Description

IRE-3 is a highly potent and selective small molecule modulator of IRE1α. Under endoplasmic reticulum stress, unfolded protein accumulation leads to activation of the endoplasmic reticulum transmembrane kinase/endoRNase (RNase) IRE1α. IRE1α oligomerizes, autophosphorylates and initiates splicing of XBP1 mRNA, thus triggering the unfolded protein response (UPR). Interestingly, IRE-3 inhibits the XBP1 mRNA splicing through binding to the IRE1α ATP-binding site, even under endoplasmic reticulum stress. It shows dose-dependent reduction of IRE1α kinase autophosphorylation in vitro with IC50~3.12 µM. IRE-3 can also block enzymatic activities of IRE1α in INS-1 rat insulinoma cell lines. As dysregulation of the UPR has been implicated in a variety of cell degenerative and neoplastic disorders, small molecule modulators of IRE1α, such as IRE-3 and APY-29, serve as useful tools to understand the UPR's role in pathophysiology and to develop drugs for endoplasmic reticulum stress-related diseases.
