TRISODIUM 2-METHYLCITRATE, RACEMIC MIXTURE OF DIASTEREOMERS

2-Methylcitric acid trisodium impairs glutamate metabolism and induces permeability transition in brain mitochondria.
2-Methylcitric acid trisodium inhibits glutamate dehydrogenase (GDH) activity at concentrations as low as 0.5 mM.
2-Methylcitric acid trisodium (1 mM, 3 mM; 150 seconds) provokes a significant decrease in mitochondrial membrane potential and induced swelling in Ca ²⁺ -loaded mitochondria supported by different substrates.
2-Methylcitric acid trisodium behaves as a potent inhibitor of glutamate oxidation by inhibiting glutamate dehydrogenase activity and as a permeability transition inducer, disturbing mitochondrial energy homeostasis.
2-Methylcitric acid trisodium does not significantly impair mitochondrial glutamate transport.
2-Methylcitric acid trisodium does not significantly impair glutamate mitochondrial transport in liver mitochondria.
