description

Butazolidin (Phenylbutazone) inhibits the oxidative decarboxylation of pyruvate and α-ketoglutarate in a final concentration of 10 mg-% (3,24 · 10−4 m). Data are presented suggesting that the β-ketothiolase is inhibited. The following enzymes or enzyme systems are not inhibited: The enzymes of the respiratory chain, the enzymes of the citric acid cycle with exception of α-ketoglutaric oxidase, the glycolysis of hexosediphosphate (slight inhibition), acetate thiokinase, sulfanilamid transacetylase, pyruvic decarboxylase from yeast, arginase, xanthine oxidase, and D-amino acid oxidase.
