active compound, which is more active than the standard drug cisplatin (IC50 = 15.24 ± 1.27 μM). In vitro tubulin polymerization inhibition assay, EBI competition assay, cell cycle analysis, and cell apoptosis assay identified that compound 4u was a new tubulin polymerization inhibitor by targeting the colchicine binding site. Besides, molecular docking study showed that compound 4u has high binding
设计,合成了一系列带有萘部分的二苯甲酮衍生物,通过1 H NMR,13 C NMR和HRMS对其进行了表征,并评估了其对人乳腺癌细胞系(MCF-7)的抗增殖活性。大多数测试的衍生物对MCF-7细胞系表现出良好至中等的细胞毒性。其中,化合物4u(IC 50 = 1.47±0.14μM)是活性最高的化合物,其活性比标准药物顺铂(IC 50 = 15.24±1.27μM)高。体外微管蛋白聚合抑制测定,EBI竞争测定,细胞周期分析和细胞凋亡测定确定化合物4u通过靶向秋水仙碱结合位点是一种新的微管蛋白聚合抑制剂。此外,分子对接研究表明,化合物4u通过氢键,阳离子-π和疏水相互作用与微管蛋白的秋水仙碱结合位点具有很高的结合亲和力。
