Dopamine
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]
2-Hydroxyphenethylamine
2-Hydroxyphenethylamine, also known as beta-phenethanolamine or 2-amino-1-phenylethanol, belongs to the class of organic compounds known as aralkylamines. These are alkylamines in which the alkyl group is substituted at one carbon atom by an aromatic hydrocarbyl group. It is the simplest member of the class of phenylethanolamines that is 2-aminoethanol bearing a phenyl substituent at the 1-position. 2-Hydroxyphenethylamine exists in all living organisms, ranging from bacteria to humans. 2-Hydroxyphenethylamine ia an amine found in the brain. It may be modulator of sympathetic functions. Its derivatives are adrenergic agonists and antagonists. Simple amine found in the brain. It may be modulator of sympathetic functions. Its derivatives are adrenergic agonists and antagonists. It is also used in chemical industry. [HMDB] 2-Amino-1-phenylethanol is an analogue of noradrenaline.
3,4-Dihydroxyphenylglycol
3,4-Dihydroxyphenylglycol, also known as DHPG or DOPEG, belongs to the class of organic compounds known as catechols. Catechols are compounds containing a 1,2-benzenediol moiety. 3,4-Dihydroxyphenylglycol is an extremely weak basic (essentially neutral) compound. 3,4-Dihydroxyphenylglycol exists in all living organisms, ranging from bacteria to plants to humans. It is a potent antioxidant (PMID: 30007612). In mammals, 3,4-Dihydroxyphenylglycol is the primary metabolite of norepinephrine and is generated through the action of the enzyme monoamine oxidase (MAO). DHPG is then further metabolized by the enzyme Catechol-O-methyltransferase (COMT) to 3-methoxy-4-hydroxyphenylglycol (MHPG). Within humans, 3,4-dihydroxyphenylglycol participates in a number of enzymatic reactions. In particular, 3,4-dihydroxyphenylglycol can be biosynthesized from 3,4-dihydroxymandelaldehyde; which is mediated by the enzyme alcohol dehydrogenase 1A. In addition, 3,4-dihydroxyphenylglycol and guaiacol can be converted into vanylglycol and pyrocatechol through its interaction with the enzyme catechol O-methyltransferase. Outside of the human body, 3,4-dihydroxyphenylglycol is found, on average, in the highest concentration in olives. High levels of DHPG (up to 368 mg/kg of dry weight) have been found in the pulp of natural black olives. This could make 3,4-dihydroxyphenylglycol a potential biomarker for the consumption of olives and olive oil. 3,4-Dihydroxyphenylglycol has been linked to Menkes disease (PMID: 19234788). DHPG level are lower in Menkes patients (3.57 ± 0.40 nM) than healthy infants 8.91 ± 0.77 nM). Menkes disease (also called “kinky hair disease”) is an X-linked recessive neurodevelopmental disorder caused by defects in a gene that encodes a copper-transporting ATPase (ATP7A). Affected infants typically appear healthy at birth and show normal neurodevelopment for 2-3 months. Subsequently there is loss of milestones (e.g., smiling, visual tracking, head control) and death in late infancy or childhood (PMID: 19234788). 3,4-Dihydroxyphenylglycol (DOPEG) is a normal norepinephrine metabolite present in CSF, plasma and urine in humans (PMID 6875564). In healthy individuals there is a tendency for free DOPEG to increase and for conjugated DOPEG to decrease with age; plasmatic DOPEG levels are significantly lower in depressed patients as compared to healthy controls (PMID 6671452). DL-1-(3,4-Dihydroxyphenyl)-1,2-ethanediol is found in olive. 4-(1,2-Dihydroxyethyl)benzene-1,2-diol, a normal norepinephrine metabolite, is found to be associated with Menkes syndrome.
