One compound. One research record.

DSIP (Delta Sleep-Inducing Peptide) is a synthetic nonapeptide (Trp-Ala-Gly-Gly-Asp-Ala-Ser-Gly-Glu) first isolated from rabbit cerebral venous blood by the Schoenenberger-Monnier group in 1977. It was originally characterized as a candidate sleep-promoting factor.

Published research has examined DSIP’s interaction with blood-brain barrier transport mechanisms, hypothalamic-pituitary signaling, and circadian regulation pathways. Its full mechanism of action and receptor profile remain an active area of investigation.
