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.

Noopept

Noopept has been reported to increase NGF/BDNF-related signaling and improve performance in tasks involving learning and recall. Evidence includes preclinical studies and small human studies, but the overall literature is still modest compared with mainstream cognitive drugs.
