Mechanism of Action

Features	Nelarabine is rapidly converted into ara-G through demethoxylation by adenosine deaminase.
Targets/IC₅₀/Ki	DNA synthesis (PER-255 cells) 67 nM DNA synthesis (HSB2 cells) 0.44 μM DNA synthesis (ALL-SIL cells) 1.24 μM DNA synthesis (JURKAT cells) 2.15 μM
In vitro	The IC50 of Nelarabine is 25-fold and 113-fold higher than ARAC in T- and B-lineage, respectively. T-ALL cells are eightfold more sensitive to this compound than B-lineage but there is considerable overlap. The efficacy of this chemical in T-lineage and B-lineage cell lines is 25-fold and 113-fold less than ARAC, respectively. It acts by inhibiting DNA synthesis and inducing apoptosis in susceptible cells. This agent demonstrated significant antineoplastic activity with acceptable toxicity.
In vivo	The Nelarabine plasma AUC is 2.82 mM minutes and the ara-G plasma AUC is 20 mM minutes. The terminal half-life of this compound in plasma is 25 min, clearance is 42 mL/minutes/kg, and central volume of distribution is 1.1 L/kg. The terminal half-life of ara-G in plasma is 182 minutes and the central volume of distribution is 1.4 L/kg. In CSF the terminal half-life of this chemical is 77 minutes and of ara-G is 232 minutes. The AUCcsf:AUCplasma is 29 % for this agent and 23 % for ara-G. This compound and ara-G do not accumulate with daily infusions because of their relatively short half-lives.
