Molecules that target microtubules have an important role in the treatment of cancer. A new class of inhibitors of tubulin polymerization based on the 2-(3,4,5-trimethoxybenzoyl)-2-dimethylamino-benzo[b]furan molecular skeleton was synthesized and evaluated for antiproliferative activity, inhibition of tubulin polymerization, and cell cycle effects. The most promising compound in this series was 2-(3,4,5-trimethoxybenzoyl)-3-dimethylamino-6-methoxy-benzo[b]furan, which inhibits cancer cell growth at nanomolar concentrations and interacts strongly with tubulin by binding to the colchicine site.
靶向微管的分子在癌症治疗中具有重要作用。基于2-(3,4,5-三甲氧基苯甲酰基)-2-二甲基氨基苯并[b]呋喃分子骨架,合成了一类新型微管蛋白聚合抑制剂,并对其抗增殖活性、微管蛋白聚合抑制作用和细胞周期效应进行了评估。该系列中最有前景的化合物是2-(3,4,5-三甲氧基苯甲酰基)-3-二甲基氨基-6-甲氧基苯并[b]呋喃,它在纳摩尔浓度下就能抑制癌细胞生长,并通过与秋水仙碱结合位点结合而与微管蛋白强烈相互作用。
