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.

Cladribine (2-chloro-2'-deoxyadenosine) is an adenosine deaminase-resistant analogue of deoxyadenosine. In the treatment of hairy cell leukaemia, cladribine has demonstrated excellent efficacy (complete response in 33 to 92% of patients) in noncomparative studies. Cladribine appears to compare favourably with other systemic

The adenosine deaminase-resistant purine deoxynucleoside 2-chloro-2'-deoxyadenosine (CdA) is markedly toxic in vitro to nondividing and proliferating normal human lymphocytes and to many leukemia cell specimens. The CdA is also effective against mouse L1210 leukemia in vivo. The present investigations have
