DSIP

Delta Sleep-Inducing Peptide, a nonapeptide

DSIP (Delta Sleep-Inducing Peptide) is classified as a naturally occurring nonapeptide. It appears in the preclinical literature on neurological and sleep-research models, where it has been examined as a laboratory material. This page is background about the molecule as a research material and is not medical guidance and not intended for human or animal use.

Classification and structure

DSIP is a nine-amino-acid peptide (Trp-Ala-Gly-Gly-Asp-Ala-Ser-Gly-Glu) first isolated in studies of sleep-related brain activity, from which its name derives. It is classified as a neuropeptide research material and is structurally unrelated to the GHRH and secretagogue peptide classes.

Areas of research

In the scientific literature this peptide appears across the following research areas.

• Sleep-research models — Investigated in laboratory models examining sleep-related neural activity, the context of its original isolation.
• Neuropeptide research — Appears in studies of central-nervous-system peptide signaling.
• Peptide chemistry — Used in synthesis, stability, and analytical-characterization studies.

As always in this library, describing a compound as “studied in” an area is a statement about where scientific attention has gone — not a claim that it produces any result in humans or animals.
