DSIP

DSIP is a nonapeptide with the sequence Trp-Ala-Gly-Gly-Asp-Ala-Ser-Gly-Glu that demonstrates sleep-promoting activity in research models. This research compound is utilized in studies investigating sleep regulation mechanisms, circadian rhythm biology, and neurological signaling pathways related to sleep-wake cycles. DSIP is classified as a neuropeptide for sleep research applications.
