Abstract:
Genistein was defined to be an allosteric xanthine oxidase inhibitor in the concentrations 0.1-4.0 microM and xanthine oxidase activator with superoxide scavenging activity in the concentrations 5.0 microM and higher. But the most effective allosteric binding with the highest affinity was observed in the genistein concentrations 0.1-1.0 microM. Intraperitoneum injections of genistein (500 micrograms/kg) during three days with the interval 24 hours decrease xanthine oxidase activity in the liver, lung and brain of the Vistar rats.
