The gene variant has been shown to affect cognitive tasks broadly related to executive function inhibidodes, such as set shifting, response inhibition, abstract thought, and comh acquisition of rules or task structure. Available structures PDB Ortholog search: The O in the name stands for oxygennot for ortho.

COMT inhibition in the treatment of Parkinson’s disease.

The enzyme introduces a methyl group to the catecholamine, which is donated by S-adenosyl methionine SAM. In the brain, COMT-dependent dopamine degradation is of particular importance in brain regions with low expression of the presynaptic dopamine transporter DATsuch as the prefrontal cortex.

COMT inhibition in the treatment of Parkinson’s disease.

Retrieved from ” https: Tryptophan hydroxylase Aromatic L-amino acid decarboxylase Aralkylamine N-acetyltransferase Acetylserotonin O-methyltransferase. From Wikipedia, the free encyclopedia. Research conducted at the Section of Neurobiology of PsychosisInstitute of Psychiatry, King’s College London has demonstrated an effect of COMT both in patients with bipolar disorder and in their relatives, [36] [ unreliable medical source ] but these findings have not been replicated so far.

The American Journal of Psychiatry. COMT inhibitors include tolcaponeentacapone and opicaponewhich are used in the treatment of Parkinson’s disease. Please improve this by adding secondary or tertiary sources. Journal of Oral Rehabilitation. The Central Nervous System. Both entacapone and tolcapone are well-tolerated. Zhu BT October Journal of Neural Transmission. Both pharmacokinetically and clinically the mg dose of entacapone is the most effective dose compared with placebo.

Thus, COMT inhibitors are clinically significant and beneficial adjunct to levodopa therapy in Parkinson’s disease patients with end-of-dose fluctuations.

Serine hydroxymethyltransferase 3-methyloxobutanoate hydroxymethyltransferase. For tolcapone and mg have most often proved to be the optimal doses. Temporomandibular joint dysfunction TMD does not appear to be a classic genetic disorder, however variations in the gene that codes for COMT have been suggested to be responsible for inheritance of a predisposition to develop TMD ihibidores life.

The best-studied is ValMet.

Catechol- O -methyltransferase is involved in the inactivation of the catecholamine neurotransmitters dopamineepinephrineand norepinephrine. The British Journal of Psychiatry.


The dyskinesias are managed by decreasing the daily levodopa dose in Parkinson’s disease patients with end-of-dose fluctuations. Views Read Edit View history. However, tolcapone is clinically restricted owning to its increased hepatotoxicity and other related digestive disorders.

Betaine-homocysteine methyltransferase Homocysteine methyltransferase Methionine synthase. Genetic variation with functional impact on cortical dopamine tone has a strong influence on reward experience in the flow of daily life.

When given with an inhibitor of dopa decarboxylase carbidopa or benserazidelevodopa is optimally saved. Retrieved November 16, It is increasingly recognised that allelic variation at the COMT gene are also relevant for emotional processing, as they seem to influence the interaction between prefrontal and limbic regions.

Consequently, they increase the elimination half-life of levodopa and thus prolong the availability of levodopa to the brain without significantly affecting the Cmax or tmax of levodopa.
