C10H13N5O4 (267.0967)


Adenosine is a ribonucleoside composed of a molecule of adenine attached to a ribofuranose moiety via a beta-N(9)-glycosidic bond. It has a role as an anti-arrhythmia drug, a vasodilator agent, an analgesic, a human metabolite and a fundamental metabolite. It is a purines D-ribonucleoside and a member of adenosines. It is functionally related to an adenine. The structure of adenosine was first described in 1931, though the vasodilating effects were not described in literature until the 1940s. Adenosine is indicated as an adjunct to thallium-201 in myocardial perfusion scintigraphy, though it is rarely used in this indication, having largely been replaced by [dipyridamole] and [regadenson]. Adenosine is also indicated in the treatment of supraventricular tachycardia. Adenosine was granted FDA approval on 30 October 1989. Adenosine is a metabolite found in or produced by Escherichia coli (strain K12, MG1655). Adenosine is an Adenosine Receptor Agonist. The mechanism of action of adenosine is as an Adenosine Receptor Agonist. Adenosine is a natural product found in Smilax bracteata, Mikania laevigata, and other organisms with data available. Adenosine is a ribonucleoside comprised of adenine bound to ribose, with vasodilatory, antiarrhythmic and analgesic activities. Phosphorylated forms of adenosine play roles in cellular energy transfer, signal transduction and the synthesis of RNA. Adenosine is a nucleoside that is composed of adenine and d-ribose. Adenosine or adenosine derivatives play many important biological roles in addition to being components of DNA and RNA. For instance, adenosine plays an important role in energy transfer - as adenosine triphosphate (ATP) and adenosine diphosphate (ADP). It also plays a role in signal transduction as cyclic adenosine monophosphate, cAMP. Adenosine itself is both a neurotransmitter and potent vasodilator. When administered intravenously, adenosine causes transient heart block in the AV node. Because of the effects of adenosine on AV node-dependent supraventricular tachycardia, adenosine is considered a class V antiarrhythmic agent. Adenosine is a metabolite found in or produced by Saccharomyces cerevisiae. A nucleoside that is composed of adenine and d-ribose. Adenosine or adenosine derivatives play many important biological roles in addition to being components of DNA and RNA. Adenosine itself is a neurotransmitter.

When administered intravenously adenosine causes transient heart block in the AV node. Due to the effects of adenosine on AV node-dependent supraventricular tachycardia, adenosine is considered a class V antiarrhythmic agent. Overdoses of adenosine intake (as a drug) can lead to several side effects including chest pain, feeling faint, shortness of breath, and tingling of the senses. Serious side effects include a worsening dysrhythmia and low blood pressure. When present in sufficiently high levels, adenosine can act as an immunotoxin and a metabotoxin. An immunotoxin disrupts, limits the function, or destroys immune cells. A metabotoxin is an endogenous metabolite that causes adverse health effects at chronically high levels. Chronically high levels of adenosine are associated with adenosine deaminase deficiency. Adenosine is a precursor to deoxyadenosine, which is a precursor to dATP. A buildup of dATP in cells inhibits ribonucleotide reductase and prevents DNA synthesis, so cells are unable to divide. Since developing T cells and B cells are some of the most mitotically active cells, they are unable to divide and propagate to respond to immune challenges. High levels of deoxyadenosine also lead to an increase in S-adenosylhomocysteine, which is toxic to immature lymphocytes. Adenosine is a nucleoside composed of a molecule of adenine attached to a ribose sugar molecule (ribofuranose) moiety via a beta-N9-glycosidic bond. [Wikipedia]. Adenosine is found in many foods, some of which are borage, japanese persimmon, nuts, and barley.

Inosine

9-[(2R,3R,4S,5R)-3,4-dihydroxy-5-(hydroxymethyl)oxolan-2-yl]-6,9-dihydro-3H-purin-6-one

C10H12N4O5 (268.0808)


