Bay 11-7821(Bay 11-7082) is an inhibitor of IKK with IC50 value of 10μM [1].

Bay 11-7821 inhibits the TNFα-induced phosphorylation of IκB-α, results in an inhibition of NF-κB. This subsequently causes the inhibition of the TNFα-induced surface expression of E-selectin, VCAM-1, and ICAM-1. It is reported that, Bay 11-7821 does not inhibit entire TNFα-induced phosphorylation but selectively inhibits phosphorylation of IκB-α [1].

Experiments show that Bay 11-7821 is highly toxic at concentrations of effective IKK inhibition. It can induce cell necrosis in MM cells. Additionally, Bay 11-7821 is proved to have an anti-inflammatory ability via inducing death of B-cell lymphoma and leukaemic T-cell. It is also reported to inhibit the NALP3 inflammasome in macrophages [2, 3].
