b) Western blot analysis documenting cleavage of caspase-8, caspase-9, caspase-3, and PARP by nelarabine. Cells were treated with nelarabine (5 μM for JURKAT, P12-ICHIKAWA, and DND-41 cells, 2 μM MOLT-4 cells) for the indicated times, collected, and then lysed. Fifty micrograms of each lysate were electrophoresed on SDS-PAGE gels followed by transfer onto a nitrocellulose membrane. c) Nelarabine induces a decrease in the phosphorylation status of critical components of the PI3K/AKT/mTOR signaling pathway, as well as p-ERK (Thr202) levels in T-ALL sensitive cell lines. Western blot analysis documenting the reduction of p-AKT (Ser473), p-S6RP, p-GSK3β (Ser9), and p-ERK (Thr202). Antibody to β-actin served as a loading control.

|Description||Nelarabine (506U78) is a purine nucleoside analog and DNA synthesis inhibitor with IC50 from 0.067-2.15 μM in tumor cells.|
|Features||Nelarabine is rapidly converted into ara-G through demethoxylation by adenosine deaminase.|
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 Nelarabine than B-lineage but there is considerable overlap. The efficacy of NEL in T-lineage and B-lineage cell lines is 25-fold and 113-fold less than ARAC, respectively.  Nelarabine acts by inhibiting DNA synthesis and inducing apoptosis in susceptible cells. Nelarabine 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 Nelarabine 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 Nelarabine is 77 minutes and of ara-G is 232 minutes. The AUCcsf:AUCplasma is 29 % for Nelarabine and 23 % for ara-G. Nelarabine and ara-G do not accumulate with daily infusions because of their relatively short half-lives. |
|In vitro||DMSO||60 mg/mL (201.83 mM)|
|Water||3 mg/mL (10.09 mM)|
|In vivo||Add solvents to the product individually and in order(Data is from Selleck tests instead of citations):
For best results, use promptly after mixing.
* Please note that Selleck tests the solubility of all compounds in-house, and the actual solubility may differ slightly from published values. This is normal and is due to slight batch-to-batch variations.

2.Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such as vortex, ultrasound or hot water bath can be used to aid dissolving.
Calculate the mass, volume or concentration required for a solution. The Selleck molarity calculator is based on the following equation:
Mass (mg) = Concentration (mM) × Volume (mL) × Molecular Weight (g/mol)
*When preparing stock solutions, please always use the batch-specific molecular weight of the product found on the via label and SDS / COA (available on product pages).
Calculate the dilution required to prepare a stock solution. The Selleck dilution calculator is based on the following equation:
Concentration (start) x Volume (start) = Concentration (final) x Volume (final)
This equation is commonly abbreviated as: C1V1 = C2V2 ( Input Output )
* When preparing stock solutions always use the batch-specific molecular weight of the product found on the vial label and SDS / COA (available online).

Definitions of molecular mass, molecular weight, molar mass and molar weight:
Molecular mass (molecular weight) is the mass of one molecule of a substance and is expressed in the unified atomic mass units (u). (1 u is equal to 1/12 the mass of one atom of carbon-12)
Molar mass (molar weight) is the mass of one mole of a substance and is expressed in g/mol.
