What is DSIP? DSIP, or Delta Sleep-Inducing Peptide, is a naturally occurring neuropeptide. It was originally isolated from the cerebral venous blood of rabbits during induced sleep, leading to its name. DSIP is a nonapeptide with a unique amino acid sequence, which is thought to penetrate the blood-brain barrier and influence several neurotransmitter systems. DSIP Structure Sequence: Trp-Ala-Gly-Gly-Asp-Ala-Ser-Gly-Glu Molecular Formula: C35H48N10O15 Molecular Weight: 848.824 g/mol PubChem CID: 68816 CAS Number: 62568-57-4 Synonyms: Emideltide, DSIP nonapeptide, Deltaran Research on DSIP Sleep and Circadian Rhythms DSIP's role in sleep regulation is complex. Initial studies suggested it could induce delta wave sleep in rabbits, but subsequent research in humans and other animals has shown mixed results. Its exact mechanism of action in sleep regulation remains unclear, but it may normalize disrupted sleep patterns and potentially aid in treating insomnia. Cardiovascular Health DSIP has shown potential in reducing myocardial oxidative stress and normalizing heart rhythms. It may protect against myocardial infarction by reducing cell death in heart tissues, making it a candidate for further research in heart disease treatment. Neuroprotection and Stress Research indicates that DSIP may have neuroprotective properties, particularly in reducing damage and promoting recovery after ischemic brain injury. It appears to regulate stress response systems within the brain, influencing both physical and psychological reactions to stress. Pain Management DSIP exhibits analgesic properties, possibly through modulation of opioid receptors or other neurotransmitter systems. This makes it a potential candidate for developing new pain management therapies, especially for chronic conditions. Potential in Treating Depression Emerging research suggests that DSIP could play a role in managing depression. It may affect several neurochemical pathways associated with mood regulation and stress response, offering a novel approach to treating depressive disorders. Potential Applications DSIP's diverse effects make it a subject of interest in multiple therapeutic areas, including sleep disorders, chronic pain management, cardiovascular health, and neuropsychiatric conditions like depression. Ongoing research aims to clarify its mechanisms and therapeutic potential further. Product Usage Note: DSIP is provided as a research chemical, intended solely for scientific and educational use.
