Diaryldimethylpiperazine ligands with μ- and δ-opioid receptor affinity: Synthesis of (+)-4-[(αR)-α-(4-allyl-(2S,5S)-dimethylpiperazin-1-yl)-(3-hydroxyphenyl)methyl]-N-ethyl-N-phenylbenzamide and (−)-4-[(αR)-α-(2S,5S)-dimethylpiperazin-1-yl)-(3-hydroxyphenyl)methyl]-N-ethyl-N-phenylbenzamide

explored the synthesis of compounds that have good affinity for both mu- and delta-opioid receptors from the (alphaR,2S,5S) class of diaryldimethylpiperazines. These non-selective compounds were related to opioids that have been found to interact selectively with mu- or delta-opioid receptors as agonists or antagonists. In our initial survey, we found two compounds, (+)-4-[(alphaR)-alpha-(4-allyl-(2S,5S)
我们已经从二芳基二甲基哌嗪的(alphaR,2S,5S)类中探索了对mu和delta类阿片受体均具有良好亲和力的化合物的合成。这些非选择性化合物与阿片类物质有关,已发现它们与作为激动剂或拮抗剂的mu-或δ阿片类受体选择性相互作用。在我们的初步调查中,我们发现了两种化合物,(+)-4-[(alphaR)-α-(4-烯丙基-(2S,5S)-二甲基哌嗪-1-基)-(3-羟基苯基)甲基] -N -乙基-N-苯基苯甲酰胺(14)及其NH相对的(-)-4-[(alphaR)-alpha-(2S,5S)-二甲基哌嗪-1-基)-(3-羟基苯基)甲基] -N-乙基-N-苯基苯甲酰胺(15),它与δ受体具有良好的亲和力,并且,正如我们希望的那样,对mu受体的亲和力比SNC80高得多。(+)-4-[(alphaR)-alpha-(4-allyl-(2S,通过X射线晶体学分析未解决的孪晶,确定5S)-二甲基-1-
