Incubations of 3'-hydroxyacetanilide (3HAA) with hepatic microsomal preparations from phenobarbital-pretreated mice led to the formation of three products of aromatic hydroxylation, viz. 2',5'-, 3',4'-, and 2',3'-dihydroxyacetanilide, which were identified by GC/MS techniques and quantified by GLC analysis. NADPH-dependent covalent binding
A model system for the detection of reactive metabolites, using glutathione depletion after microsomal activation, has been described previously. We developed a battery of complementary test systems using rat liver microsomes for metabolism and aqueous glutathione solutions, human erythrocytes or

Acetaminophen (250 mg/kg) administered intraperitoneally to fasted, phenobarbital-induced mice produced hepatotoxicity. No hepatotoxicity was observed after the administration of the regioisomer 3'-hydroxyacetanilide (600 mg/kg). Similar levels of covalent binding to liver homogenates occurred in mice receiving either acetaminophen or 3'-hydroxyacetanilide
Identification of hepatic protein targets of the reactive metabolites of the non-hepatotoxic regioisomer of acetaminophen, 3'-hydroxyacetanilide, in the mouse in vivo using two-dimensional gel electrophoresis and mass spectrometry.

Acetaminophen (AAP), a widely used analgesic drug, can damage various organs when taken in large doses. In this study, we investigate whether AAP causes cell damage by altering the early signaling pathways associated with cell death and survival. AAP caused
