Microbial Glycosylation of Daidzein, Genistein and Biochanin A: Two New Glucosides of Biochanin A.

ABSTRACT: Biotransformation of daidzein, genistein and biochanin A by three selected filamentous fungi was investigated. As a result of biotransformations, six glycosylation products were obtained. Fungus Beauveria bassiana converted all tested isoflavones to 4?-O-methyl-7-O-glucosyl derivatives, whereas Absidia coerulea and Absidia glauca were able to transform genistein and biochanin A to genistin and sissotrin, respectively. In the culture of Absidia coerulea, in addition to the sissotrin, the product of glucosylation at position 5 was formed. Two of the obtained compounds have not been published so far: 4?-O-methyl-7-O-glucosyl biochanin A and 5-O-glucosyl biochanin A (isosissotrin). Biotransformation products were obtained with 22%-40% isolated yield.

Genome-wide microarray analysis of normal human fibroblasts in response to kaemferol, daidzein, kaemferol/genistein, and daidzein/genistein

Project description:Establishment of a transcriptomic profile of human cells treated with kaemferol, daidzein, kaemferol/genistein, or daidzein/genistein with particular emphasis on signature of genes coding for enzymes involved in glycosaminoglycan synthesis stands for the present study. The hypothesis tested was that kaemferol, daidzein, kaemferol/genistein, and daidzein/genistein influence expression of some genes, among which are those coding for enzymes required for the synthesis of different GAGs being pathologically accumulated in mucopolysaccharidoses. Results provide important information concerning the extent of action of kaemferol, daidzein, kaemferol/genistein, and daidzein/genistein at the molecular level in terms of modulation of gene expression.

Genistein, daidzein, and resveratrols stimulate PGC-1?-mediated gene expression.

Project description:PGC-1? is a transcriptional co-activator of nuclear receptors such as the estrogen receptor-related receptor (ERR). Transgenic overexpression of PGC-1? in mice increases energy expenditure and suppresses high-fat diet-induced obesity. In this study, we screened various food-derived and natural compounds using a reporter assay system to measure the transcriptional activity of PGC-1?. Soy-derived isoflavones, genistein and daidzein, and several resveratrols activated PGC-1?. Genistein, daidzein, and trans-oxyresveratrol activated ERR-responsive element-mediated reporter activity in the presence of PGC-1?. Stable overexpression of PGC-1? in C2C12 myoblasts increased the expression of medium-chain acyl-CoA dehydrogenase (MCAD), an important enzyme in fatty acid ?-oxidation. Genistein and daidzein increased MCAD mRNA levels and mitochondrial content in PGC-1?-expressing C2C12 cells. These compounds activated ERR/PGC-1? complex-mediated gene expression, and our findings may be a practical foundation for developing functional foods targeting obesity.

Isoflavones, genistein and daidzein, regulate mucosal immune response by suppressing dendritic cell function.

Project description:Lipopolysaccharide (LPS), a component of gram-negative bacterial cell walls, has been shown to have a strong adjuvant effect towards inhaled antigens contributing to airway inflammation. Isoflavones are anti-inflammatory molecules present in abundant quantities in soybeans. We investigated the effect of isoflavones on human dendritic cell (DC) activation via LPS stimulation and subsequent DC-mediated effector cell function both in vitro and in a mouse model of upper airway inflammation. Human monocyte-derived DCs (MDDC) were matured with LPS (or TNF-?) +/- isoflavones (genistein or daidzein). The surface expression levels of DC activation markers were analyzed by flow cytometry. Mature DCs +/- isoflavones were washed and cultured with freshly-isolated allogenic naïve CD4? T cells for 5 days or with autologous natural killer (NK) cells for 2 hours. The percentages of proliferating IFN-?? CD4? T cells and cytokine levels in culture supernatants were assessed. NK cell degranulation and DC cytotoxicity were measured by flow cytometry. Isoflavones significantly suppressed the activation-induced expression of DC maturation markers (CD83, CD80, CD86) and MHC class I but not MHC class II molecules in vitro. Isoflavone treatment inhibited the ability of LPS-DCs to induce IFN-? in CD4? T cells. NK cell degranulation and the percentage of dead DCs were significantly increased in isoflavone-treated DC-NK co-culture experiments. Dietary isoflavones suppressed the mucosal immune response to intra-nasal sensitization of mice to ovalbumin. Similar results were obtained when isoflavones were co-administered during sensitization. These results demonstrate that soybean isoflavones suppress immune sensitization by suppressing DC-maturation and its subsequent DC-mediated effector cell functions.

