Biochem/physiol Actions

KIRA8 is an ATP-competitive, potent and selective IRE1α kinase inhibitor (IRE1α/β Ki = 2/120 nM) that attenuates IRE1α endonuclease activity (IRE1α/β IC50 = 5/55 nM) with good kinome selectivity. KIRA8 inhibits thapsigargin-induced UPR (IC50 = 99 nM; HT1080 XBP1-Luc cells) and shows therapeutic efficacy in murine models of type 1 diabetes (T1D), pulmonary fibrosis, multiple myeloma (MM), and pancreatic neuroendocrine tumors (PanNET) in vivo (30-50 mg/kg/day i.p.).

In cells experiencing unrelieved endoplasmic reticulum (ER) stress, the ER transmembrane kinase/endoribonuclease (RNase)-IRE1α-endonucleolytically degrades ER-localized mRNAs to promote apoptosis. Here we find that the ABL family of tyrosine kinases rheostatically enhances IRE1α's enzymatic activities, thereby potentiating ER stress-induced apoptosis. During

The dual kinase endoribonuclease IRE1 is a master regulator of cell fate decisions in cells experiencing endoplasmic reticulum (ER) stress. In mammalian cells, there are two paralogs of IRE1: IRE1α and IRE1β. While IRE1α has been extensively studied, much less

Multiple myeloma (MM) arises from malignant immunoglobulin (Ig)-secreting plasma cells and remains an incurable, often lethal disease despite therapeutic advances. The unfolded-protein response sensor IRE1α supports protein secretion by deploying a kinase-endoribonuclease module to activate the transcription factor XBP1s. MM

Master regulators of the unfolded protein response (UPR), IRE1α and PERK, promote adaptation or apoptosis depending on the level of endoplasmic reticulum (ER) stress. Although the UPR is activated in many cancers, its effects on tumor growth remain unclear. Derived
