  基于苯并恶嗪核心的潜在乙酰胆碱酯酶抑制剂的合成和生物学评价

  摘要：

  为了扩大可用作治疗阿尔茨海默病的药理学工具的化合物的结构多样性，我们合成并评估了一系列用于潜在人类乙酰胆碱酯酶的新型吲哚-苯并恶嗪酮（家族 I）和苯并恶嗪-芳基哌嗪衍生物（家族 II） (hAChE) 抑制特性。最活跃的化合物 7a 和 7d 显示出有效的抑制特性，Ki 值分别为 20.3 ± 0.9 μM 和 20.2 ± 0.9 μM。动力学抑制试验显示受试化合物对 AChE 具有非竞争性抑制作用。根据我们的对接研究，两个系列（家族 I 和 II）中最活跃的化合物显示出与多奈哌齐相似的结合模式，并与相同的残基相互作用。
