Methoxy-resorufin ether as an electrochemically active biological probe for cytochrome P450 O-demethylation.

This paper describes the utilisation of methoxy-resorufin ether as an electrochemical probe for studying cytochrome P450 CYP6G1. Methoxy-resorufin ether is well established as a versatile substrate for cytochrome P450, as its demethylated product, resorufin, is a fluorophore. We show that in addition to these established properties, methoxy-resorufin ether also exhibits reversible two electron transfer on glassy carbon and edge plane graphite electrodes.
