Toxicology and applied pharmacology, 111(1), 1-12 (1991-10-01)
Phenacetin is well known to cause hemolytic anemia and methemoglobinemia in humans. Early mechanistic studies clearly established a causal role for active/reactive drug metabolites in the process but did not unequivocally identify these metabolite(s) or resolve the question of whether
E C McCoy et al.
Mutation research, 173(4), 245-250 (1986-04-01)
Two mutagenic metabolites of phenacetin, p-nitrosophenetol and N-hydroxy-p-phenetidine, were tested in S. typhimurium strains TA100, its nitroreductase-deficient derivative TA100NR, and O-acetylase-deficient strains TA100 Tn5-1,8-DNP1011 and -DNP1012 in the presence or absence of an exogenous metabolic activation system. The results indicate

The toxicity of some metabolic products pertinent to 4-ethoxyaniline in isolated hepatocytes were investigated. The compounds investigated were 4-ethoxynitrosobenzene (1), 4-ethoxy-4'-nitrosodiphenylamine (2), 3,6-bis(4-ethoxy-phenylimino)-4-ethoxy-1,4-cyclohexadienylamine (3), 4-(4-ethoxyphenylimino)-2,3-dimethyl-2,5-cyclohexadiene-1-one (4) and 4-(4-ethoxyphenylimino)-2,6-dimethyl-2,5-cyclohexadiene-1-one (5). Of these, 1, 2 and 3 are oxidation products of 4-ethoxyaniline.

Horseradish peroxidase-catalyzed oxidation of p-phenetidine in the presence of either glutathione (GSH), cysteine, or N-acetylcysteine led to the production of the appropriate thioyl radical which could be observed using EPR spectroscopy in conjunction with the spin trap 5,5-dimethyl-1-pyrroline-N-oxide. This confirms
