Abstract

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.

摘要

报道了一系列与3,5-二溴-4-(3,4-二甲氧基苯基)-1H-吡咯-2-羧酸相关的吡咯化合物的合成、生物学评价及分子模拟,该研究对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的亚口袋A中存在一个位置合适的Cys241β受体。