Inosine, also known as hypoxanthosine or inotin, belongs to the class of organic compounds known as purine nucleosides. Purine nucleosides are compounds comprising a purine base attached to a ribosyl or deoxyribosyl moiety. Inosine is formed when hypoxanthine is attached to a ribose ring a beta-N9-glycosidic bond. Inosine is an intermediate in the degradation of purines and purine nucleosides to uric acid. Inosine is also an intermediate in the purine salvage pathway. Inosine occurs in the anticodon of certain transfer RNA molecules and is essential for proper translation of the genetic code in wobble base pairs. Inosine exists in all living species, ranging from bacteria to plants to humans. Inosine participates in a number of enzymatic reactions. In particular, inosine can be biosynthesized from inosinic acid through its interaction with the enzyme known as cytosolic purine 5-nucleotidase. In addition, inosine can be converted into hypoxanthine and ribose 1-phosphate through its interaction with the enzyme known as purine nucleoside phosphorylase. Altered levels of inosine have also been associated with purine nucleoside phosphorylase deficiency and xanthinuria type I, both of which are inborn errors of metabolism. Animal studies have suggested that inosine has neuroprotective properties. It has been proposed as a potential treatment for spinal cord injury (PMID: 16317421) and for administration after stroke, as inosine appears to induce axonal rewiring (PMID: 12084941). After ingestion, inosine is metabolized into uric acid, which has been found to be a natural antioxidant and peroxynitrite scavenger. As such, inosine may have potential benefits to patients with multiple sclerosis and Parkinson’s disease (PMID: 19425822). Inosine can also be produced by gut bacteria and appears to have a number of beneficial effects. Inosine, has been shown to activate peroxisome proliferator-activated receptor (PPAR)-gamma signaling in human colon epithelial cells. Furthermore, exogenous treatment of inosine has been found to protect against DSS-induced colitis in rodents by improving adenosine 2A receptor (A2AR)/PPAR-gamma-dependent mucosal barrier functions (PMID: 33820558). Microbiome-derived inosine has also been shown to modulate the response to checkpoint inhibitor immunotherapy in cancer models. In particular, decreased gut barrier function induced by immunotherapy increases systemic translocation of bacterially derived inosine and activates antitumor T cells. The effect of inosine is dependent on T cell expression of the adenosine A2A receptor and requires co-stimulation. Inosine appears to have other roles in non-mammalian system. For instance, it has been found to be an important feed stimulant by itself or in combination with certain amino acids in some species of farmed fish. For example, inosine and inosine-5-monophosphate have been reported as specific feeding stimulants for turbot fry, (Scophthalmus maximus) and Japanese amberjack. Inosine is a purine nucleoside in which hypoxanthine is attached to ribofuranose via a beta-N(9)-glycosidic bond. It has a role as a human metabolite, a Saccharomyces cerevisiae metabolite, an Escherichia coli metabolite and a mouse metabolite. It is a purines D-ribonucleoside and a member of inosines.

L-Proline

pyrrolidine-2-carboxylic acid

C5H9NO2 (115.0633)


Proline (Pro), also known as L-proline 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). Amino acids are organic compounds that contain amino (–NH2) and carboxyl (–COOH) functional groups, along with a side chain (R group) specific to each amino acid. Proline is one of 20 proteinogenic amino acids, i.e., the amino acids used in the biosynthesis of proteins. Proline is found in all organisms ranging from bacteria to plants to animals. It is classified as an aliphatic, non-polar amino acid. Proline is sometimes called an imino acid, although the IUPAC definition of an imine requires a carbon-nitrogen double bond. Proline is a non-essential amino acid that is synthesized from glutamic acid. It is an essential component of collagen and is important for proper functioning of joints and tendons. Proline is derived from the amino acid L-glutamate in which glutamate-5-semialdehyde is first formed by glutamate 5-kinase and glutamate-5-semialdehyde dehydrogenase (which requires NADH or NADPH). This semialdehyde can then either spontaneously cyclize to form 1-pyrroline-5-carboxylic acid, which is reduced to proline by pyrroline-5-carboxylate reductase, or turned into ornithine by ornithine aminotransferase, followed by cyclization by ornithine cyclodeaminase to form proline. L-Proline has been found to act as a weak agonist of the glycine receptor and of both NMDA and non-NMDA ionotropic glutamate receptors. It has been proposed to be a potential endogenous excitotoxin/neurotoxin. Studies in rats have shown that when injected into the brain, proline non-selectively destroys pyramidal and granule cells (PMID: 3409032 ). Therefore, under certain conditions proline can act as a neurotoxin and a metabotoxin. A neurotoxin causes damage to nerve cells and nerve tissues. A metabotoxin is an endogenously produced metabolite that causes adverse health effects at chronically high levels. Chronically high levels of proline are associated with at least five inborn errors of metabolism, including hyperprolinemia type I, hyperprolinemia type II, iminoglycinuria, prolinemia type II, and pyruvate carboxylase deficiency. People with hyperprolinemia type I often do not show any symptoms even though they have proline levels in their blood between 3 and 10 times the normal level. Some individuals with hyperprolinemia type I exhibit seizures, intellectual disability, or other neurological or psychiatric problems. Hyperprolinemia type II results in proline levels in the blood between 10 and 15 times higher than normal, and high levels of a related compound called pyrroline-5-carboxylate. Hyperprolinemia type II has signs and symptoms that vary in severity and is more likely than type I to involve seizures or intellectual disability. L-proline is pyrrolidine in which the pro-S hydrogen at position 2 is substituted by a carboxylic acid group. L-Proline is the only one of the twenty DNA-encoded amino acids which has a secondary amino group alpha to the carboxyl group. It is an essential component of collagen and is important for proper functioning of joints and tendons. It also helps maintain and strengthen heart muscles. It has a role as a micronutrient, a nutraceutical, an algal metabolite, a Saccharomyces cerevisiae metabolite, an Escherichia coli metabolite, a mouse metabolite and a member of compatible osmolytes. It is a glutamine family amino acid, a proteinogenic amino acid, a proline and a L-alpha-amino acid. It is a conjugate base of a L-prolinium. It is a conjugate acid of a L-prolinate. It is an enantiomer of a D-proline. It is a tautomer of a L-proline zwitterion. Proline is one of the twenty amino acids used in living organisms as the building blocks of proteins.

