Nucleoside Derivatives - Fluoro-modified nucleosides; 2’-Modified nucleosides; 5-Modified pyrimidine nucleosides; Metabolite of FMAU

1-(2’-Deoxy-2’-fluoro-arabinofuranosyl)-5-hydroxymethyluracil (also abbreviated as FMAU-OH) is a modified nucleoside analog. It consists of a fluorinated sugar moiety (2’-deoxy-2’-fluoro-arabinofuranose) attached to a uracil base with a hydroxymethyl (-CH₂OH) group at the 5-position. The 2’-fluoro substitution and arabinose sugar configuration can enhance its stability and affect its incorporation into DNA or RNA. It has the potential to be used as an inhibitor of viral polymerases and can be used in research.
