SPD-304

Tumor necrosis factor alpha (TNF-alpha) is a primary mediator of many inflammatory conditions including rheumatoid arthritis, toxic shock, and sepsis. TNF-alpha functions as a trimer and promotes receptor trimerization to activate proinflammatory and/or apoptotic signalling pathways. SPD-304 is an inhibitor of tumor necrosis factor alpha (TNF-alpha). that prevents binding to the TNF Receptor 1 (TNFR1) with an IC50 of 22 µM. It binds to the biologically active TNF-alpha trimer and promotes accelerated displacement of a single subunit to rapidly inactivate the cytokine. In a cell based assay, SPD-304 inhibited TNFalpha-mediated stimulation of IKB degradation with an IC50 of 4.6 µM.Formal Name: 6,7-dimethyl-3-[[methyl[2-[methyl[[1-[3-(trifluoromethyl)phenyl]-1H-indol-3-yl]methyl]amino]ethyl]amino]methyl]-4H-1-benzopyran-4-one.
