We report the structure−activity relationships, design, and synthesis of the novel cannabinoid type 1 (CB1) receptor antagonist 3a (CP-945,598). Compound 3a showed subnanomolar potency at human CB1 receptors in binding (Ki = 0.7 nM) and functional assays (Ki = 0.12 nM). In vivo, compound 3a reversed cannabinoid agonist-mediated responses, reduced food intake, and increased energy expenditure and fat
我们报告了新型
大麻素类型1(CB 1)受体拮抗剂3a(CP-945,598)的结构活性关系,设计和合成。化合物3a在结合(K i = 0.7 nM)和功能分析(K i = 0.12 nM)中对人CB 1受体表现出亚纳摩尔效价。在体内,化合物3a逆转了
大麻素激动剂介导的反应,减少了食物的摄入,并增加了啮齿动物的能量消耗和脂肪氧化。
