Catecholamines A catecholamine (/ˌkætəˈkoʊləmiːn/; abbreviated CA), most typically a 3,4-dihydroxyphenethylamine, is a monoamine neurotransmitter, an organic...

enzyme inhibitor and is therefore a drug involved in inhibiting the catecholamine biosynthetic pathway. AMPT inhibits tyrosine hydroxylase whose enzymatic...

The catecholamines are a group of neurotransmitters composed of the endogenous substances dopamine, noradrenaline (norepinephrine), and adrenaline (epinephrine)...

A norepinephrine–dopamine releasing agent (NDRA) is a type of drug which induces the release of norepinephrine (and epinephrine) and dopamine in the body...

Monoamine precursors are precursors of monoamines and monoamine neurotransmitters in the body. The amino acids L-tryptophan and L-5-hydroxytryptophan (5-HTP;...

Catechol-O-methyltransferase (COMT; EC 2.1.1.6) is one of several enzymes that degrade catecholamines (neurotransmitters such as dopamine, epinephrine, and norepinephrine)...

A norepinephrine–dopamine reuptake inhibitor (NDRI) is a type of drug that inhibits the reuptake of the monoamine neurotransmitters norepinephrine and...

processes that take place in cortical cells. The medulla produces the catecholamines, which function to produce a rapid response throughout the body in stress...

These neuroendocrine tumors can be sympathetic, where they release catecholamines into the bloodstream which cause the most common symptoms, including...

an organic chemical of the catecholamine and phenethylamine families. Dopamine constitutes about 80% of the catecholamine content in the brain. It is...

pathophysiology is not well understood, but a sudden massive surge of catecholamines such as adrenaline and noradrenaline from extreme stress or a tumor...

part of the adrenal gland, consisting of chromaffin cells that secrete catecholamines, including epinephrine (adrenaline), norepinephrine (noradrenaline)...

Catecholaminergic means "related to catecholamines". The catecholamine neurotransmitters include dopamine, epinephrine (adrenaline), and norepinephrine...

are a class of G protein-coupled receptors that are targets of many catecholamines like norepinephrine (noradrenaline) and epinephrine (adrenaline) produced...

citation needed] Numerous endogenous compounds – including hormones, catecholamines such as dopamine and noradrenaline, and many trace amines (e.g. adrenaline...

Monoamine-depleting agents are a group of drugs which reversibly deplete one or more of the monoamine neurotransmitters – serotonin, dopamine, and norepinephrine...

trace amine derived from the amino acid tyrosine. Tyramine acts as a catecholamine releasing agent. Notably, it is unable to cross the blood-brain barrier...

antidepressant. Tetrabenazine, a similar agent to reserpine, which also depletes catecholamine stores, and to a lesser degree 5-HT, was shown to induce depression...

treatment. The adrenal medulla is a major contributor to total circulating catecholamines (L-DOPA is at a higher concentration in the plasma), though it contributes...

and anatomical features. These genes have been shown to affect the catecholamine synthesis pathway, with the majority of the genes affecting the fight-or-flight...

artificial vanilla flavorings and is an end-stage metabolite of the catecholamines (epinephrine, and norepinephrine). It is produced via intermediary metabolites...

adrenal medulla. This causes the release of catecholamines. The chromaffin cells release catecholamines: ~80% of adrenaline (epinephrine) and ~20% of...

however, with catecholamine-induced calcium uptake into the sarcoplasmic reticulum, which increases lusitropy. Increased catecholamine levels promote...

Nobel Committee honored him for his work on the release and reuptake of catecholamine neurotransmitters, a class of chemicals in the brain that include epinephrine...

Chemical structures of the catecholamines Sympathomimetic drugs (also known as adrenergic drugs and adrenergic amines) are stimulant compounds which mimic...

catecholamines like epinephrine and norepinephrine. Concomitantly, adrenocortical cells secrete corticosteroids. These hormones (i.e., catecholamines...

sympathetic nervous system is driven by precisely timed releases of a catecholamine, which is a process that determines the concentration of calcium ions...
