targeting a new binding region at the interface between αβ-tubulin heterodimers at the colchicine binding site, we designed a series of 7-substituted 1-methyl-1,4-dihydroindeno[1,2-c]pyrazoles as potential tubulin polymerization inhibitors. Among the compounds synthesized, 2-(6-ethoxy-3-(3-ethoxyphenylamino)-1-methyl-1,4-dihydroindeno[1,2-c]pyrazol-7-yloxy)acetamide 6a and 2-(6-ethoxy-3-(3-ethoxyph
通过在秋水仙碱结合位点的αβ-微管蛋白异二聚体之间的界面处靶向新的结合区域,我们设计了一系列7-取代的1-甲基-1,4-二氢茚并[1,2- c ]吡唑类作为潜在的微管蛋白聚合抑制剂。在合成的化合物中,2-(6-乙氧基-3-(3-乙氧基苯基氨基)-1-甲基-1,4-二氢茚并[1,2 - c ]吡唑-7-酰氧基)乙酰胺6a和2-(6-乙氧基-3-(3-乙氧基苯基氨基)-1-甲基-1,4-二氢茚并[1,2- c ]吡唑-7-酰氧基)-N-羟基乙酰胺6n对HepG2,Hela,PC3和MCF-7癌细胞系。在机理研究中,6a通过与微管蛋白秋水仙碱结合位点结合,抑制A549细胞中的微管蛋白聚合和微管紊乱。6a在G2 / M期阻滞了A549细胞,这与细胞周期蛋白B1和p-cdc2表达的改变有关。6a通过激活caspase-3和PARP诱导A549细胞凋亡。另外,6a以浓度依赖的方式抑制毛细管的形成。在非
