title: [Demonstration of the O-demethylation reaction catalyzed by a peroxidase: application to 9-methoxyellipticine].
abstract: 9-methoxy ellipticine, an antitumor compound, is O-demethylated in presence of the system peroxidase-H2O2; this reaction yields the corresponding electrophilic quinone-imine and methanol. This O-demethylation reaction is reported for the first time and might be possibly extended to some other antitumor drugs.
