4μ8C (IRE1 Inhibitor III)(IC50=76 nM) is an effective and specific IRE1 Rnase inhibitor.

IXA4 is a highly selective, nontoxic activator of IRE1/XBP1s and reduces APP secretion by activating IRE1. IXA4-stimulated IRE1 activation also enhanced pancreatic function.

Toyocamycin (Vengicide) is an adenosine analog produced by Actinomycetes, functioning as an XBP1 inhibitor and inhibiting IRE1α-induced ATP-dependent XBP1 mRNA cleavage (IC50: 80 nM), and induces apoptosis.

B I09, an IRE-1 RNase inhibitor with an IC50 of 1230 nM, inhibits splicing of XBP1 mRNA in human WaC3 cells and expression of xbp-1 in LPS-stimulated B cells. B I09 can be used to simulate the defects of XBP-1 in CLL cells., an IRE-1 RNase inhibitor with an IC50 of 1230 nM, inhibits splicing of XBP1 mRNA in human WaC3 cells and expression of xbp-1 in LPS-stimulated B cells. B I09 can be used to simulate the defects of XBP-1 in CLL cells., an IRE-1 RNase inhibitor with an IC50 of 1230 nM, inhibits splicing of XBP1 mRNA in human WaC3 cells and expression of xbp-1 in LPS-stimulated B cells. B I09 can be used to simulate the defects of XBP-1 in CLL cells.

GSK2850163 (S enantiomer) is the inactive enantiomer of GSK2850163. GSK2850163 is an novel inhibitor of inositol-requiring enzyme-1 alpha (IRE1a).

APY29 is an allosteric modulator of IRE1α; inhibits IRE1α autophosphorylation (IC50 = 280 nM) and activates IRE1α RNase activity.

D-F07 is a novel fluorescent IRE-1 RNase inhibitor and a tricyclic chromone with potential anticancer activity.

GSK2850163 is a novel inhibitor of inositol-requiring enzyme-1 alpha (IRE1α), effectively inhibiting both its RNase activity and IRE1α kinase activity (IC50s: 200 and 20 nM).
