DSIP
C₃₅H₄₈N₁₀O₁₅
Key Research Findings
- Isolated from the thalamus during slow-wave (delta) sleep, giving it its name.
- Shown to reduce stress-induced physiological responses in multiple animal models.
- Demonstrates analgesic properties potentially linked to opioidergic system modulation.
- Implicated in circadian rhythm regulation via its influence on cortisol and melatonin secretion timing.
Overview
DSIP (Delta Sleep-Inducing Peptide) is an endogenous neuropeptide first isolated from rabbit thalamic venous blood during electrically induced slow-wave sleep. It is studied for its role in sleep regulation, stress modulation, and as a potential research tool for circadian rhythm investigations.
Mechanism of Action
DSIP is thought to act on multiple neurotransmitter systems including serotonergic, GABAergic, and opioidergic pathways. It appears to modulate corticotropin-releasing hormone (CRH) and ACTH secretion, linking sleep and HPA axis regulation. Its sleep-promoting effects may involve direct action on thalamic and hypothalamic nuclei.
Research Effects
Sleep Regulation
Extensive ResearchNamed for its established role in delta (slow-wave) sleep induction; multiple studies confirm EEG evidence of sleep architecture modification.
Stress Reduction
Moderate ResearchResearch shows attenuation of stress biomarkers and normalisation of HPA axis activity in chronic stress models.
Analgesic
Moderate ResearchStudies indicate DSIP reduces pain responses, with suggested mechanisms involving opioidergic pathways.
Growth Hormone Release
Preliminary ResearchSome research suggests modest stimulation of GH secretion, though evidence remains inconsistent.

Semax
Semax is a heptapeptide analogue of the adrenocorticotropic hormone (ACTH 4–10) developed in Russia. Unlike its parent hormone, Semax has been engineered to retain cognitive and neuroprotective effects while completely eliminating steroidogenic activity, making it a focused nootropic research compound.

Selank
Selank is a synthetic heptapeptide analogue of the endogenous tetrapeptide tuftsin, developed at the Institute of Molecular Genetics in Russia. It is studied primarily for its anxiolytic and nootropic properties, and is notable for lacking the sedative and dependence-forming effects of conventional anxiolytics.
