Ginsenoside Rg1 is a ginsenoside found in Panax ginseng and Panax japonicus var. major that is dammarane which is substituted by hydroxy groups at the 3beta, 6alpha, 12beta and 20 pro-S positions, in which the hydroxy groups at positions 6 and 20 have been converted to the corresponding beta-D-glucopyranosides, and in which a double bond has been introduced at the 24-25 position. It has a role as a neuroprotective agent and a pro-angiogenic agent. It is a 12beta-hydroxy steroid, a beta-D-glucoside, a tetracyclic triterpenoid, a ginsenoside and a 3beta-hydroxy-4,4-dimethylsteroid. It derives from a hydride of a dammarane. Ginsenosides are a class of steroid glycosides, and triterpene saponins, found exclusively in the plant genus Panax (ginseng). Ginsenosides have been the target of research, as they are viewed as the active compounds behind the claims of ginsengs efficacy. Because ginsenosides appear to affect multiple pathways, their effects are complex and difficult to isolate. Rg1 Appears to be most abundant in Panax ginseng (Chinese/Korean Ginseng). It improves spatial learning and increase hippocampal synaptophysin level in mice, plus demonstrates estrogen-like activity.

Capsaicin

(E)-N-[(4-hydroxy-3-methoxyphenyl)methyl]-8-methylnon-6-enamide

C18H27NO3 (305.1991)


Capsaicin is a capsaicinoid. It has a role as a non-narcotic analgesic, a voltage-gated sodium channel blocker and a TRPV1 agonist. Capsaicin is most often used as a topical analgesic and exists in many formulations of cream, liquid, and patch preparations of various strengths; however, it may also be found in some dietary supplements. Capsaicin is a naturally-occurring botanical irritant in chili peppers, synthetically derived for pharmaceutical formulations. The most recent capsaicin FDA approval was Qutenza, an 8\\\\\\% capsaicin patch dermal-delivery system, indicated for neuropathic pain associated with post-herpetic neuralgia. Capsaicin is a natural product found in Capsicum pubescens, Capsicum, and Capsicum annuum with data available. Capsaicin is a chili pepper extract with analgesic properties. Capsaicin is a neuropeptide releasing agent selective for primary sensory peripheral neurons. Used topically, capsaicin aids in controlling peripheral nerve pain. This agent has been used experimentally to manipulate substance P and other tachykinins. In addition, capsaicin may be useful in controlling chemotherapy- and radiotherapy-induced mucositis. Capsaicin is identified as the primary pungent principle in Capsicum fruits. Hot chili peppers that belong to the plant genus Capsicum (family Solanaceae) are among the most heavily consumed spices throughout the world. The capsaicin content of green and red peppers ranges from 0.1 to 1\\\\\\%. Capsaicin evokes numerous biological effects and thus has been the target of extensive., investigations since its initial identification in 1919. One of the most recognized physiological properties of capsaicin is its selective effects on the peripheral part of the sensory nervous system, particularly on the primary afferent neurons. The compound is known to deplete the neurotransmitter of painful impulses known as substance P from the sensory nerve terminals, which provides a rationale for its use as a versatile experimental tool for studying pain mechanisms and also for pharmacotherapy to treat some peripheral painful states, such as rheumatoid arthritis, post-herpetic neuralgia, post-mastectomy pain syndrome and diabetic neuropathy. Considering the frequent consumption of capsaicin as a food additive and its current therapeutic application, correct assessment of any harmful effects of this compound is important from the public health standpoint. Ingestion of large amounts of capsaicin has been reported to cause histopathological and biochemical changes, including erosion of gastric mucosa and hepatic necrosis. However, there are contradictory data on the mutagenicity of capsaicin. A recent epidemiological study conducted in Mexico revealed that consumers of chili pepper were at higher risk for gastric cancer than non-consumers. However, it remains unclear whether capsaicin present in hot chili pepper is a major causative factor in the aetiology of gastric cancer in humans. A growing number of recent studies have focused on anticarcinogenic or antimutagenic phytochemicals, particularly those included in human diet. In summary, capsaicin has dual effects on chemically induced carcinogenesis and mutagenesis. Although a minute amount of capsaicin displays few or no deleterious effects, heavy ingestion of the compound has been associated with necrosis, ulceration and even carcinogenesis. Capsaicin is considered to be metabolized by cytochrome P-450-dependent mixed-function oxidases to reactive species. (A7835). An alkylamide found in CAPSICUM that acts at TRPV CATION CHANNELS.

4-Hydroxybenzyl alcohol

4-(Hydroxymethyl)phenol;p-Hydroxybenzyl alcohol;p-Methylolphenol

C7H8O2 (124.0524)


