Larazotide CAS NO.258818-34-7
<p>Larazotide is a synthetic octapeptide zonulin receptor antagonist, structurally derived from the zonula occludens toxin (Zot), designed to regulate intestinal epithelial tight junctions. It functions as a first-in-class intestinal barrier protector, specifically targeting the paracellular pathway to reduce gut permeability. This research-grade peptide is primarily utilized in preclinical studies investigating aut…

| Biological Activity | Larazotide is a synthetic peptide that acts as an intestinal permeability modulator. It has been shown to inhibit the paracellular pathway in the intestinal epithelium, reducing the passage of harmful substances from the gut lumen into the underlying tissues. In preclinical and clinical studies, it has demonstrated efficacy in improving symptoms associated with various gastrointestinal disorders, such as irritable bowel syndrome and inflammatory bowel diseases, by restoring normal intestinal barrier function. |
| Storage Conditions | Store at - 20°C in a dry and dark place. Protect from light, moisture, and extreme temperatures to maintain product stability. |
| Stock Location | Stock in USA |
| MOQ | 1g |
1.MECHANISM OF ACTION
Larazotide acts as a potent zonulin receptor antagonist, competitively blocking the binding of endogenous zonulin to its receptor on intestinal epithelial cells. By inhibiting this interaction, it prevents the disassembly of tight junction proteins such as occludin and ZO-1, thereby maintaining the integrity of the intestinal barrier. This mechanism effectively reduces paracellular permeability, limiting the translocation of pro-inflammatory antigens and gluten peptides into the lamina propria, which is critical in preventing immune activation in sensitive individuals.
2.PRODUCT INDICATIONS
This product is indicated for research applications focused on celiac disease, autoimmune enteropathies, and conditions characterized by increased intestinal permeability. It serves as a key tool for investigating the role of the zonulin pathway in Type 1 diabetes, inflammatory bowel disease (IBD), and systemic inflammatory responses. Researchers utilize Larazotide to explore adjuvant therapies that target barrier function restoration in patients with persistent symptoms despite dietary modifications.
3.CLINICAL EFFICACY OF PRODUCT
In clinical research settings, Larazotide has demonstrated efficacy in reducing gastrointestinal symptom severity and improving quality-of-life scores in subjects with celiac disease on a gluten-free diet. Studies have shown it can significantly decrease intestinal permeability markers and attenuate gluten-induced immune responses. While earlier phase trials confirmed its ability to mitigate abdominal pain and bloating, its development highlights its potential as a non-dietary intervention for barrier dysfunction-related disorders.
