Ara-G: An Inhibitor of DNA Replication in T-Leukemic Cells

Arabinosylguanine (ara-G) is triphosphorylated by multiple kinases intracellularly to the active nucleotide, ara-GTP, which inhibits the DNA replication in T-leukemic cells. Ara-G is used for the treatment of T-cell acute lymphoblastic leukemia (T-ALL) or T-cell lymphoblastic lymphoma (T-LBL). From the 2000s, nelarabine (the 6-methoxy pro-drug of ara-G) have been introduced and used for the treatment of T-All and T-LBL. In organic synthesis, ara-G is used as an intermediate for the synthesis of guanosine analogs. (The product is for research purpose only.)