4-hydroxybenzyl alcohol is the cleavage product produced during the biosynthesis of the thiazole moiety of thiamine from tyrosine as part of the thiamine biosynthesis pathway. It is a derivative of benzyl alcohol which is used as a local anesthetic and to reduce pain associated with Lidocaine injection. Also, it is used in the manufacture of other benzyl compounds, as a pharmaceutical aid, and in perfumery and flavoring. Benzyl Alcohol is an aromatic alcohol used in a wide variety of cosmetic formulations as a fragrance component, preservative, solvent, and viscosity-decreasing agent. Benzyl Alcohol is metabolized to Benzoic Acid, which reacts with glycine and excreted as hippuric acid in the human body. Acceptable daily intakes were established by the World Health Organization at 5 mg/kg for Benzyl Alcohol. No adverse effects of benzyl alcohol have been seen in chronic exposure animal studies using rats and mice. Effects of Benzyl Alcohol in chronic exposure animal studies are limited to reduced feed intake and reduced growth. Some differences have been noted in one reproductive toxicity study using mice, but these were limited to lower maternal body weights and decreased mean litter weights. Another study also noted that fetal weight was decreased compared to controls, but a third study showed no differences between control and benzyl alcohol-treated groups. Benzyl Alcohol has been associated with an increased number of resorptions and malformations in hamsters, but there have been no reproductive or developmental toxicity findings in studies using mice and rats. Genotoxicity tests for benzyl alcohol are mostly negative, but there were some assays that were positive. Carcinogenicity studies, however, were negative. Clinical data indicates that benzyl alcohol can produce nonimmunologic contact urticaria and nonimmunologic immediate contact reactions, characterized by the appearance of wheals, erythema, and pruritis. 5\\\\% benzyl alcohol can elicit a reaction. Benzyl Alcohol is not a sensitizer at 10\\\\%. Benzyl Alcohol could be used safely at concentrations up to 5\\\\%, but that manufacturers should consider the nonimmunologic phenomena when using benzyl alcohol in cosmetic formulations designed for infants and children. Additionally, Benzyl Alcohol is considered safe up to 10\\\\% for use in hair dyes. The limited body exposure, the duration of use, and the frequency of use are considered in concluding that the nonimmunologic reactions would not be a concern. Because of the wide variety of product types in which benzyl alcohol may be used, it is likely that inhalation may be a route of exposure. The available safety tests are not considered sufficient to support the safety of benzyl alcohol in formulations where inhalation is a route of exposure. Inhalation toxicity data are needed to complete the safety assessment of benzyl alcohol where inhalation can occur. (PMID: 11766131). P-hydroxybenzyl alcohol is a member of the class of benzyl alcohols that is benzyl alcohol substituted by a hydroxy group at position 4. It has been isolated from Arcangelisia gusanlung.

3,4-Dihydroxybenzeneacetic acid

3,4-Dihydroxyphenylacetic Acid, Monosodium Salt

C8H8O4 (168.0423)


3,4-Dihydroxyphenylacetic acid (DOPAC) is a phenolic acid. DOPAC is a neuronal metabolite of dopamine (DA). DA undergoes monoamine oxidase-catalyzed oxidative deamination to 3,4-dihydroxyphenylacetaldehyde (DOPAL), which is metabolized primarily into DOPAC via aldehyde dehydrogenase (ALDH2). The biotransformation of DOPAL is critical as previous studies have demonstrated this DA-derived aldehyde to be a reactive electrophile and toxic to dopaminergic cells. Known inhibitors of mitochondrial ALDH2, such as 4-hydroxy-2-nonenal (4HNE) inhibit ALDH2-mediated oxidation of the endogenous neurotoxin DOPAL. 4HNE is one of the resulting products of oxidative stress, thus linking oxidative stress to the uncontrolled production of an endogenous neurotoxin relevant to Parkinsons disease. In early-onset Parkinson disease, there is markedly reduced activities of both monoamine oxidase (MAO) A and B. The amount of DOPAC, which is produced during dopamine oxidation by MAO, is greatly reduced as a result of increased parkin overexpression. Administration of methamphetamine to animals causes loss of DA terminals in the brain and significant decreases in dopamine and dihydroxyphenylacetic acid (DOPAC) in the striatum. Renal dopamine produced in the residual tubular units may be enhanced during a sodium challenge, thus behaving appropriately as a compensatory natriuretic hormone; however, the renal dopaminergic system in patients afflicted with renal parenchymal disorders should address parameters other than free urinary dopamine, namely the urinary excretion of L-DOPA and metabolites. DOPAC is one of the major phenolic acids formed during human microbial fermentation of tea, citrus, and soy flavonoid supplements. DOPAC exhibits a considerable antiproliferative effect in LNCaP prostate cancer and HCT116 colon cancer cells. The antiproliferative activity of DOPAC may be due to its catechol structure. A similar association of the catechol moiety in the B-ring with antiproliferative activity was demonstrated for flavanones (PMID:16956664, 16455660, 8561959, 11369822, 10443478, 16365058). DOPAC can be found in Gram-positive bacteria (PMID:24752840). 3,4-Dihydroxyphenylacetic acid (DOPAC) is a metabolite of the neurotransmitter dopamine. 3,4-Dihydroxyphenylacetic acid is found in many foods, some of which are alaska blueberry, cauliflower, ucuhuba, and fox grape. 3,4-Dihydroxybenzeneacetic acid is the main neuronal metabolite of dopamine.

L-Dopa

(2S)-2-Amino-3-(3,4-dihydroxyphenyl)-2-methylpropanoic acid

C9H11NO4 (197.0688)


