Applicazioni
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.
Azioni biochim/fisiol
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.
Tyrosine hydroxylase inhibitor.

In this article, we show that the tyrosine hydroxylase inhibitor α-Methyl-l-tyrosine (AMPT) decreased the responsiveness of the zebrafish stress axis to an acute stressful challenge. These effects were specific for responses to stimulation, since unstimulated (basal) cortisol levels were not