Proline is a non-essential amino acid that is synthesized from glutamic acid. It is an essential component of collagen and is important for proper functioning of joints and tendons. L-Proline is a metabolite found in or produced by Escherichia coli (strain K12, MG1655). Proline is a cyclic, nonessential amino acid (actually, an imino acid) in humans (synthesized from glutamic acid and other amino acids), Proline is a constituent of many proteins. Found in high concentrations in collagen, proline constitutes almost a third of the residues.

C5H9NO4 (147.0532)


Glutamic acid (Glu), also known as L-glutamic acid or as glutamate, the name of its anion, 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). Amino acids are organic compounds that contain amino (‚ÄìNH2) and carboxyl (‚ÄìCOOH) functional groups, along with a side chain (R group) specific to each amino acid. L-glutamic acid is one of 20 proteinogenic amino acids, i.e., the amino acids used in the biosynthesis of proteins. Glutamic acid is found in all organisms ranging from bacteria to plants to animals. It is classified as an acidic, charged (at physiological pH), aliphatic amino acid. In humans it is a non-essential amino acid and can be synthesized via alanine or aspartic acid via alpha-ketoglutarate and the action of various transaminases. Glutamate also plays an important role in the bodys disposal of excess or waste nitrogen. Glutamate undergoes deamination, an oxidative reaction catalysed by glutamate dehydrogenase leading to alpha-ketoglutarate. In many respects glutamate is a key molecule in cellular metabolism. Glutamate is the most abundant fast excitatory neurotransmitter in the mammalian nervous system. At chemical synapses, glutamate is stored in vesicles. Nerve impulses trigger release of glutamate from the pre-synaptic cell. In the opposing post-synaptic cell, glutamate receptors, such as the NMDA receptor, bind glutamate and are activated. Because of its role in synaptic plasticity, it is believed that glutamic acid is involved in cognitive functions like learning and memory in the brain. Glutamate transporters are found in neuronal and glial membranes. They rapidly remove glutamate from the extracellular space. In brain injury or disease, they can work in reverse and excess glutamate can accumulate outside cells. This process causes calcium ions to enter cells via NMDA receptor channels, leading to neuronal damage and eventual cell death, and is called excitotoxicity. The mechanisms of cell death include: Damage to mitochondria from excessively high intracellular Ca2+. Glu/Ca2+-mediated promotion of transcription factors for pro-apoptotic genes, or downregulation of transcription factors for anti-apoptotic genes. Excitotoxicity due to glutamate occurs as part of the ischemic cascade and is associated with stroke and diseases like amyotrophic lateral sclerosis, lathyrism, and Alzheimers disease. Glutamic acid has been implicated in epileptic seizures. Microinjection of glutamic acid into neurons produces spontaneous depolarization around one second apart, and this firing pattern is similar to what is known as paroxysmal depolarizing shift in epileptic attacks. This change in the resting membrane potential at seizure foci could cause spontaneous opening of voltage activated calcium channels, leading to glutamic acid release and further depolarization (http://en.wikipedia.org/wiki/Glutamic_acid). Glutamate was discovered in 1866 when it was extracted from wheat gluten (from where it got its name. Glutamate has an important role as a food additive and food flavoring agent. In 1908, Japanese researcher Kikunae Ikeda identified brown crystals left behind after the evaporation of a large amount of kombu broth (a Japanese soup) as glutamic acid. These crystals, when tasted, reproduced a salty, savory flavor detected in many foods, most especially in seaweed. Professor Ikeda termed this flavor umami. He then patented a method of mass-producing a crystalline salt of glutamic acid, monosodium glutamate. L-glutamic acid is an optically active form of glutamic acid having L-configuration. It has a role as a nutraceutical, a micronutrient, an Escherichia coli metabolite, a mouse metabolite, a ferroptosis inducer and a neurotransmitter. It is a glutamine family amino acid, a proteinogenic amino acid, a glutamic acid and a L-alpha-amino acid. It is a conjugate acid of a L-glutamate(1-). It is an enantiomer of a D-glutamic acid. A peptide that is a homopolymer of glutamic acid. L-Glutamic acid is a metabolite found in or produced by Escherichia coli (strain K12, MG1655). Glutamic acid (Glu), also referred to