Thirty-two novel 3-alkylsulfanyl-1,2,4-triazole derivatives, designed as cis-restricted combretastatin A-4 analogues, were synthesized and evaluated for their antiproliferative activities. The results indicated that analogue 20 showed more potent antiproliferative activities against PC-3 cell lines than positive control CA-4. Particularly, the most promising compound 25 displayed 5-fold improvement
合成了32种新颖的3-烷基硫烷基-1,2,4-三唑衍生物,设计为顺式限制的康他汀A-4类似物,并评估了它们的抗增殖活性。结果表明,与阳性对照CA-4相比,类似物20对PC-3细胞系显示出更强的抗增殖活性。特别是,最有前途的化合物25在抑制HCT116细胞增殖方面的作用与CA-4相比提高了5倍,IC 50值为1.15μM。进一步的流激活细胞分选分析表明,化合物20在PC-3细胞中对G 2 / M细胞周期停滞具有显着的剂量依赖性。根据这项研究,类似物20和25是该结构类别中最有效的抗癌药,被认为是作为抗癌药有待进一步开发的先导化合物。
