Description

1-(2-DEOXY-2-FLUORO-β-D-ARABINOFURANOSYL)URACIL (FAU) is a thymidine analog. In several cancer cell lines, FAU was phosphorylated intracellularly to its monophosphate, 1-(2-deoxy-2-fluoro--Darabinofuranosyl) uracil monophosphate (FAUMP), by thymidine kinase and methylated in the 5-position by thymidylate synthase to form the product, 1-(2-deoxy-2-fluoro- -D-arabinofuranosyl) 5-methyluracil monophosphate (FMAUMP). FAU strongly inhibits the growth of tumor cells with high thymidylate synthase activity. FAU had been in phase I clinical trial for the treatment of advanced solid tumors.
