SNAP-8

A synthetic octapeptide that mimics the N-terminal segment of SNAP-25, a component of the SNARE complex involved in neurotransmitter vesicle docking at the neuromuscular junction. Studied in cosmetic dermatology as a topical "neuro-Botox" for reducing expression lines by attenuating acetylcholine release at neuromuscular junctions in facial muscles. Extended version of acetyl hexapeptide-3 (Argireline).