Epinephrine
Epinephrine, also known as adrenaline, is both a neurotransmitter and a hormone. It plays an important role in your body’s “fight-or-flight” response. It’s also used as a medication to treat many life-threatening conditions. Epinephrine is a catecholamine, a sympathomimetic monoamine derived from the amino acids phenylalanine and tyrosine. It is the active sympathomimetic hormone secreted from the adrenal medulla in most species. It stimulates both the alpha- and beta- adrenergic systems, causes systemic vasoconstriction and gastrointestinal relaxation, stimulates the heart, and dilates bronchi and cerebral vessels. It is used in asthma and cardiac failure and to delay absorption of local anesthetics. Epinephrine also constricts arterioles in the skin and gut while dilating arterioles in leg muscles. It elevates the blood sugar level by increasing hydrolysis of glycogen to glucose in the liver, and at the same time begins the breakdown of lipids in adipocytes. Epinephrine has a suppressive effect on the immune system. [HMDB] Epinephrine, also called adrenaline, is both a hormone and a neurotransmitter. As a hormone, it’s made and released by your adrenal glands, which are hat-shaped glands that sit on top of each kidney. As a central nervous system neurotransmitter, it’s a chemical messenger that helps transmit nerve signals across nerve endings to another nerve cell, muscle cell or gland cell. Epinephrine is part of your sympathetic nervous system, which is part of your body’s emergency response system to danger — the “fight-or-flight” response. Medically, the flight-or-flight response is known as the acute stress response. Epinephrine is also called a catecholamine, as are norepinephrine and dopamine. They’re given this name because of a certain molecule in its structure. As a hormone, epinephrine is made from norepinephrine inside of your adrenal gland. As a neurotransmitter, epinephrine plays a small role. Only a small amount is produced in your nerves. It plays a role in metabolism, attention, focus, panic and excitement. Abnormal levels are linked to sleep disorders, anxiety, hypertension and lowered immunity. Epinephrine’s major action is in its role as a hormone. Epinephrine is released by your adrenal glands in response to stress. This reaction causes a number of changes in your body and is known as the fight-or-flight response.
Norepinephrine
Norepinephrine is the precursor of epinephrine that is secreted by the adrenal medulla and is a widespread central and autonomic neurotransmitter. Norepinephrine is the principal transmitter of most postganglionic sympathetic fibers and of the diffuse projection system in the brain arising from the locus ceruleus. It is also found in plants and is used pharmacologically as a sympathomimetic. Norepinephrine is elevated in the urine of people who consume bananas. Norepinephrine is also a microbial metabolite; urinary noradrenaline is produced by Escherichia, Bacillus, and Saccharomyces (PMID: 24621061). Norepinephrine is found in alcoholic beverages, banana peels and pulp (Musa paradisiaca), red plum fruit (Prunus domestica), orange pulp (Citrus sinensis), potato tubers (Solanum tuberosum), and whole purslane (Portulaca oleracea). P. oleracea is the richest of these sources. Norepinephrine has also been identified as a uremic toxin according to the European Uremic Toxin Working Group (PMID: 22626821). Present in banana peel and pulp (Musa paradisiaca), red plum fruit (Prunus domestica), orange pulp (Citrus sinensis), potato tubers (Solanum tuberosum) and whole purslane (Portulaca oleracea). P. oleracea is the richest of these sources. xi-Norepinephrine is found in many foods, some of which are potato, green vegetables, alcoholic beverages, and fruits.

Tyramine
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.

3-Methoxytyramine
3-methoxytyramine, also known as 4-(2-amino-Ethyl)-2-methoxy-phenol or 3-O-Methyldopamine, is classified as a member of the Methoxyphenols. Methoxyphenols are compounds containing a methoxy group attached to the benzene ring of a phenol moiety. 3-methoxytyramine is considered to be slightly soluble (in water) and acidic. 3-methoxytyramine can be found primarily in human brain and most tissues tissues; and in blood, cerebrospinal fluid (csf) or urine. Within a cell, 3-methoxytyramine is primarily located in the cytoplasm The O-methylated derivative of dopamine. Dopamine is methylated by catechol-O-methyltransferase (COMT) to make 3-Methoxytyramine. This compound can be broken down to homovanillic acid by monoamine oxidase and aldehyde dehydrogenase. Elevated concentrations of this compound are indicated for a variety of brain and carcinoid tumors as well as certain mental disorders.

