2-甲基柠檬酸

2-Methylcitric acid (Methylcitric acid) impairs glutamate metabolism and induces permeability transition in brain mitochondria. 2-Methylcitric acid inhibits glutamate dehydrogenase (GDH) activity at concentrations as low as 0.5 mM.
2-Methylcitric acid (1-3 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 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 does not significantly impair mitochondrial glutamate transport. 2-Methylcitric acid does not significantly impair glutamate mitochondrial transport in liver mitochondria.
