Inhibition of AMP-Activated Protein Kinase at the Allosteric Drug-Binding Site Promotes Islet Insulin Release

The AMP-activated protein kinase (AMPK) is a metabolic stress-sensing αβγ heterotrimer responsible for energy homeostasis. Pharmacological inhibition of AMPK is regarded as a therapeutic strategy in some disease settings including obesity and cancer; however, the broadly used direct AMPK inhibitor compound C suffers from poor selectivity. We have discovered a dihydroxyquinoline drug (MT47-100) with novel AMPK regulatory properties, being …
