agents, giving access to a wide range of substitution patterns at the 2-position of the 6-methoxybenzo[b]thiophene common intermediate. In the present study, all the synthesized compounds retained the 3-(3,4,5-trimethoxyanilino)-6-methoxybenzo[b]thiophene moiety, and the structure–activity relationship was examined by modification of the aryl group at its 2-position with electron-withdrawing (F) or electron-releasing
许多临床上在癌症化疗中使用的活性剂通过靶向微管、改变蛋白质功能或抑制 DNA 合成诱导细胞死亡(细胞凋亡)发挥其活性。苯并[ b ] 噻吩支架作为抗癌药物开发的药效基团具有举足轻重的地位,此外,该支架还具有许多药理活性。我们开发了一种灵活的方法来构建新系列的 2-芳基-3-(3,4,5-三甲氧基苯胺基)-6-甲氧基苯并[ b ]噻吩作为有效的抗增殖剂,从而获得广泛的取代6-甲氧基苯并[ b] 2-位的模式]噻吩常用中间体。在本研究中,所有合成的化合物都保留了 3-(3,4,5-三甲氧基苯胺基)-6-甲氧基苯并[ b ]噻吩部分,并通过修饰芳基在其 2-位置与吸电子 (F) 或电子释放 (烷基和烷氧基) 基团。我们发现小的取代基,例如氟或甲基,可以放置在2-苯基环的对位,并且这些修饰相对于未取代的 2-苯基类似物仅略微降低抗增殖活性。化合物3a和3b,在6-甲氧基苯并[ b]的2-位带有苯基
