2,6-Dimethylphenol: a new metabolite of mexiletine.
A new metabolite, 2,6-dimethylphenol obtained by O-dealkylation of mexiletine by rabbit liver was identified. A g.c.-f.i.d. method was developed for its analysis in hepatic homogenates and some of the characteristics of the metabolic reaction were studied. Formation of 2,6-dimethylphenol is microsomal and is optimal under aerobic conditions. Both carbon monoxide and n-octylamine significantly depress this O-dealkylation reaction.
