Research Overview
DPDPE
DPDPE is widely cited in opioid pharmacology because it helped establish the functional role of delta-opioid receptors in pain control. Its constrained structure is also used to explore how peptide cyclization changes potency, stability, and tissue selectivity.
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.
