Product Description

BAY 11-7082 (BAY-11-7082; BAY-117082) is a novel and potent NF-κB inhibitor with potential anti-inflammatory and anticancer activity. In tumor cells, it has an IC50 of 10 M and prevents TNFα from causing IB phosphorylation.

Biological Activity I Assay Protocols (From Reference)
Targets
USP7 (IC50 = 0.19 μM); USP21(IC50 = 0.96 μM); Autophagy; NF-κB
ln Vitro
BAY 11-7082 completely and specifically abrogates NF-κB DNA binding, downregulating the NF-κB-inducible cytokine IL-6 and inducing apoptosis.[1]
BAY 11-7082 (< 8 μM) can effectively inhibit NF-κB luciferase activity at both basal and TNFα -stimulated levels in a dose-dependent manner. The rate of proliferation in NCI-H1703 cells is significantly inhibited by BAY 11-7082 (8 μM).[2]
Bay 11-7082 (5 μM) has little impact on the DNA binding of another transcription factor, AP-1, it rapidly and effectively decreases the DNA binding of NF-kappaB in HTLV-I-infected T-cell lines and downregulates the expression of the antiapoptotic gene Bcl-x(L). BPrimary ATL cells are more susceptible to the apoptosis caused by Bay 11-7082 than are healthy peripheral blood mononuclear cells, and this apoptosis is also accompanied by a down-regulation of NF-kappaB activity. With the expression of cyclin D1, cyclin D2, and Bcl-xL being downregulated, Bay 11-7082 (5 μM) specifically causes apoptosis in HTLV-I-infected T-cell lines.[3]
In mouse hippocampal slices, BAY 11-7082 (100 μM) inhibits the nuclear translocation of p65 induced by NMDA as well as the NMDA-induced rise in NF-κB binding. With 40% neuroprotection at 20 μM and 70% neuroprotection at 100 M, BAY 11-7082 inhibits NMDA toxicity in the CA1 region of hippocampal slices.[4]
In adipose tissue, BAY 11-7082 significantly inhibits NF-κB p65 DNA-binding activity at all tested concentrations, whereas BAY 11-7082 significantly inhibits NF-κB p65 DNA-binding activity in skeletal muscle at 50 μM and 100 μM. Human adipose tissue and skeletal muscle IKK-βprotein levels are decreased by BAY 11-7082 (100 μM). TNF-release from adipose tissue is significantly reduced by BAY 11-7082 (100 μM), whereas the release of IL-6 and IL-8 is significantly inhibited at all BAY 11-7082 concentrations tested. The skeletal muscle release of TNF-α, IL-6, and IL-8 is markedly reduced by BAY 11-7082 (50 μM). [5]
ln Vivo
In gastric cancer cells, BAY 11-7082, an NF-B inhibitor, causes apoptosis and S phase arrest.
Enzyme Assay
UBE1 (0.17 μM) in 22.5 μL of 20 mM Hepes, pH 7.5, containing 10 μM ubiquitin is incubated for 45 min at 21°C with 1 μL of DMSO or 1 μL of BAY 11-7082 in DMSO. A 2.5 μL solution of 10 mM magnesium acetate and 0.2 mM ATP is added, incubated for 10 min at 30°C, and the reactions are terminated by the addition of 2.5 μL of 10% (w/v) SDS and heating for 6 min at 75°C. The samples are subjected to SDS/PAGE in the absence of any thiol. The gels are stained for 1 h with Coomassie Instant Blue and destained by washing with water. The loading of ubiquitin to E2 conjugating enzymes is carried out in an identical manner, except that UBE1 (0.17 μM) is mixed with Ubc13 (2.4 μM) or UbcH7 (2.9 μM) prior to incubation with BAY 11-7082.
Cell Assay
In 96-well microtiter plates, siRNA is transfected into the cells, which are then cultured for 72 hours in complete NSCLC medium and given a 12-hour BAY 11-7082 treatment. Three hours are spent incubating the cells with [3H]thymidine. The radioactivity on the filters is determined by β-scintillation counting after the cells are collected on filters using an automatic cell harvester.
Animal Protocol
Male BALB/c nude mice.

*Note: Please select an appropriate solvent for the preparation of stock solution based on your experiment needs. For most products, DMSO can be used for preparing stock solutions (e.g. 5 mM, 10 mM, or 20 mM concentration); some products with high aqueous solubility may be dissolved in water directly. Solubility information is available at the above Solubility Data section. Once the stock solution is prepared, aliquot it to routine usage volumes and store at -20°C or -80°C. Avoid repeated freeze and thaw cycles.

Calculator

Molarity Calculator allows you to calculate the mass, volume, and/or concentration required for a solution, as detailed below:

  • Calculate the Mass of a compound required to prepare a solution of known volume and concentration
  • Calculate the Volume of solution required to dissolve a compound of known mass to a desired concentration
  • Calculate the Concentration of a solution resulting from a known mass of compound in a specific volume
An example of molarity calculation using the molarity calculator is shown below:
What is the mass of compound required to make a 10 mM stock solution in 5 ml of DMSO given that the molecular weight of the compound is 350.26 g/mol?
  • Enter 350.26 in the Molecular Weight (MW) box
  • Enter 10 in the Concentration box and choose the correct unit (mM)
  • Enter 5 in the Volume box and choose the correct unit (mL)
  • Click the “Calculate” button
  • The answer of 17.513 mg appears in the Mass box. In a similar way, you may calculate the volume and concentration.

Dilution Calculator allows you to calculate how to dilute a stock solution of known concentrations. For example, you may Enter C1, C2 & V2 to calculate V1, as detailed below:

What volume of a given 10 mM stock solution is required to make 25 ml of a 25 μM solution?
Using the equation C1V1 = C2V2, where C1=10 mM, C2=25 μM, V2=25 ml and V1 is the unknown:
  • Enter 10 into the Concentration (Start) box and choose the correct unit (mM)
  • Enter 25 into the Concentration (End) box and select the correct unit (mM)
  • Enter 25 into the Volume (End) box and choose the correct unit (mL)
  • Click the “Calculate” button
  • The answer of 62.5 μL (0.1 ml) appears in the Volume (Start) box
