Seltorexant, also known as JNJ-42847922 and MIN-202, is a potent OX2R antagonist that has been shown to promote sleep in various species. JNJ-42847922 had an approximate 2-log selectivity ratio versus the human orexin-1 receptor. Ex vivo receptor binding studies demonstrated that JNJ-42847922 quickly occupied OX2R binding sites in the rat brain after oral administration and rapidly cleared from the brain. Seltorexant shows antidepressant and sleep-promoting effects in patients with major depressive disorder. JNJ-42847922 induces somnolence in healthy subjects without residual central effects.
