present study, two new series of pyrrolizines bearing 3,4,5-trimethoxyphenyl moiety were designed, synthesised, and evaluated for their cytotoxic activity. The benzamide derivatives 16a–e showed higher cytotoxicity than their corresponding Schiff bases 15a–e. Compounds 16a,b,d also inhibited the growth of MCF-7/ADR cells with IC50 in the range of 0.52–6.26 μM. Interestingly, the new compounds were less
摘要 在本研究中,设计、合成了两个新系列的带有 3,4,5-三甲氧基苯基部分的吡咯嗪,并评估了它们的细胞毒活性。苯甲酰胺衍生物16a-e显示出比其相应的希夫碱15a-e更高的细胞毒性。化合物16a、b、d也抑制 MCF-7/ADR 细胞的生长,IC 50范围为 0.52–6.26 μM。有趣的是,新化合物对正常 MRC-5 细胞的细胞毒性较小(IC 50 = 0.155–17.08 μM)。机理研究揭示了化合物16a , b , d的能力抑制微管蛋白聚合和多种致癌激酶。此外,化合物16a、b、d在MCF-7细胞中诱导preG 1和G 2 /M细胞周期停滞和早期凋亡。与共结晶配体相比,化合物16a、b、d进入微管蛋白、CDK-2 和 EGFR 蛋白中的活性位点的分子对接分析显示出更高的结合亲和力。这些初步结果表明,化合物16a、b、d可以作为有前景的先导化合物,用于未来开发新的强效抗癌剂。 强调
