inhibitors and evaluated for their antiproliferative activity in three human cancer cell lines. Most of the target compounds displayed moderate antiproliferative activity, and N-(2,4-dimethoxyphenyl)-4-(4-methoxyphenyl)-1,3-thiazol-2-amine (10s) was determined to be the most potent compound. Tubulin polymerization and immunostaining experiments revealed that 10s potently inhibited tubulin polymerization
设计并合成了一系列含有三个带有氨基接头的芳香环的N,4-二芳基-1,3-噻唑-2-胺,作为微管蛋白抑制剂,并评估了它们在三种人类癌细胞系中的抗增殖活性。大多数目标化合物均显示出适度的抗增殖活性,N-(2,4-二甲氧基苯基)-4-(4-甲氧基苯基)-1,3-噻唑-2-胺(10s)被确定为最有效的化合物。微管蛋白聚合和免疫染色实验表明,10s以类似于CA-4的方式有效抑制微管蛋白聚合并破坏微管蛋白微管动力学。此外,10s以浓度和时间依赖性方式有效地诱导了SGC-7901细胞周期阻滞在G2 / M期。分子对接结果表明10s可以结合微管蛋白的秋水仙碱结合位点。
