Synthesis of D6-daidzein

Journal of Labelled Compounds and Radiopharmaceuticals, 2000
Daidzein, an isoflavone abundant in soy, has various interesting biological properties that have been ascribed potential beneficial effects on human health. The study of these properties and effects of daidzein in general requires that an isotopically labeled reference compound is available for quantitative measurements.

Daidzein and genistein content of fruits and nuts

The Journal of Nutritional Biochemistry, 2000
Dietary phytoestrogens such as the isoflavones daidzein and genistein are thought to protect against chronic diseases that are common in Western societies, such as cancer, osteoporosis, and ischemic heart disease. In addition, there are concerns regarding the deleterious effects of hormone-like compounds, especially with respect to the development of ...

Chemical Synthesis of [¹³C]Daidzein

Journal of Medicinal Food, 1999
Pharmacokinetic and metabolic studies of phytoestrogens of the isoflavone class have been hampered by the lack of suitable stable-isotope-labeled analogs. A method for preparation of a [(13)C]-labeled analog of daidzein is described. [2-(13)C]Daidzein was synthesized by reaction of [(13)C]diethoxydimethylaminomethane with 2,4-dihydroxybenzoin.

Extraction and Quantification of Daidzein and Genistein in Food

Analytical Biochemistry, 1998
A simple analytical method has been developed for routine quantification of a broad range of concentrations of the isoflavones daidzein and genistein in food. The synthetic glucosides daidzin and genistin were used as internal standards, combined with each food prior to extraction.

Glycosylation of daidzein by the Eucalyptus cell cultures

Phytochemistry, 2008
The sequential glycosylation of a soybean isoflavone, daidzein, with cultured suspension cells of Eucalyptus perriniana and cyclodextrin glucanotransferase was studied. Daidzein was converted into two glycosylation products, daidzein 7-O-beta-D-glucopyranoside (39%) and daidzein 7-O-[6-O-(beta-D-glucopyranosyl)]-beta-D-glucopyranoside (beta ...

Daidzein promotes milk synthesis and proliferation of mammary epithelial cells via the estrogen receptor α-dependent NFκB1 activation

Animal Biotechnology, 2020
Isoflavones possess a wide range of physiological effects. However, it is still unclear whether isoflavones can promote milk synthesis in mammary gland.

Metabolites of Daidzein and Genistein and Their Biological Activities

Journal of Natural Products, 1995
A number of metabolites of daidzein and genestein have been synthesized and their biological activities determined. Equol [3], 5,7,4'-trihydroxyisoflavan [5], 4,7,4'-trihydroxyisoflavan [6], dihydrodaidzein [8], and dihydrogenistein [9] were synthesized either from daidzein [1] or genistein [2] by hydrogenation.

Synthesis of [3,4,8-13C3]daidzein

Tetrahedron, 2004
Abstract The biological effects of the soy isoflavones have attracted considerable interest in recent years leading to numerous studies on dietary intake and epidemiology. Such studies require accurate and reproducible analytical methods. Herein we report the first synthesis of a multiply 13C-labelled daidzein derivative, [3,4,8-13C3]daidzein, which ...

Metabolism of Daidzein and Genistein by Intestinal Bacteria

Journal of Natural Products, 1995
The isoflavones daidzein [1] and genistein [2] were fermented with human fecal bacteria under anaerobic conditions. Dihydrodaidzein [3], benzopyran-4,7-diol,3-(4-hydroxyphenyl) [4], and equol [5] were isolated from the fermentation broth of 1. Only one metabolite, dihydrogenistein [6], was isolated and characterized from the fermentation broth of 2 ...
