Metabolism of 3-acetylcoumarin in rat 9000xg supernatant fraction (S-9)and baker's yeast.
In the incubation of 3-acetylcoumarin in rat liver supernatant fraction (S-9), four metabolites were isolated, and two of which were inseparable diastereomeric mixture as a major product. However, when 3-acetylcoumarin was fermented with baker's yeast (Saccharomyces cerevisiae), only two compounds were obtained as the same as the above mixture. The structures of those metabolites were confirmed by NMR and Mass spectra. However, the above metabolites in rat 9000xg supernatant fraction were not induced by phenobarbital, nor inhibited with SKF-525A at all.