Isoetharine
Isoetharine is only found in individuals that have used or taken this drug. It is a selective adrenergic beta-2 agonist used as fast acting bronchodilator for emphysema, bronchitis and asthma. [PubChem]The pharmacologic effects of isoetharine are attributable to stimulation through beta-adrenergic receptors of intracellular adenyl cyclase, the enzyme that catalyzes the conversion of adenosine triphosphate (ATP) to cyclic AMP. Increased cyclic AMP levels are associated with relaxation of bronchial smooth muscle and inhibition of release of mediators of immediate hypersensitivity from cells, especially from mast cells.

Phenylethylamine
Phenylethylamine (PEA) is an aromatic amine, which is a colorless liquid at room temperature. It is soluble in water, ethanol, and ether. Similar to other low-molecular-weight amines, it has a fishy odor. Upon exposure to air, it forms a solid carbonate salt with carbon dioxide. Phenethylamine is strongly basic and forms a stable crystalline hydrochloride salt with a melting point of 217 °C. Phenethylamine is also a skin irritant and possible sensitizer. Phenethylamine also has a constitutional isomer (+)-phenylethylamine (1-phenylethylamine), which has two stereoisomers: (R)-(+)-1-phenylethylamine and (S)-(-)-1-phenylethylamine. In the human brain, 2-phenethylamine is believed to function as a neuromodulator or neurotransmitter (a trace amine). Phenethylamine can be biosynthesized from the amino acid phenylalanine by enzymatic decarboxylation. It is also found in many foods such as chocolate, especially after microbial fermentation. However trace amounts from food are quickly metabolized by the enzyme MAO-B (into phenylacetic acid), preventing significant concentrations from reaching the brain. Phenylethylamine is a precursor to the neurotransmitter phenylethanolamine. High levels of PEA have been found in the urine of schizophrenics but it is not significantly elevated in the serum or CSF of schizophrenics (PMID:7906896, PMID:7360842).¬† Urinary levels of PEA are significantly lower in children with attention deficit hyperactivity disorder (ADHD) (PMID:12205654).¬† It has been found that PEA is the primary compound found in carnivore (especially cat) urine that leads to rodent (mouse and rat) avoidance. In other words, phenylethylamine is useful for scaring off rodent pests.¬† Quantitative HPLC analysis across 38 mammalian species has shown that PEA production in urine is especially enhanced in carnivores, with some producing >3,000-fold more than herbivores (PMID:21690383). Phenethylamine has been found to be a metabolite of Bacillus, Enterococcus and Lactobacillus (PMID:22953951; PMID:17307265; PMID:16630269).

Vanillylamine
Vanillylamine is prepared by reacting vanillin with hydroxylamine or the salts thereof in the presence of an organic salt, which may optionally be produced in situ, wherein the reaction is carried out in an inorganic or organic acid as diluent, and subsequently hydrogenating the resulting vanillyloxime with hydrogen in the presence of a suitable catalyst and an organic and/or inorganic acid.It inhibits microsomal enzyme function; RN given refers to parent cpd. Vanillylamine is a component of capsaicin.In Pseudomonas fluorescens B56 under growing conditions, the cells metabolized vanillylamine to vanillin, and vanillin to vanillic acid and a small amount of vanillyl alcohol. Under non-growing conditions, the cells produced vanillin, vanillic acid and protocatechuic acid from vanillylamine, and vanillic acid supplied to the medium was converted to protocatechuic acid. It is thus suggested that vanillylamine is metabolized to vanillic acid through vanillin by Pseudomonas fluorescens B56 in a rich medium, however, in a starving medium, the bacterial strain further metabolizes vanillic acid to protocatechuic acid. The vanillylamine metabolic activity was slowly induced by the substrate. Vanillylamine is prepared by reacting vanillin with hydroxylamine or the salts thereof in the presence of an organic salt, which may optionally be produced in situ, wherein the reaction is carried out in an inorganic or organic acid as diluent, and subsequently hydrogenating the resulting vanillyloxime with hydrogen in the presence of a suitable catalyst and an organic and/or inorganic acid.It inhibits microsomal enzyme function; RN given refers to parent cpd Vanillylamine is an aralkylamino compound. It is functionally related to a vanillyl alcohol. It is a conjugate base of a vanillylamine(1+). Vanillylamine is a natural product found in Capsicum annuum with data available. Vanillylamine is a derivative of vanillin is synthesized through a transaminase reaction in the phenylpropanoid pathway of capsaicinoid synthesis[1].
