synthesized a series of new graveoline analogs on the basis of the structural characteristics of acetylcholinesterase (AChE) dual-site inhibitors. The activity of these analogs was also evaluated. Results showed that the synthesized graveoline analogs displayed stronger inhibitory activity against AChE and higher selectivity than butyrylcholine esterase (BuChE) (Selectivity Index from 45 to 486).

本研究根据乙酰胆碱酯酶(AChE)双位点抑制剂的结构特点,设计并合成了一系列新的草甘膦类似物。还评估了这些类似物的活性。结果表明,合成的石蜡碱类似物对 AChE 显示出更强的抑制活性和比丁酰胆碱酯酶 (BuChE) 更高的选择性(选择性指数从 45 到 486)。当取代苯基和氨基末端的graveoline母环中的两个位点具有六个化学键(n = 3)且末端氨基为哌啶时,化合物5c显示出最佳活性。此外,通过酶动力学模拟、分子对接和基于硫黄素 T 的荧光测定法探索了作用机制和结合模式。
