Application

Ara-G is converted by cellular kinases to the active 5′-triphosphate, Ara-GTP. This active form of Ara-G induces apoptosis and inhibits DNA synthesis. Ara-G is also an antineoplastic and antimetabolite.

Biochem/physiol Actions

Ara-G is an inducer of apoptosis; inhibitor of DNA synthesis; antineoplastic; and antimetabolite.
Ara-G is an inducer of apoptosis; inhibitor of DNA synthesis; antineoplastic; and antimetabolite. Ara-G is converted by cellular kinases to the active 5′-triphosphate, Ara-GTP. Incorporation of Ara-GTP into DNA leads to inhibition of DNA synthesis and apoptosis.

The anti-leukemic nucleoside analogs 1-beta-D-arabinofuranosylcytosine (araC) and 9-beta-D-arabinofuranosylguanine (araG) are dependent on intracellular phosphorylation for pharmacological activity. AraC is efficiently phosphorylated by deoxycytidine kinase (dCK). Although araG is phosphorylated by dCK in vitro, it is a preferred substrate of mitochondrial

GW506U78 or nelarabine (Glaxo-SmithKline) is a nucleoside analog that is rapidly converted by cells of lymphoid lineage to its corresponding arabinosylguanine nucleotide triphosphate (araGTP). The triphosphate form of araG acts as a substrate for DNA polymerases and araG gets incorporated

Nelarabine is a water-soluble prodrug of the cytotoxic deoxyguanosine analog ara-G, to which it is rapidly converted in vivo by adenosine deaminase. Nelarabine has shown activity in the treatment of T-cell malignancies, especially T-cell acute lymphoblastic leukemia. Preliminary data suggested

The deoxyguanosine (GdR) analog guanine-ß-d-arabinofuranoside (araG) has a specific toxicity for T lymphocytes. Also GdR is toxic for T lymphocytes, provided its degradation by purine nucleoside phosphorylase (PNP) is prevented, by genetic loss of PNP or by enzyme inhibitors. The

Unlike the preparation of other purine nucleosides, transglycosylation from a pyrimidine nucleoside and guanine is difficult because of the low solubility of this base. Thus, another strategy, based on the coupled action of two whole cell biocatalyzed reactions, transglycosylation and
