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

7-Hydroxy-4-methyl-2-oxo-2H-chromene-8-carbaldehyde is an activated molecule that exhibits significant cytotoxicity to human liver cancer cells. It inhibits the mitochondrial membrane potential, leading to the release of cytochrome c and apoptosis induction. 7HMOCA has been shown to be a reactive molecule with benzimidazole derivative properties. This compound depletes cellular glutathione levels and increases intracellular reactive oxygen species (ROS) levels, which leads to DNA fragmentation, cell cycle arrest, and ultimately apoptosis induction when combined with other agents. The fluorescence properties of this molecule have enabled its detection in living cells without the need for additional reagents or labeling.

Applications 8-Formyl-4-methylumbelliferone is an inhibitor that blocks substrate access to the active site of IRE1 and selectively inactivates both Xbp1 splicing and IRE1-mediated mRNA degradation. References Cross, B.C.S., et. al.: Proc. Natl. Acad. Sci. USA, 109, E869 (2012)
