hormone dependent MCF-7, triple negative MDA-MB-231 breast cancer cell lines and primary breast cancer cells. The cytotoxicity of these compounds (represented as IC50 concentration) ranges between 4.04 and 33.93 μM against breast cancer cells without affecting normal cells (IC50 value > 952 μM). All the compounds (7–11) perturbed the cell cycle progression at G2/M phase and triggered apoptosis. Among all
我们提出了 N-咪唑吡啶-noscapinoids,一类新的 noscapine 衍生物,它与微管蛋白结合并表现出对三阳性 (MCF-7) 和三阴性 (MDA-MB-231) 乳腺癌细胞的抗增殖活性。诺斯卡平支架的异喹啉环的 N 原子通过偶联咪唑在计算机中发生改变 [(Ye et al., 1998;Ke等人,2000) 1,21,2-a] 吡啶药效团合理开发一系列具有高微管蛋白结合亲和力的 N-咪唑吡啶-noscapinoid (7-11)。N-咪唑吡啶-noscapinoids 7-11 的预测 ΔG 结合在 -27.45 至 -36.15 kcal/mol 之间变化,远低于具有 ΔG 结合的 noscapine 的值 -22.49 kcal/mol。使用激素依赖性 MCF-7 、三阴性 MDA-MB-231 乳腺癌细胞系和原发性乳腺癌细胞评估 N-咪唑吡啶-noscapinoids 的细胞毒性。这些化合物的细胞毒性(以
