Research Overview
Plecanatide
Clinical trials show plecanatide improves constipation outcomes with a generally favorable tolerability profile. Like linaclotide, it acts locally in the intestinal lumen via GC-C signaling rather than systemic hormone effects.
GPE
Preclinical studies suggest GPE can reduce neuronal damage and support plasticity-related pathways in the brain. Research interest centers on hippocampal function, which links it to learning and memory paradigms.
