IW927

IW927 is a photochemically enhanced TNF-α-TNFR1 interaction inhibitor that blocks the binding of TNF-α to TNFRc1 with an IC50 value of 50 nM. IW927 binds reversibly to the TNFRc1 with weak affinity (Kd = 40-100 μM), covalently modifies the receptor via a photochemical reaction, and does not bind the related cytokine receptors TNFRc2 or CD40. IW927 disrupts TNFα-induced IκB phosphorylation with an IC50 value of 600 nM. IW927 can be used to develop light-independent inhibitors[1].
