pharmacological profile of the delta (δ) selective opioid agonist compound SNC-80, conformationally constrained analogs containing two diazatricyclodecane ring systems in place of dimethylpiperazine core motif were synthesized. The compounds showed subnanomolar or low nanomolar δ opioid receptor binding affinity. Depending upon the substituents on the diazatricyclodecane ring, these compounds displayed varying selectivity
考虑到δ(δ)选择性阿片样物质激动剂化合物SNC-80的有趣的药理学特征,合成了包含两个二氮杂三环癸烷环系统代替二甲基哌嗪核心基序的受构象约束的类似物。 这些化合物表现出亚纳摩尔或低纳摩尔δ阿片受体结合亲和力。取决于二氮杂三环癸烷环上的取代基,这些化合物对δ阿片受体的选择性高于对μ和κ受体的选择性。 在新化合物中,与SNC-80相比,1Aa具有更有趣的生物学特性,具有更高的δ亲和力和选择性。使用离体(分离的小鼠输精管)和体内(甩尾)测定法确认了1Aa的δ受体激动剂谱和抗伤害感受活性。
