卡哥鲁酸 (Carbaglu, Ucedane)

概览

Carglumic acid is an analog of N-acetylglutamate (NAG) used for the treatment of acute and chronic hyperammonemia in patients with N-acetylglutamate synthase (NAGS) deficiency.

作用机制

Carglumic acid is a synthetic structural analogue of N-acetylglutamate (NAG), which is an essential allosteric activator of the liver enzyme carbamoyl phosphate synthetase 1 (CPS1). CPS1 is found in the mitochondria and is the first enzyme of the urea cycle, which converts ammonia into urea. Carglumic acid acts as a replacement for NAG in NAGS deficiency patients by activating CPS1 but it does not help to regulate the urea cycle.

适应症

For the treatment of acute and chronic hyperammonaemia in patients with N-acetylglutamate synthase (NAGS) deficiency. This enzyme is an important component of the urea cycle to prevent build up of neurotoxic ammonium in the blood.

• Acute Hyperammonaemia
• Chronic Hyperammonaemia
