Application of micellar electrokinetic capillary chromatography for evaluation of inhibitory effects on cytochrome P450 reaction.

The major aim of this work is to demonstrate the applicability of micellar electrokinetic capillary chromatography with SDS based pseudostationary phase for the screening of cytochrome P450 inhibitors. In contrast with the other capillary electrophoresis modes the cytochrome P450 reaction mixture thus could be used for the analysis without any pre-treatment. Cytochrome P450 2C9, one of the most important isoforms in human liver, was chosen as a model example for this study in combination with diclofenac as a probe substrate.
