benzene portion of the 3-(3′,4′,5′-trimethoxyanilino)benzo[b]furan skeleton, were evaluated for antiproliferative activity against cancer cells in culture and, for selected, highly active compounds, inhibition of tubulin polymerization, cell cycle effects, and in vivo potency. The greatest antiproliferative activity occurred with a methoxy group introduced at the C-6 position, the least with this substituent
一系列新的化合物,其特征在于在3-(3',4',5的苯部分的四个可能位置中的每个位置上都没有取代基或甲氧基的情况下,存在2-甲氧基/乙氧基羰基的组合评价了'-三甲氧基苯胺基)苯并[ b ]呋喃骨架对培养中癌细胞的抗增殖活性,并针对选定的高活性化合物,抑制了微管蛋白的聚合反应,细胞周期效应和体内效力。最大的抗增殖活性是在C-6位置引入甲氧基,而在C-4位置具有最小取代基。到目前为止,该系列中最有希望的化合物是2-甲氧基羰基-3-(3',4',5'-三甲氧基苯胺基)-6-甲氧基苯并[ b ]呋喃(3g)以纳摩尔浓度(IC 50值为0.3–27 nM)抑制癌细胞的生长,并与微管蛋白的秋水仙碱位点结合,诱导细胞凋亡,并在体外和体内均显示出源自这种作用的有效血管破坏特性该化合物对血管内皮细胞的作用。化合物3g在鼠模型中具有体内抗肿瘤活性,与用康普他汀A-4磷酸酯获得的活性相当。
