Firazorexton hydrate (TAK-994)
OX2R agonist
Firazorexton hydrate (TAK-994) is an orally active, brain-penetrant selective agonist of the orexin type 2 receptor (OX2R). It effectively promotes wakefulness by stimulating OX2R signaling, which plays a critical role in regulating the sleep–wake cycle. In preclinical studies, Firazorexton hydrate has demonstrated the ability to alleviate narcolepsy-like symptoms in mouse models, making it a promising therapeutic candidate for sleep disorders such as narcolepsy and excessive daytime sleepiness.
