(3R)-7-Hydroxy-N-((1S)-1-[[(3R,4R)-4-(3-hydroxyphenyl)-3,4-dimethyl-1-piperidinyl ]methyl]-2-methylpropyl)-1,2,3,4-tetrahydro-3-isoquinolinecarboxamide (JDTic) was identified as a potent and selective kappa opioid receptor antagonist. Structure-activity relationship (SAR) studies on JDTic analogues revealed that the 3R,4R stereochemistry of the 3,4-dimethyl-4-(3-hydroxyphenyl)piperidine core structure
(3R)-7-羟基-N-((1S)-1-[[((3R,4R)-4-(3-羟苯基)-3,4-二甲基-1-哌啶基]甲基] -2-甲基丙基) -1,2,3,4-四氢-3-异喹啉羧酰胺(JDTic)被确定为有效的选择性κ阿片受体拮抗剂。对JDTic类似物的结构活性关系(SAR)研究表明,3,4-二甲基-4-(3-羟基苯基)哌啶核心结构的3R,4R立体化学,7-羟基-1,2的3R附着, 3,4-四氢异喹啉基团和2-甲基丙基(异丙基)基团的1S构型均对其Kappa效能和选择性很重要。结果表明,与其他kappa阿片类拮抗剂(例如nor-BNI和GNTI)一样,JDTic在[(35)S] GTPgammaS功能测定中需要第二个碱性氨基来表达有效和选择性的kappa拮抗剂活性。然而,与先前报道的Kappa拮抗剂不同,JDTic还需要第二酚基团,该第二酚基团必须紧靠该第二碱性氨基。可以使用“消息地址”概念合理
