ire1α rnase 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).

3,6-DMAD dihydrochloride is an acridine derivative and a potent inhibitor of the IRE1α-XBP1s pathway. 3,6-DMAD dihydrochloride can induce IL-6 secretion by exploiting the IRE1α-XBP1s pathway. 3,6-DMAD dihydrochloride is a potent inhibitor of the IRE1α-XBP1s pathway. 3,6-DMAD dihydrochloride has inhibitory effects on IRE1α oligomerization and RNase activity. 3,6-DMAD dihydrochloride can be used in cancer research.

Kira8 Hydrochloride is a mono-selective IRE1α inhibitor that allosterically attenuates IRE1α RNase activity with an IC50 of 5.9 nM.

Kira8 (AMG-18) is a mono-selective IRE1α inhibitor that allosterically attenuates IRE1α RNase activity with an IC50 of 5.9 nM.

KIRA-7 is an imidazopyrazine compound. KIRA-7 has an anti-fibrotic effect. KIRA-7 binds the IRE1α kinase (IC50: 110 nM) to allosterically inhibit its RNase activity.

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

4μ8C (IRE1 Inhibitor III) is a highly selective and potent inhibitor of IRE1α ribonuclease (RNase) activity (IC₅₀ ≈ 6–10 μM). By forming a covalent bond with the RNase active site of IRE1α, 4μ8C specifically inhibits its ribonuclease activity, thereby blocking the splicing of XBP1 mRNA. 4μ8C can be used in research on endoplasmic reticulum stress, the unfolded protein response, immune regulation, and tumor and metabolic diseases.

IRE1α kinase-IN-1 is a highly selective IRE1α (ERN1) inhibitor, with an IC50 of 77 nM, displaying 100-fold selectivity over the IRE1β isoform. It inhibits ER stress-induced IRE1α oligomerization and autophosphorylation, as well as IRE1α RNase activity (IC50=80 nM).
