1.MECHANISM OF ACTION
Histatin 3 (H3) exerts its antimicrobial activity by disrupting microbial membranes through electrostatic interactions and pore formation, leading to cell lysis and death. It also exhibits immunomodulatory functions, such as promoting wound healing and modulating inflammatory responses in host tissues.
2.PRODUCT INDICATIONS
This peptide is used in research focused on oral infections (e.g., dental caries, periodontitis), skin infections, wound healing, and antimicrobial drug development. It is also applied in studies of biofilm formation, host‑microbe interactions, and the design of peptide‑based therapeutic agents.
3.CLINICAL EFFICACY OF PRODUCT
Preclinical studies have demonstrated that Histatin 3 (H3) effectively reduces bacterial and fungal loads in oral and dermal infection models, accelerates wound closure, and enhances tissue repair. These findings support its potential as a lead compound for developing topical or oral formulations in clinical oral‑health and dermatological applications.
