anticancer agents. Small molecules such as benzo[b]furans are attractive as inhibitors of tubulin polymerization. Thus, a new class of inhibitors of tubulin polymerization based on the 2-(3′,4′,5′-trimethoxybenzoyl)-benzo[b]furan molecular skeleton, with electron-donating (Me, OMe or OH) or electron-withdrawing (F, Cl and Br) substituents on the benzene ring, was synthesized and evaluated for antiproliferative
微管在有丝分裂和细胞分裂中的生物学重要性使它们成为开发抗癌剂的有趣目标。苯并[ b ]呋喃等小分子作为微管蛋白聚合的抑制剂很有吸引力。因此,一类新的微管蛋白聚合抑制剂基于 2-(3',4',5'-三甲氧基苯甲酰基)-苯并[ b ]呋喃分子骨架,具有供电子(Me、OMe 或 OH)或电子-去除苯环上的(F、Cl 和 Br)取代基,合成并评估其抗增殖活性、抑制微管蛋白聚合和细胞周期效应。在 C-3 位置添加甲基导致活性增加。该系列中最有前途的化合物是2-(3',4',5'-三甲氧基苯甲酰基)-3-甲基-6-乙氧基-苯并[b ]呋喃,其在纳摩尔浓度下抑制癌细胞生长,并通过与秋水仙碱位点结合而与微管蛋白强烈相互作用。
