Fludarabine (Synonyms: 2-fluoro-ara-A, NSC 118218) |
| Catalog No.GC14144 |
La fludarabine (NSC 118218) est un inhibiteur de la synthèse de l'ADN et un analogue fluoré de la purine ayant une activité antinéoplasique dans les tumeurs malignes lymphoprolifératives. La fludarabine inhibe l'activation induite par les cytokines de la transcription des gènes STAT1 et STAT1-dépendante dans les lymphocytes normaux au repos ou activés.

Fludarabine is a purine analog that inhibits DNA synthesis [1].
DNA synthesis is a natural creation of deoxyribonucleic acid (DNA) molecules and plays an important role in cell growth.
Fludarabine is a prodrug and is phosphorylated to the nucleoside triphosphate (F-ara-ATP) in cells to elicit biological activity. It affected a series of enzymes that required in DNA synthesis such as DNA primase, DNA polymerases, DNA ligase I, ribonucleotide reductase and 3’-5’ exonuclease activity of DNA polymerases δ and ε [1]. In human myeloma cell RPMI8226, fludarabine significantly inhibited cells growth and reduced phosphorylation of Akt. Also, it reduced XIAP and survivin, the inhibitors of apoptosis proteins (IAP) family [2]. Fludarabine can act as a cytosolic 50-nucleotidase II (cN-II) inhibitor [3].
In immunodeficient mice bearing RPMI8226 myeloma xenografts, fludarabine (40 mg/kg) slowed down the growth of tumors by about 5-fold in 25 d comparing with the control tumors [2].
