生物活性

BAY 11-7082 is an IκBα phosphorylation and NF-κB inhibitor. BAY 11-7082 selectively and irreversibly inhibits the TNF-α-induced phosphorylation of IκB-α, and decreases NF-κB and expression of adhesion molecules. BAY 11-7082 inhibits ubiquitin-specific protease USP7 and USP21 (IC50=0.19, 0.96 μM, respectively). BAY 11-7082 inhibits gasdermin D (GSDMD) pore formation in liposomes and inflammasome-mediated pyroptosis and IL-1β secretion in human and mouse cells.

体外研究

BAY 11-7082 (BAY 11-7821), an inhibitor of NF-κB, induces apoptosis of HTLV-I-infected T-cell lines but only negligible apoptosis of HTLV-I-negative T cells. Bay 11-7082 rapidly and efficiently reduces the DNA binding of NF-κB in HTLV-I-infected T-cell lines and down-regulated the expression of the antiapoptotic gene, Bcl-xL, regulated by NF-κB. Bay 11-7082 selectively inhibits Tax-induced NF-κB activity in a human T-cell line. BAY 11-7082 inhibits NFκB signalling and is recently shown to inhibit the majority of E2 and E3 ligases tested by reacting covalently with the catalytic cysteine residues. Moreover, BAY 11-7082 also inhibits several tyrosine phosphatases by reacting with catalytic Cys residue of these enzymes. NSC 697923 is originally shown to inhibit the E2 ligase Ubc13-Uev1A. BAY 11-7082 inhibits the phosphorylation of IκBα and activation of NF-κB, induces the death of HBL-1 cells. BAY 11-7082 completely suppresses the LPS-stimulated and IL-1-stimulated phosphorylation of the activation loop of IKKβ. BAY 11-7082 acts by inhibiting TNF-α-induced phosphorylation of IκB-α, resulting in decreased NF-κB and decreases expression of adhesion molecules.
