TNF-α Antagonist III, R-7050

TNF-α Antagonist III, R-7050 is a cell-permeable triazoloquinoxaline compound that is reported to act as a TNF-α receptor antagonist via the blockage of receptor-adaptor molecules complex formation and subsequent receptor internalization, but not TNF-α ligand-receptor binding. Additionally it has been shown to selectively inhibit TNF-α-, but not Fas- or C6-ceramide-, induced caspase activation and cell death in ME180 cells and exhibit higher potency against TNF-α-induced than IL-1β-induced NF-κB activation (EC₅₀ = 0.631 and 1.45 µM, respectively) in A549 cells.
