Cladribine is an adenosine deaminase inhibitor.Adenosine deaminase is an enzyme that involved in purine metabolism.
Cladribine is a well-known purine nucleoside analog with particular activity against lymphoproliferative disorders, such as hairy cell leukemia (HCL). In U266, RPMI8226 and MM1.S cells, Cladribine inhibited cell proliferation in a dose-dependant way with IC50 value of 2.43, 0.75 and 0.18 μmol/L, respectively. Apoptosis assays showed that Cladribine induced apoptosis of U266, RPMI8226 and MM1.S cells in a dose-dependant way . In MM1.S cells, Cladribine (0.2uM) induces activation of caspase-3, -8, and -9 and PARP cleavage in a time-dependent way and reduces the phospho-STAT3 levels in a dose-dependent way. Also, Cladribine induces accumulation of DNA strand breaks and then activates the tumor suppressor p53 in lymphocytes .
In the treatment of indolent lymphoid malignancies, lower doses of Cladribine (5 mg/m2/week) are highly active and possibly better tolerated than standard doses .