as glutamate (the anion), is one of the 20 proteinogenic amino acids. It is not among the essential amino acids. Glutamate is a key molecule in cellular metabolism. In humans, dietary proteins are broken down by digestion into amino acids, which serves as metabolic fuel or other functional roles in the body. Glutamate is the most abundant fast excitatory neurotransmitter in the mammalian nervous system. At chemical synapses, glutamate is stored in vesicles. Nerve impulses trigger release of glutamate from the pre-synaptic cell. In the opposing post-synaptic cell, glutamate receptors, such as the NMDA receptor, bind glutamate and are activated. Because of its role in synaptic plasticity, it is believed that glutamic acid is involved in cognitive functions like learning and memory in the brain. Glutamate transporters are found in neuronal and glial membranes. They rapidly remove glutamate from the extracellular space. In brain injury or disease, they can work in reverse and excess glutamate can accumulate outside cells. This process causes calcium ions to enter cells via NMDA receptor channels, leading to neuronal damage and eventual cell death, and is called excitotoxicity. The mechanisms of cell death include: * Damage to mitochondria from excessively high intracellular Ca2+. * Glu/Ca2+-mediated promotion of transcription factors for pro-apoptotic genes, or downregulation of transcription factors for anti-apoptotic genes. Excitotoxicity due to glutamate occurs as part of the ischemic cascade and is associated with stroke and diseases like amyotrophic lateral sclerosis, lathyrism, and Alzheimers disease. glutamic acid has been implicated in epileptic seizures. Microinjection of glutamic acid into neurons produces spontaneous depolarization around one second apart, and this firing pattern is similar to what is known as paroxysmal depolarizing shift in epileptic attacks. This change in the resting membrane potential at seizure foci could cause spontaneous opening of voltage activated calcium channels, leading to glutamic acid release and further depolarization. A non-essential amino acid naturally occurring in the L-form. Glutamic acid is the most common excitatory neurotransmitter in the CENTRAL NERVOUS SYSTEM.

Since 1965 the industrial source of glutamic acid for MSG production has been bacterial fermentation of carbohydrate sources such as molasses and corn starch hydrolysate in the presence of a nitrogen source such as ammonium salts or urea. Annual production approx. 350000t worldwide in 1988. Seasoning additive in food manuf. (as Na, K and NH4 salts). Dietary supplement, nutrient Glutamic acid (symbol Glu or E;[4] the anionic form is known as glutamate) is an α-amino acid that is used by almost all living beings in the biosynthesis of proteins. It is a non-essential nutrient for humans, meaning that the human body can synthesize enough for its use. It is also the most abundant excitatory neurotransmitter in the vertebrate nervous system. It serves as the precursor for the synthesis of the inhibitory gamma-aminobutyric acid (GABA) in GABAergic neurons. Its molecular formula is C 5H 9NO 4. Glutamic acid exists in two optically isomeric forms; the dextrorotatory l-form is usually obtained by hydrolysis of gluten or from the waste waters of beet-sugar manufacture or by fermentation.[5][full citation needed] Its molecular structure could be idealized as HOOC−CH(NH 2)−(CH 2)2−COOH, with two carboxyl groups −COOH and one amino group −NH 2. However, in the solid state and mildly acidic water solutions, the molecule assumes an electrically neutral zwitterion structure −OOC−CH(NH+ 3)−(CH 2)2−COOH. It is encoded by the codons GAA or GAG. The acid can lose one proton from its second carboxyl group to form the conjugate base, the singly-negative anion glutamate −OOC−CH(NH+ 3)−(CH 2)2−COO−. This form of the compound is prevalent in neutral solutions. The glutamate neurotransmitter plays the principal role in neural activation.[6] This anion creates the savory umami flavor of foods and is found in glutamate flavorings such as MSG. In Europe, it is classified as food additive E620. In highly alkaline solutions the doubly negative anion −OOC−CH(NH 2)−(CH 2)2−COO− prevails. The radical corresponding to glutamate is called glutamyl. The one-letter symbol E for glutamate was assigned in alphabetical sequence to D for aspartate, being larger by one methylene –CH2– group.[7] DL-Glutamic acid is the conjugate acid of Glutamic acid, which acts as a fundamental metabolite. Comparing with the second phase of polymorphs α and β L-Glutamic acid, DL-Glutamic acid presents better stability[1].

