A new series of Schizandrin (1) derivatives were synthesized utilizing the C-9 position of the Schizandrin core and evaluated for their cytotoxic activities against HeLa (cervical cancer), A549 (lung cancer), MCF-7 (breast cancer) and DU-145 (prostate cancer) cell lines. Among the synthesized series, 4e, 4f, 4g and 5 showed potent activities against tested cell lines. More significantly, compound 5
利用五味子素核心的C-9位置合成了新的五味子素系列(1)衍生物,并评估了其对HeLa(子宫颈癌),A549(肺癌),MCF-7(乳腺癌)和DU- 145(前列腺癌)细胞系。在合成的系列中,4e,4f,4g和5显示出对测试细胞系的有效活性。更重要的是,化合物5对DU-145表现出最强的细胞毒活性,IC 50值为1.38μM,与标准药物阿霉素相当。此外,流式细胞仪分析表明5将细胞停滞在G2 / M期,从而导致细胞凋亡。分子对接分析表明5个占据了微管蛋白的秋水仙碱结合口袋。总体而言,本研究表明5作为有丝分裂剂。
