Description | IRE1α kinase-IN-1 is a highly selective IRE1α (ERN1) inhibitor, with an IC50 of 77 nM. It displays 100-fold selectivity for IRE1α over the IRE1β isoform. It inhibits ER stress-induced IRE1α oligomerization and autophosphorylation, and also inhibits IRE1α RNase activity (IC50=80 nM) |
In vitro | IRE1α kinase-IN-1 (compound 31) effectively mitigates endoplasmic reticulum stress by hindering IRE1α oligomerization and phosphorylation, while also suppressing its endoribonuclease activity within human cells[1]. Demonstrating exceptional specificity, this compound shows greater than 70% inhibition for only 4 out of 455 kinases tested, highlighting its select focus on IRE1α. It notably attenuates recombinant G547 IRE1α KEN domain pS274 autophosphorylation, achieving an IC50 of 160 nM, and disrupts ATP-site LanthaScreen tracer binding to the recombinant dephosphorylated G547 IRE1α KEN with an IC50 of 0.27 μM[1]. Additionally, it prevents tunicamycin-induced GFP-IRE1α foci formation in HEK293 cells with an IC50 value of 0.74 μM and obstructs both tunicamycin- and thapsigargin-induced IRE1α-dependent XBP1 mRNA splicing, with IC50 values ranging from 0.68 to 1.63 μM in the same cell line[1]. Moreover, in H929 and NCI-H929 cells, IRE1α kinase-IN-1 dose-dependently suppresses IRE1α-dependent XBP1s mRNA expression when applied at concentrations between 0 to 20 μM, demonstrating its potent inhibitory activity on tunicamycin-induced XBP1s expression[1]. |
