A novel series of tacrine-lophine hybrids was synthesized and tested for their ability to inhibit acetylcholinesterase (AChE) and butyrylcholinesterase (BuChE) with IC50 in the nanomolar concentration scale. The key step is the one-pot four component condensation reaction of 9-aminoalkylamino-1,2,3,4-tetrahydroacridines, benzil, different substituted aromatic aldehydes and NH4OAc, using InCl3 as the
合成了一系列新的他克林-丝氨酸杂种,并测试了它们在纳摩尔浓度范围内以IC 50抑制乙酰胆碱酯酶(AChE)和丁酰胆碱酯酶(BuChE)的能力。关键步骤是使用InCl 3作为最佳催化剂,使9-氨基烷基氨基-1,2,3,4-四氢ac啶,苄基,不同取代的芳族醛与NH 4 OAc进行一锅四组分缩合反应。发现他克林-丝氨酸杂种是胆碱酯酶的有效和选择性抑制剂。作为四组分方法向四取代咪唑的扩展,针对AChE和BuChE测试了一系列新的双-(2,4,5-三苯基-1 H-咪唑)或双(n)-卵磷脂。
