Disruption in ER function and chronic ER stress are associated with pathologies that range from diabetes and neurodegenerative diseases to cancer and inflammation. Here, Fu et al. designed two high-throughput assays that test distinct endoplasmic reticulum (ER) functions, ER protein folding and ER chaperone capacity. With these assays, they identified a candidate compound, azoramide, that exhibits antidiabetic activity in mouse models of obesity and exhibited improved ER protein folding and increased ER chaperone capacity in their assays.
