Description: M77976 is a PDK4 inhibitor (human pyruvate dehydrogenase kinase 4). M77976 binds to the ATP-binding pocket of PDK4 and causes local conformational changes with complete disordering of the ATP lid. M77976 binding also leads to a large domain rearrangement that further expands the active-site cleft of PDK4 compared with the ADP- and AMPPNP-bound forms. Biochemical analyses revealed that M77976 inhibits PDK4 with increased potency compared with the previously characterized PDK inhibitor radicicol.
