1,5-disubstituted 1,2,3-triazole analogues of combretastatin A-4 (1) have been prepared. The triazole 12f, 2-methoxy-5-(1-(3,4,5-trimethoxyphenyl)-1H-1,2,3-triazol-5-yl)aniline, displayed potent cytotoxic activity against several cancer cell lines with IC(50) values in the nanomolar range. The ability of triazoles to inhibit tubulin polymerization has been evaluated, and 12f inhibited tubulin polymerization
制备了康布雷他汀A-4(1)的一系列顺式限制1,5-二取代1,2,3-三唑类似物。三唑12f,2-甲氧基-5-(1-(3,4,5-三甲氧基苯基)-1H-1,2,3-三唑-5-基)苯胺对IC的几种癌细胞系表现出有效的细胞毒活性(50)值在纳摩尔范围内。已经评估了三唑抑制微管蛋白聚合的能力,并且12f以IC(50)= 4.8microM抑制微管蛋白聚合。涉及12f和秋水仙碱的α,β-微管蛋白结合位点的分子模型实验表明,三唑部分通过与几个氨基酸的氢键与β-微管蛋白相互作用。