Desglymidodrine
Desglymidodrine is a metabolite of midodrine. Midodrine (brand names Amatine, ProAmatine, Gutron) is a vasopressor/antihypotensive agent. Midodrine was approved in the United States by the Food and Drug Administration (FDA) in 1996 for the treatment of dysautonomia and orthostatic hypotension. In August 2010, the FDA proposed withdrawing this approval because the manufacturer, Shire plc, has failed to complete required studies after the medicine reached the market. (Wikipedia) Midodrine, a prodrug, is converted after oral administration into its active drug, desglymidodrine, which acts as an alpha(1)-adrenoceptor stimulant. (PMID: 17901021) Through selective alpha(1)-adrenergic receptor-binding, desglymidodrine, the active metabolite of midodrine, raises blood pressure by enhancing venous and arterial tone. (PMID: 12904123) Desglymidodrine (ST 1059), the active metabolite of Midodrine (HY-12749), is a selective α1-adrenoceptor agonist. Desglymidodrine is an effective arterial and venous vasoconstrictor and can be used to regulate blood pressure[1][2].
N-Methylphenethylamine
N-Methylphenethylamine is a natural product found in Acacia kettlewelliae, Senegalia berlandieri, and other organisms with data available.
N-Acetyldopamine
N-Acetyldopamine also known as NADA is an acetylated form of dopamine. It is an endogenously produced derivative or metabolite of dopamine. It belongs to the family of compounds known as catecholamines and derivatives. These are compounds containing 4-(2-aminoethyl) pyrocatechol [4-(2-aminoethyl) benzene-1,2-diol] or a derivative thereof. While NADA has been found in the human liver, kidney, and urine, it is unclear what its role is in mammal physiology (PMID: 16179545). NADA exists in both free and conjugated (glucuronide) forms. Conjugated NADA accounts for about 90\\\% of the total excretion of NADA. Urinary excretion of total N-acetyldopamine averages 0.485 micromoles/day in healthy humans (PMID: 6513727). The concentration of NADA is thirteen times higher in children with neuroblastoma than in normal subjects (PMID: 1321164). NADA is known to be a sepiapterin reductase inhibitor (PMID: 16179545). N-acetyldopamine has been shown to inhibit lipopolysaccharide-induced lipid peroxidation in rat brains (PMID: 16179545). N-acetyldopamine (NADA) is a catecholamine that is used by insects as sclerotizing precursors to harden their cuticle[1].
3,4-Dimethoxyphenylethylamine
3,4-Dimethoxyphenylethylamine, also known as 3,4-DMPEA or DMPEA is an endogenous metabolite found in urine that belongs to both the phenethylamine and catecholamine families. DMPEA is an analogue of dopamine (3,4-dihydroxyphenethylamine), with a substitution of the hydroxy groups with methoxy groups. DMPEA is also structurally similar to mescaline (3,4,5-trimethoxyphenylethylamine) and occurs naturally alongside it in various species of cacti such as the San Pedro and Peruvian Torch (PMID: 5511715, 925910, 600028). DMPEA received wide attention after it was proposed as a biomarker in schizophrenic patients urine, however later studies revealed that DMPEA is also excreted by non-schizophrenics (PMID: 709888). DMPEA has little known bioactivity, but it has some action as a monoamine oxidase inhibitor (PMID: 886445). DMPEA has also been shown to have neurotoxic effects, especially in the nigrostriatal system and among dopaminergic neurons (PMID: 9409711, 9134983). DMPEA appears to be an inhibitor of mitochondrial complex I (PMID: 9409711).
