Sharaf, A. A., M. T. Khayyal, A. Kheir-el-Din, A. A. Sharaf, and F. Kassem, "Biochemical effects of niridazole. I. In vitro and in vivo effect of niridazole on the rate of gluconeogenesis and oxidation of pyruvate and some Krebs cycle intermediates in mice.", Egyptian journal of bilharziasis, vol. 5, issue 1-2, pp. 49-57, 1978. Abstract

The effects of the antischistosomal drug, niridazole, on the rate of gluconeogenesis in kidney cortex slices and on the rate of oxidation of pyruvate and some Krebs cycle intermediates in liver homogenate of non infected mice were determined. In vitro, niridazole was found to inhibit the succinate and pyruvate oxidation at the high concentration tested (10(-3)M). The rate of gluconeogenesis from alpha-ketoglutarate was unaffected. In vivo, niridazole showed a stimulatory effect on the rate of gluconeogenesis from alpha-ketoglutarate and on the rate of oxidation of pyruvate at a dosage level of 100 mg/kg for 5 days. The observed changes were discussed and the differences observed between the in vivo and in vitro work were assumed to be due to exposure of the tissues to the unmetabolized drug in vitro and to the drug and its metabolites in vivo.

Abstract

The effects of the antischistosomal drug, niridazole, on the rate of gluconeogenesis in kidney cortex slices and on the rate of oxidation of pyruvate and some Krebs cycle intermediates in liver homogenates of infected mice were described. The effect of schistosoma mansoni infection on the previously mentioned parameters was also described. The infection per se did not affect the rate of gluconeogenesis from pyruvate, succinate and alpha-ketoglutarate when used as gluconeogenic precursors. In case of the rates of oxidation of pyruvate, succinate alpha-ketoglutarate and citrate, the infection decreased them significantly. In vitro, niridazole did not increase the inhibition of the rate of oxidation of different substances studied caused by the infection per se. The rate of gluconeogenesis from alpha-ketoglutarate was also unaffected. In vivo, niridazole did not affect the oxidoreductases more than did the infection per se. In fact in many cases, the drug tended to normalize the inhibitory effect of the infection on some of the enzyme systems, particularly in the case of the citrate succinate and pyruvate. On administration of 100 mg/kg of niridazole for 5 days (i.e. low dosage only) the rate of gluconeogenesis from pyruvate and alpha-ketoglutarate was stimulated. Such effects seem to be related to the presence of metabolites rather than to the parent drug.
