RESEARCH COMPOUNDS

Delta Sleep-Inducing Peptide (DSIP) is a naturally occurring nonapeptide (Trp-Ala-Gly-Gly-Asp-Ala-Ser-Gly-Glu) first isolated from cerebral venous blood in research models during the 1970s. It has been extensively characterised as a reference compound in studies examining central nervous system peptide signalling, neuromodulatory pathway interactions, and hypothalamic regulatory dynamics. DSIP has been investigated across a wide range of in-vitro and preclinical research contexts, with particular interest in its structural interactions with peptidergic receptor systems. Its nonapeptide sequence and endogenous origin make it a well-referenced compound in neuroscience research literature.
