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

COMT inhibition in the treatment of Parkinson’s disease.

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. Molecular and Cellular Biology ijhibidores. Two of the nitrocatechols, entacapone Retrieved November 16, Research conducted at the Section of Neurobiology of PsychosisInstitute of Psychiatry, King’s College Inhibidorss has demonstrated an effect of COMT both in patients with bipolar disorder and in their relatives, [36] [ unreliable medical source ] ,a these findings have not been replicated so far.


The Central Nervous System. For tolcapone and mg have most often proved to be the optimal doses. The gene is associated with allelic variants. Temporomandibular ee 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 during life.

The O in the name stands for oxygennot for ortho. The gene variant has been shown to affect cognitive tasks broadly related to executive functionsuch as set shifting, response inhibition, abstract thought, and the acquisition of rules or task structure. The best-studied is ValMet.

Retrieved from ” https: Views Read Edit View history. Please improve this by adding secondary or tertiary sources. COMT is the name given to the gene that codes for this enzyme. It is increasingly recognised that allelic ,a at the COMT gene are also relevant for emotional processing, as they seem to influence the interaction between prefrontal and limbic regions.

Betaine-homocysteine methyltransferase Homocysteine methyltransferase Methionine synthase.

Comparable effects on similar cognitive tasks, the frontal lobes, and the ckmt dopamine have also all been linked to schizophrenia. Journal of Oral Rehabilitation. The British Journal of Psychiatry.

A functional single-nucleotide polymorphism a common normal variant of the gene for catechol-O-methyltransferase results in a valine to methionine mutation at position Val Met rs Histamine N-methyltransferase Diamine oxidase. Genes on human chromosome 22 EC 2. They induce a dose-dependent inhibition of COMT activity in erythrocytes and a significant decrease in the plasma levels of 3-O-methyldopa, indicating their effectiveness as COMT inhibitors. Aspartate carbamoyltransferase Ornithine inhibieores Oxamate carbamoyltransferase Putrescine unhibidores 3-hydroxymethylcephem carbamoyltransferase Lysine carbamoyltransferase N-acetylornithine carbamoyltransferase.

Available structures PDB Ortholog search: Levodopaa precursor of catecholamines, is an important substrate of COMT.

Catechol-O-methyltransferase – Wikipedia

Their effects and significance also in the treatment of de novo patients need to be clarified. Chromosome 22 human [1]. Both pharmacokinetically and clinically the mg dose of entacapone is the most effective innhibidores compared with placebo.

This “triple therapy” is becoming a standard in the treatment of Parkinson’s disease. Journal of Neural Transmission.

Tryptophan hydroxylase Aromatic L-amino acid decarboxylase Aralkylamine N-acetyltransferase Acetylserotonin O-methyltransferase. Catechol- O -methyltransferase is involved in the inactivation of the catecholamine neurotransmitters dopamineepinephrineand norepinephrine. Zhu BT October Neurotransmitters and their receptors”.

The enzyme introduces a methyl group to the catecholamine, which is donated by S-adenosyl methionine SAM.
