Delta sleep-inducing peptide (research neuropeptide)
DSIP
Nonapeptide historically associated with sleep-related and stress-axis signalling; clinical status is not that of a modern licensed hypnotic.
Primary Mechanism of Action
Clinical / Scientific
DSIP was isolated as a sleep-related peptide. Proposed actions include modulation of GABAergic and HPA-axis signalling, but the remains poorly defined compared with modern hypnotics. Treat claims as historical/experimental.
Pathway Targets
Sleep / HPA signalling (incompletely defined)
Scientific explanation
Historical neuropeptide pharmacology.
Pathway Convergence
Clinical / Scientific
Target → pathway → downstream effect → biological consequence. This is a mechanistic map, not a treatment claim.

In Plain Language
DSIP is an old “sleep peptide” from research history. Unlike modern sleep medicines, its exact story is still fuzzy.
