SNAP-8
Also known as Acetyl octapeptide-3, Acetyl glutamyl heptapeptide-3
An eight-amino-acid peptide developed in cosmetic science, studied for its effect on the signalling behind expression lines.
What it is
SNAP-8 is a synthetic octapeptide modelled on a section of SNAP-25, a protein involved in the release of signalling molecules at the neuromuscular junction. It was developed for topical cosmetic research, which makes it unusual in this catalogue: most compounds here come from clinical or preclinical pharmacology rather than the cosmetic field.
What published research examines
- SNARE complex formation in cell models
- Neurotransmitter release at the neuromuscular junction
- Expression-line research in topical formulation studies
- Comparison with related cosmetic peptides in the same family
Where the research stands
The SNAP-8 literature comes mainly from cosmetic-science research and formulation studies, much of it produced by or for ingredient suppliers, so independent work is limited.
