To identify selective high-affinity ligands for the vesicular acetylcholine transporter (VAChT), we have incorporated a carbonyl group into the structures of trozamicol and prezamicol scaffolds, and also converted the secondary amines of the piperidines of trozamicols and prezamicols into amides. Of 18 new racemic compounds, 4 compounds displayed high affinity for VAChT (Ki = 10–20 nM) and greater
为了鉴定囊泡乙酰胆碱转运蛋白(VAChT)的选择性高亲和力配体,我们将羰基纳入特罗扎米考和普扎米考支架的结构中,并将特罗扎米考和普扎米考的哌啶的仲胺转化为酰胺。在 18 种新的外消旋化合物中,有 4 种化合物对 VAChT 显示出高亲和力 ( K i = 10–20 nM),并且对 VAChT 的选择性比σ 1和σ 2受体高出 300 倍以上,即 (4-(4-氟苯甲酰基)-4 '-羟基-[1,3'-联哌啶]-1'-基)(3-甲基噻吩-2-基)甲酮草酸酯 ( 9g ) ( K i-VAChT = 11.4 nM, VAChT/ σ 1 = 1063, VAChT/ σ 2 = 370), (1′-苯甲酰基-4′-羟基-[1,3′-联哌啶]-4-基)(4-甲氧基苯基)甲酮草酸酯 ( 10c ) ( K i-VAChT = 15.4 nM, VAChT / σ 1 = 374, VAChT/ σ
