Deoxycytidine kinase (dCK) substrate. Phosphorylated to form clofarabine triphosphate, which competes with dATP for DNA polymerase-α and -ε and potently inhibits ribonucleotide reductase (IC50 = 65 nM). Induces apoptosis by directly altering mitochondrial transmembrane potential. Demonstrates growth inhibition and cytotoxic activity in a variety of leukemias and solid tumors.

Preparing Stock Solutions
The following data is based on the product molecular weight 303.68. Batch specific molecular weights may vary from batch to batch due to solvent of hydration, which will affect the solvent volumes required to prepare stock solutions.
|Concentration / Solvent Volume / Mass||1 mg||5 mg||10 mg|
|1 mM||3.29 mL||16.46 mL||32.93 mL|
|5 mM||0.66 mL||3.29 mL||6.59 mL|
|10 mM||0.33 mL||1.65 mL||3.29 mL|
|50 mM||0.07 mL||0.33 mL||0.66 mL|
