SNAP-8- Summary
- Larazotide acetate is an 8-amino acid peptide (Gly-Gly-Val-Leu-Val-Gln-Pro-Gly) derived from Zonula Occludens Toxin (ZOT) of Vibrio cholerae. It paradoxically acts as a ZOT antagonist to close tight junctions and reduce intestinal permeability ('leaky gut'). It is the most advanced clinical compound targeting gut permeability directly.
- SNAP-8 is a synthetic octapeptide cosmetic ingredient that reduces the depth of expression lines and wrinkles by competitively inhibiting the SNARE complex involved in acetylcholine release at neuromuscular junctions, providing a topical 'Botox-like' effect.
- Half-Life
- Local gut action; minimal systemic exposure
- N/A — topical application; local effect duration depends on formulation
