Alpha-1A adrenergic receptor Amine oxidase [flavin- containing] A Beta-1 adrenergic receptor Beta-2 adrenergic receptor Synaptic vesicular amine transporter Sodium- dependent noradrenaline transporter Synaptic vesicular amine transporter Sodium- dependent noradrenaline transporter Aromatic-L- amino-acid decarboxylase Dopamine beta- hydroxylase Tyrosine 3-monooxygenase Aldehyde dehydrogenase, dimeric NADP-preferring Catechol O- methyltransferase Norepinephrine Tranylcypromine Norepinephrine Norepinephrine Norepinephrine Tranylcypromine Tranylcypromine Tranylcypromine L-Dopa Dopamine CO2 Ascorbic acid O2 Dehydroascorbic acid H2O H2O O2 3,4-Dihydroxymandelaldehyde H2O2 NH3 L-Tyrosine Tetrahydrobiopterin O2 Dihydrobiopterin H2O NAD H2O 3,4-Dihydroxymandelic acid NADH H+ S-Adenosylmethionine Vanillylmandelic acid S-Adenosylhomocysteine Magnesium Gq signaling cascade Gs signaling cascade FAD Pyridoxal 5'-phosphate Fe2+ Pyrroloquinoline quinone Copper Post synaptic neuron Norepinephrine is synthesized from tyrosine and stored in presynaptic vesicles. Synapse Cytosol Presynaptic Neuron Cytosol Postsynaptic Neuron Diffusion Blood-Brain Barrier Tranylcypromine is transported in the neurons by the noradenaline reuptake transporter. Tranylcypromine inhibits the amine oxidase A and B. This results in the decrease of the metabolism of norepinephrine. The inhibition of this enzyme will increase the concentration in norepinephrine in the cytosol of the presynaptic neuron. Since depression is caused by low level of free serotonin and/or norepinephrine, the increasing in free norepinephrine results in the relief of depressive symptoms. Mood Improvement Norepinephrine activates post synaptic adrenergic receptors which are responsible for mood improvements.
