Abstract

No report has been addressed to the CYP isoforms catalyzing chlorpropamide, a structural analogue of tolbutamide. To evaluate enzyme(s) mediating formation of 2-hydroxycWorpropamide, a major metabolite and identified by LC/Mass and NMR, incubation studies using human liver microsomes and cDNA expressed CYP were performed on the presence or absence of selective inhibitors of each CYP isoform.
