ProductName Cytarabine Cat No CEI-0319 Description Cytarabine CAS No 147-94-4 Molecular Weight 243.22 Purity >99% Storage 2 years at -20centigrade Powder Targets DNA synthesis Molecular Formula C9H13N3O5 Solubility DMSO 1 mg/mL, Water 48 mg/mL, Ethanol In vitro Cytarabine (AraC) is phosphorylated into a triphosphate form (Ara-CTP) involving deoxycytidine kinase (dCK), which competes with dCTP for incorporation into DNA, and then blocks DNA synthesis by inhibiting the function of DNA and RNA polymerases. Cytarabine displays a higher growth inhibitory activity towards wild-type CCRF-CEM cells compared to other acute myelogenous leukemia (AML) cells with IC50 of 16 nM. category Antineoplastic Agents(c1417) cas_num 147-94-4 ECHEMI Editorial ReferenceCytarabine is a chemotherapy drug used to treat acute myeloid leukaemia, acting by inhibiting DNA synthesis with an IC50 of 16 nM.

Cytarabine appears as colorless crystals. Used as an antiviral agent.|Cytarabine is a pyrimidine nucleoside in which cytosine is attached to D-arabinofuranose via a beta-N(1)-glycosidic bond. Used mainly in the treatment of leukaemia, especially acute non-lymphoblastic leukaemia, cytarabine is an antimetabolite antineoplastic agent that inhibits the synthesis of DNA. It also has antiviral and immunosuppressant properties. It has a role as an antineoplastic agent, an antimetabolite, an antiviral agent and an immunosuppressive agent. It is a beta-D-arabinoside, a pyrimidine nucleoside and a monosaccharide derivative. It derives from a cytosine.|A pyrimidine nucleoside analog that is used mainly in the treatment of leukemia, especially acute non-lymphoblastic leukemia. Cytarabine is an antimetabolite antineoplastic agent that inhibits the synthesis of DNA. Its actions are specific for the S phase of the cell cycle. It also has antiviral and immunosuppressant properties. (From Martindale, The Extra Pharmacopoeia, 30th ed, p472)|Cytarabine is a Nucleoside Metabolic Inhibitor. The mechanism of action of cytarabine is as a Nucleic Acid Synthesis Inhibitor.|Cytarabine is a cytosine analogue and antineoplastic agent used largely in the therapy of acute leukemia. Cytarabine is associated with a low rate of transient serum enzyme and bilirubin elevations during therapy, but has only rarely been implicated in cases of clinically apparent acute liver injury with jaundice.|Cytarabine is an antimetabolite analogue of cytidine with a modified sugar moiety (arabinose instead of ribose). Cytarabine is converted to the triphosphate form within the cell and then competes with cytidine for incorporation into DNA. Because the arabinose sugar sterically hinders the rotation of the molecule within DNA, DNA replication ceases, specifically during the S phase of the cell cycle. This agent also inhibits DNA polymerase, resulting in a decrease in DNA replication and repair. (NCI04)Basic Info-