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).

Spermine

(3-aminopropyl)({4-[(3-aminopropyl)amino]butyl})amine

C10H26N4 (202.2157)


Spermine, also known as gerontine or musculamine, belongs to the class of organic compounds known as dialkylamines. These are organic compounds containing a dialkylamine group, characterized by two alkyl groups bonded to the amino nitrogen. The resultin N-carbamoylputrescine is acted on by a hydrolase to split off urea group, leaving putrescine. The precursor for synthesis of spermine is the amino acid ornithine. The intermediate is spermidine. Spermine is a drug. Spermine exists in all living species, ranging from bacteria to humans. 5-methylthioadenosine and spermine can be biosynthesized from S-adenosylmethioninamine and spermidine through its interaction with the enzyme spermine synthase. Another pathway in plants starts with decarboxylation of L-arginine to produce agmatine. In humans, spermine is involved in spermidine and spermine biosynthesis. Outside of the human body, spermine is found, on average, in the highest concentration in oats. Spermine has also been detected, but not quantified in several different foods, such as sapodilla, mexican groundcherries, cloves, sourdocks, and sunflowers. This could make spermine a potential biomarker for the consumption of these foods. This decarboxylation gives putrescine. The name spermin was first used by the German chemists Ladenburg and Abel in 1888, and the correct structure of spermine was not finally established until 1926, simultaneously in England (by Dudley, Rosenheim, and Starling) and Germany (by Wrede et al.). In one pathway L-glutamine is the precursor to L-ornithine, after which the synthesis of spermine from L-ornithine follows the same pathway as in animals. Spermine is a potentially toxic compound. [Spectral] Spermine (exact mass = 202.21575) and Spermidine (exact mass = 145.1579) were not completely separated on HPLC under the present analytical conditions as described in AC$XXX.

Topiramate

[(3aS,5aR,8aR,8bS)-2,2,7,7-tetramethyl-5,5a,8a,8b-tetrahydrodi[1,3]dioxolo[4,5-a:5,3-d]pyran-3a-yl]methyl sulfamate

C12H21NO8S (339.0988)


Topiramate is an anticonvulsant drug used to treat epilepsy in both children and adults. In children it is also indicated for treatment of Lennox-Gastaut syndrome (a disorder that causes seizures and developmental delays). It is also Food and Drug Administration (FDA) approved, and now most frequently prescribed for, the prevention of migraines. It has been used by psychiatrists to treat bipolar disorder, although it is not FDA approved for this purpose and such use is somewhat controversial. This drug has been investigated for use in treatment of obesity, especially to aid in the reduction of binge eating, and also as a possible treatment for alcoholism. However, these uses are not actively promoted by the manufacturer, and like its use for bipolar disorder, are off-label uses. The drug is also used in clinical trials to treat Post Traumatic Stress Disorder. A pilot study suggests that Topiramate is possibly effective against infantile spasm; Chemically, topiramate is a sulfamate-substituted monosaccharide, related to fructose, a rather unusual chemical structure for an anticonvulsant. Topiramate is quickly absorbed after oral use. Most of the drug (70\\\%) is excreted in the urine as unchanged drug. The remainder is extensively metabolized by hydroxylation, hydrolysis, and glucuronidation. Six metabolites have been identified in humans, none of which constitutes more than 5\\\% of an administered dose. Topiramate enhances GABA-activated chloride channels. In addition, topiramate inhibits excitatory neurotransmission, through actions on kainate and AMPA receptors. There is evidence that topiramate has a specific effect on GluR5 kainate receptors. It is also an inhibitor of carbonic anhydrase, particularly subtypes II and IV, but this action is weak and unlikely to be related to its anticonvulsant actions, but may account for the bad taste and the development of renal stones seen during treatment. Its possible effect as a mood stabilizer seems to occur before anticonvulsant qualities at lower dosages. Topiramate inhibits maximal electroshock and pentylenetetrazol-induced seizures as well as partial and secondarily generalized tonic-clonic seizures in the kindling model, findings predictive of a broad spectrum of antiseizure activities clinically; Johnson.

