Urea, N-[4-[8-aMino-3-(1-Methylethyl)iMidazo[1,5-a]pyrazin-1-yl]-1-naphthalenyl]-N'-[3-(trifluoroMethyl)phenyl]-

IRE1α kinase-IN-2 is a potent IRE1α kinase inhibitor, with an EC50 of 0.82 μM. IRE1α kinase-IN-2 inhibits IRE1α kinase autophosphorylation (IC50=3.12 μM). IRE1α kinase-IN-2 inhibits XBP1 mRNA splicing in the WT cell lines[1].
