개요Fludarabine phosphate is an antimetabolite indicated for the treatment of B cell lymphocytic leukemia. It is reportedly effective in patients refractory to other therapies. Fludarabine phosphate acts by inhibiting primer RNA synthesis. Its side effects include bone marrow suppression, anemia, thrombocytopenia and neutropenia.
용도Fludarabine phosphate is used for the treatment of chronic lymphatic leukemia and low-grade lymphoma. In the circulation,fludarabine phosphate is immediately dephosphorylated to the nucleoside fludarabine. About 30-40% of nucleoside fludarabine is excreted into the urine. In addition, fludarabine is metabolized into a hypoxanthine metabolite also excreted in the urine.Intracellularly,fludarabine is stepwise rephosphorylated to the active triphosphate. Deoxycytidine kinase is the dominant, if not the exclusive,enzyme for the formation of the monophosphate. Adenylate kinase and nucleoside diphosphate kinase are believed to be involved in the formation of the diphosphate and triphosphate,respectively.

정의ChEBI: Fludarabine phosphate is a purine arabinonucleoside monophosphate having 2-fluoroadenine as the nucleobase. A prodrug, it is rapidly dephosphorylated to 2-fluoro-ara-A and then phosphorylated intracellularly by deoxycytidine kinase to the active triphosphate, 2-fluoro-ara-ATP. Once incorporated into DNA, 2-fluoro-ara-ATP functions as a DNA chain terminator. It is used for the treatment of adult patients with B-cell chronic lymphocytic leukemia (CLL) who have not responded to, or whose disease has progressed during, treatment with at least one standard alkylating-agent containing regimenas. It has a role as an antimetabolite, an antineoplastic agent, an immunosuppressive agent, an antiviral agent, a prodrug and a DNA synthesis inhibitor. It is an organofluorine compound, a nucleoside analogue and a purine arabinonucleoside monophosphate. It derives from a 2-fluoroadenine.
