77 ± 0.36 and 3.83 ± 0.26 µM, respectively. Further mechanism study shown that 5i potently inhibited tubulin polymerization, induced cell cycle arrest at G2/M phase and cell apoptosis in MCF-7 cell line. Furthermore, molecular modeling study suggested that 5i probably binds to the colchicine site of tubulin. Graphical Abstract Fullsize Image
设计,合成并评估了一系列新颖的4-(4-甲氧基萘-1-基)-5-芳基嘧啶-2-胺类化合物的抗癌活性。与标准药物顺铂相比,大多数合成的化合物均表现出中等至高的抗增殖活性。其中,发现在苯基的4位带有乙氧基的5i在MCF-7和HepG2癌细胞系中活性最高,IC 50值分别为3.77±0.36和3.83±0.26 µM。进一步的机理研究表明,5i有效抑制微管蛋白聚合,诱导细胞周期停滞在G2 / M期以及MCF-7细胞株的细胞凋亡。此外,分子建模研究表明5i 可能与微管蛋白的秋水仙碱位点结合。 图形抽象全尺寸图像
