Description

Biochem/physiol Actions

Deoxyadenosine analog resistant to adenosine deaminase; antileukemic with immunosuppressive activity

Application

2-Chloro-2′-deoxyadenosine (2-CdA) is a chlorinated purine nucleoside with activity against lymphoproliferative disorders, such as hairy cell leukemia (HCL) and multiple myeloma (MM). 2-CdA resists ADA degradation and is phosphorylated to CdATP in lymphocytes. CdATP incorporation into DNA induces strand breaks and the activation of apoptosis. 2-CdA may also be used in studies involving the inhibition of DNA polymerase(s).
Cladribiane, like fludarabine, is a prodrug that is must be phosphorylated intracellularly to the monophosphate by the nuclear/cytosol enzyme deoxycytidine kinase (dCK) and possibly by the mitochondrial enzyme deoxyguanosine kinase (dGK).

Cladribiane, like fludarabine, is a prodrug that is must be phosphorylated intracellularly to the monophosphate by the nuclear/cytosol enzyme deoxycytidine kinase (dCK) and possibly by the mitochondrial enzyme deoxyguanosine kinase (dGK). Clinically used for treatment of hairy cell leukemia, chronic lymphocytic leukemia and other indolent leukemias.
