Application

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

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.
Bay 11-7082 is an inhibitor of cytokine-induced IκB-α phosphorylation.
