|Description||NSC 632839 is not only a DUB inhibitor, but also a deSUMOylase inhibitor, it inhibits USP2, USP7, and SENP2 with IC50 of 45 μM, 37 μM, and 9.8 μM, respectively.|
|Features||Less potent than NSC 144303 in inducing apoptosis of E1A and E1A/C9DN cells.|
NSC 632839 inhibits purified USP2- and USP7-mediated cleavage of Ub-PLA2. NSC 632839 does not inhibit the reporter enzyme PLA2 over the concentration range tested (1.2–150 μM), indicating that the reported inhibition is selective for isopeptidases.  NSC 632839 is capable of sustaining caspase-3/caspase-7 activity in the absence of a functional caspase-9 in E1A and E1A/C9DN cells. NSC 632839 induces apoptosis with IC50 of 15.65 μM and 16.23 μM in E1A and E1A/C9DN cells, respectively. NSC-632839 (10 μM) provokes the accumulation of polyubiquitins in E1A cells expressing HA-tagged ubiquitin. NSC-632839 (10 μM) dramatically increases the levels of Noxa and Mcl-1 in E1A cells during a time course analysis. NSC-632839 (10 μM) provokes mitochondrial fragmentation in a higher percentage of cells with an intact outer mitochondrial membrane compared with etoposide.

1.Please make sure the liquid is clear before adding the next solvent.
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 MSDS / 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 MSDS / 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.
