[2+3]-cyclocondensation reaction of 1,2,4-triazole-3(5)-thiol with N-arylmaleimides or with monochloroacetic acid and oxocompounds, N-(R-phenyl)-(6-oxo-5,6-dihydro[1,3]thiazol[3,2-b][1,2,4]triazol-5-yl)acetamides (1-5) and 5-ylidene-[1,3]thiazolo[3,2-b][1,2,4]triazol-6-ones (6-11) were synthesized as possible anticancer agents. Anticancer activity evaluation on the full panel of nearly 60 human cancer cell lines
1,2,4-三唑-3(5)-硫醇与N-芳基马来酰亚胺或一氯乙酸和氧代化合物的[2 + 3]-环缩合反应后,N-(R-苯基)-(6-氧代-5) 6-二氢[1,3]噻唑[3,2-b] [1,2,4]三唑-5-基)乙酰胺(1-5)和5-亚甲基-[1,3]噻唑[3,2]合成了-b] [1,2,4]三唑-6-酮(6-11)作为可能的抗癌药。在将近60种人类癌细胞系中进行了全面的抗癌活性评估,结果表明合成的化合物对肾癌,白血病,结肠癌,乳腺癌和黑色素瘤细胞系表现出这种活性。结果表明5-亚丙基-[1,3]噻唑并[3,2-b] [1,2,4]三唑-6-酮比各自的酰胺具有更强的抗癌活性。化合物的结构通过(1)H NMR,(13)C NMR和X射线分析确定。
