Application

6,8-Bis(benzylthio)-octanoic acid has been used as pyruvate dehydrogenase (PDH) inhibitor:
  • to study its effects on neurite outgrowth in primary mouse dorsal root ganglia cells[1]
  • to induce α-smooth muscle actin (αSMA) and pro-collagen I expression and to assess PDH enzyme activity in whole-cell lysates[2]
  • to validate basal respiration in tissue respirometry[3]

Biochem/physiol Actions

6,8-Bis(benzylthio)-octanoic acid (CPI-613) is a lipoate analog. It acts as a mitochondrial disrupter by blocking the mitochondrial enzymes pyruvate dehydrogenase and α-ketoglutarate dehydrogenase.[4]
6,8-Bis(benzylthio)-octanoic acid is an E1α pyruvate dehydrogenase (PDH) modulator that prevents cancer cells from metabolizing glucose for energy. 6,8-Bis(benzylthio)-octanoic acid has been granted orphan drug status by the US FDA for pancreatic cancer.
