[16] [17] Whereas the latter directly act on the dopamine transporter (DAT) to inhibit the reuptake and/or induce the release of dopamine, bromantane instead acts via indirect genomic mechanisms to produce a rapid, pronounced, and long-lasting upregulation in a variety of brain regions of the expression of tyrosine hydroxylase (TH) and aromatic L-amino acid decarboxylase (AAAD) (also known as DOPA decarboxylase), key enzymes in the dopamine biosynthesis pathway
