AMPT prevents the conversion of tyrosine to L-DOPA, the precursor to dopamine; reserpine prevents dopamine storage within vesicles; and deprenyl inhibits monoamine oxidase (MAO)-B and thus increases dopamine levels.
O AMPT impide a conversión de tirosina en L-DOPA, o precursor da dopamina; a reserpina impide o almacenamento de dopamina nas vesículas sinápticas; e o deprenilo inhibe a monoamino oxidase B (MAO-B) e dese modo incrementa os niveis de dopamina.
