Biological Activity for Kaempferol

Activates the mitochondrial Ca²⁺ uniporter (EC₅₀ = 7 μM). Induces caspase-9-mediated apoptosis in cancer cell lines via downregulation of polo-like kinase 1 (PLK1) expression. Exhibits antioxidant activity and attenuates osteoclastic bone reabsorption in vitro. Also blocks EGF-induced histone H3Ser¹⁰ phosphorylation in mouse epidermal JB6 C141 cells. Activates transcriptional coactivator with PDZ-binding motif (TAZ) and increases osteoblast differentiation of mesenchymal stem cells while inhibiting adipocyte differentiation. Naturally occurring flavonoid found in Gingko biloba and red wine. Kaempferol has antiviral activity against Japanese encephalitis virus (JEV) in infected BHK21 (EC₅₀ = 21.5 μM). Kaempferol directly inhibits viral replication and protein expression by binding JEV frameshift site RNA (fsRNA). Kaempferol influences frameshift efficiency in virus-infected cells through interfering with a downstream RNA pseudoknot structure. Kaempferol has also been reported to exhibit activity against herpes simplex virus, influenza viruses (H1N1 and H9N2) and hepatitis B virus under in vitro conditions.
