Introduction of 389142-48-7 :

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]. In Vitro:IW927 (1 μM in the light or 100 μM in the dark, 5 min) exhibits significant light dependence, forming irreversible covalent binding to TNFRc1 only under light conditions and only reversible binding under light-protected conditions[1].
IW927 (24 h) does not display any cytotoxicity at concentrations as high as 100 μM in Ramos cells[1].
