Abstract

Hericenone C is one of the most abundant secondary metabolites derived from Hericium erinaceus, under investigation for medicinal properties. Here, we report that Hericenone C inhibits the second phase of formalin-induced nociceptive behavior in mice. As the second phase is involved in inflammation, in a mechanistic analysis on cultured cells targeting NF-κB response element (NRE): luciferase (Luc)-expressing cells, lipopolysaccharide (LPS)-induced NRE::Luc luciferase activity was found to be significantly inhibited by Hericenone C. Phosphorylation of p65, which is involved in the inflammatory responses of the NF-κB signaling pathway, was also induced by LPS and significantly reduced by Hericenone C. Additionally, in mice, the number of CD11c-positive cells increased in the paw during the peak of the second phase of the formalin test, which decreased upon Hericenone C intake. Our findings confirm the possibility of Hericenone C as a novel therapeutic target for pain-associated inflammation.
