DSIP (Delta Sleep-Inducing Peptide)

Peptide

DSIP (Delta Sleep-Inducing Peptide) is a naturally occurring nonapeptide (Trp-Ala-Gly-Gly-Asp-Ala-Ser-Gly-Glu) first isolated from rabbit brain in 1977. It has been studied for sleep regulation, stress protection, pain modulation, and substance withdrawal. While demonstrating promise in various clinical applications including opioid and alcohol withdrawal, its mechanisms remain incompletely understood, and human clinical data shows mixed results for sleep induction.
