cannabinoid receptor 1 (CB1) and antagonized G protein coupling. This compound demonstrated potent anorectic effects similar to the CB1 antagonist rimonabant that once was marketed for the treatment of obesity, suggesting a new chemical entity for the discovery of antiobesity drugs. To increase structural diversity of this class of CB1 ligands, we designed and synthesized two classes of novel analogues
变构调节剂1-(4-氯苯基)-3-(3-(6-(吡咯烷基-1-基)吡啶-2-基)苯基)脲(PSNCBAM- 1,2)结合了大麻素受体1(CB 1)和拮抗的G蛋白偶联。该化合物表现出有效的厌食作用,类似于曾经出售用于治疗肥胖症的CB 1拮抗剂利莫那班,这为发现抗肥胖药提供了新的化学实体。为了增加这类CB 1配体的结构多样性,我们设计并合成了两类新型类似物,其中2的吡啶环被嘧啶环取代。这些积极地调节了CB 1的结合正构激动剂CP55,940,同时表现出对G蛋白偶联活性的拮抗作用。有趣的是,化合物7d和8d表现出通过β-arrestin介导的ERK1 / 2磷酸化,而正构CP55940则以G蛋白依赖性方式发生。这些可以用作未来CB 1变构调节剂发展的新的先导化合物,它们通过新的机理表现出偏向激动性和潜在的抗肥胖行为。
