Description
5-Fluorouridine (316-46-1) is an inhibitor of ribozyme self-cleavage in mammalian cells.1? Induces apoptosis in HCT-116 colorectal carcinoma cells causing diverse gene expression patterns suggesting that mechanisms besides global inhibition of RNA synthesis and processing contribute to 5-fluorouridine cytotoxicity.2 Cell permeable and active in vivo.
Chemical Properties
White Powder
Uses
5-Fluorouridine exhibits anticancer activity. It is often used in chemical and biochemical comparison studies with fluorouracil and thymine analogs. It is an active metabolite of Doxifluridine.
Uses
5-Fluoro Uridine is an active metabolite of Doxifluridine (D556750).
Definition
ChEBI: An organofluorine compound that is uridine bearing a fluoro substituent at position 5 on the uracil ring.
General Description
5-Fluorouridine (FUrd) is a fluoropyrimidine nucleoside analog and a cell-permeable modified RNA precursor.
Biochem/physiol Actions
5-Fluorouridine (FUrd) is cytotoxic towards cancer cells. FUrd is often used in chemical and biochemical comparison studies with fluorouracil and thymine analogs.
Purification Methods
5Fluorouridine is recrystallised from EtOH/Et2O and dried at 100o in a vacuum. UV: max 269nm (pH 7.2, H2O), 270nm (pH 14, H2O). [Liang et al. Mol Pharmacol 21 224 1982, Beilstein 24 III/IV 1231.]
