A novel opioid ligand possessing a stable and cyclic imine 16 and its derivatives with an azabicyclo[2.2.2]octane skeleton were synthesized. The imine 16 showed higher affinity for the μ receptor than compound 21 with an oxabicyclo[2.2.2]octane skeleton. Azabicyclo[2.2.2]octane derivative 18d with a cyclopropylmethyl group on the 8-nitrogen showed the highest affinity for the μ receptor among the synthesized
合成了一种具有稳定的环状亚胺16的新型阿片样物质配体及其具有氮杂双环[2.2.2]辛烷骨架的衍生物。与具有氧杂双环[2.2.2]辛烷骨架的化合物21相比,亚胺16对μ受体的亲和力更高。在合成的衍生物中,在8-氮上带有环丙基甲基的氮杂双[2.2.2]辛烷衍生物18d对μ受体的亲和力最高。
