Seltorexant is an orally active, high-affinity, and selective OX2R antagonist with a pKi value of 8.1 for rat OX2R [1]. Seltorexant can cross the blood-brain barrier (BBB) and bind to OX2R, which selectively block OX2R to initiate and prolong sleep [2]. Seltorexant has been widely used to shorten the latency of rapid eye movement (REM) sleep in rats and to prolong the duration of REM sleep [3].
In vivo, Seltorexant treatment via a single subcutaneous injection at a dose of 10mg/kg for 30 minutes acutely reduced responding for sucrose under both sleep deprivation and sleep recovery conditions[4]. Intraperitoneal injection of a 10mg/kg/day dose of Seltorexant for 5 days can increase the anxiety-like behavior in male mice[5].

| Animal experiment [1]: | |
Animal models | Male Sprague-Dawley rats |
Preparation Method | Male Sprague-Dawley rats (350-450g) were maintained in a controlled environment at 22±3°C and 60% relative humidity under a 12h light/dark cycle, and were given free access to standard rodent nutrition and water. Rats were chronically implanted with telemetric devices for the recording of sleep parameters. Administer 30mg/kg of Seltorexant orally every day for 7 consecutive days, and then analyze the sleep parameters of the rats. |
Dosage form | 30mg/kg/day for 7 days; p.o. |
Applications | Seltorexant treatment maintained the reduced sleep onset and increased sleep duration in rats. |

| General tips | Please select the appropriate solvent to prepare the stock solution according to the
solubility of the product in different solvents; once the solution is prepared, please store it in
separate packages to avoid product failure caused by repeated freezing and thawing.Storage method
and period of the stock solution: When stored at -80°C, please use it within 6 months; when stored
at -20°C, please use it within 1 month. To increase solubility, heat the tube to 37°C and then oscillate in an ultrasonic bath for some time. |
