Drug Metab Dispos. 1996 Jan;24(1):81-90.


In addition, CH-induced lipid peroxidation catalyzed by control-microsomes and pyrazole-microsomes was reduced significantly by 2,4-dichloro-6-phenylphenoxyethylamine, a general cytochrome P450 inhibitor.

Diallyl sulfide, a selective, mechanism-based inhibitor of cytochrome P-450 2E1, inhibited the metabolism of HCFC-141b, as indicated by a decreased uptake of HCFC-141b and by a lowered urinary excretion of 2,2-dichloro-2-fluoroethanol in diallyl-sulfide-treated rats.

It was previously shown that TCE metabolites in plants are similar to ones that result from cytochrome P450-mediated oxidation in mammals: trichloroethanol, trichloroacetate and dichloroacetate.

Cytochrome P-450 appears to be involved in TCE degradation, as evidenced by marked inhibition of degradation of TCE in the presence of 1-aminobenzotriazole, a known inhibitor of cytochrome P-450.

The effect of low doses of diethyldithiocarbamate (DEDC) on hepatic cytochrome P450-dependent enzyme activity and 1,3-dichloro-2-propanol (DCP) hepatotoxicity in the rat have been investigated.

Additionally, transformation of trans-chlordane and production of hydroxylated metabolites were efficiently inhibited by the addition of cytochrome P450 inhibitors, piperonyl butoxide and 1-aminobenzotriazole, demonstrating that fungal cytochrome P450 enzymes are involved in some steps of trans-chlordane metabolism, particularly in the hydroxylation process.

The test was applied here in its standard version with normal bioactivation and in a variant with increased cytochrome P450-dependent bioactivation capacity.
