Overview

  • Product name
    4μ8C
  • Description
    Potent, selective IRE1 Rnase inhibitor
  • Alternative names
    • 4-methyl umbelliferone 8-carbaldehyde
    • 7-Hydroxy-4-methyl-2-oxo-2H-1-benzopyran-8-carboxaldehyde
    • 8-formyl-7-hydroxy-4-methylcoumarin
  • Biological description

    Blocks substrate access to the active site of IRE1α. Inhibits regulated IRE1-dependent degradation (RIDD) and unconventional spicing of Xbp1 mRNA in response to endopasmic reticulum (ER) stress but has no effect on IRE1 kinase activity.

  • Handling

    Wherever possible, you should prepare and use solutions on the same day. However, if you need to make up stock solutions in advance, we recommend that you store the solution as aliquots in tightly sealed vials at -20°C. Generally, these will be useable for up to one month. Before use, and prior to opening the vial we recommend that you allow your product to equilibrate to room temperature for at least 1 hour.
