synthesized as acetylcholinesterase (AChE) and/or butyrylcholinesterase (BuChE) inhibitors. The AChE inhibition potency of synthetic oxoaporphine derivatives was decreased about 2–3 orders of magnitude as compared with that of oxoisoaporphine derivatives. Non-competitive binding mode was found for both kinds of derivatives. Molecular docking simulations on the oxoisoaporphine derivatives 7 series and
从中草药中分离出的Aporphine生物碱是重要的天然产物。我们最近报道说,氧代异aphophine生物碱的合成衍生物比BuChE表现出较高的乙酰胆碱酯酶抑制活性和对AChE的高选择性(Bioorg。Med。Chem。Lett。2007,17,3765-3768)。本文提出了进一步的研究结果。一系列新的氧杂卟啉生物碱衍生物(5a - j,4-羧酸酰胺-7-氧代-7 H-二苯并[ de,g ]喹啉,Ar-CONH(CH 2)n NR)及其季me盐(6a – h,Ar-CONH(CH 2)n N+(CH 3)RI -设计和为乙酰胆碱酯酶和/或丁酰胆碱酯酶(BuChE的)抑制剂合成)。合成的氧磷卟啉衍生物的AChE抑制能力与氧代异吗啡衍生物相比降低了约2-3个数量级。两种衍生物都发现了非竞争性结合模式。氧代异aporphine衍生物7系列和oxoaporphine衍生物6系列与来自加州鱼雷的AC
