[In vitro study of regulation of rat liver xanthine oxidase activity by antioxidant reducing agents]
1I.I. Mechnikov Odessa State University.
Abstract:
It was learned the regulation of xanthine oxidase activity from rat liver in the partly purified prepared by ascorbic acid, glutathione-SH, dithiothreitol, cysteine++ and hydrocortisone++. It was shown that ascorbic acid glutathione-SH, dithiothreitol, and cysteine++ can be activators and uncompetitor inhibitors of xanthine oxidase in dependence from concentration. As far as hydrocortisone is concerned, it is a powerful uncompetitor inhibitor of xanthine oxidase, that is bind with it. It was considered the mechanism of activation and inhibition of xanthine oxidase by these reductors-antioxidants.
