A series of phenstatin/isocombretastatin-oxindole conjugates was synthesized and tested for their cytotoxic activity against five human cancer cells such as prostate (DU-145), lung (A549), colon (HT-29), breast (MCF-7), liver (HepG2) cancer cells with IC50 values ranging from 0.049 to 38.90 μM. Amongst them, two conjugates (5c and 5d) showed broad spectrum of antiproliferative efficacy on lung cancer
合成了一系列的phenstatin / isocombretastatin-oxindole偶联物,并测试了它们对五种人类癌细胞(如前列腺(DU-145),肺(A549),结肠(HT-29),乳腺癌(MCF-7),肝(HepG2)癌细胞,IC 50值范围为0.049至38.90μM。其中,两种结合物(5c和5d)对IC 50值分别为79 nM和93 nM的肺癌细胞显示出广谱的抗增殖功效,而对IC 50值分别为45 nM和49 nM的结肠癌细胞显示出抗增殖作用,分别。另外,细胞周期分析显示这些结合物(5c和5d)停在G 2上。/ M期并导致凋亡细胞死亡,这被膜联蛋白V-FITC和线粒体膜去极化证实。此外,微管蛋白聚合测定分析结果表明,这些缀合物,特别是5c和5d,对微管蛋白组件表现出显着的抑制作用,其IC 50值分别为1.23μM和1.01μM。分子对接研究表明,这些化合物(5c和5d)占据了微管蛋白的秋水仙碱结合位点。
