literature, confirmed that alkyl substitution on aroyl moiety of molecules is requisite for inhibition activity. The presence of hydrophobic moiety at close distance from hydrogen bond acceptor has favorable influence on inhibition potency. Docking studies show that compounds probably bind in the middle of the AChE active site gorge, but are buried deeper inside BChE active site gorge, as a consequence
4-芳基-4-氧代-N的合成及抗胆碱酯酶活性据报道,新型的可逆的,中等效力的胆碱酯酶抑制剂-苯基-2-氨基丁基丁酰胺。芳酰基部分上的简单取代基变化将抗AChE活性改变了两个数量级。丁酸部分2位的杂(ali)环的取代和类型也决定了AChE / BChE的选择性。最有效的化合物表现出混合型抑制作用,表明它们与游离酶和酶-底物复合物结合。对报道的化合物以及具有从文献中获得的具有类似效力的化合物的与排列无关的3D QSAR研究证实,分子的芳酰基部分上的烷基取代是抑制活性所必需的。距离氢键受体很近的疏水部分的存在对抑制效能具有有利的影响。
