Opioid receptors play an important role in both behavioral and mood functions. Based on the structural modification of LY2456302, a series of aminobenzyloxyarylamide derivatives were designed and synthesized as κ opioid receptor antagonists. The κ opioid receptor binding ability of these compounds were evaluated with opioid receptors binding assays. Compounds 1a-d showed high affinity for κ opioid
阿片受体在行为和情绪功能中均起重要作用。基于LY2456302的结构修饰,设计合成了一系列氨基苄氧基芳基酰胺衍生物作为κ阿片受体拮抗剂。这些化合物的κ阿片受体结合能力用阿片受体结合测定法评估。化合物1a-d对κ阿片受体具有高亲和力。特别是对于化合物1c,与(±)LY2456302相比,κ阿片受体的结合具有显着的Ki值15.7 nM,对μ和δ阿片受体的选择性更高。此外,化合物[1c]在[35S]GTP-γ-S功能测定中也显示出有效的κ拮抗剂活性,κIC50 = 9.32 nM。还研究了代表性化合物作为抗抑郁药的潜在用途。
