尽管所有化合物的功效均显着高于水飞蓟宾,但与正常细胞相比,发现衍生物15k具有很高的效力(IC50 <1μM),并且对卵巢癌细胞系以及其他癌细胞系具有选择性。初步的机理研究表明,15k的抗增殖功效是由其诱导细胞凋亡,线粒体膜电位的丧失以及在G1期以下的细胞周期停滞介导的。此外,15k通过与微管蛋白结合并抑制其表达和功能来抑制细胞微管的动态和组装。总体而言,研究结果确定15k是一种新型微管蛋白抑制剂,对卵巢癌细胞具有显着活性。
