A Natural Anti-Periodontitis Agent, Epimedokoreanin B, Inhibits Virulence Activities Of Gingipains From Porphyromonas Gingivalis

Gingipains are potent virulence cysteine proteases secreted by Porphyromonas gingivalis, a major pathogen of periodontitis. We previously reported that epimedokoreanin B inhibits the activities of gingipains. In this report, we show that epimedokoreanin B inhibits the virulence of gingipains-containing P. gingivalis culture supernatants, indicating the potential use of this prenylated flavonoid as a new agent to combat against periodontal pathogens.
