Chemical Structure
Fludarabine triphosphate
Synonym(s): F-ara-ATP
- CAS No.: 74832-57-8
- Formula:C10H15FN5O13P3
- Molecular Weight:525.17
IUPAC Name: ((2R,3S,4S,5R)-5-(6-amino-2-fluoro-9H-purin-9-yl)-3,4-dihydroxytetrahydrofuran-2-yl)methyl tetrahydrogen triphosphate
InChIKey: PIOKUWLZUXUBCO-FJFJXFQQSA-N
SMILES: O[C@@H]([C@@H]1O)[C@](O[C@@H]1CO[P](O[P](O[P](O)(O)=O)(O)=O)(O)=O)([H])N2C3=NC(F)=NC(N)=C3N=C2
Biological Activity: Fludarabine triphosphate (F-ara-ATP), the active metabolite of Fludarabine (HY-B0069), is a potent, noncompetitive and specific inhibitor of DNA primase, with an IC50 of 2.3 μM and a Ki of 6.1 μM. Fludarabine triphosphate inhibits DNA synthesis by blocking DNA primase and primer RNA formation. Fludarabine triphosphate inhibits ribonucleotide reductase and DNA polymerase and ultimately leads to cellular apoptosis[1][2].
