1.MECHANISM OF ACTION

Orexin A exerts its biological effects through high-affinity binding to two G-protein-coupled receptors (GPCRs): orexin receptor 1 (OX₁R) and orexin receptor 2 (OX₂R), which are widely distributed in the central nervous system, particularly in brain regions associated with sleep regulation, appetite control, and reward processing. The conserved sequence and intact disulfide bonds of Orexin A ensure stable binding to these receptors across bovine, human, mouse, and rat species.

2.PRODUCT INDICATIONS

Sleep-wake research: Investigation of OX₁R/OX₂R-mediated sleep regulation pathways, serving as a standard ligand for studying sleep disorders (e.g., narcolepsy) in mouse, rat, and translational human models.

Neuroscience research: Study of neuronal excitability, neurotransmitter release, and reward pathway modulation across bovine, human, mouse, and rat species.

Metabolic research: Evaluation of Orexin A’s role in appetite stimulation and energy metabolism regulation, supporting studies on obesity and metabolic syndrome.

3.CLINICAL EFFICACY OF PRODUCT

Orexin A (CAS 205640-90-0) is widely utilized in preclinical research, with proven efficacy across bovine, human, mouse, and rat in vitro and in vivo models. In mouse and rat sleep disorder models, it effectively modulates sleep-wake cycles by activating OX₂R, reversing sleep fragmentation and promoting wakefulness—providing valuable insights into narcolepsy and insomnia pathologies.
