Biological Activity

Description NSC 632839 is not only a DUB inhibitor, but also a deSUMOylase inhibitor, it inhibits USP2, USP7, and SENP2 with EC50 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.
Targets

(Cell-free assay)		 USP7 [1]

In vitro
In vitro 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. [1] 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. [2]

Method for preparing DMSO master liquid: mg drug pre-dissolved in μL DMSO ( Master liquid concentration mg/mL, Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug. )

Method for preparing in vivo formulation: Take μL DMSO master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O, mix and clarify.

Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.

Note: 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.
