4µ8C is an inhibitor of inositol requiring enzyme 1 ? (IRE1?), which is a protein located in the endoplasmic reticulum (ER) membrane that has kinase and RNase activities triggered by ER stress.{39181} 4µ8C inhibits IRE1? splicing of Xbp1 mRNA (IC50 = 6.8 µM) and reduces subsequent gene expression of Erdj4 (IC50 = 3.4 µM) in stress-cultured MEF cells but does not block IRE1? autophosphorylation. It reduces IL-4 production in CD4+ T cells isolated from murine spleen and LPS-stimulated increases in TNF-? and IL-6 mRNA expression and protein secretion in isolated alveolar macrophages from patients with cystic fibrosis.{39182,39183}
