DSIP has been described as a sleep-promoting substance. There is a modulating effect on sleep and wake functions with a greater activity in circumstances where sleep is disturbed. There are minimal effects in healthy subjects who are not suffering from sleep disturbance.

Delta sleep-inducing peptide, abbreviated DSIP, is a neuropeptide that when infused into the mesodiencephalic ventricle of recipient rabbits induces spindle and delta EEG activity and reduced motor activities. Its aminoacid sequence is TRP-ALA-GLY-GLY-ASP-ALA-SER-GLY-GLU However, the gene is unknown[citation needed], raising serious questions regarding the actual existence of this peptide in nature.

DSIP is an endogenous peptide composed of 9 amino acids. Its chemical structure is pyroglutamyl-alanyl-aspartyl-glutamyl-threonyl-glycyl-glutamyl-alanyl-leucyl-amide. It exists naturally in the human body, is mainly secreted by certain neurons in the brain, and can also be prepared by artificial synthesis.

DSIP mainly acts on the central nervous system, binds to specific receptors, regulates the release of neurotransmitters and the activity of neurons, and thus affects the sleep - wake cycle. It is believed to promote the brain to enter a sleep state, especially increasing the duration and depth of slow - wave sleep.

For people with sleep disorders, such as insomniacs, DSIP can help them fall asleep more easily, extend their sleep time, improve the depth and quality of sleep, reduce the number of awakenings at night, and make their sleep more stable and comfortable.

As an endogenous peptide, DSIP is a substance produced by the human body itself, with good biocompatibility and low immunogenicity. Therefore, under reasonable use, compared with traditional sleep medications, DSIP may have higher safety and is less likely to cause drug dependence and adverse reactions.