L-dopa is an optically active form of dopa having L-configuration. Used to treat the stiffness, tremors, spasms, and poor muscle control of Parkinsons disease It has a role as a prodrug, a hapten, a neurotoxin, an antiparkinson drug, a dopaminergic agent, an antidyskinesia agent, an allelochemical, a plant growth retardant, a human metabolite, a mouse metabolite and a plant metabolite. It is a dopa, a L-tyrosine derivative and a non-proteinogenic L-alpha-amino acid. It is a conjugate acid of a L-dopa(1-). It is an enantiomer of a D-dopa. It is a tautomer of a L-dopa zwitterion. Levodopa is a prodrug of dopamine that is administered to patients with Parkinsons due to its ability to cross the blood-brain barrier. Levodopa can be metabolised to dopamine on either side of the blood-brain barrier and so it is generally administered with a dopa decarboxylase inhibitor like carbidopa to prevent metabolism until after it has crossed the blood-brain barrier. Once past the blood-brain barrier, levodopa is metabolized to dopamine and supplements the low endogenous levels of dopamine to treat symptoms of Parkinsons. The first developed drug product that was approved by the FDA was a levodopa and carbidopa combined product called Sinemet that was approved on May 2, 1975. 3,4-Dihydroxy-L-phenylalanine is a metabolite found in or produced by Escherichia coli (strain K12, MG1655). Levodopa is an Aromatic Amino Acid. Levodopa is an amino acid precursor of dopamine with antiparkinsonian properties. Levodopa is a prodrug that is converted to dopamine by DOPA decarboxylase and can cross the blood-brain barrier. When in the brain, levodopa is decarboxylated to dopamine and stimulates the dopaminergic receptors, thereby compensating for the depleted supply of endogenous dopamine seen in Parkinsons disease. To assure that adequate concentrations of levodopa reach the central nervous system, it is administered with carbidopa, a decarboxylase inhibitor that does not cross the blood-brain barrier, thereby diminishing the decarboxylation and inactivation of levodopa in peripheral tissues and increasing the delivery of dopamine to the CNS. L-Dopa is used for the treatment of Parkinsonian disorders and Dopa-Responsive Dystonia and is usually given with agents that inhibit its conversion to dopamine outside of the central nervous system. Peripheral tissue conversion may be the mechanism of the adverse effects of levodopa.

It is used for the treatment of PARKINSONIAN DISORDERS and is usually given with agents that inhibit its conversion to dopamine outside ... L-DOPA, also known as levodopa or 3,4-dihydroxyphenylalanine is an alpha amino acid. These are amino acids in which the amino group is attached to the carbon atom immediately adjacent to the carboxylate group (alpha carbon). L-DOPA is found naturally in both animals and plants. It is made via biosynthesis from the amino acid L-tyrosine by the enzyme tyrosine hydroxylase.. L-DOPA is the precursor to the neurotransmitters dopamine, norepinephrine (noradrenaline), and epinephrine (adrenaline), which are collectively known as catecholamines. The Swedish scientist Arvid Carlsson first showed in the 1950s that administering L-DOPA to animals with drug-induced (reserpine) Parkinsonian symptoms caused a reduction in the intensity of the animals symptoms. Unlike dopamine itself, L-DOPA can be taken orally and crosses the blood-brain barrier. It is rapidly taken up by dopaminergic neurons and converted to dopamine. In particular, it is metabolized to dopamine by aromatic L-amino acid decarboxylase. Pyridoxal phosphate (vitamin B6) is a required cofactor for this decarboxylation, and may be administered along with levodopa, usually as pyridoxine. As a result, L-DOPA is a drug that is now used for the treatment of Parkinsonian disorders and DOPA-Responsive Dystonia. It is usually given with agents that inhibit its conversion to dopamine outside of the central nervous system. It is standard clinical practice in treating Parkinsonism to co-administer a peripheral DOPA decarboxylase inhibitor - carbidopa or benserazide - and often a catechol-O-methyl transferase (COMT) inhibitor, to prevent synthesis of dopamine in peripheral tissue. Side effects of L-DOPA treatment may include: hypertension, arrhythmias, nausea, gastrointestinal bleeding, disturbed respiration, hair loss, disorientation and confusion. L-DOPA can act as an L-tyrosine mimetic and be incorporated into proteins by mammalian cells in place of L-tyrosine, generating protease-resistant and aggregate-prone proteins in vitro and may contribute to neurotoxicity with chronic L-DOPA administration. L-phenylalanine, L-tyrosine, and L-DOPA are all precursors to the biological pigment melanin. The enzyme tyrosinase catalyzes the oxidation of L-DOPA to the reactive intermediate dopaquinone, which reacts further, eventually leading to melanin oligomers.

Dopamine

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

C8H11NO2 (153.079)


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]

   

3,4-Dihydroxyphenylglycol

4-(1,2-dihydroxyethyl)benzene-1,2-diol

C8H10O4 (170.0579)


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.

   

N-Methyl-D-aspartic acid

(2R)-2-(methylamino)butanedioic acid

C5H9NO4 (147.0532)


N-Methyl-D-aspartic acid is an amino acid derivative acting as a specific agonist at the NMDA receptor, and therefore mimics the action of the neurotransmitter glutamate on that receptor. In contrast to glutamate, NMDA binds to and regulates the above receptor only, but not other glutamate receptors. NMDA is a water-soluble endogenous metabolite that plays an important role in the neuroendocrine system of species across Animalia (PMID:18096065). It was first synthesized in the 1960s (PMID:14056452). NMDA is an excitotoxin; this trait has applications in behavioural neuroscience research. The body of work utilizing this technique falls under the term "lesion studies." Researchers apply NMDA to specific regions of an (animal) subjects brain or spinal cord and subsequently test for the behaviour of interest, such as operant behaviour. If the behaviour is compromised, it suggests that the destroyed tissue was part of a brain region that made an important contribution to the normal expression of that behaviour. Examples of antagonists of the NMDA receptor are ketamine, amantadine, dextromethorphan (DXM), riluzole, and memantine. They are commonly referred to as NMDA receptor antagonists (PMID:28877137). N-Methyl-D-aspartic acid is an amino acid derivative acting as a specific agonist at the NMDA receptor, and therefore mimics the action of the neurotransmitter glutamate on that receptor.

