Metabolic reduction of acetohexamide by rabbit tissue

The in vitro metabolic reduction of acetohexamide was studied using rabbit tissue preparations. Acetohexamide is mainly reduced in the cytosols of rabbit liver and kidney, and its reduction is catalyzed by ketone reductases.
Determination of absolute configuration of a metabolite (-)- hydroxyhexamide from acetohexamide, syntheses of (-)- and (+)- hydroxyhexamides and (-)- and (+)-acetoxyhexamides

Enantioselective acetylation of (±)-4-(1- hydroxyethyl)benzenesulfonamide 6 with 'Acylase I' (No. A 2156) from Aspergillus melleus in the presence of vinyl acetate gave (R)-4-(1- acetoxyethyl)benzenesulfonamide 7 (98% ee) and (S)-6 (98% ee). Both (S)-6 and (R)-7 were individually converted to the (S)-hydroxyhexamide 2 (>99% ee) and (R)-hydroxyhexamide 2 (>99% ee), respectively. The absolute configuration of a metabolite (-)-hydroxyhexamide 2 from acetohexamide 1 was found to be S based on unequivocal chemical methods including X-ray analysis.

, p. 221 - 227 (2007/10/03)
In this study, we compared the enzymatic reduction of 10 drugs with a ketone group by homogeneous carbonyl reductase, aldehyde reductase and three dihydrodiol dehydrogenases of human liver cytosol. At least one and in some cases all of the three dihydrodi
