|Overview||A cell-permeable chlorophenylpropionate compound that is superior to its structural analog 4PB (Cat. No. 567616) as an inhibitor against mitochondrial branched-chain α-ketoacid dehydrogenase complex (BCKDC) regulatory kinase BDK (BCKD kinase; IC50 = 6.3 vs. 53.1 µM) due to much optimized affinity toward the BDK N-terminal allosteric site (Kd = 2.4 vs. 5.7 µM), effectively blocking BDK substrate access by preventing BDK interaction with the homo-24-meric dihydrolipoyltransferase BCKDC E2 component, while exhibiting little potency against PDK2 or BCKD phosphatase BDP even at concentrations as high as 1 mM (<10% inhibition). Shown to effectively reduce E1-α Ser293 phosphorylation with concomitant BCKDC activity upregulation in multiple tissues in mice (EDmax =160 mg/kg via i.p.) in vivo. Despite good stability and low in vivo clearance , high doses are recommended for mice treatment due to low tissue penetration efficiency.|
