Biological Activity

Description Fludarabine Phosphate is an analogue of adenosine and deoxyadenosine, which is able to compete with dATP for incorporation into DNA and inhibit DNA synthesis.
Targets
DNA polymerase α [1]
(Cell-free assay)		 DNA polymerase δ [1]
(Cell-free assay)
1.1 μM(Ki ) 1.3 μM(Ki)
In vitro Fludarabine Phosphate is converted to F-ara-ATP in cells and then incorporated into DNA in a self-limiting manner. Fludarabine Phosphate competes with dATP for incorporation into the A site of the extending DNA strand, which results in termination of DNA strand elongation. Human DNA polymerase α incorporates more Fludarabine Phosphate into DNA than polymerase δ. Fludarabine Phosphate completively inhibits DNA polymerase α and DNA polymerase δ with Ki of 1.1 μM and 1.3 μM, respectively. DNA polymerase δ is also able to excise the incorporated Fludarabine Phosphate from DNA in vitro. [1]
In vivo Fludarabine Phosphate is toxic for tumor-free mice. The maximum tolerated dose (LD10) Fludarabine Phosphate administered as a single dose is 234 mg/kg. The 50% lethal dose is 375 mg/kg. Fludarabine Phosphate administered as a single dose induces fewer number of cells surviving therapy in mice bearing P388 leukemia, accompanied by greater percentage of increase in life span (110%) and increased median survival time.

Protocol (from reference)

Cell Assay:[1]
  • Cell lines

    Human T lymphoblastoid cells

  • Concentrations

    30 μM

  • Incubation Time

    5 hours

  • Method

    Cells are incubated with Fludarabine Phosphate for 5 hr and washed twice with drug-free warm medium. 800 cells are mixed with 1.3 mL of 0.25% soft agar in Dulbecco’s medium supplemented with 20% fetal bovine serum (pre-warmed to 37 ℃) and incubated in a tissue culture dish for 10 days (humidified 5% CO2 , 37 ℃). At the end of the incubation period, colonies of more than 40 cells are scored under a microscope. The cytotoxic effect of the drugs is expressed as a percentage of survival relative to that of untreated control cells.
Animal Study:[3]
  • Animal Models

    Murine Leukemia P3881

  • Dosages

    234 mg/kg

  • Administration

    A single dose i.p. at day 1
