Norepinephrine degradation. Catechol-O-methyltransferase is shown in green boxes.[5] [6]Catechol-O-methyltransferase (COMT; EC 2.1.1.6) is one of several enzymes that degrade catecholamines (neurotransmitters such as dopamine, epinephrine, and norepinephrine), catecholestrogens, and various drugs and substances having a catechol structure.

Catechol (/ ˈ k æ t ɪ tʃ ɒ l / or / ˈ k æ t ɪ k ɒ l /), also known as pyrocatechol or 1,2-dihydroxybenzene, is an organic compound with the molecular formula C 6 H 4 (OH) 2.It is the ortho isomer of the three isomeric benzenediols.
Catechol. A catecholamine (/ ˌ k æ t ə ˈ k oʊ l ə m iː n /; abbreviated CA) is a monoamine neurotransmitter, an organic compound that has a catechol (benzene with two hydroxyl side groups next to each other) and a side-chain amine. [1] Catechol can be either a free molecule or a substituent of a larger molecule, where it represents a 1,2 ...
Sympathomimetic drugs are used to treat cardiac arrest and low blood pressure, or even delay premature labor, among other things. These drugs can act through several mechanisms, such as directly activating postsynaptic receptors , blocking breakdown and reuptake of certain neurotransmitters, or stimulating production and release of catecholamines.
Metabolism of levodopa by catechol-O-methyltransferase (COMT) and aromatic L-amino acid decarboxylase (AADC). COMT inhibitors prevent the conversion of levodopa to 3- O -methyldopa. A catechol- O -methyltransferase inhibitor ( COMT inhibitor ) is a drug that inhibits the enzyme catechol- O -methyltransferase .
