Ara-G (9-β-D-Arabinofuranosyl guanine) is an inducer of apoptosis, inhibitor of DNA synthesis, an antimetabolite, and antineoplastic. 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 cellular accumulation of Ara-GTP is indicative of the clinical response to treatment with nelarabine, the prodrug. The differential accumulation and consequent selective cytotoxicity of Ara-G in T cells has been postulated to be due to the higher accumulation and slower elimination of ara-GTP in these cells. Nelarabine was developed because of poor water solubility of Ara-G, but Ara-G is DMSO-soluble. Nelarabine is approved in the United States for the treatment of T-cell acute lymphoblastic leukemia (T-ALL) and T-cell lymphoblastic lymphoma (T-LBL).
