5-trimethoxyphenyl moiety were synthesized, and evaluated for antiproliferative activities. Among them, compounds IIa, IIIh, and IIIm demonstrated significant antiproliferative activities against a panel of tumor cell lines, and the promising compound IIIm dose-dependently caused G2/M phase arrest in HeLa cells. Furthermore, analogue IIa exhibited the most potent tubulin polymerization inhibitory activity with an IC50
基于我们之前的研究,合成了 30 种新的具有 3,4,5-三甲氧基苯基部分的 5-氨基-1H-1,2,4-三唑,并评估了抗增殖活性。其中,化合物IIa、IIIh和IIIm对一组肿瘤细胞系显示出显着的抗增殖活性,并且有希望的化合物IIIm剂量依赖性地导致 HeLa 细胞的 G2/M 期停滞。此外,类似物IIa表现出最有效的微管蛋白 聚合抑制活性,IC 50值为 9.4 μM,分子建模研究表明IIa 在微管蛋白的秋水仙碱结合位点形成稳定的相互作用,表明 5-amino-1H-1,2,4-三唑支架具有进一步研究开发具有抗癌活性的新型微管蛋白聚合抑制剂的潜力。
