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.
NPY
NPY has been shown in animal studies to protect neurons from excitotoxic injury and to dampen stress-linked cognitive impairment. It is often discussed as a counterbalance to overactive glutamatergic and stress pathways in the brain.
