1-[6-(Acridine-9-carbonyloxy)hexyl]pyridinium chloride (1) was synthesized and studied as a potential inhibitor of acetylcholinesterase (AChE), which is frequently involved in Alzheimer's disease. UV spectrophotometry showed that 1 is a reversible and competitive inhibitor of AChE (Ki ≈ 2 × 10−7 M). NMR (TrNOESY) showed that 1, bonded to AChE, maintains an extended form that allows hydrophobic interactions
合成了1- [6-(A啶-9-羰氧基)己基]吡啶鎓氯化物(1),并研究了其为乙酰胆碱酯酶(AChE)的潜在抑制剂,该酶经常参与阿尔茨海默氏病。紫外分光光度法表明,1是乙酰胆碱酯酶(的可逆和竞争性抑制剂ķ我 ≈2×10 -7 中号)。NMR(TrNOESY)显示1与AChE结合的分子,保持扩展的形式,允许脂族链与AchE的深而窄的峡谷之间发生疏水相互作用,并促进the啶基与位于峡谷底部的催化和阴离子亚位之间的相互作用,并且在吡啶环和外围位点之间。通过将NMR结构数据和分子建模(对接,动力学模拟和能量计算)相结合,可以获得复合物结构的更详细的图片。版权所有©2006 John Wiley&Sons,Ltd.
