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 (1). 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 (2). This compound inhibits IFN-α production and nuclear translocation of interferon regulatory factor 7 (IRF7) in human plasmacytoid dendritic cells, both important factors when studying immunotherapeutic strategies as they relate to autoimmune disorders (3). 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 (1).
