A novel series of melanin-concentrating hormone (MCH1) receptor antagonists based on combining key fragments from the high-throughput screening (HTS) hits compound 2 (SNAP 7941) and compound 5 (chlorohaloperidol) are described. The resultant analogs, exemplified by compounds 11a-11h, 15a-15h, and 16a-16g, were evaluated in in vitro and in vivo assays for their potential in treatment of mood disorders. From further SAR investigations, N-(3-{1-[4-(3,4-difluorophenoxy)benzyl]-4-piperidinyl}-4-methylphenyl)-2-methylpropanamide (16g, SNAP 94847) was identified to be a high affinity and selective ligand for the MCH1 receptor. Compound 16g also shows good oral bioavailability (59%) and exhibits a brain/plasma ratio of 2.3 in rats. Compound 16g showed in vivo inhibition of a centrally induced MCH-induced drinking effect and exhibited a dose-dependent anxiolytic effect in the rat social interaction model.
描述了一系列新型的黑色素浓缩激素（MCH1）受体拮抗剂，这些拮抗剂是通过将高通量筛选（HTS）命中化合物2（SNAP 7941）和化合物5（氯氟哌啶醇）的关键片段组合而成。以化合物11a - 11h、15a - 15h和16a - 16g为例的所得类似物，在体外和体内试验中评估了它们治疗情绪障碍的潜力。通过进一步的构效关系（SAR）研究，确定N -（3 - {1 - [4 -（3,4 - 二氟苯氧基）苄基] - 4 - 哌啶基} - 4 - 甲基苯基）- 2 - 甲基丙酰胺（16g，SNAP 94847）是MCH1受体的高亲和力和选择性配体。化合物16g在大鼠中还显示出良好的口服生物利用度（59%），并且脑/血浆比为2.3。化合物16g在体内抑制了中枢诱导的MCH诱导的饮水效应，并在大鼠社交互动模型中表现出剂量依赖性的抗焦虑作用。
