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.
Histatin-5
Histatin-5 is a major salivary defense peptide that can kill Candida species and influence oral microbial communities. It is also investigated for wound-healing and xerostomia-associated oral infection models.
