Moreover, the tubulin polymerization experiments indicated that compound 6e could inhibit the tubulin polymerization. Immunofluorescence study and cell cycle analysis clearly revealed compound 6e could disrupt intracellular microtubule organization, arrest cell cycle at the G2/M phase. In addition, molecular docking analysis demonstrated the interaction of compound 6e at the colchicine-binding site of tubulin
设计了一系列以1,2,4-三唑为氢键受体的新型5-甲基-4-芳基-3-(4-芳基哌嗪-1-羰基)-4 H -1,2,4-三唑合成并评估了它们的抗增殖和微管蛋白聚合抑制活性。它们中的一些在体外对三种癌细胞系(包括SGC-7901,A549和HeLa)表现出中等活性。化合物6e对三种癌细胞表现出最高的效力。此外,微管蛋白聚合实验表明化合物6e可以抑制微管蛋白聚合。免疫荧光研究和细胞周期分析清楚地表明了化合物6e可能破坏细胞内微管组织,使细胞周期停滞在G2 / M期。另外,分子对接分析表明化合物6e在微管蛋白的秋水仙碱结合位点相互作用。这些初步结果表明,化合物6e是一种新型秋水仙碱结合位点抑制剂,值得进一步研究。