Benzphetamine
Benzphetamine is only found in individuals that have used or taken this drug. It is a sympathomimetic agent with properties similar to dextroamphetamine. It is used in the treatment of obesity. (From Martindale, The Extra Pharmacopoeia, 30th ed, p1222)Although the mechanism of action of the sympathomimetic appetite suppressants in the treatment of obesity is not fully known, these medications have pharmacological effects similar to those of amphetamines. Amphetamine and related sympathomimetic medications (such as benzphetamine) are thought to stimulate the release of norepinephrine and/or dopamine from storage sites in nerve terminals in the lateral hypothalamic feeding center, thereby producing a decrease in appetite. This release is mediated by the binding of benzphetamine to centrally located adrenergic receptors.

6-Hydroxydopamine
6-Hydroxydopamine, also known as 6-OHDA or oxidopamina, belongs to the class of organic compounds known as catecholamines and derivatives. Catecholamines and derivatives are compounds containing 4-(2-Aminoethyl)pyrocatechol [4-(2-aminoethyl)benzene-1,2-diol] or a derivative thereof formed by substitution. The main use for oxidopamine in scientific research is to induce Parkinsonism in laboratory animals such as mice, rats and monkeys, in order to develop and test new medicines and treatments for Parkinsons disease. In order to induce this condition in animals, around 70\\% of the dopaminergic neurons in the substantia nigra of the brain must be destroyed, and this is achieved either with oxidopamine or MPTP. 6-OHDA is thought to enter the neurons via the dopamine and noradrenaline (norepinephrine) reuptake transporters. Oxidopamine toxicity in neonatal rodents is also used as an animal model for the Lesch-Nyhan syndrome. Both these agents likely destroy neurons by generating reactive oxygen species such as superoxide radical. Oxidopamine is often used in conjunction with a selective noradrenaline reuptake inhibitor (such as desipramine) to selectively destroy dopaminergic neurons. 6-Hydroxydopamine is a naturally occurring amine in human urine. 5-Hydroxydopamine concentration in urine of DOPA treated Parkinsons patients was significantly higher than inpatients not treated or normal controls.

4-Methoxytyramine
4-Methoxytyramine is a catecholamine derivative. Catecholamines are important components of the central nervous system. A number of diseases are characterized by abnormal levels of catecholamines. For example, patients with Parkinsons disease have lower levels of dopamine than normal. L-3,4-Dihydroxyphennylalanune (L-Dopa), a catechol a-amino acid, is widely used in the treatment of Parkinsons disease. When L-Dopa is given orally to patients, the most prominent metabolite is 3-methoxy-4-hydroxyphenylalanine. However, a part of L-Dopa is methylated to 3-hydroxy-4-methylphenylalanine and to 3-hydroxy-4-methoxyphenethylamine. It has been reported that 4-O-methylation of catecholamines is implicated in some neuropsychiatric disorders and thus 3-hydroxy-4-methoxyphenethylamine appears to be the endogenous "toxin" in Parkinsons disease. Consequently, the determination of plasma levels of 3-hydroxy-4-methoxyphenethylamine is important following oral L-Dopa therapy (PMID: 6518609).

Epinephrine glucuronide
Epinephrine glucuronide is a natural human metabolite of epinephrine generated in the liver by UDP glucuonyltransferase. Glucuronidation is used to assist in the excretion of toxic substances, drugs or other substances that cannot be used as an energy source. Glucuronic acid is attached via a glycosidic bond to the substance, and the resulting glucuronide, which has a much higher water solubility than the original substance, is eventually excreted by the kidneys. Epinephrine glucuronide is a natural human metabolite of epinephrine generated in the liver by UDP glucuonyltransferase.
3,4-Dihydroxybenzylamine
3,4-Dihydroxybenzylamine is an alternative substrates for dopamine that is a member of the catecholamine family in the brain, and is a precursor to epinephrine and norepinephrine. Catecholamines contain a catechol group, and are derived from the amino acid and tyrosine. They are produced mainly by the chromaffin cells of the adrenal medulla and the postganglionic fibers of the sympathetic nervous system. Catecholamine synthesis is inhibited by alpha-Methyltyrosine, by inhibiting tyrosine-3 monooxygenase.Wikipedia [HMDB] 3,4-Dihydroxybenzylamine is an alternative substrates for dopamine that is a member of the catecholamine family in the brain, and is a precursor to epinephrine and norepinephrine.