Amitriptyline

dimethyl(3-{tricyclo[9.4.0.0³,⁸]pentadeca-1(15),3,5,7,11,13-hexaen-2-ylidene}propyl)amine

C20H23N (277.183)


Amitriptyline hydrochloride is a dibenzocycloheptene-derivative tricyclic antidepressant (TCA). TCAs are structurally similar to phenothiazines. They contain a tricyclic ring system with an alkyl amine substituent on the central ring. In non-depressed individuals, amitriptyline does not affect mood or arousal, but may cause sedation. In depressed individuals, amitriptyline exerts a positive effect on mood. TCAs are potent inhibitors of serotonin and norepinephrine reuptake. Tertiary amine TCAs, such as amitriptyline, are more potent inhibitors of serotonin reuptake than secondary amine TCAs, such as nortriptyline. TCAs also down-regulate cerebral cortical β-adrenergic receptors and sensitize post-synaptic serotonergic receptors with chronic use. The antidepressant effects of TCAs are thought to be due to an overall increase in serotonergic neurotransmission. TCAs also block histamine-H1 receptors, α1-adrenergic receptors and muscarinic receptors, which accounts for their sedative, hypotensive and anticholinergic effects (e.g. blurred vision, dry mouth, constipation, urinary retention), respectively. See toxicity section below for a complete listing of side effects. Amitriptyline may be used to treat depression, chronic pain (unlabeled use), irritable bowel syndrome (unlabeled use), diabetic neuropathy (unlabeled use), post-traumatic stress disorder (unlabeled use), and for migraine prophylaxis (unlabeled use).

Quinolinic acid

Pyridine-2,3-dicarboxylic acid

C7H5NO4 (167.0219)


Quinolinic acid, also known as quinolinate, belongs to the class of organic compounds known as pyridinecarboxylic acids. Pyridinecarboxylic acids are compounds containing a pyridine ring bearing a carboxylic acid group. It is also classified as a pyridine-2,3-dicarboxylic acid, which is a dicarboxylic acid with a pyridine backbone. Quinolinic acid is a colorless solid. In plants, it is the biosynthetic precursor to nicotine. Quinolinic acid is found in all organisms, from microbes to plants to animals. Quinolinic acid can be biosynthesized via aspartic acid in plants. Oxidation of aspartate by the enzyme aspartate oxidase gives iminosuccinate, containing the two carboxylic acid groups that are found in quinolinic acid. Condensation of iminosuccinate with glyceraldehyde-3-phosphate, mediated by quinolinate synthase, affords quinolinic acid Quinolinic acid is also a downstream product of the kynurenine pathway, which metabolizes the amino acid tryptophan ((PMID: 22678511). The kynurenine/tryptophan degradation pathway is important for its production of the coenzyme nicotinamide adenine dinucleotide (NAD+) and produces several neuroactive intermediates including quinolinic acid, kynurenine (KYN), kynurenic acid (KYNA), 3-hydroxykynurenine (3-HK), and 3-hydroxyanthranilic acid (3-HANA). In animals quinolinic acid acts as an NMDA receptor agonist and has a possible role in neurodegenerative disorders (PMID: 22678511). It also acts as a neurotoxin, gliotoxin, proinflammatory mediator, and pro-oxidant molecule (PMID: 22248144). Quinolinic acid can act as an endogenous brain excitotoxin when released by activated macrophages (PMID: 15013955). Within the brain, quinolinic acid is only produced by activated microglia and macrophages. Quinolinic acid is unable to pass through the blood-brain barrier (BBB) and must be produced within the brain by microglial cells or macrophages that have passed the BBB (PMID: 22248144). While quinolinic acid cannot pass through the BBB, kynurenic acid, tryptophan and 3-hydroxykynurenine can and can subsequently act as precursors to the production of quinolinic acid in the brain (PMID: 22248144). Quinolinic acid has potent neurotoxic effects. Studies have demonstrated that quinolinic acid may be involved in many psychiatric disorders and neurodegenerative diseases in the brain including ALS, Alzheimer’s disease, brain ischemia, Parkinson’s disease, Huntington’s disease and AIDS-dementia. Elevated CSF levels of quinolinic acid are correlated with the severity of neuropsychological deficits in patients who have AIDS. Indeed, levels of quinolinic acid in the CSF of AIDS patients suffering from AIDS-dementia can be up to twenty times higher than normal (PMID: 10936623). Quinolinic acid levels are increased in the brains of children infected with a range of bacterial infections of the central nervous system (CNS), of poliovirus patients, and of Lyme disease with CNS involvement patients. In addition, raised quinolinic acid levels have been found in traumatic CNS injury patients, patients suffering from cognitive decline with ageing, hyperammonaemia patients, hypoglycaemia patients, and systemic lupus erythematosus patients. Quinolinic acid has also been detected, but not quantified in, several different foods, such as Ceylon cinnamons, pitanga, Oregon yampahs, red bell peppers, and durians. This could make quinolinic acid a potential biomarker for the consumption of these foods. Quinolinic acid, also known as pyridine-2,3-dicarboxylate or 2,3-pyridinedicarboxylic acid, is a member of the class of compounds known as pyridinecarboxylic acids. Pyridinecarboxylic acids are compounds containing a pyridine ring bearing a carboxylic acid group. Quinolinic acid is slightly soluble (in water) and an extremely strong acidic compound (based on its pKa). Quinolinic acid can be found in a number of food items such as coconut, pistachio, chinese chives, and common bean, which makes quinolinic acid a potential biomarker for the consumption of these food products. Quinolinic acid can be found primarily in blood, cerebrospinal fluid (CSF), and urine, as well as throughout most human tissues. Quinolinic acid exists in all living species, ranging from bacteria to humans. In humans, quinolinic acid is involved in a couple of metabolic pathways, which include nicotinate and nicotinamide metabolism and tryptophan metabolism. Moreover, quinolinic acid is found to be associated with malaria, anemia, cNS tumors, and aIDS. Quinolinic acid has a potent neurotoxic effect. Studies have demonstrated that quinolinic acid may be involved in many psychiatric disorders, neurodegenerative processes in the brain, as well as other disorders. Within the brain, quinolinic acid is only produced by activated microglia and macrophages . Quinolinic acid. CAS Common Chemistry.