Metabolism of Daidzein and Genistein by Gut Bacteria of the Class Coriobacteriia.

Project description:The intake of isoflavones is presumed to be associated with health benefits in humans, but also potential adverse effects of isoflavones are controversially discussed. Isoflavones can be metabolized by gut bacteria leading to modulation of the bioactivity, such as estrogenic effects. Especially bacterial strains of the Eggerthellaceae, a well-known bacterial family of the human gut microbiota, are able to convert the isoflavone daidzein into equol. In addition, metabolization of genistein is also described for strains of the Eggerthellaceae. The aim of this study was to identify and investigate gut bacterial strains of the family Eggerthellaceae as well as the narrowly related family Coriobacteriaceae which are able to metabolize daidzein and genistein. This study provides a comprehensive, polyphasic approach comprising in silico analysis of the equol gene cluster, detection of genes associated with the daidzein, and genistein metabolism via PCR and fermentation of these isoflavones. The in silico search for protein sequences that are associated with daidzein metabolism identified sequences with high similarity values in already well-known equol-producing strains. Furthermore, protein sequences that are presumed to be associated with daidzein and genistein metabolism were detected in the two type strains 'Hugonella massiliensis' and Senegalimassilia faecalis which were not yet described to metabolize these isoflavones. An alignment of these protein sequences showed that the equol gene cluster is highly conserved. In addition, PCR amplification supported the presence of genes associated with daidzein and genistein metabolism. Furthermore, the metabolism of daidzein and genistein was investigated in fermentations of pure bacterial cultures under strictly anaerobic conditions and proofed the metabolism of daidzein and genistein by the strains 'Hugonella massiliensis' DSM 101782T and Senegalimassilia faecalis KGMB04484T.

A comparative analysis of genistein and daidzein in affecting lipid metabolism in rat liver.

Project description:Effects of soy isoflavones, genistein and daidzein, on the hepatic gene expression profile and indices for lipid metabolism were compared in rats. In the first experiment (Expt. 1), animals were fed diets containing 2 g/kg of either genistein or daidzein, or a control diet free of isoflavone for 14 days. In the second experiment (Expt. 2), rats were fed diets containing 1 or 2 g/kg of genistein, or an isoflavone-free diet for 16 days. Genistein at a dietary level of 2 g/kg reduced serum triacylglycerol concentrations in both experiments, and serum concentrations of cholesterol in Expt. 2. However, daidzein at 2 g/kg did not decrease serum lipid concentrations in Expt. 1. A DNA microarray analysis in Expt. 1 showed that genistein was stronger than daidzein in affecting gene expression in liver, targeting many genes involved in lipid and carbohydrate metabolism. Detailed analyses indicated that alterations in the expression of genes related to lipogenesis are primarily responsible for the serum lipid-lowering effect of genistein. This notion was supported by analyses of the activity of enzymes involved in lipogenesis in Expt. 2.

Two New Iridoid Glucosides from the Whole Plant of Patrinia scabiosifolia Link.

Project description:As a traditional Chinese medicine, Patrinia scabiosifolia Link has been used to treat various inflammatory-related diseases, and recent studies have shown that it possesses potent anti-inflammatory activity. Therefore, phytochemical investigation on whole plants of P. scabiosifolia were carried out, which led to the isolation of two new iridoid glucosides, patriniscabiosides A (1) and B (2), together with six known compounds (3-8). The structural elucidation of all compounds was performed by HRESIMS and extensive spectroscopic analyses including IR, 1D, 2D NMR, and electronic circular dichroism (ECD). All the isolated compounds were tested for their anti-inflammatory activity using the NF-κB-Dependent Reporter Gene Expression Assay, and compound 3 displayed anti-inflammatory activity through the inhibition of the NF-κB pathway, with an inhibitory rate of 73.44% at a concentration of 10 μM.
