Abstract A series of litseaone B analogues 4a∼4p were synthesised and antitumor activities of all compounds were screened. These compounds were designed by introducing different substituents on the B ring. Among these synthesised compounds, it was proved that 4k showed excellent activity against A549, HepG2, and HCT-15 cell lines, the IC50 values were 7.60 μM, 20.53 μM, and 4.59 μM, respectively. The
摘要 合成了一系列litseaone B类似物4a∼4p,并筛选了所有化合物的抗肿瘤活性。这些化合物是通过在 B 环上引入不同的取代基来设计的。在这些合成的化合物中,证明4k对A549、HepG2和HCT-15细胞系表现出优异的活性,IC 50值分别为7.60 μM、20.53 μM和4.59 μM。微管蛋白聚合抑制和免疫荧光染色实验结果表明4k可以作用于微管蛋白并抑制微管蛋白的聚合。此外,伤口愈合试验表明,4k可以以剂量依赖性方式抑制A549细胞的迁移。此外,流式细胞仪的结果显示,4k能够阻断 G2/M 期的细胞周期,诱导线粒体膜电位降低,最终导致 A549 细胞凋亡。重要的是,可能的结合模型也是通过分子对接进行的。学科分类代码:短通信。
