PF-07247685 is a BCKDC kinase (BDK) inhibitor (EC50=2.2 nM). PF-07247685 stabilizes the interaction between BDK and BCKDH core subunit E2 and prevents phosphorylation of E1. While BDK mediates branched-chain ketoacid dedrogenase (BCKDH) phosphorylation, and inhibition of BCKDH is involved in controlling the rate-limiting step of branched-chain amino acid (BCAA) degradation. Impaired BCAA catabolism has been associated with several diseases, particularly cardiometabolic diseases, including heart failure (HF), type 2 diabetes mellitus (T2DM), non-alcoholic fatty liver disease (NAFLD), and obesity. PF-07247685 improved cardiometabolic endpoints and improves glucose tolerance in mice[1].
