Inspired by the crucial roles of (hetero)aryl rings in cholinesterase inhibitors and the pyrrole ring in new drug discovery, we synthesized 19 pyrrole derivatives and investigated their cholinesterase inhibitory activity. As a result, compounds 3o, 3p, and 3s with a 1,3-diaryl-pyrrole skeleton showed high selectivity toward BChE over AChE with a best IC50 value of 1.71 ± 0.087 µM, which were comparable
受(杂)芳基环在胆碱酯酶抑制剂中的关键作用和吡咯环在新药发现中的启发,我们合成了 19 种吡咯衍生物并研究了它们的胆碱酯酶抑制活性。因此,具有 1,3-二芳基吡咯骨架的化合物 3o、3p 和 3s 对 BChE 的选择性高于 AChE,具有最佳 IC50值为 1.71 ± 0.087 µM,与多奈哌齐相当。进一步预测了这些结构的药物潜力,并证明化合物3o和3p很好地满足Lipinsky的五个规则。结合抑制动力学研究和分子对接结果,我们得出结论,化合物 3p 以混合竞争模式抑制 BChE。该研究证明了1,3-二芳基吡咯骨架作为一种选择性BChE抑制剂的潜力。
