Catalog Number: 3603
Alternate Names: Kempferol
Chemical Name: 3,5,7-Trihydroxy-2-(4-hydroxyphenyl)-4H-1-benzopyran-4-one
Biological Activity
Naturally occurring flavonoid found in Gingko biloba and red wines that activates the mitochondrial Ca2+ uniporter (EC50 = 7 μM). Induces caspase-9-mediated apoptosis in a variety of 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.
