BromantanevsNALT

Bromantane upregulates tyrosine hydroxylase (TH)—the rate-limiting enzyme in catecholamine synthesis—and aromatic L-amino acid decarboxylase (AADC), the enzymes responsible for converting L-tyrosine to L-DOPA and then to dopamine. This increases neuronal dopamine production capacity rather than depleting vesicular stores like traditional stimulants. The mechanism may involve modulation of transcription factors or enzyme phosphorylation. Bromantane also has anxiolytic properties through enhancement of GABAergic transmission, possibly via GABA-A receptor modulation or increased GABA synthesis. The combination of upregulated dopamine synthesis in mesolimbic and nigrostriatal pathways with GABAergic dampening of anxiety circuits produces sustained motivation, focus, and reduced mental fatigue without the jitteriness or crash typical of dopamine-releasing agents.

NALT (N-acetyl L-tyrosine) is deacetylated by aryl acylamidase in the gut and liver to release L-Tyrosine. Tyrosine is hydroxylated to L-DOPA by tyrosine hydroxylase (TH) — the rate-limiting step in catecholamine synthesis, requiring tetrahydrobiopterin as cofactor. L-DOPA is decarboxylated by aromatic L-amino acid decarboxylase (AADC) to dopamine; dopamine is converted to norepinephrine by dopamine beta-hydroxylase (DBH), and norepinephrine to epinephrine by phenylethanolamine N-methyltransferase (PNMT). Under stress or sleep deprivation, catecholamine stores in noradrenergic and dopaminergic neurons deplete rapidly. Supplemental tyrosine provides substrate to maintain synthesis when demand exceeds supply, supporting prefrontal cortex function and working memory.
