Measurement of cytochrome P450 2E1 activity in rat tracheobronchial airways using high-performance liquid chromatography with electrochemical detection.


Cytochrome P450 2E1 catalyzes the metabolic activation of nitrosamines and haloalkenes to carcinogenic and cytotoxic derivatives; however, the regulation of this P450 isozyme is not well understood. Hydroxylation of p-nitrophenol to p-nitrocatechol has been used as a marker of CYP2E1 activity, but currently available methodologies are not sufficiently… (More)
