Dopamine

alpha-(3,4-Dihydroxyphenyl)-beta-aminoethane

C8H11NO2 (153.0789746)


Dopamine is a member of the catecholamine family of neurotransmitters in the brain and is a precursor to epinephrine (adrenaline) and norepinephrine (noradrenaline). Dopamine is synthesized in the body (mainly by nervous tissue and adrenal glands) first by the hydration of the amino acid tyrosine to DOPA by tyrosine hydroxylase and then by the decarboxylation of DOPA by aromatic-L-amino-acid decarboxylase. Dopamine is a major transmitter in the extrapyramidal system of the brain, and important in regulating movement. A family of receptors (dopamine receptors) mediates its action, which plays a major role in reward-motivated behaviour. Dopamine has many other functions outside the brain. In blood vessels, dopamine inhibits norepinephrine release and acts as a vasodilator (at normal concentrations); in the kidneys, it increases sodium excretion and urine output; in the pancreas, it reduces insulin production; in the digestive system, it reduces gastrointestinal motility and protects intestinal mucosa; and in the immune system, it reduces the activity of lymphocytes. Parkinsons disease, a degenerative condition causing tremor and motor impairment, is caused by a loss of dopamine-secreting neurons in an area of the midbrain called the substantia nigra. There is evidence that schizophrenia involves altered levels of dopamine activity, and most antipsychotic drugs used to treat this are dopamine antagonists, which reduce dopamine activity. Attention deficit hyperactivity disorder, bipolar disorder, and addiction are also characterized by defects in dopamine production or metabolism. It has been suggested that animals derived their dopamine-synthesizing machinery from bacteria via horizontal gene transfer that may have occurred relatively late in evolutionary time. This is perhaps a result of the symbiotic incorporation of bacteria into eukaryotic cells that gave rise to mitochondria. Dopamine is elevated in the urine of people who consume bananas. When present in sufficiently high levels, dopamine can be a neurotoxin and a metabotoxin. A neurotoxin is a compound that disrupts or attacks neural tissue. A metabotoxin is an endogenously produced metabolite that causes adverse health effects at chronically high levels. Chronically high levels of dopamine are associated with neuroblastoma, Costello syndrome, leukemia, phaeochromocytoma, aromatic L-amino acid decarboxylase deficiency, and Menkes disease (MNK). High levels of dopamine can lead to hyperactivity, insomnia, agitation and anxiety, depression, delusions, excessive salivation, nausea, and digestive problems. A study has shown that urinary dopamine is produced by Bacillus and Serratia (PMID: 24621061) Occurs in several higher plants, such as banana (Musa sapientum). As a member of the catecholamine family, dopamine is a precursor to norepinephrine (noradrenaline) and then epinephrine (adrenaline) in the biosynthetic pathways for these neurotransmitters. Dopamine is elevated in the urine of people who consume bananas. Dopamine is found in many foods, some of which are garden onion, purslane, garden tomato, and swiss chard. Dopamine (DA, a contraction of 3,4-dihydroxyphenethylamine) is a neuromodulatory molecule that plays several important roles in cells. It is an organic chemical of the catecholamine and phenethylamine families. Dopamine constitutes about 80\% of the catecholamine content in the brain. It is an amine synthesized by removing a carboxyl group from a molecule of its precursor chemical, L-DOPA, which is synthesized in the brain and kidneys. Dopamine is also synthesized in plants and most animals. In the brain, dopamine functions as a neurotransmitter—a chemical released by neurons (nerve cells) to send signals to other nerve cells. Neurotransmitters are synthesized in specific regions of the brain, but affect many regions systemically. The brain includes several distinct dopamine pathways, one of which plays a major role in the motivational component of reward-motivated behavior. The anticipation of most types of rewards increases the level of dopamine in the brain,[4] and many addictive drugs increase dopamine release or block its reuptake into neurons following release.[5] Other brain dopamine pathways are involved in motor control and in controlling the release of various hormones. These pathways and cell groups form a dopamine system which is neuromodulatory.[5] In popular culture and media, dopamine is often portrayed as the main chemical of pleasure, but the current opinion in pharmacology is that dopamine instead confers motivational salience;[6][7][8] in other words, dopamine signals the perceived motivational prominence (i.e., the desirability or aversiveness) of an outcome, which in turn propels the organism's behavior toward or away from achieving that outcome.