4‐dipyridine substituted 3,7‐diazabicyclo‐[ 3.3.1]nonanone diesters were found to have a high affinity and selectivity towards the κ‐opioid receptor. The purpose of this study was to check the influence of substituents at position N3 on the affinity to the μ‐, δ‐, and κ‐receptors. Whereas a phenylethyl group is able to create affinity to the μ‐receptor, small substituents such as a hydrogen or a methyl group
以前发现 2,4-二吡啶取代的 3,7-二氮杂双环-[3.3.1]壬酮二酯对 κ-阿片受体具有高亲和力和选择性。本研究的目的是检查 N3 位取代基对 μ-、δ-和 κ-受体亲和力的影响。苯乙基能够对 μ 受体产生亲和力,而小取代基如氢或甲基则对 κ 受体具有高亲和力。此外,发现二聚体化合物对 κ 受体具有亲和力。尽管所有化合物在生理条件下都至少带有一个正电荷,但它们显示出相当大的亲脂性,表明有可能通过血脑屏障。
