Research Overview
DADLE
DADLE has been studied for analgesic, neuroprotective, and receptor-selective opioid effects in animal and tissue models. It remains important as a mechanistic probe because it is more stable than endogenous enkephalins but still peptide-like in its delivery constraints.
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.