[8][9] Outside the central nervous system, dopamine functions primarily as a local paracrine messenger. In blood vessels, it inhibits norepinephrine release and acts as a vasodilator; in the kidneys, it increases sodium excretion and urine output; in the pancreas, it reduces insulin production; in the digestive system, it reduces gastrointestinal motility and protects intestinal mucosa; and in the immune system, it reduces the activity of lymphocytes. With the exception of the blood vessels, dopamine in each of these peripheral systems is synthesized locally and exerts its effects near the cells that release it. Several important diseases of the nervous system are associated with dysfunctions of the dopamine system, and some of the key medications used to treat them work by altering the effects of dopamine. Parkinson's disease, a degenerative condition causing tremor and motor impairment, is caused by a loss of dopamine-secreting neurons in an area of the midbrain called the substantia nigra. Its metabolic precursor L-DOPA can be manufactured; Levodopa, a pure form of L-DOPA, is the most widely used treatment for Parkinson's. There is evidence that schizophrenia involves altered levels of dopamine activity, and most antipsychotic drugs used to treat this are dopamine antagonists which reduce dopamine activity.[10] Similar dopamine antagonist drugs are also some of the most effective anti-nausea agents. Restless legs syndrome and attention deficit hyperactivity disorder (ADHD) are associated with decreased dopamine activity.[11] Dopaminergic stimulants can be addictive in high doses, but some are used at lower doses to treat ADHD. Dopamine itself is available as a manufactured medication for intravenous injection. It is useful in the treatment of severe heart failure or cardiogenic shock.[12] In newborn babies it may be used for hypotension and septic shock.[13] Dopamine is synthesized in a restricted set of cell types, mainly neurons and cells in the medulla of the adrenal glands.[22] The primary and minor metabolic pathways respectively are: Primary: L-Phenylalanine → L-Tyrosine → L-DOPA → Dopamine[19][20] Minor: L-Phenylalanine → L-Tyrosine → p-Tyramine → Dopamine[19][20][21] Minor: L-Phenylalanine → m-Tyrosine → m-Tyramine → Dopamine[21][23][24] The direct precursor of dopamine, L-DOPA, can be synthesized indirectly from the essential amino acid phenylalanine or directly from the non-essential amino acid tyrosine.[25] These amino acids are found in nearly every protein and so are readily available in food, with tyrosine being the most common. Although dopamine is also found in many types of food, it is incapable of crossing the blood–brain barrier that surrounds and protects the brain.[26] It must therefore be synthesized inside the brain to perform its neuronal activity.[26] L-Phenylalanine is converted into L-tyrosine by the enzyme phenylalanine hydroxylase, with molecular oxygen (O2) and tetrahydrobiopterin as cofactors. L-Tyrosine is converted into L-DOPA by the enzyme tyrosine hydroxylase, with tetrahydrobiopterin, O2, and iron (Fe2+) as cofactors.[25] L-DOPA is converted into dopamine by the enzyme aromatic L-amino acid decarboxylase (also known as DOPA decarboxylase), with pyridoxal phosphate as the cofactor.[25] Dopamine itself is used as precursor in the synthesis of the neurotransmitters norepinephrine and epinephrine.[25] Dopamine is converted into norepinephrine by the enzyme dopamine β-hydroxylase, with O2 and L-ascorbic acid as cofactors.[25] Norepinephrine is converted into epinephrine by the enzyme phenylethanolamine N-methyltransferase with S-adenosyl-L-methionine as the cofactor.[25] Some of the cofactors also require their own synthesis.[25] Deficiency in any required amino acid or cofactor can impair the synthesis of dopamine, norepinephrine, and epinephrine.[25] Degradation Dopamine is broken down into inactive metabolites by a set of enzymes—monoamine oxidase (MAO), catechol-O-methyl transferase (COMT), and aldehyde dehydrogenase (ALDH), acting in sequence.[27] Both isoforms of monoamine oxidase, MAO-A and MAO-B, effectively metabolize dopamine.[25] Different breakdown pathways exist but the main end-product is homovanillic acid (HVA), which has no known biological activity.[27] From the bloodstream, homovanillic acid is filtered out by the kidneys and then excreted in the urine.[27] The two primary metabolic routes that convert dopamine into HVA are:[28] Dopamine → DOPAL → DOPAC → HVA – catalyzed by MAO, ALDH, and COMT respectively Dopamine → 3-Methoxytyramine → HVA – catalyzed by COMT and MAO+ALDH respectively In clinical research on schizophrenia, measurements of homovanillic acid in plasma have been used to estimate levels of dopamine activity in the brain. A difficulty in this approach however, is separating the high level of plasma homovanillic acid contributed by the metabolism of norepinephrine.[29][30] Although dopamine is normally broken down by an oxidoreductase enzyme, it is also susceptible to oxidation by direct reaction with oxygen, yielding quinones plus various free radicals as products.[31] The rate of oxidation can be increased by the presence of ferric iron or other factors. Quinones and free radicals produced by autoxidation of dopamine can poison cells, and there is evidence that this mechanism may contribute to the cell loss that occurs in Parkinson's disease and other conditions.[32]