Thioguanine

2-Amino-1,7-dihydro-6H-purine-6-thione

C5H5N5S (167.0266)


Thioguanine is only found in individuals that have used or taken this drug. It is an antineoplastic compound which also has antimetabolite action. The drug is used in the therapy of acute leukemia. [PubChem]Thioguanine competes with hypoxanthine and guanine for the enzyme hypoxanthine-guanine phosphoribosyltransferase (HGPRTase) and is itself converted to 6-thioguanilyic acid (TGMP), which reaches high intracellular concentrations at therapeutic doses. TGMP interferes with the synthesis of guanine nucleotides by its inhibition of purine biosynthesis by pseudofeedback inhibition of glutamine-5-phosphoribosylpyrophosphate amidotransferase, the first enzyme unique to the de novo pathway of purine ribonucleotide synthesis. TGMP also inhibits the conversion of inosinic acid (IMP) to xanthylic acid (XMP) by competition for the enzyme IMP dehydrogenase. Thioguanine nucleotides are incorporated into both the DNA and the RNA by phosphodiester linkages, and some studies have shown that incorporation of such false bases contributes to the cytotoxicity of thioguanine. Its tumor inhibitory properties may be due to one or more of its effects on feedback inhibition of de novo purine synthesis; inhibition of purine nucleotide interconversions; or incorporation into the DNA and RNA. The overall result of its action is a sequential blockade of the utilization and synthesis of the purine nucleotides.

Oleamide is an amide of the fatty acid oleic acid. It is an endogenous substance: it occurs naturally in the body of animals. It accumulates in the cerebrospinal fluid during sleep deprivation and induces sleep in animals. It is being studied as a potential medical treatment for mood and sleep disorders, and cannabinoid-regulated depression. The mechanism of action of oleamides sleep inducing effects is an area of current research. It is likely that oleamide interacts with multiple neurotransmitter systems. Oleamide is structurally related to the endogenous cannabinoid anandamide, and has the ability to bind to the CB1 receptor as a full agonist. Oleamide. CAS Common Chemistry.

Rivastigmine

(S)-N-Ethyl-3-((1-dimethyl-amino)ethyl)-N-methylphenylcarbamate

C14H22N2O2 (250.1681)


Rivastigmine is only found in individuals that have used or taken this drug. It is a parasympathomimetic or cholinergic agent for the treatment of mild to moderate dementia of the Alzheimers type. Rivastigmine is a cholinesterase inhibitor that inhibits both butyrylcholinesterase and acetylcholinesterase.Rivastigmine is a carbamate derivative that is structurally related to physostigmine, but not to donepezil and tacrine. The precise mechanism of rivastigmine has not been fully determined, but it is suggested that rivastigmine binds reversibly with and inactivates chlolinesterase (eg. acetylcholinesterase, butyrylcholinesterase), preventing the hydrolysis of acetycholine, and thus leading to an increased concentration of acetylcholine at cholinergic synapses. The anticholinesterase activity of rivastigmine is relatively specific for brain acetylcholinesterase and butyrylcholinesterase compared with those in peripheral tissues.

Palmitoylethanolamide

N-(2-hydroxyethyl)hexadecanamide

C18H37NO2 (299.2824)


N-Palmitoylethanolamide (PEA) is present in the tissues of most mammals. It was initially described as an agonist of the type 2 cannabinoid receptor (CB2), although it is now universally recognized that PEA is in fact incapable of binding to cannabinoid receptors, or at least not to the known receptors. In addition to its anti-inflammatory activity, PEA also produces analgesia, neuroprotection, and possesses anti-epileptic properties. It also reduces gastrointestinal motility and cancer cell proliferation, as well as protecting the vascular endothelium in the ischemic heart. The physiological stimuli that regulate PEA levels in mammalian tissues are largely unknown, however, multiple studies indicate that this lipid accumulates during cellular stress, particularly following tissue injury. For example, PEA increases post-mortem in the pig brain. Similar elevations in PEA levels have been observed in the ischemic brain and PEA is also up-regulated in response to ultraviolet-B irradiation in mouse epidermal cells. Adipose tissue is highly implicated in the systemic secretion of IL-6 and leptin, and human mature adipocytes are able to secrete large quantity of PEA. Human adipose tissue can be subjected to modulation of its inflammatory state by lipopolysaccharide (LPS). LPS strongly inhibits adipose cell leptin release, with PEA acting as a potentiator of this inhibitory effect. These actions are not linked to a reduction in leptin gene transcription. Thus, PEA does not have an anti-inflammatory role in the secretion of IL-6 via NFkappaB at the adipocyte level, but instead seems to act at the heart of the LPS-stimulated pathway, which, independently of NFkappaB, inhibits the secretion of leptin.

