Biochem/physiol Actions Biochanin A is an isoflavone phytoestrogen found in red clover (Trifolium pratense) that is a selective agonist at ER-β estrogen receptors, and may have chemopreventive efficacy against breast cancer. In line with its low activity at ER-α estrogen receptors, it is essentially devoid of uterotrophic activity. Biochanin A is also a ligand for the aryl hydrocarbon receptor (AhR). It reduces arterial resistance and enhances microcirculation perhaps via effects on potassium and/or calcium ion channels. Induction of sulfotransferases for xenobiotic detoxification has been proposed as a mechanism of its cancer preventive effects.1 Other Notes Tandem Mass Spectrometry data independently generated by Scripps Center for Metabolomics is available to view or download in PDF.
