Plasma metabolites of quercetin and their antioxidant properties.
Quercetin is one of the most widely distributed flavonoids present in fruits and vegetables. The present experiments were performed on rats adapted for 3 wk to a semipurified diet supplemented with 0.2% quercetin. The major part of the circulating metabolites of quercetin (91.5%) are glucurono-sulfo conjugates of isorhamnetin (3'-O-methyl quercetin; 89.1 ± 2.1 μM) and of quercetin (14.7 ± 1.7 μ...
متن کاملElectrochemical and Antioxidant Properties of (+)-Catechin, Quercetin and Rutin
The electrochemical properties of three structurally different flavonoids ((+)-catechin, quercetin and rutin) on a glassy carbon electrode were studied at different pH by cyclic, differential pulse and square-wave voltammetry. It was determined that in all investigated compounds oxidation of catechol 3',4'-dihydroxy group on the B-ring (the first oxidation peak) occurs. This process is reversib...
متن کاملcloso-borane conjugated regulatory peptides retain high biological affinity: synthesis of closo-borane conjugated Tyr(3)-octreotate derivatives for BNCT.
Despite the improvements in cancer therapy during the past years, high-grade gliomas and many other types of cancer are still extremely resistant to current forms of therapy. Boron neutron capture therapy (BNCT) provides a promising way to destroy cancer cells without damaging healthy tissue. However, BNCT in practice is still limited due to the lack of boron-containing compounds that selective...
متن کاملAscorbate is an outstanding antioxidant in human blood plasma.
We have shown recently that the temporal order of antioxidant consumption in human blood plasma exposed to a constant flux of aqueous peroxyl radicals is ascorbate = protein thiols greater than bilirubin greater than urate greater than alpha-tocopherol and that detectable lipid peroxidation starts only after ascorbate has been consumed completely. In this paper, we show that it is indeed ascorb...
متن کاملAntioxidant and antifungal properties of benzimidazole derivatives.
Antioxidant and radical scavenging properties of a series of 2-[4-(substituted piperazin-/piperidin-1-ylcarbonyl)phenyl]-1H-benzimidazole derivatives were examined. Free radical scavenging properties of compounds 11-30 and 33 were evaluated for the stable free radical 2,2-diphenyl-1-picrylhydrazyl (DPPH) and superoxide anion radical. In addition the inhibitory effects on the NADPH-dependent lip...
