base with trimethoxy group on benzothiazole moiety, 4y was the best. This was followed by the synthesis of a series of the designed molecules by a convenient synthetic route and evaluation of their anticancer potential. Most of the compounds have shown significant growth inhibition against the tested cell lines and the compound 4y exhibited good antiproliferative activity with a GI50 value of 3.8µM specifically
根据我们以前的结果和文献的先验,通过对一些选定的分子进行分子建模实验,合理设计了一系列2-苯胺基吡啶基-苯并噻唑席夫碱。对接分子的结合能优于E7010,苯并噻唑部分带有三甲氧基的席夫碱为4y最佳。然后通过便利的合成途径合成一系列设计的分子,并评估其抗癌潜力。大多数化合物对受试细胞系均显示出显着的生长抑制作用,并且化合物4y表现出良好的抗增殖活性,尤其是针对DU145细胞系的GI50值为3.8µM。与对接结果一致,4y通过有效结合到秋水仙碱域中来抑制微管蛋白聚合,从而破坏微管动力学,从而产生了细胞毒性,与E7010相当。通过分子对接研究了4y与微管蛋白秋水仙碱结合位点的详细结合方式。此外,正如线粒体膜电位,caspase-3和膜联蛋白V-FITC分析等生物学研究所证明的,4y诱导了细胞凋亡。
