Background:

Cytarabine-13C3 is intended for use as an internal standard for the quantification of cytarabine by GC- or LC-MS. Cytarabine is a nucleoside analog that differs from cytosine by the presence of a hydroxyl group at the 2' position of the sugar residue. It is triphosphorylated in vivo to produce ara-C, a competitive inhibitor of DNA polymerases α and β (Kis = 4 and 32 μM, respectively).1,2,3 At low concentrations, ara-C is incorporated into DNA, slowing but not stopping DNA synthesis.4 It has antiviral activity against certain types of viruses.5 Formulations containing cytarabine have been used in the treatment of leukemia.4
