The dyskinesias are managed by decreasing the daily levodopa dose in Parkinson’s disease patients with end-of-dose fluctuations. The Central Nervous System. Please improve this by adding secondary or tertiary sources.

Betaine-homocysteine methyltransferase Homocysteine methyltransferase Methionine synthase. From Wikipedia, the free encyclopedia. The effect size of genotypic moderation was quite large: It is increasingly recognised that allelic variation at the COMT gene are also relevant for emotional processing, as they seem to influence the comf between prefrontal and limbic regions.

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 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.

COMT inhhibidores the name given to the gene that codes for this enzyme. As the regulation of catecholamines is impaired in a number of medical conditions, several pharmaceutical comy target COMT to alter its activity and therefore the availability of catecholamines.

Retrieved from ” https: The O in the name stands for oxygennot for ortho.

Cholinesterase AcetylcholinesteraseButyrylcholinesterase. Tryptophan hydroxylase Aromatic L-amino acid decarboxylase Aralkylamine N-acetyltransferase Acetylserotonin O-methyltransferase.

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

Oroszi G, Goldman D December Histamine N-methyltransferase Diamine oxidase. Both entacapone and tolcapone are well-tolerated. COMT inhibiores include tolcaponeentacapone and opicaponewhich are used in the treatment of Parkinson’s disease. This page was last edited on 21 Novemberat Entacapone acts mainly peripherally whereas tolcapone acts both peripherally and centrally.

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. More reference expression data. The Journal of Biological Chemistry. However, tolcapone is clinically restricted owning to its increased hepatotoxicity and other related digestive disorders.
