使用阿片类药物治疗疼痛虽然在很大程度上有效,但受到有害副作用的限制,包括镇痛耐受性、身体依赖性和欣快感,这可能导致阿片类药物滥用。研究表明,具有 μ-阿片受体 (MOR) 激动剂/δ-阿片受体 (DOR) 拮抗剂特性的化合物可减少或消除其中一些副作用,包括耐受性和依赖性的发展。在此我们报告了一系列基于四氢喹啉的拟肽的合成和药理学评价,这些肽模拟物在 C-8 位有取代。相对于我们没有 C-8 取代的主要拟肽,该系列提供了 DOR 亲和力的增加,并在 MOR 和 DOR 结合亲和力方面提供了更大的平衡。而且,在 C-8 处具有羰基部分的化合物显示出所需的 MOR 激动剂/DOR 拮抗剂特征,而烷基取代引起适度的 DOR 激动作用。该系列中的几种化合物在体内产生强大的镇痛作用,并在小鼠腹膜内给药后显示镇痛活性超过 2 小时。

Novel chroman and tetrahydroquinoline ureas were synthesized and evaluated for their activity as TRPV1 antagonists. It was found that aryl substituents on the 7- or 8-position of both bicyclic scaffolds imparted the best in vitro potency at TRPV1. The most potent chroman ureas were assessed in chronic and acute pain models, and compounds with the ability to cross the blood-brain barrier were shown to be highly efficacious. The tetrahydroquinoline ureas were found to be potent CYP3A4 inhibitors, but replacement of bulky substituents at the nitrogen atom of the tetrahydroisoquinoline moiety with small groups such as methyl can minimize the inhibition.