Glycerol 3-phosphate

alpha-Glycerophosphoric acid, 1,2,3-propanetriol-1-(18)O,3-(dihydrogen phosphate)-labeled

C3H9O6P (172.0137)


Glycerol 3-phosphate, also known as glycerophosphoric acid or alpha-glycerophosphorate, is a member of the class of compounds known as glycerophosphates. Glycerophosphates are compounds containing a glycerol linked to a phosphate group. Glycerol 3-phosphate is soluble (in water) and a moderately acidic compound (based on its pKa). Glycerol 3-phosphate can be found in a number of food items such as sacred lotus, common oregano, mixed nuts, and yautia, which makes glycerol 3-phosphate a potential biomarker for the consumption of these food products. Glycerol 3-phosphate can be found primarily in blood, feces, saliva, and urine, as well as in human prostate tissue. Glycerol 3-phosphate exists in all living species, ranging from bacteria to humans. In humans, glycerol 3-phosphate is involved in several metabolic pathways, some of which include cardiolipin biosynthesis cl(i-12:0/i-21:0/a-21:0/i-21:0), cardiolipin biosynthesis cl(i-12:0/a-25:0/i-13:0/i-12:0), cardiolipin biosynthesis cl(i-13:0/i-21:0/i-21:0/a-25:0), and cardiolipin biosynthesis cl(i-13:0/a-25:0/i-18:0/a-13:0). Glycerol 3-phosphate is also involved in several metabolic disorders, some of which include de novo triacylglycerol biosynthesis tg(i-24:0/19:0/16:0), de novo triacylglycerol biosynthesis TG(16:0/22:4(7Z,10Z,13Z,16Z)/16:1(9Z)), de novo triacylglycerol biosynthesis TG(18:0/18:3(9Z,12Z,15Z)/14:1(9Z)), and de novo triacylglycerol biosynthesis TG(18:3(6Z,9Z,12Z)/22:5(4Z,7Z,10Z,13Z,16Z)/20:2(11Z,14Z)). Glycerol 3-phosphate is a chemical intermediate in the glycolysis metabolic pathway. It is commonly confused with the similarly named glycerate 3-phosphate or glyceraldehyde 3-phosphate. Glycerol 3-phosphate is produced from glycerol, the triose sugar backbone of triglycerides and glycerophospholipids, by the enzyme glycerol kinase. Glycerol 3-phospate may then be converted by dehydrogenation to dihydroxyacetone phosphate (DHAP) by the enzyme glycerol-3-phosphate dehydrogenase. DHAP can then be rearranged into glyceraldehyde 3-phosphate (GA3P) by triose phosphate isomerase (TIM), and feed into glycolysis. The glycerol 3-phosphate shuttle is used to rapidly regenerate NAD+ in the brain and skeletal muscle cells of mammals (wikipedia).

It is a weakly alkaline compound and can therefore combine with acidic compounds to form white salts or powders (which is how it is typically sold and consumed). Cocaine is a strong stimulant that is most frequently used as a recreational drug. It is the second most frequently used illegal drug globally, after cannabis. The stimulant and hunger suppression properties of cocaine and coca leaf extracts have been known for thousands of years by indigenous groups in central and South America. The coca leaf was, and still is, chewed almost universally by some indigenous communities. Cocaine acts by inhibiting the reuptake of serotonin, norepinephrine, and dopamine. This inhibition leads to a number of mental and physical effects that may include loss of contact with reality, an intense feeling of happiness, periods of agitation, along with a rapid heart rate, sweating, and dialated pupils. Cocaine is highly addictive due to its effect on the reward pathway in the brain (PMID: 22856655). Cocaine addiction occurs through overexpression of the FosB protein in the nucleus accumbens of the brain, which results in altered transcriptional regulation in neurons within the nucleus accumbens. Cocaine is harmful. Its use increases the risk of stroke, myocardial infarction, lung problems (in those who smoke it), blood infections, and sudden cardiac death. Medically, cocaine is infrequently used as a local anesthetic and vasoconstrictor to cause loss of feeling or numbness before certain medical procedures (e.g., biopsy, stitches, wound cleaning) (PMID: 28956316). Topical cocaine is occasionally used as a local numbing agent to help with painful procedures in the mouth or nose. Cocaine is now predominantly used for nasal and lacrimal duct surgery. It works quickly to numb certain areas of the body (e.g., nose, ear, or throat) about 1-2 minutes after application. Cocaine functions as an anesthesia by reversibly binding to and inactivating sodium channels, thereby inhibiting excitation of nerve endings or by blocking conduction in peripheral nerves. Cocaine and its major metabolites are only found in individuals that have used or taken this drug.

