selective mu–kappa agonist, N-naphthoyl-β-naltrexamine 1, as the prototype ligand, a series of closely relatednaphthalene analogues were synthesized to study the chemical space around the naphthalene moiety in an effort to evaluate how receptor selectivity is affected by chemical modification. Nine analogues (2–10) of compound 1 were synthesized and tested on HEK-293 cells expressing homomeric and heteromeric

Opioid receptor selectiveantagonists are important pharmacological probes in opioid receptor structural characterization and opioid agonist functional study. Thus far, a nonpeptidyl, highly selective and reversible μ opioid receptor (MOR) antagonist is unavailable. On the basis of our modeling studies, a series of novel naltrexamine derivatives have been designed and synthesized. Among them, two compounds
阿片受体选择性拮抗剂是阿片受体结构表征和阿片激动剂功能研究中重要的药理学探针。迄今为止,还没有一种非肽基、高选择性和可逆的μ阿片受体(MOR)拮抗剂。在我们的建模研究的基础上,设计并合成了一系列新型纳曲胺衍生物。根据体外和体内测定的结果,其中有两种化合物被鉴定为先导化合物。它们都对 MOR 表现出高结合亲和力( K = 0.37 和 0.55 nM)。化合物6 (NAP) 对 MOR 的选择性比 δ 受体 (DOR) 高出 700 倍以上,对 κ 受体 (KOR) 的选择性高出 150 倍以上。化合物9 (NAQ) 对 MOR 的选择性比 DOR 高 200 倍以上,对 KOR 的选择性高约 50 倍。因此,这两种新型配体将作为进一步开发更有效和选择性的 MOR 拮抗剂的先导。
