[The effect of alloxan on activity of various enzymes of phosphorus metabolism in vitro]. / Vliianie alloksana in vitro na aktivnost' nekotorykh fermentov fosfornogo obmena.

Effect of alloxan on activity of acetylphosphatase, alkaline and acid phosphatases, phenylpyrophosphatase was studied in vitro. Alloxan at concentrations 100 microM-10 mM inhibited acid phosphatase and especially alkaline phosphatase. Reducing agents (pyrocatechol, hydroquinone, ascorbic acid), which are easily converted into corresponding oxidized forms, at concentrations 100 microM-1.0 mM activated alkaline phosphatase in rat kidney and small intestine.
