Biochanin A is classified as a phytoestrogen and has putative benefits in dietary cancer prophylaxis.^{[medical citation needed]} It has also been found to be a weak inhibitor of fatty acid amide hydrolase in vitro.^[2]

Metabolism

The enzyme biochanin-A reductase uses dihydrobiochanin A and NADP⁺ to produce biochanin A, NADPH, and H⁺. The enzyme isoflavone-7-O-beta-glucoside 6"-O-malonyltransferase uses malonyl-CoA and biochanin A 7-O-β-D-glucoside to produce CoA and biochanin A 7-O-(6-O-malonyl-β-D-glucoside).
