Fludarabine phosphate is a prodrug form of fludarabine (Item No. 14128) and 2-fluoro-ara-ATP.{67157} It is dephosphorylated in vivo to fludarabine and re-phosphorylated intracellularly to the active form, 2-fluoro-ara-ATP, which inhibits DNA synthesis.{62875,67158} Fludarabine phosphate reduces viability of, and induces apoptosis in, N-Myc-overexpressing LASCPC-01 neuroendocrine prostate cancer cells (IC50 = 17.67 µM).{67157} It also reduces N-Myc protein levels when used at a concentration of 25 µM for at least 48 hours but does not reduce the levels of N-Myc mRNA. Fludarabine phosphate (120 mg/kg per day) reduces tumor volume in N-Myc-overexpressing 22Rv1-N-Myc and LASCPC-01, but not non-N-Myc-overexpressing 22Rv1, mouse xenograft models. Fludarabine phosphate is also an inhibitor of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) RNA-dependent RNA polymerase (RdRp; EC50 = 0.93 µM).{62876} Formulations containing fludarabine phosphate have been used in the treatment of B cell chronic lymphocytic leukemia (CLL).
