first potent and selective kappa opioid receptor antagonist from the 5-(3-hydroxyphenyl)morphan class of opioids. In this study we report an improved synthesis of this class of compounds. The new synthetic method was used to prepare analogues 5b-r where the morphan N-substituent and 7alpha-amido group were varied. Most of the analogues showed sub-nanomolar potency for the kappa opioid receptor and were
在先前的研究中,我们确定了(-)-N-[(1R,4S,5S,7R)-5-(3-羟苯基)-4-甲基-2-(3-苯丙基)-2-氮杂双环[3.3。 1] non-7-基] -3-(1-哌啶基)丙酰胺(5a,KAA-1)是来自5-(3-羟苯基)吗啡类阿片类药物的第一种有效的选择性kappa阿片受体拮抗剂。在这项研究中,我们报告了这类化合物的改进合成。该新的合成方法用于制备类似物5b-r,其中吗啡N-取代基和7α-酰胺基是不同的。大多数类似物对κ阿片受体表现出亚纳摩尔效价,并且相对于μ和δ阿片受体具有高度选择性。(-)-3-(3,4-二氢异喹啉-2(1H)-基)-N-((1R,4S,5S,7R)-5-(3-羟苯基)-4-meth-2-[[ 2-(2-甲基苯基)乙基] -2-氮杂双环[3.3.1]非-7-基}丙酰胺(5n,
