DSIP is a nonapeptide first isolated by the Schoenenberger–Monnier group from the cerebral venous blood of rabbits in which sleep had been induced; it is named for the delta-wave sleep reported in that work. It has been studied in animals and in small clinical studies, including on drug-withdrawal syndromes.

Regulatory status
No approval as a medicine was found. In July 2026 an FDA advisory committee voted 6–7 against adding emideltide to the 503A bulks list.
