Monoamine oxidase (MAO) subtypes, their substrates and inhibitors and cellular localization.
MAO-A | MAO-B | |
---|---|---|
Selective inhibitors (irreversible, covalent combination with enzyme active site) | Clorgyline | Selegiline (deprenyl), rasagiline |
Selective inhibitors (reversible, competitive inhibition) | Moclobemide | Lazabemide |
Non-selective inhibitors | Phenelzine, tranylcypromine | |
Selective substrates | 5-HT, noradrenaline, adrenaline | β-phenylethylamine, benzylamine |
Mixed substrates | Dopamine, tyramine | |
Cellular localization | Sympathetic neurons, noradrenergic, dopaminergic and other neurons in CNS, placenta, GI tract, hepatocytes and many other cell types | Astrocytes, platelets, many other peripheral cell types, serotonergic neuronal cell bodies in raphe nuclei |
