The synthesis, biological assessment, and molecular modelling of new tacrine analogues 11–22 is described. Compounds 11–22 have been obtained by Friedländer-type reaction of 2-aminopyridine-3-carbonitriles 1–10 with cyclohexanone or 1-benzyl-4-piperidone. The biological evaluation showed that some of these molecules were good AChE inhibitors, in the nanomolar range, and quite selective regarding the
的合成,生物评估,以及新的他克林类似物分子建模11 - 22进行说明。化合物11 - 22已经通过2-氨基吡啶-3-腈德兰德型反应得到的1 - 10与环己酮或1-苄基-4-哌啶酮。生物学评估表明,这些分子中的一些是良好的AChE抑制剂,在纳摩尔范围内,对BuChE的抑制作用具有选择性,最有效的是5-氨基-2-(二甲基氨基)-6,7,8,9-四氢苯并[1,8 - b ]-萘啶-3-腈(11)[IC 50(EeAChE:14 nM); IC 50(eqBuChE:5.2μM]。简便有效的有效胆碱甾族化合物5-氨基-2-(甲氧基)-6,7,8,9-四氢苯并[1,8 - b ]-萘啶-3-甲腈的动力学研究16)[IC 50(EeAChE:64 nM); IC 50(eqBuChE:9.6μM)表明该化合物是EeAChE的混合型抑制剂(K i = 69.2 nM)。对抑制剂16的分子模型证实了该化
