MK-1064 is a selective orexin 2 receptor antagonist (2-SORA) for the research of insomnia.target: 2-SORA [1]In vivo: MK-1064 promotes sleep and increases both rapid eye movement (REM) and non-REM (NREM) sleep in rats at OX2R occupancies higher than the range observed for dual orexin receptor antagonists. MK-1064 increases NREM and REM sleep in dogs without inducing cataplexy. The reference for animal administration is 30 mg/kg. [2]
