The synthesis, biological evaluation and molecular modeling of a series of pyrrole compounds related to 3,5-dibromo-4-(3,4-dimethoxyphenyl)-1H-pyrrole-2-carboxylic acid that evaluates and optimizes C-4 substituents are reported. The key factor for microtubule depolymerization activity appears to be the presence of an appropriately positioned acceptor for Cys241β in the otherwise hydrophobic subpocket A.
报告了一系列与 3,5-二溴-4-(3,4-二甲氧基苯基)-1H-吡咯-2-羧酸有关的吡咯化合物的合成、生物学评价和分子建模,对 C-4 取代基进行了评估和优化。微管解聚活性的关键因素似乎是在原本疏水性的子口袋 A 中存在一个位置适当的 Cys241β 受体。
