IUPAC name: [(2R,3S,4S,5R)-5-(6-amino-2-fluoropurin-9-yl)-3,4-dihydroxyoxolan-2-yl]methyl dihydrogen phosphate
ChEBI definition: A purine arabinonucleoside monophosphate having 2-fluoroadenine as the nucleobase. A prodrug, it is rapidly dephosphorylated to 2-fluoro-ara-A and then phosphorylated intracellularly by deoxycytidine kinase to the active triphosphate, 2-fluoro-ara-ATP. Once incorporated into DNA, 2-fluoro-ara-ATP functions as a DNA chain terminator. It is used for the treatment of adult patients with B-cell chronic lymphocytic leukemia (CLL) who have not responded to, or whose disease has progressed during, treatment with at least one standard alkylating-agent containing regimenas.
Pharmacological roles (ChEBI): antineoplastic agent, immunosuppressive agent, antiviral agent, prodrug, DNA synthesis inhibitor.
Other ChEBI roles (chemical / environmental): antimetabolite.

Patent coverage: 29,805 distinct patent families (120,716 SureChEMBL compound mentions), from 2 matched compound structure(s). One matched structure accounts for 120,496 (100%) of the total. Mentions count patents naming the compound (not distinct inventions), so promiscuous / reference molecules inflate the mention figure — families are the dedup metric.
