Larazotide Usage And Synthesis

Uses

Larazotideis a peptide which is an orally active zonulin antagonist. Larazotide shows antiviral activity to varicella-zoster virus (VZV) with EC50s of 44.14 and 59.06 μM for strain OKA and 07-1, respectively. Larazotide can be used for the research of celiac disease and infection[1][2].

Definition

ChEBI: Larazotide is an oligopeptide.

in vivo

Larazotide (250 μg; i.p. twice a week for 7 weeks) inhibits intestinal permeability in gluten-sensitive transgenic mice[1].

Animal Model:HLA-HCD4/DQ8 double transgenic mice[2]
Dosage:250 μg
Administration:Intraperitoneal injection; 250 μg twice a week for 7 weeks
Result:Improved barrier function parameters and reduced macrophage counts in the lamina propria to control levels.
