|Overview||A cell-permeable, bioavailable, non-toxic, imidazopyrazinyl-naphthalenyl-phenylurea based compound that acts as a potent, ATP-competitive, reversible, and selective inhibitor of IRE1α kinase (IC50 = 600 nM). Exhibits good selectivity over ERK2, JNK2, JNK3, PIM1, PAK4, and PKA (IC50 > 10 µM). Stabilizes the kinase domain of IRE1α in an inactive conformation and blocks its oligomerization and thereby reduces RNase domain activity. Shown to block brefeldin A-(Cat. Nos. 203729 & 500583) induced ER stress and apoptosis in INS-1 cells and tunicamycin (Cat. Nos. 654380 & 504570)-induced apoptosis in β-cells derived from C57BL/6 mice. Affords significant cytoprotection in combination with STF-083010 (Cat. No. 412510, 1 µM) and KIRA6 (50 nM). Systemic administration of KIRA6 in the Akita diabetic mice is shown to reduce their blood glucose levels, improve glucose tolerance, and conserve their β-cell function. Preserves photoreceptor function in a transgenic rat model (P23H) of chronic ER stress-induced retinal degeneration, when administered intravitreally. Displays desirable pharmacokinetic properties with t1/2 = 3.9 h and moderate clearance rate of 22.4 ml/min/kg in BABL/c mice (10 mg/kg, i.p.).
Please note that the molecular weight for this compound is batch-specific due to variable water content.
