Research Overview

GLP-1(7-36) amide

One of the best-studied gut hormones, with strong evidence for incretin biology and appetite regulation. Native GLP-1 is rapidly degraded by DPP-4, which is why its biology is central to endocrine and metabolic pharmacology.

Endomorphin-1

Endomorphin-1 is a key research peptide in studies of endogenous mu-opioid signaling and spinal analgesia. Like other peptide analgesics, its main translational hurdles are enzymatic instability, limited oral bioavailability, and delivery across barriers.