   

4-Hydroxyphenylpyruvic acid

4-Hydroxy-alpha-oxobenzenepropanoic acid

C9H8O4 (180.0422568)


3-(4-hydroxy-phenyl)pyruvic acid, also known as 4-hydroxy a-oxobenzenepropanoate or 3-(p-hydroxyphenyl)-2-oxopropanoate, belongs to phenylpyruvic acid derivatives class of compounds. Those are compounds containing a phenylpyruvic acid moiety, which consists of a phenyl group substituted at the second position by an pyruvic acid. 3-(4-hydroxy-phenyl)pyruvic acid is slightly soluble (in water) and a moderately acidic compound (based on its pKa). 3-(4-hydroxy-phenyl)pyruvic acid can be synthesized from pyruvic acid. 3-(4-hydroxy-phenyl)pyruvic acid can also be synthesized into 4-hydroxyphenylpyruvic acid oxime. 3-(4-hydroxy-phenyl)pyruvic acid can be found in a number of food items such as garden onion (variety), rose hip, sourdough, and horseradish tree, which makes 3-(4-hydroxy-phenyl)pyruvic acid a potential biomarker for the consumption of these food products. 3-(4-hydroxy-phenyl)pyruvic acid can be found primarily in blood and urine, as well as in human prostate tissue. 3-(4-hydroxy-phenyl)pyruvic acid exists in all eukaryotes, ranging from yeast to humans. In humans, 3-(4-hydroxy-phenyl)pyruvic acid is involved in few metabolic pathways, which include disulfiram action pathway, phenylalanine and tyrosine metabolism, and tyrosine metabolism. 3-(4-hydroxy-phenyl)pyruvic acid is also involved in several metabolic disorders, some of which include tyrosinemia type I, phenylketonuria, tyrosinemia, transient, of the newborn, and alkaptonuria. Moreover, 3-(4-hydroxy-phenyl)pyruvic acid is found to be associated with hawkinsinuria and phenylketonuria. 4-Hydroxyphenylpyruvic acid (4-HPPA) is a keto acid that is involved in the tyrosine catabolism pathway. It is a product of the enzyme (R)-4-hydroxyphenyllactate dehydrogenase (EC 1.1.1.222) and is formed during tyrosine metabolism. The conversion from tyrosine to 4-HPPA is catalyzed by tyrosine aminotransferase. Additionally, 4-HPPA can be converted to homogentisic acid which is one of the precursors to ochronotic pigment. The enzyme 4-hydroxyphenylpyruvic acid dioxygenase (HPD) catalyzes the reaction that converts 4-hydroxyphenylpyruvic acid to homogentisic acid. A deficiency in the catalytic activity of HPD is known to lead to tyrosinemia type III, an autosomal recessive disorder characterized by elevated levels of blood tyrosine and massive excretion of tyrosine derivatives into urine. It has been shown that hawkinsinuria, an autosomal dominant disorder characterized by the excretion of hawkinsin, may also be a result of HPD deficiency (PMID: 11073718). Moreover, 4-hydroxyphenylpyruvic acid is also found to be associated in phenylketonuria, which is also an inborn error of metabolism. There are two isomers of HPPA, specifically 4HPPA and 3HPPA, of which 4HPPA is the most common. 4-HPPA has been found to be a microbial metabolite in Escherichia (ECMDB).

Tyramine

alpha-(4-Hydroxyphenyl)-beta-aminoethane

C8H11NO (137.0840596)


Tyramine is a monoamine compound derived from the amino acid tyrosine. Tyramine is metabolized by the enzyme monoamine oxidase. In foods, it is often produced by the decarboxylation of tyrosine during fermentation or decay. Foods containing considerable amounts of tyramine include fish, chocolate, alcoholic beverages, cheese, soy sauce, sauerkraut, and processed meat. A large dietary intake of tyramine can cause an increase in systolic blood pressure of 30 mmHg or more. Tyramine acts as a neurotransmitter via a G protein-coupled receptor with high affinity for tyramine called TA1. The TA1 receptor is found in the brain as well as peripheral tissues including the kidney. An indirect sympathomimetic, Tyramine can also serve as a substrate for adrenergic uptake systems and monoamine oxidase so it prolongs the actions of adrenergic transmitters. It also provokes transmitter release from adrenergic terminals. Tyramine is a biomarker for the consumption of cheese [Spectral] Tyramine (exact mass = 137.08406) and L-Methionine (exact mass = 149.05105) were not completely separated on HPLC under the present analytical conditions as described in AC$XXX.

Magnoflorine is a member of the class of compounds known as aporphines. Aporphines are quinoline alkaloids containing the dibenzo[de,g]quinoline ring system or a dehydrogenated derivative thereof. Magnoflorine is practically insoluble (in water) and a very weakly acidic compound (based on its pKa). Magnoflorine can be found in a number of food items such as carob, other cereal product, durian, and japanese chestnut, which makes magnoflorine a potential biomarker for the consumption of these food products. Magnoflorine is a chemical compound isolated from the rhizome of Sinomenium acutum and from Pachygone ovata. It is classified as an aporphine alkaloid .
