Chrysin (CHR), a flavone found in multiple vegetables, fruits and mushrooms has been explored so far as neurotropic, anti-inflammatory anti-cancer biomolecule. Despite the stated therapeutic potential, low solubility bioavailability limit its benefit. To circumvent these drawbacks, development of chrysin liposomes (CLPs) is reported present investigation. The CLPs were developed by electrostati...

Ten propolis samples from Bulgaria, Italy and Switzerland were analyzed by GC-MS. As expected, most samples displayed the typical chemical pattern of "poplar" propolis: they contained pinocembrin, pinobanksin and its 3-O-acetate, chrysin, galangin, prenyl esters of caffeic and ferulic acids. Two samples differed significantly: one from the Graubünden Alpine region, Switzerland, rich in phenolic...

The mutagenicity of ten flavonoids was assayed by the Ames test, in Salmonella typhimurium strains TA98, TA100 and TA102, with the aim of establishing hydroxylation pattern-mutagenicity relationship profiles. The compounds assessed were: quercetin, kaempferol, luteolin, fisetin, chrysin, galangin, flavone, 3-hydroxyflavone, 5-hydroxyflavone and 7-hydroxyflavone. In the Ames assay, quer...

Active transport of glucuronide out of cells is a critical process in elimination of drugs via the glucuronidation pathway. Here, HeLa cells were stably transfected with UGT1A1 and the contributions of BCRP and MRP family transporters to the cellular efflux of chrysin glucuronide (CG) were determined. The cDNA of UGT1A1 was introduced into HeLa cells using the lentiviral transfection method. Th...
