The metabolism of ftorafur in the beagle dog and rhesus monkey. 1977

R I Freudenthal, and D C Emmerling

1. Ftorafur, a fluorinated pyrimidine nucleoside antimetabolite, is metabolized by the beagle dog and rhesus monkey to 5-fluorouracil, which is subsequently biotransformed to the corresponding nucleosides, to alpha-fluoro-beta-ureidopropionic acid, to urea and to CO2. 2. In the dog, urea was the primary urinary metabolite while in the monkey, alpha-fluoro-beta-ureidopropionic acid predominated. 3. The dog and monkey excrete about 35 percent of the recovered dose as CO2. 4. The possibility that ftorafur is a relatively inactive transport form of 5-fluorouracil is discussed.

D001711	Biotransformation	The chemical alteration of an exogenous substance by or in a biological system. The alteration may inactivate the compound or it may result in the production of an active metabolite of an inactive parent compound. The alterations may be divided into METABOLIC DETOXICATION, PHASE I and METABOLIC DETOXICATION, PHASE II.
