 Carboxyatractyloside potassium salt has been used as an activator of Ca2+-induced mPTP (1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine) opening. It has also been used as a adenine nucleotide translocator (ANT) inhibitor to study the inhibition of oxidative phosphorylation in intact T98G glioma cells.  |  [Biochem/physiol Actions]
  Carboxyatractyloside is a highly selective inhibitor of cytosolic side-specific mitochondrial ADP/ATP carrier; i.e. adenine nucleotide translocase (ANT); causes stabilization of the c conformation of ANT leading to permeability transition pore (PTP) opening, loss of mitochondrial membrane potential, and apoptosis. |  [target]
