Effect of copper on blood serum xanthine dehydrogenase in rats given D-L-ethionine. 1985

O R Affonso, and A S Souza, and E Mitidieri

Hepatic lesions by D-L-ethionine in rats produce a significant increase in the blood serum xanthine dehydrogenase activity. Cupric acetate is a potent inhibitor (Ki = 3.42 X 10(-6) M) of the xanthine dehydrogenase activity. Ethionine protects against the inhibitory effect of cupric acetate by formation of a copper complex with behaviour different from that of free ethionine.
