Inhibition of human RIP1 (1 to 375 residues) expressed in baculovirus infected insect cells preincubated for 1 hr followed by ATP addition measured after 5 hrs by ADP-Glo luminescence assay, IC50 = 0.001 μM.
Inhibition of RIP1 in human U937 cells assessed as reduction in TNFalpha/QVD-Oph-induced necrosis after 24 hrs by Cell Titer-Glo luminescent cell viability assay, IC50 = 0.0063 μM.
Inhibition of RIP1 in mouse L929 cells assessed as reduction in TNFalpha/QVD-Oph-induced necrosis after 24 hrs by Cell Titer-Glo luminescent cell viability assay, IC50 = 1.3 μM.
