To identify selective high-affinity inhibitors of the vesicular acetylcholine transporter (VAChT), we have interposed a carbonyl group between the phenyl and piperidyl groups of the prototypical VAChT ligand vesamicol and its more potent analogues benzovesamicol and 5-aminobenzovesamicol. Of 33 compounds synthesized and tested, 6 display very high affinity for VAChT (Ki, 0.25−0.66 nM) and greater than
为了鉴定水泡乙酰胆碱转运蛋白(VAChT)的选择性高亲和力抑制剂,我们在典型的VAChT配体维他命醇及其更有效的类似物苯并维他命和5-氨基苯并维他命的苯基和哌啶基之间插入了一个羰基基团。的合成和测试33个的化合物,6为显示中VAChT非常高的亲和力(ķ我,0.25-0.66 nM)的和大于在σ为500中VAChT倍的选择性1和σ 2个受体。十二种化合物具有很高的亲和力(K i,1.0-10 nM)和对VAChT的良好选择性。此外,还存在3种卤代化合物,即反式-3- [4-(4-氟苯甲酰基)哌啶基] -2-羟基-1,2,3,4-四氢萘(28b)(K i = 2.7 nM,VAChT / sigma选择性指数= 70),反式-3- [4-(5-碘噻吩基羰基)哌啶基] -2-羟基-1,2,3,4-四氢萘(28h)(K i = 0.66 nM,VAChT / sigma选择性指数= 294)和5-氨基-3-
