Larazotide acetate
Based on 4 publication(s) in Google Scholar
Larazotide acetate is a peptide which is an orally active zonulin antagonist. Larazotide acetate 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 acetate can be used for the research of celiac disease and infection.

Paracellular permeability[1]
Larazotide acetate (1-100 μM; 5 d) affects Vero cell growth[1]. Larazotide acetate (1-100 μM; 3 d) shows antiviral activity to varicella-zoster virus (VZV) with EC50s of 44.14 and 59.06 μM for strain OKA and 07-1, respectively[1]. Larazotide acetate (1 and 3 mM; 72 h) inhibits cytokine-induced tight junction permeability in Caco-2 cells[2]. Larazotide acetate (12.5 mM; 1 h) inhibits PTG-induced ZO-1 redistribution and actin cytoskeletal rearrangement in IEC6 cells[2].
