Electrochemical simulation of phase I metabolism for 21 drugs using four different working electrodes in an automated...

Electrochemical conversion of xenobiotics has been shown to mimic human phase I metabolism for a few compounds.

Twenty-one compounds were analyzed with a semiautomated electrochemical setup and mass spectrometry detection.

The system was able to mimic some metabolic pathways, such as oxygen gain, dealkylation and deiodination, but many of the expected and known metabolites were not produced.

Electrochemical conversion is a useful approach for the preparative synthesis of some types of metabolites, but as a screening method for unknown phase I metabolites, the method is, in our opinion, inferior to incubation with human liver microsomes and in vivo experiments with laboratory animals, for example.
