Bay11-7082 NLRP3 Inflammasome Inhibitor - IκB-α Inhibitor Bay 11-7082 is an irreversible inhibitor of TNF-α-induced IκB-α phosphorylation resulting in the inactivation of NF-κB [1]. TNF-α-dependent effects of NF-κB are important for TLR expression and cytokine production [2,3]. Moreover Bay11-7082 selectively inhibit NLRP3 inflammasome activity in macrophages independent of their inhibitory effect on NF-κB activity [4].
