Background

ACT 335827 is a potent and selective antagonist of OXR-1 with IC50 values of 120 and 2300 nM for OXR-1 and OXR-2, respectively [1].

Orexin receptor 1 (OXR-1) is a G-protein coupled receptor for neuropeptide orexin-A and regulates feeding behaviour. OXR-1 is expressed in the hypothalamus.

ACT 335827 is a potent and selective OXR-1 antagonist with Kb values of 41 and 560 nM for OXR-1 and OXR-2, respectively [1].

In the fear-potentiated startle rats, ACT-335827 (300 mg/kg) inhibited fear-induced startle reactions. Also, ACT-335827 (300 mg/kg) significantly reduced stress-induced tachycardia and hyperthermia. In the rat polydipsia model, ACT-335827 (300 mg/kg) inhibited compulsive drinking behavior [1]. In rats exposed to novelty stress, ACT-335827 (100 mg/kg) reduced the tachycardic and pressor by 48% and 32%, respectively [2]. In a diet-induced obesity(DIO) rat model, ACT-335827 increased the level of high-density lipoprotein and water intake. Also, it slightly increased body weight, which suggested that inhibition of OXR-1 had minimal impact in this model [3].
