Identification
Common Name3-Methoxytyrosine
ClassSmall Molecule
Description3-Methoxytyrosine is one of the main biochemical markers for Aromatic L-amino acid decarboxylase (AADC, EC 4.1.1.28) deficiency, an inborn error of metabolism that affects serotonin and dopamine biosynthesis. Patients are usually detected in infancy due to developmental delay, hypotonia, and extrapyramidal movements. Diagnosis is based on an abnormal neurotransmitter metabolite profile in CSF and reduced AADC activity in plasma. 3-methoxytyrosine is elevated in CSF, plasma, and urine. (1, 2, 3).

Toxicity Profile
Route of ExposureNot Available
Mechanism of ToxicityMethoxytyrosine is one of the main biochemical markers for aromatic L-amino acid decarboxylase deficiency, an inborn error of metabolism that affects serotonin and dopamine biosynthesis. 3-Methoxytyrosine is elevated in CSF, plasma, and urine. Catechol-O-methyl transferase is the enzyme in charge of 3-methoxytyrosine formation, which is produced from L-DOPA in many organs. Nevertheless, its half-life (15 hours approximately) is longer than the L-DOPA 's half-life, which is about one hour. This means that it is accumulated in the plasma and the brain of chronic L-DOPA therapy patients such as people suffering from Parkinson's disease. 3-Methoxytyrosine has some effects on L-DOPA related motor dysfunction, inhibition of striatal uptake of tyrosine, competition with L-DOPA for the blood–brain barrier transporter system and inhibition of dopamine release. 3-Methoxytyrosine increases homocysteine levels, and this amino acid induces cardiovascular disease and neuronal damage. Some other toxic effects could be oxidative DNA damage which can cause cell death, a decrease in locomotor activities and diminishment in mitochondrial membrane potential. (Wikipedia)
