In addition to the well known effect of phenylhydrazine on red blood cells (methaemoglobin and Heinz body formation, autologous IgG binding, lipid peroxidation, etc.) an increased glucose utilization was observed. Measurement of 14CO2 formation from [1-14C]-glucose showed a maximum value at 2mM phenylhydrazine followed by a progressive inhibition on increasing the drug concentration to 16 mM. Concomitantly we found a reduction in the reduced glutathione concentration but not a corresponding increase in the level of oxidized glutathione. Phenylhydrazine also causes ATP depletion. The ATP is in part dephosphorylated to ADP and AMP and in part converted to inosine monophosphate and hypoxanthine. Measurement of the cell content of reduced and oxidized pyridine nucleotides was also performed and showed a progressive increase in the reduced forms of these coenzymes. Thus phenylhydrazine promotes cellular ATP depletion followed by adenine nucleotide catabolism that is not efficiently counteracted by an increase in glucose utilization. The relevance of these data to the mechanism of phenylhydrazine-induced anemia is discussed.
