clinical, suggests that the orexin system is profoundly implicated in sleep disorders. In particular, modulation of the orexin receptors activation by appropriate antagonists was proven to be an efficacious strategy for the treatment of insomnia in man. A novel, drug-like bis-amido piperidine derivative was identified as potent dual OX1 and OX2 receptor antagonists, highly effective in a pre-clinical
下丘脑肽orexin-A和orexin-B是两种G蛋白偶联受体,即OX 1和OX 2受体的有效激动剂。这些受体在大鼠脑中分布广泛,尽管存在差异。特别是,OX 1受体在整个下丘脑中高度表达,而OX 2受体在整个下丘脑中都高度表达。受体主要位于腹后核。大量令人信服的证据(包括临床前和临床证据)表明,食欲素系统与睡眠障碍密切相关。特别地,通过适当的拮抗剂调节食欲素受体激活被证明是治疗人失眠的有效策略。一种新颖的,类似药物的双酰胺基哌啶衍生物被确定为有效的双重OX 1和OX 2受体拮抗剂,在临床前睡眠模型中非常有效。
