This study describes the synthesis of a series of novel substituted 1-(aminomethyl)-2-(arylacetyl)-1,2,3,4-tetrahydroisoquinolines, and discusses their structure-activity relationships (SARs) using binding affinity for opioid receptors and antinociceptive potency as the indices of biological activity. The introduction of a hydroxy substituent in position 5 of the isoquinoline nucleus generated a compound
这项研究描述了一系列新型取代的1-(氨基甲基)-2-(芳基乙酰基)-1,2,3,4-四氢异喹啉的合成,并讨论了它们对阿片受体的结合亲和力与它们的结构活性关系(SAR)。抗伤害感受力作为生物活性的指标。在异喹啉核的5位上引入羟基取代基产生了一种化合物40,其效力比抗伤害感受的小鼠模型中先前公开的未取代类似物39强2倍。对5-取代基的QSAR分析清楚地表明,抗伤害感受活性与取代基的亲脂性成反比。与未取代的异喹啉39相比,本文所述的取代化合物对κ阿片受体的选择性较低。5-羟基取代的化合物59对kappa阿片受体具有很高的亲和力(Ki kappa = 0.09 nM),Ki mu / Ki kappa之比仅为5。但是,多元线性回归分析表明,抗伤害性与对μ阿片样物质受体的亲和力。另一方面,对κ阿片受体的结合亲和力与抗伤害感受活性之间的相关性具有统计学意义。
