DSIP 5mg

Compound Overview

DSIP 5mg is a lyophilized synthetic nonapeptide preparation supplied by Amino Apex for qualified laboratory research. Delta Sleep-Inducing Peptide (DSIP) consists of nine amino acids with the sequence Trp-Ala-Gly-Gly-Asp-Ala-Ser-Gly-Glu (WAGGDASGE). It has been investigated in experimental studies involving sleep-related electrophysiological activity, neurophysiological signaling, and peptide structure–activity relationships. Research involving DSIP has examined its relationship with delta-wave EEG activity, sleep-associated neurobiology, neuroendocrine signaling, and peptide metabolism. Although early experimental findings suggested possible involvement in sleep-related processes, its endogenous biological role, molecular mechanism, and physiological significance remain incompletely established. A 1978 peer-reviewed study published in Pflügers Archiv characterized DSIP's amino-acid sequence, synthesis, and electrophysiological activity in experimental rabbit models. The investigation examined changes in delta-wave and spindle-associated EEG patterns, contributing to early research on the peptide's structural and neurophysiological properties. A subsequent 2006 scientific review published in the Journal of Neurochemistry examined unresolved questions surrounding DSIP's natural occurrence, biological mechanisms, and proposed relationship with sleep regulation. The authors emphasized substantial limitations in the available evidence. These publications provide scientific background and do not establish therapeutic effectiveness or safety for the Amino Apex research material.

Molecular & Structural Research

DSIP consists of 9 amino-acid residues with the sequence:

WAGGDASGE

Three-letter sequence:

Trp-Ala-Gly-Gly-Asp-Ala-Ser-Gly-Glu

Its molecular formula is C₃₅H₄₈N₁₀O₁₅, with an approximate molecular mass of 848.8 g/mol.

DSIP is also known as Emideltide and is associated with CAS Number 62568-57-4.

Experimental comparisons involving DSIP analogues, metabolites, and sequence modifications have made the peptide relevant to structure-function research, peptide metabolism studies, and comparative neuropeptide investigations.

Research Applications

DSIP may be studied in appropriately designed laboratory research involving:

• Neuropeptide characterization
• Sleep-associated neurobiology
• Delta-wave and EEG-related research
• Circadian-rhythm research
• Neurotransmitter-associated pathways
• Neuroendocrine signaling
• Stress-response pathway research
• Peptide structure-function studies
• DSIP analogue research
• Peptide metabolism
• Comparative neuropeptide research
• Analytical peptide characterization

These categories describe areas investigated in scientific literature and do not constitute therapeutic or clinical-use recommendations.

Preclinical Research Context

DSIP has been examined in animal models, biochemical investigations, electrophysiological studies, and limited historical human research.

Experimental work has investigated relationships between DSIP and sleep-stage activity, EEG patterns, circadian processes, neurotransmitter systems, endocrine responses, and stress-associated signaling.

The available literature has not established a single definitive physiological mechanism for DSIP. Its biological significance therefore remains an area of experimental and preclinical investigation, and observations from research systems should not be assumed to establish clinical safety, efficacy, or therapeutic effects.

Analytical Documentation

Amino Apex provides batch-specific analytical documentation for tested lots. Individual lot documentation may include chromatographic purity analysis and other analytical information associated with the tested sample.

Because analytical characteristics may differ by production lot, the Certificate of Analysis for the applicable batch should be used as the source of measured purity and quality-control results.

Refer to the COA panel on this page or the Amino Apex COA Library for available batch documentation.
