Common Name

5,7-Dihydroxy-4-Methylisoflavone

Description

Biochanin A, also known as olmelin or pratensol, belongs to the class of organic compounds known as 4'-o-methylisoflavones. These are isoflavones with methoxy groups attached to the C4' atom of the isoflavone backbone. Thus, biochanin a is considered to be a flavonoid lipid molecule. 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). The enzyme biochanin-A reductase uses dihydrobiochanin A and NADP+ to produce biochanin A, NADPH, and H+. Biochanin A is an O-methylated isoflavone. Biochanin A is a very hydrophobic molecule, practically insoluble (in water), and relatively neutral. Outside of the human body, Biochanin A is found, on average, in the highest concentration within a few different foods, such as milk (cow), peanuts, and soy beans and in a lower concentration in beers. Biochanin A has also been detected, but not quantified in, several different foods, such as lingonberries, savoy cabbages, garlics, garden rhubarbs, and red rices. This could make biochanin a a potential biomarker for the consumption of these foods. Biochanin A is classified as a phytoestrogen and has putative benefits in dietary cancer prophylaxis. It is a natural organic compound in the class of phytochemicals known as flavonoids. Biochanin A is a potentially toxic compound. It has also been found to be a weak inhibitor of fatty acid amide hydrolase in vitro. 5,7-Dihydroxy-4-Methylisoflavone was first documented in 2006 (PMID: 16903077). Biochanin A can be found in red clover in soy, in alfalfa sprouts, in peanuts, in chickpea (Cicer arietinum) and in other legumes (PMID: 18565930) (PMID: 16651441) (PMID: 16598420).
