4018 Daidzein Daidzein (C15H10O4) is a solid with an average molecular weight of 254.24 g/mol. Daidzein belongs to the isoflav-2-enes, a subclass of isoflavonoids within the organic compounds. This exogenous plant metabolite functions as a phytoestrogen, an agonist (PMC3515069), and an inhibitor of DNA-directed DNA polymerase (EC 2.7.7.7). Its industrial applications include use as a softener and conditioner, and it is utilized as an antineoplastic agent (PMC3515069). The compound interacts with twelve recorded protein targets, including the Estrogen receptor (ESR1), Estrogen receptor beta (ESR2), Bile acid receptor (NR1H4), and Aryl hydrocarbon receptor (AHR). Regarding health effects, daidzein has a therapeutic effect on osteoporosis, cancer (PMC5037818), breast cancer (PMC8395949), and prostate cancer (PMC8395949). It is associated with a decrease in endometrial cancer (PMC11303474) and prostate cancer (PMC3134227). Daidzein is found in 19 recorded sources across several sectors. These include electrical and electronic equipment such as batteries, capacitors, cell phones, printed circuit boards, and wires and cables; food, food processing and cookware, specifically food packaging and the preparation of vinegar, wort, and wine or sparkling wine, as well as the treatment of hops; textiles, leather and furnishings, including synthetic textiles and carpets and rugs; drinking water and water supply; healthcare, pharmaceuticals and veterinary products via medical devices; and energy, oil and gas through lubricants. Recorded exposure routes for the compound are oral, inhalation, and touch. 486-66-8 5281708 C15H10O4 White powder. 323°C No indication of carcinogenicity to humans (not listed by IARC). Isoflavones compounds are found in a number of plants, but soybeans and soy products like tofu and textured vegetable protein are the primary food source. Equol represents the main active product of daidzein metabolism, produced via specific microflora in the gut. 2014-08-29T04:47:45Z 2026-05-14T19:30:52Z C10208 28197 2-HYDROXYDAIDZEIN DB13182 true OC1=CC=C(C=C1)C1=COC2=C(C=CC(O)=C2)C1=O C15H10O4 InChI=1S/C15H10O4/c16-10-3-1-9(2-4-10)13-8-19-14-7-11(17)5-6-12(14)15(13)18/h1-8,16-17H ZQSIJRDFPHDXIC-UHFFFAOYSA-N 254.241 254.057908802 Exogenous Solid 2.73 HMDB03312 CHEMBL8145 4445025 Baker, Wilson; Robinson, Robert; Simpson, N.
