Biochanin A is an antiproliferative and anti-inflammatory agent that inhibits iNOS expression and lipopolysacharide (LPS)-induced nitric oxide production in macrophages. Additionally, Biochanin A displays the ability to block phosphorylation of IκBα and p38 MAPK, which prevents NF-κB activation. Furthermore, Biochanin A has been observed to suppress IL-6, IL-1β, and TNF-α production.
