Mechanism of action

Fludarabine is a fluorinated nucleoside analog that is phosphorylated intracellularly to its active form, fludarabine triphosphate. This active metabolite inhibits both ribonucleotide reductase and DNA polymerase, preventing DNA synthesis and repair. The drug is particularly effective against lymphoid malignancies because lymphocytes have high levels of deoxycytidine kinase, the enzyme responsible for its activation.
