background and aims: flavonoids as polyphenolic naturally occurring compounds have antioxidant activity. there is increasing evidence suggests that flavonoids may affect the activity of enzymes. paraoxonase 1 is calcium - dependent enzyme that is present in high density lipoproteins. this enzyme has an important role in the prevention of low density lipoprotein oxidation. we investigated the ef...
Flavonoids are pigmentary compounds existing widely in plants. We have reported that quercetin (3, 3', 4', 5, 7-pentahydroxylflavone), one of the typical flavonoids, strongly promotes melanogenesis by melanocytes. Meanwhile, there are 8000 or more flavonoids having a chemical structure different from each other in the natural world. Their distinctive chemical properties suggest that they may be...
Dietary flavonoids show beneficial effects in the prevention of chronic diseases. However, flavonoid bioavailability is poor, probably due to their interaction with serum albumins. In the current work, the binding interactions of eight related flavonoids, sharing a similar core structure, with bovine serum albumin (BSA) were investigated by fluorescence spectroscopy. The binding affinities of t...
