Dihydrogenistein
IUPAC 名称
5,7-dihydroxy-3-(4-hydroxyphenyl)-3,4-dihydro-2H-1-benzopyran-4-one
描述
Dihydrogenistein is a metabolite of the soy isoflavone genistin (the glycoside conjugate of genistein) by intestinal bacteria. Isoflavones are one of the three major classes of phytoestrogens; phytoestrogens are a diverse group of plant-derived compounds that structurally and functionally mimic mammalian estrogen. The isoflavone genistin is one of the most prevalent in soy foods. They are biologically inactive; once ingested, they are cleaved by glucosidases to "aglycones", genistein. Epidemiological studies have associated high soy intake with a lowered risk for certain hormone-dependent disease. Many studies reveal that the incidence of prostate cancer and breast cancer is much lower in Asian people in comparison to people from the West and, and the prevailing contribution to this difference has been attributed to the diet. Soy foods and soy-derived products which contain abundant isoflavones are consumed in large quantities by Asian people. In vitro, isoflavone metabolites have dual functions: they can act as an estrogenic agonist or antagonist depending on the estrogen concentration. (PMID: 17499260, 16965913) [HMDB]. Dihydrogenistein is a biomarker for the consumption of soy beans and other soy products.
