Doxifluridine (5'-deoxy-5-fluorouridine) is a second generation nucleoside analog prodrug developed by Roche and used as a cytostatic agent in chemotherapy in several Asian countries including China and South Korea.[1] Doxifluridine is not FDA-approved for use in the USA. It is currently being evaluated in several clinical trials as a stand-alone or combination therapy treatment.
Biology
5-Fluorouracil (5-FU), the nucleobase of doxifluridine, is currently an FDA-approved antimetabolite.[2] 5-FU is normally administered intravenously to prevent its degradation by dihydropyrimidine dehydrogenase in the gut wall. Doxifluridine is a fluoropyrimidine derivative of 5-FU, thus a second-generation nucleoside prodrug. Doxifluridine was designed to improve oral bioavailability in order to avoid dihydropyrimidine dehydrogenase degradation in the digestive system.[3]
Within a cell, pyrimidine nucleoside phosphorylase or thymidine phosphorylase can metabolize doxifluridine into 5-FU.[4][5] It is also a metabolite of capecitabine.[4] High levels of pyrimidine-nucleoside phosphorylase and thymidine phosphorylase are expressed in esophageal, breast, cervical, pancreatic, and hepatic cancers.[6][7] Liberation of 5-FU is the active metabolite and leads to inhibition of DNA synthesis and cell death.
Side effects
High thymidine phosphorylase expression is also found in the human intestinal tract, resulting in dose-limiting toxicity (diarrhea) in some individuals.[8]
The most frequent adverse effects for doxifluridine were neurotoxicity and mucositis.[citation needed]