γ-Aminobutyric acid

gamma-Aminobutyric acid, calcium salt (2:1)

C4H9NO2 (103.0633)


gamma-Aminobutyric acid (GABA) is an inhibitory neurotransmitter found in the nervous systems of widely divergent species, including humans. It is the chief inhibitory neurotransmitter in the vertebrate central nervous system. In vertebrates, GABA acts at inhibitory synapses in the brain. It acts by binding to specific transmembrane receptors in the plasma membrane of both pre- and postsynaptic neurons. This binding causes the opening of ion channels to allow either the flow of negatively-charged chloride ions into the cell or positively-charged potassium ions out of the cell. This will typically result in a negative change in the transmembrane potential, usually causing hyperpolarization. Three general classes of GABA receptor are known (PMID: 10561820). These include GABA-A and GABA-C ionotropic receptors, which are ion channels themselves, and GABA-B metabotropic receptors, which are G protein-coupled receptors that open ion channels via intermediaries known as G proteins (PMID: 10561820). Activation of the GABA-B receptor by GABA causes neuronal membrane hyperpolarization and a resultant inhibition of neurotransmitter release. In addition to binding sites for GABA, the GABA-A receptor has binding sites for benzodiazepines, barbiturates, and neurosteroids. GABA-A receptors are coupled to chloride ion channels. Therefore, activation of the GABA-A receptor induces increased inward chloride ion flux, resulting in membrane hyperpolarization and neuronal inhibition (PMID: 10561820). After release into the synapse, free GABA that does not bind to either the GABA-A or GABA-B receptor complexes can be taken up by neurons and glial cells. Four different GABA membrane transporter proteins (GAT-1, GAT-2, GAT-3, and BGT-1), which differ in their distribution in the CNS, are believed to mediate the uptake of synaptic GABA into neurons and glial cells. The GABA-A receptor subtype regulates neuronal excitability and rapid changes in fear arousal, such as anxiety, panic, and the acute stress response (PMID: 10561820). Drugs that stimulate GABA-A receptors, such as the benzodiazepines and barbiturates, have anxiolytic and anti-seizure effects via GABA-A-mediated reduction of neuronal excitability, which effectively raises the seizure threshold. GABA-A antagonists produce convulsions in animals and there is decreased GABA-A receptor binding in a positron emission tomography (PET) study of patients with panic disorder. Neurons that produce GABA as their output are called GABAergic neurons and have chiefly inhibitory action at receptors in the vertebrate. Medium spiny neurons (MSNs) are a typical example of inhibitory CNS GABAergic cells. GABA has been shown to have excitatory roles in the vertebrate, most notably in the developing cortex. Organisms synthesize GABA from glutamate using the enzyme L-glutamic acid decarboxylase and pyridoxal phosphate as a cofactor (PMID: 12467378). It is worth noting that this involves converting the principal excitatory neurotransmitter (glutamate) into the principal inhibitory one (GABA). Drugs that act as agonists of GABA receptors (known as GABA analogs or GABAergic drugs), or increase the available amount of GABA typically have relaxing, anti-anxiety, and anti-convulsive effects. GABA is found to be deficient in cerebrospinal fluid and the brain in many studies of experimental and human epilepsy. Benzodiazepines (such as Valium) are useful in status epilepticus because they act on GABA receptors. GABA increases in the brain after administration of many seizure medications. Hence, GABA is clearly an antiepileptic nutrient. Inhibitors of GAM metabolism can also produce convulsions. Spasticity and involuntary movement syndromes, such as Parkinsons, Friedreichs ataxia, tardive dyskinesia, and Huntingtons chorea, are all marked by low GABA when amino acid levels are studied. Trials of 2 to 3 g of GABA given orally have been effective in various epilepsy and spasticity syndromes. Agents that elevate GABA are als... Gamma-aminobutyric acid, also known as gaba or 4-aminobutanoic acid, belongs to gamma amino acids and derivatives class of compounds. Those are amino acids having a (-NH2) group attached to the gamma carbon atom. Thus, gamma-aminobutyric acid is considered to be a fatty acid lipid molecule. Gamma-aminobutyric acid is soluble (in water) and a weakly acidic compound (based on its pKa). Gamma-aminobutyric acid can be synthesized from butyric acid. Gamma-aminobutyric acid is also a parent compound for other transformation products, including but not limited to, (1S,2S,5S)-2-(4-glutaridylbenzyl)-5-phenylcyclohexan-1-ol, 4-(methylamino)butyric acid, and pregabalin. Gamma-aminobutyric acid can be found in a number of food items such as watercress, sour cherry, peach, and cardoon, which makes gamma-aminobutyric acid a potential biomarker for the consumption of these food products. Gamma-aminobutyric acid can be found primarily in most biofluids, including urine, cerebrospinal fluid (CSF), blood, and feces, as well as throughout most human tissues. Gamma-aminobutyric acid exists in all living species, ranging from bacteria to humans. In humans, gamma-aminobutyric acid is involved in a couple of metabolic pathways, which include glutamate metabolism and homocarnosinosis. Gamma-aminobutyric acid is also involved in few metabolic disorders, which include 2-hydroxyglutric aciduria (D and L form), 4-hydroxybutyric aciduria/succinic semialdehyde dehydrogenase deficiency, hyperinsulinism-hyperammonemia syndrome, and succinic semialdehyde dehydrogenase deficiency. Moreover, gamma-aminobutyric acid is found to be associated with alzheimers disease, hyper beta-alaninemia, tuberculous meningitis, and hepatic encephalopathy. Gamma-aminobutyric acid is a non-carcinogenic (not listed by IARC) potentially toxic compound. gamma-Aminobutyric acid (γ-Aminobutyric acid) (GABA ) is the chief inhibitory neurotransmitter in the mammalian central nervous system. Its principal role is reducing neuronal excitability throughout the nervous system. In humans, GABA is also directly responsible for the regulation of muscle tone . Chronically high levels of GABA are associated with at least 5 inborn errors of metabolism including: D-2-Hydroxyglutaric Aciduria, 4-Hydroxybutyric Aciduria/Succinic Semialdehyde Dehydrogenase Deficiency, GABA-Transaminase Deficiency, Homocarnosinosis and Succinic semialdehyde dehydrogenase deficiency (T3DB).

