PF-07238025

PF-07238025, a potent branched-chain ketoacid dehydrogenase kinase (BDK) inhibitor with an EC50 of 19 nM, enhances the stability of the BDK-BCKDH core E2 subunit interaction and inhibits the phosphorylation of the E1 subunit. By modulating BDK, which regulates the phosphorylation of BCKDH, a key enzyme in branched-chain amino acid (BCAA) degradation, PF-07238025 indirectly controls the rate-limiting step in BCAA catabolism. Dysregulated BCAA metabolism is implicated in various cardiometabolic disorders such as heart failure (HF), type 2 diabetes mellitus (T2DM), non-alcoholic fatty liver disease (NAFLD), and obesity. Notably, PF-07238025 has been shown to ameliorate cardiometabolic endpoints and enhance glucose tolerance in mouse models [1].
