Inhibitory effects of pyrimidine, barbituric acid and pyridine derivatives on 5-fluorouracil degradation in rat liver extracts.


The inhibitory effects of about 30 compounds, mainly pyrimidine and pyridine derivatives, on 5-fluorouracil degradation catalyzed by dihydrouracil dehydrogenase (DHU dehydrogenase) were investigated. The inhibitory activities of 5-substituted uracil derivatives decreased time-dependently during preincubation with liver extracts, indicating that these… (More)
