Structure of Nelarabine (CAS NO.121032-29-2):
                   

 Nelarabine (CAS NO.121032-29-2) is used as a chemotherapy drug in T-cell acute lymphoblastic leukemia.

 Nelarabine , its cas register number is 121032-29-2. It also can be called (2R,3S,4R,5R)-2-(2-amino-6-methoxy-purin-9-yl)-5-(hydroxymethyl)oxolane-3,4-diol ; Arranon ; and TAtriance . It was previously known as 506U78, and is a purine nucleoside analog converted to its corresponding arabinosylguanine nucleotide triphosphate (araGTP), resulting in inhibition of DNA synthesis and cytotoxicity. In October 2005, Nelarabine (CAS NO.121032-29-2) was approved by the FDA for T-cell acute lymphoblastic leukemia and T-cell lymphoblastic lymphoma that has not responded to or has relapsed following treatment with at least two chemotherapy regimens. It was later approved in the European Union on August 22, 2007.
