of (−)-phenserine (12), (−)-tolserine (14), (−)-cymserine (16) and (−)-phenethylcymserine (18) were synthesized to produce long-acting peripheral inhibitors of acetylcholinesterase or butyrylcholinesterase. Evaluation of their cholinesterase inhibition against human enzyme ex vivo demonstrated that, whereas compounds 5–8 possessed only marginal activity, 12, 14, 16 and 18 proved to be potent anticholinesterases
硫酸新斯的明 ( 6 ) 和溴化吡啶斯的明 ( 8 )的N-单苯基氨基甲酸酯类似物及其前体 ( 5 )、( 7 ) 和(-)-苯丝氨酸的N (1)-甲基铵类似物 ( 12 )、( -)-托丝氨酸 ( 14 )、(-)-cymserine ( 16 ) 和(-)-phenethylcymserine ( 18 ) 被合成以产生乙酰胆碱酯酶或丁酰胆碱酯酶的长效外周抑制剂。它们对人酶的离体胆碱酯酶抑制的评价,结果证实,而化合物5 - 8只拥有边际活性,12,14,16和18被证明是有效的抗胆碱酯酶。在啮齿动物中确定了延长的胆碱酯酶抑制持续时间,使它们作为重症肌无力的长效药物具有潜在的兴趣。
