What is SNAP-8?
SNAP-8 is a synthetic, N-acetylated octapeptide with the sequence Ac-Glu-Glu-Met-Gln-Arg-Arg-Ala-Asp-NH2 (CAS 868844-74-0; PubChem CID 71587832; molecular formula C42H72N16O15S; molecular weight ~1075.2 g/mol per PubChem). Its sequence is derived from the N-terminal region of SNAP-25, a component of the SNARE protein complex. It is supplied as a high-purity reference compound for biochemical and laboratory research, including in vitro and analytical characterization studies.
How SNAP-8 is studied
In research models, SNAP-8 is described as a structural mimic of the N-terminus of SNAP-25 that may compete for a position within the SNARE complex, the protein assembly involved in vesicle fusion and neurotransmitter release in cellular models. By occupying this position, it is studied as a tool for investigating SNARE-complex assembly and stability. These observations are characterized in preclinical/in vitro and cosmetic-science research contexts only and do not establish any human outcome.
Research areas
- Studied in vitro as a tool for investigating SNARE-complex assembly and SNAP-25 interaction pathways
- Investigated in cosmetic-science research models involving peptides and topical formulation systems
- Used as an analytical reference standard for method development (e.g., LC-MS/MS quantification of peptides in formulations)
- Examined in structure-activity research alongside related acetylated peptides
- Studied for peptide stability and physicochemical characterization in laboratory settings
These describe laboratory/preclinical research only. No therapeutic, medical, or efficacy claims are made.
