By using the cytochrome P450 inhibitor malathion and amitrole with ALS and ACCase herbicides, respectively, we showed that malathion reverses chlorsulfuron resistance and amitrole reverses diclofop resistance in the R population examined.

By contrast, 50-87% of the oxidation of ethanol by these cells was inhibited by carbon monoxide, metyrapone and SKF-525A, all three of which are known to inhibit various species of microsomal cytochrome P-450.

Induction of the cytochrome P-450 enzymes by phenobarbital (PB) pretreatment doubled the yield of cyanide, while SKF-525A blocked this PB-induced increase.

Pretreatment with either SKF, a cytochrome P450 inhibitor, or L-ascorbic acid, an antioxidant, completely suppressed the increase in ROS levels and apoptosis, suggesting that the sustained ROS increases may cause the apoptosis.

Under these conditions, the peroxidatic activity of catalase measured in vitro and the ethanol-dependent decrease in catalase-H2O2 in perfused livers also returned to near basal levels; however, the oxidation of ethanol by cytochrome P-450 was inhibited completely.

These parameters in neurons were relatively unaffected when the cells were incubated with ethanol in the presence of inhibitors of alcohol-oxidizing enzymes, but in thymocytes, the presence of diallyl sulfide (an inhibitor of alcohol-inducible cytochrome P450, CYP2E1) or 4-methylpyrazole (an inhibitor of CYP2E1 and alcohol dehydrogenase) caused decreases in ROS production from ethanol.

Lucigenin-dependent chemiluminescence cannot be used for measuring the modulating action of agents on reactive oxygen species production in the microsomes, but it may be used for luminometrical studies of enzyme complex NAD (P) H-reductases/cytochrome P450 in model systems.

Endogenous hydrogen peroxide (H2O2) release from aortic endothelial cells was studied in the presence of antioxidant enzyme inhibitors, mitochondrial inhibitors, a microsomal cytochrome P-450 inhibitor, and after oxidative stress induced with H2O2 or menadione.

ROS also reduced viability, but this was observed only after both cytochrome P450 stimulation and catalase inhibition.
