Cigarette smoke-induced airway inflammation is one of the most important features of chronic airway diseases. Studies suggest that chrysin possesses strong anti-inflammatory properties and this study aimed to investigate the effect of chrysin on cigarette smoke-induced airway inflammation in mice. Mice with exposure to cigarette smoke were intraperitonealy injected with chrysin (10, 20 mg/kg·d)...

BACKGROUND/AIMS To study the therapeutic effect of chrysin, a flavonoid with strong antioxidant and anti-inflammatory activities, on adenine-induced chronic kidney diseases (CKD) in rats. METHODS Chrysin, in three graded oral doses (10, 50 and 250 mg/kg), was given for 10 consecutive days to rats after the induction of CKD by feeding them adenine (0.25%(w/w) for 35 days). Several plasma and u...

Chrysin (5,7-dihydroxyflavone) is a natural and biologically active compound extracted from honey, plants and propolis. It possesses anti-inflammatory activity, anti-oxidant properties and promotes cell death by perturbing cell cycle progression. In this study, our attention focused on the possible role that chrysin may have as a potential anti-cancer agent, and we tested its biological activit...

Background: Clinically Gentamicin (GM) is commonly used aminoglycoside antibiotic for the treatment of life-threatening Gram-negative bacterial infections, but the nephrotoxic potential of drug limit its clinical interest. Chrysin a plant flavonoid possess potent antioxidant and anti-inflammatory activity. Objective: To investigate the potential of chrysin against GM-induced nephrotoxicity. Mat...

PURPOSE Selenite-induced cataract is associated with oxidative stress, loss of calcium homeostasis, activation of calpain enzymes, and apoptotic cell death in the lens. An evaluation of naturally occurring antioxidants that also restrict calcium influx into the lens and calpain activation and thus prevent lenticular cell death may lead to the development of safe and effective anticataractogenic...

PURPOSE The activities of breast cancer resistance protein (Bcrp/ABCG2) as well as P-glycoprotein (P-gp) and drug-metabolizing enzymes can be inhibited by several flavonoids or drugs in rats. However, the species, gender and regional differences of effects of flavonoids on Bcrp/ABCG2 in rats and mice remain unclear, although Bcrp, like P-gp, is also important in controlling drug absorption and ...

Chrysin (5, 7- dihydroxyflavone) is a flavonoid with several pharmacological properties that include antioxidant, anti-inflammatory and antiapoptotic activities. in this work, we investigated some effects of three graded oral doses of chrysin (10, 50 and 250 mg/kg) on kidney structure and function in rats with experimental chronic renal disease (CKD) induced by adenine (0.25% w/w in feed for 35...

This study aims to elucidate the effects of chrysin on human ER-negative breast cancer cell line, MDA-MB-231. The study demonstrated that treatment of MDA-MB-231 cells with 20 microM chysin for 48 h significantly inhibited the growth of MDA-MB-231 cells and induced cytoplasmic lipid accumulation in the cells, but that the observed of cell death was not caused by apoptosis. The expression of PPA...

The known flavone, chrysin (1) and the known flavone glycoside, chrysin-7-O-(β-D-glucopyranoside) (2) together with vomifoliol, loliode and cinnamic acid have been isolated for the first time from the leaves and flowers of Calycotome spinosa (L.). Lamk, theirs structures were established on the basis of spectroscopic technical; H-, C-NMR, 2D NMR and MS (I.E).

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...
