SNAP-8 (Acetyl Octapeptide-3) is a synthetic eight-amino-acid peptide (Ac-Glu-Glu-Met-Gln-Arg-Arg-Ala-Asp-NH2) that mimics the N-terminal end of the SNAP-25 protein. Research investigations have focused on its mechanism of competitive inhibition of SNARE complex assembly, which is essential for synaptic vesicle fusion and neurotransmitter release at the neuromuscular junction.
In research settings, SNAP-8 has been studied for its effects on acetylcholine release modulation through destabilization of the SNARE complex. Published investigations have examined its topical bioavailability and penetration characteristics, with clinical studies reporting measurable effects on dynamic skin parameters. Research has explored its N-terminal acetylation and C-terminal amidation modifications, which enhance enzymatic resistance and stability compared to unmodified peptide sequences.
Supplied as a lyophilized powder for reconstitution. Intended for research purposes only.
