Betaine-homocysteine methyltransferase Homocysteine methyltransferase Methionine synthase. Entacapone acts mainly peripherally whereas tolcapone acts both peripherally and centrally.

The gene is associated with allelic variants. Thus, COMT inhibitors are clinically significant and beneficial adjunct to levodopa therapy in Parkinson’s disease patients with end-of-dose fluctuations. Levodopaa precursor of catecholamines, is an important substrate of COMT. The Journal of Biological Chemistry.

COMT inhibition in the treatment of Parkinson’s disease.

Their effects and significance also in the treatment of de novo patients need to be clarified. However, tolcapone is clinically restricted owning to its inhibidored hepatotoxicity and other related digestive disorders. Both pharmacokinetically and clinically the mg dose of entacapone is the most effective dose compared with placebo.

Comparable effects on similar cognitive tasks, the frontal lobes, and the neurotransmitter dopamine have also all been linked to schizophrenia.

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 during life.

However, there seems to be a trend for tolcapone to induce more often diarrhoea and increase in liver transaminases compared with entacapone. Zhu BT October Oroszi G, Goldman D December Cholinesterase AcetylcholinesteraseButyrylcholinesterase.

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. Allosteric regulation Cooperativity Enzyme inhibitor Enzyme activator. Inhbidores and Cellular Biology portal. Both entacapone and tolcapone are well-tolerated.

Genetic variation with functional impact on cortical dopamine tone has a strong influence on reward experience in the flow of daily life.

Tyrosine hydroxylase Aromatic L-amino acid decarboxylase Dopamine beta-hydroxylase Phenylethanolamine N-methyltransferase. From Wikipedia, the free encyclopedia. Available structures PDB Ortholog search: Two of the nitrocatechols, entacapone As the regulation of catecholamines is impaired in a inuibidores of medical conditions, several pharmaceutical drugs target COMT to alter its inhibiddores and therefore the availability of catecholamines.

Given the preferential role inhigidores COMT in prefrontal dopamine degradation, the ValMet polymorphism is thought to exert its effects on cognition by modulating dopamine signaling in the frontal lobes.
