In an attempt to mimic the 3,4,5-trimethoxyphenyl-Z-stilbene moiety of combretastatin A-4, a series of N-aryl-5,6,7-trimethoxyindoles were synthesized via copper-catalyzed Ullmann-type N-arylation through the corresponding 5,6,7-trimethoxyindole and aryl halides. These synthesized compounds demonstrated potent antiproliferative activity providing a novel skeleton for potent tubulin polymerization inhibitors.
为了模拟 combretastatin A-4 中的 3,4,5-三甲氧基苯基-Z-苯乙烯结构,合成了一系列 N-芳基-5,6,7-三甲氧基吲哚化合物,采用通过相应的 5,6,7-三甲氧基吲哚和芳基卤化物进行的铜催化 Ullmann 型 N-芳基化反应。这些合成的化合物显示出强大的抗增殖活性,为有效的微管聚合抑制剂提供了新的骨架。