C9H15N2O14P3 (467.9736)


Dutp, also known as 2-deoxyuridine 5-triphosphate or deoxy-utp, is a member of the class of compounds known as pyrimidine 2-deoxyribonucleoside triphosphates. Pyrimidine 2-deoxyribonucleoside triphosphates are pyrimidine nucleotides with a triphosphate group linked to the ribose moiety lacking a hydroxyl group at position 2. Dutp is slightly soluble (in water) and an extremely strong acidic compound (based on its pKa). Dutp can be found in a number of food items such as bilberry, japanese chestnut, black radish, and lovage, which makes dutp a potential biomarker for the consumption of these food products. Dutp can be found primarily in prostate Tissue, as well as throughout most human tissues. Dutp exists in all living species, ranging from bacteria to humans. In humans, dutp is involved in the pyrimidine metabolism. Dutp is also involved in few metabolic disorders, which include beta ureidopropionase deficiency, dihydropyrimidinase deficiency, MNGIE (mitochondrial neurogastrointestinal encephalopathy), and UMP synthase deficiency (orotic aciduria). Moreover, dutp is found to be associated with prostate cancer. Dutp is a non-carcinogenic (not listed by IARC) potentially toxic compound. Metabolism of organophosphates occurs principally by oxidation, by hydrolysis via esterases and by reaction with glutathione. Demethylation and glucuronidation may also occur. Oxidation of organophosphorus pesticides may result in moderately toxic products. In general, phosphorothioates are not directly toxic but require oxidative metabolism to the proximal toxin. The glutathione transferase reactions produce products that are, in most cases, of low toxicity. Paraoxonase (PON1) is a key enzyme in the metabolism of organophosphates. PON1 can inactivate some organophosphates through hydrolysis. PON1 hydrolyzes the active metabolites in several organophosphates insecticides as well as, nerve agents such as soman, sarin, and VX. The presence of PON1 polymorphisms causes there to be different enzyme levels and catalytic efficiency of this esterase, which in turn suggests that different individuals may be more susceptible to the toxic effect of organophosphate exposure (T3DB). Deoxyuridine triphosphate (dUTP) is a deoxynucleotide triphosphate (dNTP) that is chemically similar to uridine triphosphate (UTP) except that it has a deoxyribose sugar instead of a ribose sugar. DNA synthesis requires the availability of deoxynucleotide triphosphates (dTTP, dATP, dGTP, dCTP), whereas RNA synthesis requires the availability of nucleotide triphosphates (NTPs) such as TTP, ATP, GTP, and UTP. The conversion of nucleotide triphosphates (NTPs) into dNTPs can only be done in the diphosphate form. Typically, an NTP has one phosphate removed to become an NDP. This is then converted into a dNDP by an enzyme called ribonucleotide reductase and followed by the re-addition of phosphate to give a dNTP. dUTP is a substrate for several enzymes, including inosine triphosphate pyrophosphatase, deoxyuridine 5-triphosphate nucleotidohydrolase (mitochondrial), uridine-cytidine kinase 1, nucleoside diphosphate kinase 3, nucleoside diphosphate kinase B, nucleoside diphosphate kinase 6, nucleoside diphosphate kinase (mitochondrial), nucleoside diphosphate kinase homolog 5, nucleoside diphosphate kinase A, and nucleoside diphosphate kinase 7. While UTP is routinely incorporated into RNA, dUTP is not normally incorporated into DNA. Instead, if dUTP is misincorporated into DNA, it can cause DNA damage. Therefore, dUTP can be considered as a teratogen or a mutagen. The extent of DNA damage caused by dUTP is highly dependent on the levels of the dUTP pyrophosphatase (dUTPase) and uracil-DNA glycosylase (UDG), which limits the intracellular accumulation of dUTP. Additionally, loss of viability following thymidylate synthase (TS) inhibition occurs as a consequence of the accumulation of dUTP in some cell lines and subsequent misincorporation of uracil into DNA (PMID: 11487279).

Lipoamide

5-(1,2-Dithiolan-3-yl)-pentanamide

C8H15NOS2 (205.0595)


Lipoamide is a trivial name for 6,8-dithiooctanoic amide. It is 6,8-dithiooctanoic acids functional form where the carboxyl group is attached to protein (or any other amine) by an amide linkage (containing -NH2) to an amino group. Lipoamide forms a thioester bond, oxidizing the disulfide bond, with acetaldehyde (pyruvate after it has been decarboxylated). It then transfers the acetaldehyde group to CoA which can then continue in the TCA cycle. Lipoamide is an intermediate in glycolysis/gluconeogenesis, citrate cycle (TCA cycle), alanine, aspartate and pyruvate metabolism, and valine, leucine and isoleucine degradation (KEGG:C00248). It is generated from dihydrolipoamide via the enzyme dihydrolipoamide dehydrogenase (EC:1.8.1.4) and then converted to S-glutaryl-dihydrolipoamide via the enzyme oxoglutarate dehydrogenase (EC:1.2.4.2). Lipoamide is the oxidized form of glutathione. (PMID:8957191) KEIO_ID L031; [MS2] KO009031 KEIO_ID L031

Metyrosine is only found in individuals that have used or taken this drug. It is an inhibitor of the enzyme tyrosine 3-monooxygenase, and consequently of the synthesis of catecholamines. It is used to control the symptoms of excessive sympathetic stimulation in patients with pheochromocytoma. (Martindale, The Extra Pharmacopoeia, 30th ed)Metyrosine inhibits tyrosine hydroxylase, which catalyzes the first transformation in catecholamine biosynthesis, i.e., the conversion of tyrosine to dihydroxyphenylalanine (DOPA). Because the first step is also the rate-limiting step, blockade of tyrosine hydroxylase activity results in decreased endogenous levels of catecholamines and their synthesis. This consequently, depletes the levels of the catecholamines dopamine, adrenaline and noradrenaline in the body,usually measured as decreased urinary excretion of catecholamines and their metabolites. One main end result of the catecholamine depletion is a decrease in blood presure.

