Galantamine (GAL) is a well-known acetylcholinesterase (AChE) inhibitor, and it is widely used for treatment of Alzheimer’s disease. GAL fits well in the catalytic site of AChE, but it is too short to block the peripheral anionic site (PAS) of the enzyme, where the amyloid beta (Aβ) peptide binds and initiates the Aβ aggregation. Here, we describe a docking-based technique for designing of GAL derivatives with dual-site binding fragments – one blocking the catalytic site and another blocking the PAS. The highly scored compounds are synthesized and tested. Protocols for docking, design, synthesis, and AChE inhibitory test are given.
加兰他敏 (GAL) 是一种众所周知的乙酰胆碱酯酶 (AChE) 抑制剂,广泛用于治疗阿尔茨海默病。GAL 在 AChE 的催化位点中契合良好,但它的长度不足以阻断酶的周边阴离子位点 (PAS),而该位点是淀粉样β (Aβ) 肽结合并启动 Aβ 聚集的地方。在这里,我们描述了一种基于对接的技术,用于设计具有双重位点结合片段的 GAL 衍生物——一个阻断催化位点,另一个阻断 PAS。我们合成并测试了评分高的化合物。本文提供了对接、设计、合成和 AChE 抑制测试的协议。
