It is absorbed through the skin.

The disposition of 14(C)-labeled p-nitroaniline was studied in male rats following oral or iv admin. The clearance of 14(C) p-nitroaniline-derived radioactivity from various tissues was rapid and followed a 2-component decay curve. The whole-body half-life of p-nitroaniline was approximately 1 hr. Within 3 days, clearance of p-nitroaniline-derived radioactivity from the body was almost complete. 14(C) p-nitroaniline was rapidly cleared by metabolism to 9 metabolites which were excreted primarily in the urine and to a lesser extent in the feces. Most (56%) of the urinary radioactivity was in the form of sulfate conjugates of 2 metabolites of p-nitroaniline.

The percutaneous absorption of nitrobenzene, p-nitroaniline, 2,4-dinitrochlorobenzene, 2-nitro-p-phenylenediamine, and 4-amino-2-nitrophenol was studied in vivo and in vitro. The compounds were applied to shaved abdominal skins of Rhesus-monkeys at a concentration of 4 ug/sq cm. Five day urine samples were collected and analyzed for the compounds. Radiolabeled nitrobenzene, p-nitroaniline, 2-4-dinitrochlorobenzene, 2-nitro-p-phenylenediamine, or 4-amino-2-nitrophenol were applied to excised human skin at a dose of 4 ug/sq cm using a diffusion cell technique. Penetration of radioactivity through the skin was monitored for the next 24 hours. The compounds rapidly penetrated excised human skin, the greatest penetration occurring in the first 2 hours after exposure. The ability of the compounds to penetrate human skin ranked in decreasing order of permeability and corrected for evaporation was 4-amino-2-nitrophenol, nitrobenzene, p-nitroaniline, 2,4-dinitrochlorobenzene, and 2-nitro-p-phenylenediamine. The corresponding rank for penetration of monkey skin was 4-amino-2-nitrophenol, p-nitroaniline, 2,4-dinitrochlorobenzene, 2-nitro-p-phenylenediamine, and nitrobenzene.

5.2 Metabolism/Metabolites

Given orally or ip in doses of 20-40 mg/kg in rats, analysis of 24-hr urine samples showed that 4-nitroaniline was excreted partly unchanged & also as 4-phenylenediamine & 2-amino-5-nitrophenol...

The principal rat liver microsomal metabolite of 4-nitroaniline was isolated by high performance liquid chromatography and characterized as 2-amino-5-nitrophenol. Pretreatment of rats with phenobarbital and 3-methylcholanthrene increased the rate of conversion of 4-nitroaniline to 2-amino-5-nitrophenol by 2- and 4-fold, respectively.

PMID:6144483 Anderson MM et al; Drug Metab Dispos 12 (2): 179-85 (1984)


The metabolism of radiolabeled dinitrobenzene isomers was compared in hepatocytes and hepatic subcellular fractions isolated from male rats. Under aerobic conditions, reduction was the major metabolic pathway for m-dinitrobenzene and p-dinitrobenzene in hepatocytes with m-nitroaniline and p-nitroaniline accounting for 74.0 and 81.0% respectively, of the radioactivity present after a 30-minute incubation. The major metabolite of o-nitrobenzene in similar incubations was S-(2-nitrophenyl)glutathione which represented 48.1% of the total radioactivity. o-Nitroaniline accounted for 29.5% of the radioactivity.

14(C) p-nitroaniline was rapidly cleared by metabolism to 9 metabolites which were excreted primarily in the urine and to a lesser extent in the feces. Most (56%) of the urinary radioactivity was in the form of sulfate conjugates of 2 metabolites of p-nitroaniline.

5.3 Biological Half-Life

The whole-body half-life of p-nitroaniline was approximately 1 hr.

5.4 Mechanism of Action

... To assess further the role of the 4-substituent in methaemoglobinaemia, the toxicity of a series of 4-substituted aniline derivatives was also studied. Of the anilines studied, 4-nitroaniline caused the most methemoglobin (36.5 +/- 8.0%), while aniline caused the least (0.3 +/- 0.5%). Overall, there was a significant correlation (r2 = 0.83) between the hemotoxicity and the Hammett constant, sigma(p), suggesting that it is the electron-withdrawing properties of the substituent that influence the methemoglobin formation. ...

The relative mutagenic activities of aminoanilines have been attempted to be related to parameters reflecting potential for n-hydroxylation and stability of the arylnitrenium ions. Both chloro and the nitro groups deactivate the amine group to n-hydroxylation and the ring to epoxidation, & no active products from cytochrome p450 would be predicted. The activity of the nitro derivatives is presumed to be due to transformation of the nitro group itself to an active mutagenic species by other enzyme systems. /Aminoanilines/