C26H37N5O2 (451.2947)


Cabergoline is only found in individuals that have used or taken this drug. It is a long-acting dopamine agonist and prolactin inhibitor. It is used to treat hyperprolactinemic disorders and Parkinsonian Syndrome. Cabergoline possesses potent agonist activity on dopamine D2 receptors. The dopamine D2 receptor is a 7-transmembrane G-protein coupled receptor associated with Gi proteins. In lactotrophs, stimulation of dopamine D2 causes inhibition of adenylyl cyclase, which decreases intracellular cAMP concentrations and blocks IP3-dependent release of Ca2+ from intracellular stores. Decreases in intracellular calcium levels may also be brought about via inhibition of calcium influx through voltage-gated calcium channels, rather than via inhibition of adenylyl cyclase. Additionally, receptor activation blocks phosphorylation of p42/p44 MAPK and decreases MAPK/ERK kinase phosphorylation. Inhibition of MAPK appears to be mediated by c-Raf and B-Raf-dependent inhibition of MAPK/ERK kinase. Dopamine-stimulated growth hormone release from the pituitary gland is mediated by a decrease in intracellular calcium influx through voltage-gated calcium channels rather than via adenylyl cyclase inhibition. Stimulation of dopamine D2 receptors in the nigrostriatal pathway leads to improvements in coordinated muscle activity in those with movement disorders.

Homovanillic acid (HVA)

4-Hydroxy-3-methoxyphenylacetic acid;Vanillacetic acid;2-(4-Hydroxy-3-methoxyphenyl)acetic acid

C9H10O4 (182.0579)


Homovanillic acid (HVA), also known as homovanillate, belongs to the class of organic compounds known as methoxyphenols. Methoxyphenols are compounds containing a methoxy group attached to the benzene ring of a phenol moiety. HVA is also classified as a catechol. HVA is a major catecholamine metabolite that is produced by a consecutive action of monoamine oxidase and catechol-O-methyltransferase on dopamine. HVA is typically elevated in patients with catecholamine-secreting tumors (such as neuroblastoma, pheochromocytoma, and other neural crest tumors). HVA levels are also used in monitoring patients who have been treated for these kinds tumors. HVA levels may also be altered in disorders of catecholamine metabolism such as monoamine oxidase-A (MOA) deficiency. MOA deficiency can cause decreased urinary HVA values, while a deficiency of dopamine beta-hydrolase (the enzyme that converts dopamine to norepinephrine) can cause elevated urinary HVA values. Within humans, HVA participates in a number of enzymatic reactions. In particular, HVA and pyrocatechol can be biosynthesized from 3,4-dihydroxybenzeneacetic acid and guaiacol. This reaction is catalyzed by the enzyme known as catechol O-methyltransferase. In addition, HVA can be biosynthesized from homovanillin through the action of the enzyme known aldehyde dehydrogenase. HVA has recently been found in a number of beers and appears to arise from the fermentation process (https://doi.org/10.1006/fstl.1999.0593). HVA is also a metabolite of Bifidobacterium (PMID: 24958563) and the bacterial breakdown of dietary flavonoids. Dietary flavonols commonly found in tomatoes, onions, and tea, can lead to significantly elevated levels of urinary HVA (PMID: 20933512). Likewise, the microbial digestion of hydroxytyrosol (found in olive oil) can also lead to elevated levels of HVA in humans (PMID: 11929304). Homovanillic acid is a monocarboxylic acid that is the 3-O-methyl ether of (3,4-dihydroxyphenyl)acetic acid. It is a catecholamine metabolite. It has a role as a human metabolite and a mouse metabolite. It is a member of guaiacols and a monocarboxylic acid. It is functionally related to a (3,4-dihydroxyphenyl)acetic acid. It is a conjugate acid of a homovanillate. Homovanillic acid is a natural product found in Aloe africana, Ginkgo biloba, and other organisms with data available. Homovanillic Acid is a monocarboxylic acid that is a catecholamine metabolite. Homovanillic acid may be used a marker for metabolic stress, tobacco usage or the presence of a catecholamine secreting tumor, such as neuroblastoma or pheochromocytoma. Homovanillic acid is a metabolite found in or produced by Saccharomyces cerevisiae. A 3-O-methyl ETHER of (3,4-dihydroxyphenyl)acetic acid. See also: Ipomoea aquatica leaf (part of). Homovanillic acid is a major catecholamine metabolite. 3-Methoxy-4-hydroxyphenylacetic acid is found in beer, olive, and avocado.

(R)-Salsolinol

1-Methyl-6,7-dihydroxy-1,2,3,4-tetrahydroisoquinoline

C10H13NO2 (179.0946)


Salsolinol is an endogenous catechol isoquinoline detected in humans. Salsolinol was detected in urine of parkinsonian patients administered with L-DOPA. This finding stimulated the studies on Salsolinol derivatives in the brain, and gave new aspects of the endogenous alkaloids, which had been considered to occur only in plants. In normal non-alcoholic subjects and alcoholics, Salsolinol and O-methylated Salsolinol were found in urine, cerebrospinal fluid and brains. Salsolinol has an asymmetric center at first position and exists as (R)- and (S)enantiomer. The (R)enantiomer of Salsolinol is predominant in urine from healthy volunteers. Only the (R)enantiomers of Salsolinol and N-methylated Salsolinol occur in the human brain, cerebrospinal fluid (CSF) and intraventricular fluid (IVF), and the (S)enantiomers were not detected. (R)salsolinol synthase catalyzes the enantio-selective synthesis of (R)Salsolinol and 1-carboxyl(R)Salsolinol from dopamine with acetaldehyde or pyruvic acid. The N-methylation of (R)salsolinol into N-methylsalsolinol (NMSal) is catalyzed by two N-methyltransferases with different optimum pH, at pH 7.0 and 8.4. NM(R)Salsolinol is enzymatically oxidized into 1,2-dimethyl-6,7-dihydroxyisoquinolinium ion (DMDHIQ+) by an oxidase sensitive to semicarbaside and also non-enzymatically by autoxidation. NM(R)Salsolinol and its precursor, dopamine, were found to occur selectively in the nigro-striatum, whereas (R)Salsolinol distributes uniformly among the brain regions. (PMID 14697894). Alkaloid from Annona reticulata (custard apple), Musa paradisiaca (banana) and Theobroma cacao (cocoa). xi-Salsolinol is found in cocoa and cocoa products and fruits.

