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 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 9-beta-D-arabinofuranosylguanine (ara-G), an active compound of nelarabine, demonstrates potent cytotoxicity specifically on T-cell malignancies. In cells, ara-G is phosphorylated to ara-G triphosphate (ara-GTP), which is subsequently incorporated into DNA, thereby inhibiting DNA synthesis. Because ara-GTP is crucial to ara-G's

We studied acceptance of various deoxyguanosine analogues by the unique guanosine preferring nucleoside transport system exhibited by NB4 cells, csg. Indirect assessment of acceptance using transport inhibition assays revealed that both 1-beta-D-arabinofuranosylguanine (ara-G) and 4'-thio-beta-D-xylofuranosylguanine (thio-xyl-G) compete with guanosine for

Incubation of cells with thymidine (dThd) is known to cause dNTP pool imbalance as well as deletions and depletion of the mtDNA. In order to gain further understanding in the events involved in dThd toxicity over time, H9 cells were

Forodesine and nelarabine (the pro-drug of ara-G) are 2 nucleoside analogues with promising anti-leukemic activity. To better understand which pediatric patients might benefit from forodesine or nelarabine (ara-G) therapy, we investigated the in vitro sensitivity to these drugs in 96

9-(β-D-Arabinofuranosyl)guanine (AraG) is a guanosine analog that has a proven efficacy in the treatment of T-cell lymphoblastic disease. To test the possibility of using a radiofluorinated AraG as an imaging agent, we have synthesized 2'-deoxy-2'-[(18)F]fluoro-9-β-D-arabinofuranosylguanine ([(18)F]F-AraG) and investigated its uptake
