Description

Application

STF-083010 has been used:

• in a study to investigate the potential anti-lipotoxic effect of nicotinamide and to elucidate underlying mechanism(s)
• as IRE1a inhibitor to study its effect on NOS 2 expression and investigate the underlying mechanisms in proinflammatory gene expression in astrocytes
• to block endogenous XBP1 cleavage for one hour prior to palmitate exposure in order to examine whether inositol?requiring enzyme 1α (IRE1α ) activation is implicated in palmitate cytotoxicity

Biochem/physiol Actions

STF-083010 is a potent inhibitor of the ER transmembrane protein IRE1, which mediates the unfolded protein response. STF-083010 inhibits IRE1 endonuclease and mRNA splicing activity in response to endopasmic reticulum (ER) stress, but has no affect on the kinase activity of IRE1.
