Cetylpyridinium chloride

Cetylpyridinium chloride, a cationic quaternary ammonium compound, is an anti-bacterial agent with broad-spectrum activity. Cetylpyridinium chloride is an effective anti-HBV capsid assembly inhibitor with an IC50 of 2.5 μM. Cetylpyridinium chloride is used in pesticides and various types of mouthwashes, and other personal care products.

How to use

In Vitro:

Cetylpyridinium chloride interacts with dimeric viral nucleocapsid protein (known as core protein or HBcAg) specifically. Compared with other HBV inhibitors, Cetylpyridinium chloride achieves significantly better reduction of HBV particle number in HepG2.2.15 cell line. Cetylpyridinium chloride inhibits capsid assembly and leads to reduced HBV biogenesis. Cetylpyridinium chloride is a safe antimicrobial agent with broad-spectrum activity for preventing biofilm formation and gingivitis.

In Vivo:

Cetylpyridinium chloride (30 μg/kg; intramuscular injection; daily; for 3 days; male C57BL/6 mice) treatment inhibits HBV replication in mouse hydrodynamic model system.
