Based on our previous work, a series of novel triazolylthioacetones incorporating pyridine, pyrazine, and 3,4,5-trimethoxybenzyl fragment were synthesized, and evaluated for antiproliferative activities and interactions with tubulin. Some analogues exhibited moderate to excellent potency, with the most promising compound IIc possessing IC50 values of 0.62, 1.46, and 3.65 μM against HT-29, HCT116, and
基于我们之前的工作,合成了一系列包含吡啶、吡嗪和 3,4,5-三甲氧基苄基片段的新型三唑基硫代丙酮,并评估了其抗增殖活性和与微管蛋白的相互作用。一些类似物表现出中等至极好的效力,最有希望的化合物IIc对 HT-29、HCT116 和 HepG2 肿瘤细胞的IC 50值分别为 0.62、1.46 和 3.65 μM,与阳性对照 CA-4 相当. 机制研究表明,IIc浓度依赖性地导致 HCT116 肿瘤细胞 G 2 /M 期的细胞周期停滞,并显示显着抑制微管蛋白聚合的 IC 50值为 12.7 μM。此外,分子对接分析表明,IIc 可以以与典型的微管蛋白聚合 抑制剂类似的方式占据秋水仙碱结合位点。这些结果突出了 4-氨基-三唑基硫代丙酮支架作为开发高效抗癌剂的潜在微管蛋白聚合抑制剂。
