The dysregulation of the inositol-requiring enzyme 1 alpha (IRE1α) has been associated with multiple human diseases, so IRE1α-targeting small molecules present great therapeutic potential. Here, the authors report a series of substituted indoles as IRE1α inhibitors of good potency and selectivity, and show that the inhibitor IA107 allosterically inhibits IRE1α RNase activity via binding to the IRE1α kinase domain but without inhibiting the IRE1α dimerization.
