5-dicarbonitrile (2) is described. The biological evaluation showed that some of these molecules were modest inhibitors of acetylcholinesterase (AChE) and butyrylcholinesterase (BuChE), in the micromolar range. The 2-amino (3, 4), and 2-chloro derivatives 21–23, 25, 26 were AChE selective inhibitors, whereas 2-amino derivatives 5, 14 proved to be selective for BuChE. Only inhibitor 24 was equipotent
合成,分子建模和药理学分析的新的多能简单易用的2-氨基吡啶-3,5-二碳腈(3 – 20)和2-氯吡啶-3,5-二碳腈(21 – 28),其制备方法如下:描述了2-氨基-6-氯吡啶-3,5-二甲腈(1)和2-氨基-6-氯-4-苯基吡啶-3,5-二甲腈(2)。生物学评估表明,其中一些分子在微摩尔范围内是适度的乙酰胆碱酯酶(AChE)和丁酰胆碱酯酶(BuChE)抑制剂。2-氨基(3,4),和2-氯衍生物21 - 23,25,26是乙酰胆碱酯酶选择性抑制剂,而2-氨基衍生物5,14证明为BuChE的是选择性的。对于两种胆碱酯酶,仅抑制剂24是等价的。对化合物23的动力学研究表明,该化合物是AChE的混合型抑制剂,K i为6.33μM。从这些数据无法获得清晰的SAR,但显然,不管吡啶环中是否存在2-氨基或6-氯取代基,带有N,N'-二甲基氨基或吡咯烷基等小基团的化合物,优先抑制AChE。上抑制剂分
