Oxytocin- 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.
- Oxytocin is a 9-amino acid neuropeptide produced in the hypothalamus with diverse roles in social bonding, trust, stress reduction, and sexual function. Exogenous administration is used therapeutically to improve social cognition, reduce anxiety, and enhance intimacy.
- Half-Life
- Local gut action; minimal systemic exposure
- ~3–5 minutes (IV); ~30–60 minutes (intranasal, CNS effects persist longer)
- Admin Route
- Oral
