描述 | Pyruvate dehydrogenase kinase PDK1 is a metabolic enzyme responsible for switching glucose metabolism from mitochondrial oxidation to aerobic glycolysis in cancer cells, a general hallmark of malignancy termed the Warburg effect. JX06 is a potent, selective and covalent inhibitor of PDK with IC50s of 49, 101 and 313 nM for PDK1, PDK2 and PDK3, respectively. In A549 cells, JX06 (0-0.6 μM; 72 hours) dose-dependently inhibited the cell growth, and JX06 (0.1-10 μM; 6-24 hours) inhibited PDHA1 phosphorylation in a time- and dose-dependent manner. JX06 (1-10 μM) increased glucose uptake and intracellular ATP level and reduced aerobic glycolysis determined by the lactate production. JX06 (1-10 μM; 24 hours) induced ROS generation in cancer cells with high extracellular acidification rate (ECAR)/ oxygen consumption rate (OCR). In A549 xenograft models, JX06 (40-80 mg/kg; i.p. for 21 days) inhibited tumor growth[2]. | ||
作用机制 | JX06 forms a disulfide bond with the thiol group of a conserved cysteine residue (C240) based on recognition of a hydrophobic pocket adjacent to the ATP pocket of the PDK1 enzyme[2]. |
