Biological Activity for Bay 11-7821

Bay 11-7821 is an E2 ubiquitin (Ub) conjugating enzyme inhibitor. Inhibits the conjugation of Ub to a range of E2 enzymes. Inhibits E2 enzyme mediated IκBα phosphorylation and indirectly decreases NF-κb activity. Also reversibly activates MAPK signaling. Induces apoptosis of leukemic T cell and B-cell lymphoma cell lines. Also inhibits activation of NLRP3 inflammasome. Binds and inhibits gasdermin D (GSDMD) pore formation. Pyroptosis inhibitor.
