Biochem/physiol Actions

4μ8C is a salicylaldehyde derivative and its inhibitory action targets the K907 lysine residue in RNase (ribonuclease) domain and affects IRE1α (endoplasmic reticulum to nucleus signaling 1) RNase activity. In vitro analysis proved that 4μ8C was able to inhibit the release of insulin at high glucose levels.
4μ8C is a potent inhibitor of the ER transmembrane protein IRE1, which mediates the unfolded protein response. 4μ8C inhibits regulated IRE1-dependent degradation (RIDD) and unconventional spicing of XBP1 mRNA in response to endopasmic reticulum (ER) stress, but has no affect on the kinase activity of IRE1.
