A series of N,N-(dialkylamino)alkylamides of several N-substituted α,β-dehydroamino acids and their quaternary ammonium salts were synthesized via the reaction of unsaturated 5(4H)-oxazolones with N,N-dialkyldiamines and characterized by physicochemical characteristics. Their reactions with human erythrocytic acetylcholinesterase (ACE) and plasmic butyrylcholinesterase (BuCE) were studied. The IC50 values [concentration at which the hydrolysis rate of cholinesterase was 50% inhibited by acetylthiocholine (0.1 mM)] of all synthesized compounds were determined. It was found that all synthesized compounds possessed anticholinesterase activity and were specific mainly for BuCE.
合成了一系列N,N-(二烷基氨基)烷基酰胺,涉及几种N取代的α,β-脱氢氨基酸及其季铵盐,反应通过不饱和5(4H)-氧唑烷与N,N-二烷基二胺进行,并通过物理化学特性进行了表征。研究了它们与人类红细胞乙酰胆碱酯酶(ACE)和血浆丁酰胆碱酯酶(BuCE)的反应。确定了所有合成化合物的IC50值(乙酰硫胆碱(0.1 mM)抑制胆碱酯酶水解速率50%的浓度)。结果发现,所有合成化合物均具有抗胆碱酯酶活性,并且主要特异性针对BuCE。
