1-(2'-Deoxy-2'-fluoro-α-L-arabinofuranosyl)-thymine (commonly abbreviated as L-FMAU) is a nucleoside analog. It contains an α-L-arabinofuranose sugar instead of the natural β-D-deoxyribose found in DNA. A fluorine (F) substitution at the 2'-position enhances stability and resistance to enzymatic degradation. The thymine nucleobase allows it to mimic natural thymidine, potentially incorporating into DNA synthesis pathways. It can be research for its potential antiviral activity.
