1. Cladribine

   Cladribine, sold under the brand name Leustatin, among others, is a medication used to treat hairy cell leukemia (leukemic reticuloendotheliosis) and B-cell chronic lymphocytic leukemia.Cladribine, sold under the brand name Mavenclad, is indicated for the treatment of adult patients with highly active forms of relapsing-remitting multiple sclerosis.Cladribine (2-chloro-2'-deoxyadenosine [2-CdA]) is a purine analogue that selectively targets and suppresses lymphocytes implicated in the underlying pathogenesis of multiple sclerosis and B-cell leukaemia. Chemically, it mimics the nucleoside adenosine. However, unlike adenosine, it is relatively resistant to breakdown by the enzyme adenosine deaminase, which causes it to accumulate in targeted cells and interfere with the cell's ability to process DNA.Cladribine is taken up by cells via transporter proteins. Once inside a cell, cladribine undergoes phosphorylation by the enzyme deoxycytidine kinase (DCK) to produce mononucleotide 2-chlorodeoxyadenosine 5’monophosphate (2-CdAMP), which is subsequently phosphorylated to the triphosphorylated active compound 2-chlorodeoxyadenosine 5’triphosphate (2-CdATP). Activated cladribine is incorporated into cellular DNA, which triggers apoptosis. Accumulation of cladribine into cells is dependent on the ratio of DCK and 5'-nucleotidase (5’-NT), which breaks down and inactivates the compound. This ratio differs between cell types, with high levels in T and B lymphocytes, resulting in selective targeting of these cells. In contrast, DCK:5'NT is relatively low in other cell types, thus sparing numerous non-haematological cells.

1. Cladribine

   Cladribine is a drug used to treat hairy cell leukemia and multiple sclerosis. Its chemical name is 2-chlorodeoxyadenosine. As a purine analog, it is a synthetic anti-cancer agent that also suppresses the immune system. Chemically, it mimics the nucleoside adenosine and thus inhibits the enzyme adenosine deaminase, which interferes with the cell's ability to process DNA. It is easily destroyed by normal cells except for blood cells, with the result that it produces relatively few side effects and results in very little non-target cell loss.
