| Description | BAY 11-7082 (19542-67-7)inhibits cytokine-induced IκB-α phosphorylation via inhibition of IκB Kinase which results in inhibition of NFκB .1 Inhibits anchorage-independent growth of mammary epithelial cells induced with 4-hydroxyestradiol via inhibition of NFκB activation.2 Inhibits IFNα production and blocks nuclear translocation of IRF7 in plasmacytoid dendritic cells.3 Facilitates wound healing by inhibiting TNFα-induced MMP expression.4 A useful tool for probing the involvement of NFκB in physiological and pathophysiological processes.5 Cell permeable. | | Uses | Bay 11-7082 has been used as:
- a nuclear factor-kappa B (NF-kB) inhibitor to verify the action of the NF-kB signaling pathway in the production of interleukin (IL)-8
- a nuclear factor-kappa B (NF-kB) inhibitor to study the role of NF-kB activation in Mycoplasma hyorhinis -induced epithelial-mesenchymal transition (EMT) and cell migration
- a nod-like receptor family pyrin domain containing 3 (NLRP3) selective inhibitor to examine its effects on liver inflammation in mice after hematopoietic stem cell transplantation
| | Definition | ChEBI: A nitrile that is acrylonitrile in which the hydrogen located beta,trans to the cyano group is replaced by a tosyl group. It is an inhibitor of cytokine-induced IkappaB-alpha phosphorylation i
cells. | | General Description | Potential anti-inflammatory agent that selectively and irreversibly inhibits the TNF-α-inducible phosphorylation of IκBα (IC50 = 10 μM), resulting in a decreased expression of NF-κB and of adhesion molecules. Does not affect constitutive IκBα autophosphorylation. Inhibits TNF-α-induced surface expression of the endothelial-leukocyte cell adhesion molecules E-selectin, VCAM-1, and ICAM-1. A 100 mM (10 mg/483 μl) solution of BAY 11-7082 (Cat. No. 196871) in DMSO is also available is also available. | | Biological Activity | Irreversible inhibitor of TNF- α -stimulated I κ B α phosphorylation (IC 50 ~ 10 μ M); leads to decreased NF- κ B and subsequent decreased expression of adhesion molecules. Also reversibly activates MAP kinases and stimulates apoptosis. | | Biochem/physiol Actions | Bay 11-7082 acts as a selective inhibitor for nod-like receptor family pyrin domain containing 3 (NLRP3) inflammasome pathway. In addition, to the inhibition of nuclear factor-kappa B (NF-kB), Bay 11-7082 also triggers apoptosis in anucleated erythrocytes, human T-cell leukemia virus type I (HTLV-I)-infected T-cell lines and primary adult T-cell leukemia cells. | | Enzyme inhibitor | This protein kinase inhibitor (FW = 207.31 g/mol; CAS 19542-67-7; lmax = 251 nm), also named 3-[(4-methylphenyl)sulfonyl]-(2E)-propenenitrile, targets NF-κB activation, selectively and irreversibly blocking TNF-α- induced phosphorylation of IκB-α without affecting phosphorylation of constitutive IκB-α. Mechanism of Inhibitory Action: NF-κB transcription factor regulates expression of inflammatory cytokines, various chemokines and immunoreceptors, as well as cell adhesion molecules. When stationed within the cytoplasm, NF-κB is kept inactive through its binding to the inhibitory factor IκB; however, certain stimuli result in IκB phosphorylation and ubiquitin-mediated degradation, freeing NF-κB for translocation to the nucleus. In endothelial cells, IκB-α phosphorylation and degradation occur within 15 min of TNFα treatment, allowing NF-κB to translocate to the nucleus to activate gene expression. Treatment of humnan vascular endothelial cells (HUVEC) with TNFα results in rapid loss of IκB-α from the cytoplasm. BAY11-7082 stabilizes IκB-α in a dose-dependent manner (IC50 ≈ 10 μM). There is a clear correlation between the concentration of drug that stabilizes IκB-α, the concentration that inhibits nuclear levels of NF-κB, and the concentration that inhibits adhesion molecule expression. More recent studies demonstrate that BAY 11- 7082 prevents ubiquitin conjugation to Ubc13 and UbcH7 by forming a covalent adduct with their cysteine residues via Michael addition at the C-3 atom of BAY 11-7082, followed by the release of 4-methylbenzenesulfinate. BAY 11-7082 stimulated Lys48-linked polyubiquitin chain formation in cells and protected Hypoxia-Inducible Factor-1α (HIF1α) from proteasomal degradation, suggesting it inhibits the proteasome. These results indicate that the anti-inflammatory effects of BAY 11-7082, its ability to induce B-cell lymphoma and leukemic T-cell death and to prevent the recruitment of proteins to sites of DNA damage are exerted via inhibition of components of the ubiquitin system– not by inhibiting NF-κB. BAY11-7082 also inhibits proliferation and promotes apoptosis in breast carcinoma MCF-7 cells by inhibiting phosphorylation of ATP citrate lyase. | | storage | +4°C | | Background | BAY 11-7082 is a selective and irreversible inhibitor of cytokine-induced IκBα phosphorylation. Treatment with TNF-α leads to the activation of IκBα resulting in nuclear translocation of NF-κB where it regulates gene expression. Inhibition of IκBα phosphorylation leads to the inactivation of NF-κB. The effect that BAY 11-7082 has on proinflammatory cytokine production as it relates to the NF-κB/IκB kinase pathways makes it useful when studying inflammation. This compound inhibits IFN-α production and nuclear translocation of interferon regulatory factor 7 in human plasmacytoid dendritic cells, both important factors when studying immunotherapeutic strategies as they relate to autoimmune disorders. BAY 11-7082 inhibits TNF-α-induced surface expression of ICAM-1, VCAM-1, and E-Selectin in human endothelial cells with an IC50 value between 5–10 μM. | | References | [1] J W PIERCE.
