Inhibitors of acetylcholinesterase (AChE) have been designed based on a working hypothesis of the enzyme's active site. These compounds were tested for their inhibitory activities on AChE and ω-[N-ethyl-N-(phenylmethyl)amino]-1-phenyl-1-alkanones (3) were found to be potent inhibitors. Various analogues of 3 were prepared to study the effect on AChE inhibition of partial restriction of conformation. Compounds with potent AChE inhibition were further evaluated in terms of central selectivity : the ratio of central action (ameliorationg effect on scopolamine-induced memory impairment using a T-maze alternation task) to peripheral action.
乙酰胆碱酯酶(AChE)抑制剂的设计是基于酶的活性位点的工作假设。这些化合物被测试了其对AChE的抑制活性,ω-[N-乙基-N-(苯甲基)氨基]-1-苯基-1-烷酮(3)被发现是有效的抑制剂。为了研究构象部分限制对AChE抑制的影响,制备了3的各种类似物。具有强效AChE抑制的化合物进一步评估了其中心选择性:中心作用(在T型迷宫交替任务中改善斯科波拉明诱导的记忆损害的效果)与外周作用的比率。
