Antineoplastic Agent, Antimetabolite (purine)

Antimetabolites are antineoplastic agent that inhibit cell growth and proliferation.

Fludarabine (Fludara)

Fludarabine contains fludarabine phosphate, a fluorinated nucleotide analogue of the antiviral agent vidarabine, 9-b-D-arabinofuranosyladenine (ara-A) that enters the cell and is phosphorylated to form the active metabolite 2-fluoro-ara-adenosine triphosphate, which inhibits deoxyribonucleic acid (DNA) synthesis. Specifically, this agent inhibits DNA polymerase, DNA primase, DNA ligase, and ribonucleotide reductase, as well as ribonucleic acid (RNA) function, RNA processing, and mRNA translation. Fludarabine also activates apoptosis.
