Beschreibung

Anwendung

α-Methyl-L-tyrosine has been used as an inhibitor tyrosine hydroxylase:

• to test its effect during acute stress in zebrafish
• in cannabinoid receptor type-1 (CB1) knockout and wild type mice, to test its effect on norepinephrine turnover
• to test catecholamines depletion on stress in rat spleen samples
• to block dopamine synthesis in dopaminergic neurons

α-Methyl-L-tyrosine is used to determine whether Fe²/ methamphetamine (METH) -induced cell death is dependent on cytosolic dopamine and iron mediated oxidative stress.

Biochem./physiol. Wirkung

α-Methyl-L-tyrosine (L-AMPT) acts as a competitive inhibitor of tyrosine hydroxylase and inhibits the conversion of tyrosine to L-DOPA and eventually lowers dopamine synthesis in cytosol. AMPT at low concentrations can be used as a potent therapeutic for refractory dystonia or dyskinesia. It also helps in decreasing catecholamine concentration in pheochromocytoma patients.
