Description: Doxifluridine, also known as 5'-Deoxy-5-fluorouridine, is a fluoropyrimidine derivative and oral prodrug of the antineoplastic agent 5-fluorouracil (5-FU) with antitumor activity. Doxifluridine, designed to circumvent the rapid degradation of 5-FU by dihydropyrimidine dehydrogenase in the gut wall, is converted into 5-FU in the presence of pyrimidine nucleoside phosphorylase.

Biological target: Doxifluridine (Ro 21-9738; 5'-DFUR) is a thymidine phosphorylase activator for PC9-DPE2 cells with IC50 of 0.62 μM.
In vitro activity: The doxifluridine-conjugated 8-methyladenosine-substituted 2-5A analog was significantly more effective as an activator of RNase L than the parent 5'-monophophorylated 2-5A tetramer and showed a tumor suppressive effect against human cervical cancer cells. Reference: Bioorg Med Chem. 2016 Aug 15;24(16):3870-4. https://pubmed.ncbi.nlm.nih.gov/27364610/
In vivo activity: The antitumor and anti-angiogenic effects of metronomic doxifluridine (delivered via oral gavage) in combination with TNP-470 were evaluated in vivo in mice. Metronomic doxifluridine alone significantly suppressed tumor growth compared with the untreated (control) group, while metronomic doxifluridine in combination with TNP-470 significantly inhibited tumor growth compared with each treatment alone.
