AB  - Quinhydrone (QH) is a redox active charge transfer complex commonly used as a redox standard. Information on quinhydrone generation in plants is scarce and its physiological role is still unclear. Recently we have showed that excess zinc may induce oxidative stress through QH accumulation in the cell wall and stabilization of phenoxyl radicals [1]. The aim of our research was to investigate the antifungal activity of quinhydrone against yeast Saccharomyces cerevisiae (112, Hefebank Weihenstephan). Saccharomyces cerevisiae was grown on the Sabouraud maltose broth (HiMedia, Mumbai, India) in the presence of different concentrations of QH ranging from 75 mu M to 500 mu M. Concentrations of QH greater than 300 mu M had complete inhibitory effect on yeast growth, while lower concentrations (up to 200 mu M) did not affect the growth. QH had a significant impact on antioxidative defense enzymatic systems, indicated by the changes in the activity in catalase (CAT) and superoxide dismutase (SOD). CAT activities increased by 43% (150 mu M QH) and SOD activities by 122% and 60% at 150 mu M and 220 mu M QH respectively. However, abrupt inhibition of both enzymes was observed at concentrations higher than 220 mu M QH (>= 70%), to be almost completely diminished at 280 mu M QH. High molecular weight genomic DNA without any laddering or smearing was detected in both control and QH treated yeast cells, indicating the absence of apoptosis.

AB  - Using electron paramagnetic resonance (EPR) spectroscopy, antioxidant properties of chestnut extracts have been investigated as a source of phenolic compounds. In addition to their high antioxidant activities against hydroxyl and organic free (DPPH) radicals, phenolics showed to be potent protectors of membranes from lipid peroxidation To the best Of Our knowledge, the ability of an antioxidant to overcome body's refractory response towards antioxidant supplementation has been examined for the first time. The water soluble extracts obtained from leaves, catkins, and outer brown peel of Castanea sativa Mill. showed high antioxidant activity in scavenging OH and DPPH radical All extracts, except for sweet chestnut catkins, showed the ability to protect liposomes from peroxidation Phenolic compounds, as active antioxidants, have the ability to enter and protect cell membranes from lipid peroxidation, thus overcoming the body's refractory response to the antioxidant supplements In the diet. It is shown that phenolics are easily accessible natural antioxidants that can be Used as food supplements or for the treatment of pathophysiological conditions related to oxidative stress.
