5-Fluoro-6-iodouridine is a nucleoside that is used as the starting material for synthesizing fluorinated pyrimidine derivatives, which are used in cancer treatment. 5-Fluoro-6-iodouridine is an activator of ribonucleotide reductase and can be used to inhibit the growth of tumor cells. 5-Fluoro-6-iodouridine has been shown to inhibit the proliferation of human leukemia cells in culture, with cytotoxicity that was comparable to that of 5-fluorouracil.
