interact with both μ- and δ-opioid receptors. A C4a-phenethyl derivative 2a, was found to have modest receptor affinity both at μ- (Ki = 60 nM) and δ-opioid receptors (Ki = 64 nM). The N-methyl substituent of 2a and that of other ligands in the series was then modified to obtain compounds with different N-substituents that might provide higher affinity at both receptors. A number of compounds differently
已经制备了一系列N-甲基外消旋-顺式-4a-芳烷基-和烷基-取代的-1,2,3,4,4a,9a-六氢苯并呋喃[2,3 - c ]吡啶-6-醇(2a - l ) 使用先前设计的简单合成路线,以找到可与 μ- 和 δ-阿片受体相互作用的配体。发现C4a-苯乙基衍生物2a对 μ- ( K i = 60 nM) 和 δ-阿片受体 ( K i = 64 nM)都具有适度的受体亲和力。2a的N-甲基取代基然后修改该系列中其他配体的配体以获得具有不同 N 取代基的化合物,这些 N 取代基可能对两种受体提供更高的亲和力。合成并评估了许多在 C4a 和 N 处不同取代的化合物。结合研究和功能测定揭示了中等选择性 δ-拮抗剂 ( 2l )、选择性 μ-δ 拮抗剂 ( 3d、3g ) 和 μ-κ 拮抗剂 ( 3f )。
