This investigation was designed to determine whether biliary excretion of bromobenzene-glutathione conjugate can be used as an index of in vivo activation of bromobenzene. To test this hypothesis, the effect of chemicals known to alter the toxicity and biotransformation of bromobenzene (ie, cytochrome p450 inducers and inhibitors) on the biliary excretion of bromobenzene-glutathione was studied in rats. Bromobenzene-glutathione was the major bromobenzene metabolite in bile. A linear relationship was observed between the dosage of bromobenzene administered and bromobenzene-glutathione excreted into bile, up to a dosage of 250 umol/kg of bromobenzene. Of the inducers tested, Phenobarbital, which is known to increase the toxicity of bromobenzene, dramatically increased 1700 m1 the rate of biliary excretion of bromobenzene-glutathione over that in control animals. In contrast, 3-methylcholanthrene, which is known to decrease the hepatotoxicity of bromobenzene, decreased the biliary excretion of bromobenzene-glutathione (56%). Inhibitors of p450, such as SKF 525-A and piperonyl butoxide which are known to decrease the activation and hepatotoxicity of bromobenzene, also decreased the biliary excretion of bromobenzene-glutathione. These findings are in agreement with the hypothesis that the biliary excretion of bromobenzene-glutathione reflects the formation of the reactive bromobenzene metabolite in liver and the rate of biliary excretion can be used to determine factors that are important in determining the toxicity of bromobenzene.

BROMOBENZENE IS METABOLIZED VIA THE HEPATIC MIXED-FUNCTION OXIDASE SYSTEM TO REACTIVE INTERMEDIATES 2,3- AND 3,4-BROMOBENZENE EPOXIDES. THESE METABOLITES PRESUMABLY BIND TO TISSUE MACROMOLECULES. THE SPECIFIC SITES OF MACROMOLECULAR PROTEINS WERE INVESTIGATED. THE 3,4-EPOXIDE IS MORE REACTIVE, BINDING COVALENTLY TO MICROSOMAL PROTEIN AT THE SITE OF ITS SYNTHESIS, WHEREAS BROMOBENZENE 2,3-EPOXIDE IS MORE STABLE, LEAVING THE MICROSOMAL PROTEIN COMPARTMENT AND BINDING COVALENTLY TO SOL PROTEIN, IE THE HEMOGLOBIN BETA CHAIN.

Bromobenzene is converted to either the 3,4-oxide derivative catalyzed primarily by phenobarbital-induced cytochrome isozymes (e.g., CYP 450 1A2, 2A6, 2B6, and 3A4), or the 2,3-oxide derivative catalyzed primarily by 3-methylcholanthrene and -naphthoflavone-induced CYP isozymes (e.g., CYP 450 1A1, 1A2, and 1B1). This is followed by urinary excretion as premercapturic and mercapturic acids.
FOLLOWING BROMOBENZENE (1.0 MMOL) ADMIN TO RAT HEPATOCYTES, LIPID PEROXIDATION OCCURRED ONLY AT A LATER STAGE, COMPARED TO TREATMENT WITH CCL4, AND ONLY AFTER CELL DEATH. APPARENTLY LIPID PEROXIDATION DURING BROMOBENZENE TOXICITY WAS MERELY A CONSEQUENCE OF GSH DEPLETION AND CELL DEATH. APPARENTLY, ARYLATION OF CRITICAL CELLULAR NUCLEOPHILES IS MORE IMPORTANT THAN LIPID PEROXIDATION IN BROMOBENZENE HEPATOTOXICITY.

FRESHLY ISOLATED HEPATOCYTES FROM PHENOBARBITAL-TREATED RATS WERE INCUBATED IN THE PRESENCE OR ABSENCE OF EXTRACELLULAR CALCIUM WITH BROMOBENZENE. IN THE ABSENCE OF CALCIUM IT WAS FAR MORE TOXIC TO THE CELLS THAN IN ITS PRESENCE. THIS RESULT IS INCONSISTENT WITH THE HYPOTHESIS THAT AN INFLUX OF EXTRACELLULAR CALCIUM IS REQUIRED AS THE FINAL STEP IN TOXIC LIVER CELL INJURY.

A NOVEL METHOD IS DESCRIBED FOR MEASURING THE COVALENT BINDING OF BROMOBENZENE TO MACROMOLECULES IN RAT HEPATIC MICROSOMES OF HEPATOCYTES. COVALENT BINDING IN HEPATOCYTES SUGGESTS THAT THE BINDING OCCURS FIRST WITH MACROMOLECULES IN 20000-40000 DALTON RANGE.
