Research Overview

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.

Cotadutide

Phase 2 studies reported dose-dependent weight loss and favorable changes in glycemic and liver-related markers. It is one of the most cited synthetic dual-agonist peptides for obesity research.
