the B-ring, 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-(4′-ethoxyphenyl)-benzo[b]thiophene (4e), which significantly inhibited cancer cell growth at submicromolar concentrations, especially against HeLa and Jurkat cells, and interacted with tubulin
微管在有丝分裂和间期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 ]噻吩等小分子作为微管蛋白聚合的抑制剂很有吸引力。因此,一类新的化合物结合了 2-(3',4',5'-三甲氧基苯甲酰基)-3-芳基/芳氨基苯并[ b ]噻吩分子骨架的结构基序,具有给电子(Me, OMe 、SMe 或 OEt) 或 B 环上的吸电子(F 和 Cl)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。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-(4'-乙氧基苯基)-苯并[ b ]噻吩(4e ),在亚微摩尔浓度下显着抑制癌细胞生长,尤其是对 HeLa 和 Jurkat 细胞的抑制,并与微管蛋白相互作用。通过流式细胞术分析确定,4e以时间和浓度依赖性方式引起 G2/M 期阻滞和细胞凋亡。G2/M 的阻断与细胞周期蛋白 B1 的表达增加和 cdc25c 的磷酸化相关。此外,4e扰乱线粒体膜电位并引起
