4µ8C is an inhibitor of inositol requiring enzyme 1 α (IRE1α), which is a protein located in the endoplasmic reticulum (ER) membrane that has kinase and RNase activities triggered by ER stress.{39181} 4µ8C inhibits IRE1α 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 IRE1α autophosphorylation. It reduces IL-4 production in CD4+ T cells isolated from murine spleen and LPS-stimulated increases in TNF-α and IL-6 mRNA expression and protein secretion in isolated alveolar macrophages from patients with cystic fibrosis.{39182,39183}

    The maintenance of embryonic stem cells in culture typically requires feeder cells and various exogenous factors found in serum. Murine embryonic stem (mES) cells can be maintained in the absence of feeder cells and serum but require the leukemia inhibitor factor (LIF) and bone morphogenic protein (BMP) to prevent differentiation and promote self-renewal.
