Inhibition of thapsigargin-induced autophosphorylation of PERK in human A549 cells preincubated for 1 hr followed by thapsigargin-induction measured after 1 hr by Western blotting analysis, IC50<0.03μM.
Anti-neprotic activity in mouse MEF cells assessed as reduction in TNF-induced necroptosis and measured every 1 hr in presence of z-VAD by SYTOX Green dye based fluorescence assay, IC50=0.0073μM.
Anti-neprotic activity in mouse L929 cells assessed as reduction in TNF-induced necroptosis and measured every 1 hr by SYTOX Green dye based fluorescence assay, IC50=0.0004μM.
