Acetyl Octapeptide-3
Neurotransmitter Inhibitor
Acetyl Octapeptide-3 (SNAP-8) is an 8-amino acid extension of Argireline featuring two additional C-terminal residues (Ala-Asp), providing enhanced SNAP-25 competitive inhibition with greater binding efficiency at the SNARE complex. Clinical formulation studies suggest wrinkle depth reductions with regular use. Particularly effective on deep expression lines and forehead creases. Used in premium anti-aging serums and targeted wrinkle treatment concentrates.
Main characteristics
Acetyl Octapeptide-3 shares Argireline’s mechanism of competing with the N-terminal domain of SNAP-25 for integration into the SNARE complex, but the two additional residues improve the fit and duration of competitive binding. It is stable at pH 4.5–7.0 and compatible with most serum and cream bases. Often combined with Argireline for complementary coverage of the SNARE complex inhibition. Produced via SPPS to ≥95% purity (HPLC + MS).
Applications
- Premium anti-wrinkle serums targeting deep expression lines
- Forehead and periorbital wrinkle treatments
- Combination formulas with Argireline for dual-mechanism botox-like effect
- Research on SNARE complex dynamics and neuromuscular peptide inhibitors
