YNT-185（Cat No.:I044503）is a selective, small-molecule agonist of the orexin 2 receptor (OX2R), a G protein-coupled receptor involved in regulating wakefulness, arousal, and energy homeostasis. By specifically activating OX2R, YNT-185 promotes wake-promoting signaling pathways in the central nervous system, making it a valuable tool for studying sleep-wake mechanisms and potential treatments for sleep disorders such as narcolepsy. It has demonstrated efficacy in preclinical models by increasing locomotor activity and reducing sleep episodes. YNT-185 contributes to the development of orexin-based therapeutics targeting hypersomnia and related neurological conditions.
