| Research Abstract |
In this study, we investigated the activity of drug-metabolizing enzymes such as UGT and SULT using soy isoflavone metabolism in vivo. The results of enzymatic study indicated that UGT1A9 mainly catalyzed 7-glucuronidation of genistein. The quantification of 16 isoflavone metabolites in human plasma revealed that daidzein-7-glucuronide-4'-sulfate and genistein-7-glucuronide-4'-sulfate were major metabolites. Further study about drug-metabolizing enzymes catalyzing the glucuronidation and sulfation of isoflavones is being performed.