C8H8O4 (168.0423)


3,4-Dihydroxyphenylacetic acid (DOPAC) is a phenolic acid. DOPAC is a neuronal metabolite of dopamine (DA). DA undergoes monoamine oxidase-catalyzed oxidative deamination to 3,4-dihydroxyphenylacetaldehyde (DOPAL), which is metabolized primarily into DOPAC via aldehyde dehydrogenase (ALDH2). The biotransformation of DOPAL is critical as previous studies have demonstrated this DA-derived aldehyde to be a reactive electrophile and toxic to dopaminergic cells. Known inhibitors of mitochondrial ALDH2, such as 4-hydroxy-2-nonenal (4HNE) inhibit ALDH2-mediated oxidation of the endogenous neurotoxin DOPAL. 4HNE is one of the resulting products of oxidative stress, thus linking oxidative stress to the uncontrolled production of an endogenous neurotoxin relevant to Parkinsons disease. In early-onset Parkinson disease, there is markedly reduced activities of both monoamine oxidase (MAO) A and B. The amount of DOPAC, which is produced during dopamine oxidation by MAO, is greatly reduced as a result of increased parkin overexpression. Administration of methamphetamine to animals causes loss of DA terminals in the brain and significant decreases in dopamine and dihydroxyphenylacetic acid (DOPAC) in the striatum. Renal dopamine produced in the residual tubular units may be enhanced during a sodium challenge, thus behaving appropriately as a compensatory natriuretic hormone; however, the renal dopaminergic system in patients afflicted with renal parenchymal disorders should address parameters other than free urinary dopamine, namely the urinary excretion of L-DOPA and metabolites. DOPAC is one of the major phenolic acids formed during human microbial fermentation of tea, citrus, and soy flavonoid supplements. DOPAC exhibits a considerable antiproliferative effect in LNCaP prostate cancer and HCT116 colon cancer cells. The antiproliferative activity of DOPAC may be due to its catechol structure. A similar association of the catechol moiety in the B-ring with antiproliferative activity was demonstrated for flavanones (PMID:16956664, 16455660, 8561959, 11369822, 10443478, 16365058). DOPAC can be found in Gram-positive bacteria (PMID:24752840). (3,4-dihydroxyphenyl)acetic acid is a dihydroxyphenylacetic acid having the two hydroxy substituents located at the 3- and 4-positions. It is a metabolite of dopamine. It has a role as a human metabolite. It is a dihydroxyphenylacetic acid and a member of catechols. It is functionally related to a phenylacetic acid. It is a conjugate acid of a (3,4-dihydroxyphenyl)acetate. 3,4-Dihydroxyphenylacetic acid is a natural product found in Liatris elegans, Tragopogon orientalis, and other organisms with data available. A deaminated metabolite of LEVODOPA. 3,4-Dihydroxyphenylacetic acid (DOPAC) is a metabolite of the neurotransmitter dopamine. 3,4-Dihydroxyphenylacetic acid is found in many foods, some of which are alaska blueberry, cauliflower, ucuhuba, and fox grape. 3,4-Dihydroxybenzeneacetic acid is the main neuronal metabolite of dopamine.

Salsolinol

6,7-Isoquinolinediol, 1,2,3,4-tetrahydro-1-methyl-, (S)-

C10H13NO2 (179.0946)


Salsolinol is an endogenous catechol isoquinoline detected in humans. Salsolinol was detected in urine of parkinsonian patients administered with L-DOPA. This finding stimulated the studies on Salsolinol derivatives in the brain, and gave new aspects of the endogenous alkaloids, which had been considered to occur only in plants. In normal non-alcoholic subjects and alcoholics, Salsolinol and O-methylated Salsolinol were found in urine, cerebrospinal fluid and brains. Salsolinol has an asymmetric center at first position and exists as (R)- and (S)enantiomer. The (R)enantiomer of Salsolinol is predominant in urine from healthy volunteers. Only the (R)enantiomers of Salsolinol and N-methylated Salsolinol occur in the human brain, cerebrospinal fluid (CSF) and intraventricular fluid (IVF), and the (S)enantiomers were not detected. (R)salsolinol synthase catalyzes the enantio-selective synthesis of (R)Salsolinol and 1-carboxyl(R)Salsolinol from dopamine with acetaldehyde or pyruvic acid. The N-methylation of (R)salsolinol into N-methylsalsolinol (NMSal) is catalyzed by two N-methyltransferases with different optimum pH, at pH 7.0 and 8.4. NM(R)Salsolinol is enzymatically oxidized into 1,2-dimethyl-6,7-dihydroxyisoquinolinium ion (DMDHIQ+) by an oxidase sensitive to semicarbaside and also non-enzymatically by autoxidation. NM(R)Salsolinol and its precursor, dopamine, were found to occur selectively in the nigro-striatum, whereas (R)Salsolinol distributes uniformly among the brain regions. (PMID 14697894) [HMDB].
