The orexin system consists of two G‐protein‐coupled receptors, the orexin 1 and orexin 2 receptors, widely expressed in diverse regions of the brain, and two peptide agonists, orexin A and orexin B, which are produced in a small assembly of neurons in the lateral hypothalamus. The orexin system plays an important role in the maintenance of wakefulness. Several compounds (almorexant, SB‐649868, suvorexant)
Orexin系统由两个G蛋白偶联受体,即orexin 1和orexin 2受体,在大脑的各个区域广泛表达,以及两个肽激动剂,orexin A和orexin B,它们是在一小部分神经元中产生的。在下丘脑外侧。食欲素系统在维持觉醒中起着重要作用。几种化合物(almorexant,SB‐649868,suvorexant)已用于治疗原发性失眠的高级临床试验中。ACT-462206是一种新型的,有效的,选择性的双重orexin受体拮抗剂(DORA),可抑制orexin肽对orexin 1和2受体的刺激作用。在大鼠和狗的脑电图/肌电图(EEG / EMG)实验中,它可减少清醒并增加非快速眼动(non-REM)和REM睡眠,同时保持自然睡眠结构。ACT-462206在大鼠中显示出类似抗焦虑的特性,而不会影响认知和运动功能。因此,它是治疗失眠的潜在候选者。
