About this compound

What DSIP is+

DSIP, delta sleep-inducing peptide, is a synthetic nonapeptide originally isolated from the cerebral venous blood of rabbits during slow-wave sleep induction experiments in the 1970s. Its nine-amino-acid sequence and the unusual presence of a phosphorylated serine residue have made it a persistent subject of neuropeptide and chronobiology research.

Research applications+
  • Sleep–wake cycle and circadian rhythm biochemistry
  • Hypothalamic–pituitary axis and stress-response models
  • Neuropeptide blood–brain barrier transport
  • Oxidative stress response modulation
