The cytotoxicity of thirteen derivatives were investigated, as well as the effect of substituents in the phenyl ring on the activity of 1,2,3-triazoles. Limited activity was observed for some of these products. Most of the studied compounds were inactive in cancer cell lines and healthy fibroblasts. Triazole 46 exhibited cytotoxic activity against CEM and MCF-7 cancer cell lines, however, it was also
为了寻找基于羽扇豆支架的新细胞毒性衍生物,在 1,3-偶极环加成 (CuAAC) 条件下,s生态羽扇豆叠氮化物与许多炔烃偶联得到 1,2,3-三唑。在对位具有不同取代基的苯炔用作原料。类似地,将seco- lupane 硫氰酸盐与叠氮化钠偶联得到5-硫代四唑。研究了 13 种衍生物的细胞毒性,以及苯环中的取代基对 1,2,3-三唑活性的影响。观察到其中一些产品的活性有限。大多数研究的化合物在癌细胞系和健康的成纤维细胞中是无活性的。三唑46对 CEM 和 MCF-7 癌细胞系表现出细胞毒活性,然而,它对正常人 BJ 成纤维细胞也有毒性。其他两种衍生物——三唑45和四唑49——表现出低细胞毒性。与正常成纤维细胞相比,化合物49对肿瘤细胞系显示出良好的选择性。该化合物不影响正常人成纤维细胞的生长,因此具有广泛的治疗窗口。
