Research Overview
Glucagon-like peptide-2
Native GLP-2 is a key enteric growth factor with rapid degradation by DPP-4. Its therapeutic value is best known through GLP-2 analog development, but the native peptide itself is a real GI-relevant hormone.
Linaclotide
Linaclotide has extensive clinical evidence for chronic idiopathic constipation and IBS-C, with consistent effects on stool frequency and abdominal symptom relief. Its mechanism is local GC-C activation in the gut with minimal systemic exposure.
