使用Cytarabine USP (Cytosar)is used to treat Acute granulocytic leukemia (adults); acute lymphocytic leukemia (children); Hodgkin’s disease
一般的な説明Cytarabine is a pyrimidine nucleoside drug that is related toidoxuridine. This agent is primarily used as an anticanceragent for Burkitt lymphoma and myeloid and lymphaticleukemias. Cytarabine blocks the cellular utilization of deoxycytidine,hence inhibiting the replication of viral DNA.Before it becomes active, the drug is converted to monophosphates,diphosphates, and triphosphates, which block DNApolymerase and the C-2 reductase that converts cytidinediphosphate into the deoxy derivative. The antiviral use of cytarabine is in the treatment of herpeszoster (shingles), herpetic keratitis, and viral infectionsthat resist idoxuridine. Cytarabine is usually administeredtopically. Toxicity occurs on bone marrow, the gastrointestinal(GI) tract, and the kidneys.
純化方法Purify cytarabin by recrystallisation from aqueous EtOH or a large volume of H2O (it solubility at ~20o is 5%). It has max 212 and 279nm at pH 2 and 272nm at pH 12. It is an acute leukaemic agent. [Walwick et al. Proc Chem Soc (London) 84 1959, Beilstein 25 III/IV 3669.]
