Description

Eleven groups of six ICR mice were dosed orally with 22.5 mg/kg 2,4-dinitrophenol. Groups were sacrificed at 0, 0.5, 1, 2, 4, 6, 9, 12, 24, 48, and 96 h post-treatment and plasma was collected for analysis of dinitrophenol, 2-amino-4-nitrophenol, and 4-amino-2-nitrophenol content. Analyses were performed by capillary gas spectrometry after liquid-liquid extraction of plasma specimens spiked with two internal standards. Quantification was based upon peak-area ratios of base peaks obtained from the three analytes and the trideuterated internal standards 2,4-dinitrophenol and 2-amino-4-nitrophenol. Plasma concentrations for each analyte versus thei subjected to pharmacokinetic analysis. Of the two monoamine metabolites, 2-amino-4-nitrophenol was present in the greater amount and had an elimination plasma while that of 4-amino-2-nitrophenol was 26 h.
