Research Overview

Teduglutide

Teduglutide has robust clinical evidence showing improved intestinal absorption and reduced parenteral nutrition dependence in short bowel syndrome. Its mechanism, via GLP-2 receptor activation, makes it highly relevant to mucosal healing and intestinal adaptation research.

Met-enkephalin

Met-enkephalin has been extensively used in receptor pharmacology and nociception studies to map mu and delta opioid biology. The main limitation in translational work is very short half-life from peptidase cleavage and poor systemic stability.
