A series of benzimidazole–oxindole conjugates were synthesized and evaluated for their cytotoxic activity. The cytotoxicity assay results suggest that conjugates 5c and 5p exhibit promising cytotoxicity against human breast cancer cell line (MCF-7). The Cell cycle analysis revealed that these conjugates induced cell cycle arrest at G2/M phase in MCF-7 cells. The tubulin polymerization assay results
合成了一系列苯并咪唑-羟吲哚缀合物,并评估了它们的细胞毒性活性。细胞毒性测定结果表明,缀合物5c和5p对人乳腺癌细胞系(MCF-7)显示出有希望的细胞毒性。细胞周期分析表明,这些缀合物诱导了MCF-7细胞在G2 / M期的细胞周期停滞。微管蛋白聚合测定结果表明,这些结合物抑制微管蛋白聚合,IC 50值分别为1.12和1.59μM。免疫荧光分析还表明,这些结合物可有效抑制MCF-7细胞中的微管组装。此外,分子对接研究表明这些缀合物5c和5p与微管蛋白相互作用并有效结合。总体而言,结果表明这些苯并咪唑-羟吲哚共轭物通过抑制微管蛋白聚合而具有细胞毒性。
