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.

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.
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
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

Our previous data from a human leukemic cell line made resistant to the nucleoside analog (NA) 9-β-D-arabinofuranosylguanine (AraG) revealed a massive upregulation of fetal hemoglobin (HbF) genes and the ABCB1 gene coding for the multidrug resistance P-glycoprotein (P-gp). The expression
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

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
