Research Overview

Arenicin-1

Marine annelid peptide with strong preclinical antibacterial activity and a stable structural motif that is useful for peptide engineering.

Larazotide

Clinical and translational studies suggest larazotide can reduce antigen passage across the epithelium and improve gut barrier function. It is one of the better-known peptides for intestinal permeability and barrier-focused gastrointestinal therapy.
