The synthesis, biological evaluation and molecular modeling of new multipotent inhibitors of type I and type II, able to simultaneously inhibit monoamine oxidases (MAO) as well as acetylcholinesterase (AChE) and butyrylcholinesterase (BuChE), is described. Compounds of type I were prepared by sequential reaction of 2,6-dichloro-4-phenylpyridine-3,5-dicarbonitrile (14) [or 2,6-dichloropyridine-3,5-dicarbonitrile
描述了能够同时抑制单胺氧化酶(MAO)以及乙酰胆碱酯酶(AChE)和丁酰胆碱酯酶(BuChE)的新型I型和II型多功能抑制剂的合成,生物学评估和分子模型。通过使2,6-二氯-4-苯基吡啶-3,5-二甲腈(14)[或2,6-二氯吡啶-3,5-二甲腈(15)]与prop-2-依次反应来制备I型化合物炔-1-胺(或N-甲基丙-2-炔-1-胺)和2-(1-苄基哌啶-4-基)烷基胺22–25。II型化合物通过6-氨基-5-甲酰基-2-(甲基(丙-2-炔-1-基)氨基)烟腈32和33与4-(1-苄基哌啶-4-基)丁烷-的弗里德兰德型反应制备。2一(31)。分子1–11的生物学评估表明,这些化合物大多数在纳摩尔范围内都很有效,并具有选择性的AChEI,对MAO-A和MAO-B的抑制作用具有中等和均等的选择性。化合物8的动力学研究证明,它是Ee AChE混合型抑制剂(IC 50 = 16±2; Ki =
