title: Use of the glucose oxidase/peroxidase method for glucose assay leads to overestimation of the inhibition of gluconeogenesis by aminopyrine.
abstract: 4-Aminoantipyrine strongly inhibits glucose determination by the glucose oxidase/peroxidase/dianisidine assay but does not interfere in the assay using glucose-6-phosphate dehydrogenase, hexokinase and ATP. As a result, the inhibition of gluconeogenesis by aminopyrine reported to be 50-90% (Bánhegyi, G., Mandl, J., Antoni, F. and Garzó, T. (1987) Biochim. Biophys. Acta 927, 406-416) is strongly overestimated and amounts to only 10-30%.