Tetrahydrocannabinol

(6aR,10aR)-6,6,9-trimethyl-3-pentyl-6H,6aH,7H,8H,10aH-benzo[c]isochromen-1-ol

C21H30O2 (314.2246)


Tetrahydrocannabinol, abbreviated THC, is a cannabinoid identified in cannabis and is its principal psychoactive constituent. First isolated in 1964, in its pure form, it is a glassy solid when cold, and becomes viscous and sticky if warmed. Synthetically prepared THC, officially referred to by its INN, dronabinol, is available by prescription in the U.S. and Canada under the brand name Marinol. The mechanism of action of THC is not completely understood. It is thought that cannabinoid receptors in neural tissues may mediate the effects of cannabinoids. Animal studies suggest that Marinols antiemetic effects may be due to inhibition of the vomiting control mechanism in the medulla oblongata. A literature review on the subject concluded that "Cannabis use appears to be neither a sufficient nor a necessary cause for psychosis. It is a component cause, part of a complex constellation of factors leading to psychosis." Likewise, a French review from 2009 came to a conclusion that cannabis use, particularly that before age 15, was a factor in the development of schizophrenic disorders. An aromatic terpenoid, THC has a very low solubility in water, but good solubility in most organic solvents, specifically lipids and alcohols. The presence of these specialized cannabinoid receptors in the brain led researchers to the discovery of endocannabinoids, such as anandamide and 2-arachidonoyl glyceride (2-AG). THC targets receptors in a manner far less selective than endocannabinoid molecules released during retrograde signalling, as the drug has a relatively low cannabinoid receptor efficacy and affinity. In populations of low cannabinoid receptor density, THC may act to antagonize endogenous agonists that possess greater receptor efficacy. THC is a lipophilic molecule and may bind non-specifically to a variety of receptors in the brain and body, such as adipose tissue. Dronabinol is only found in individuals that have used or taken this drug. It is extracted from the resin of Cannabis sativa (marijuana, hashish). The isomer delta-9-tetrahydrocannabinol is considered the most active form, producing the characteristic mood and perceptual changes associated with this compound. In the United States, Marinol has been rescheduled from Schedule II to Schedule III of the Controlled Substances Act in 1999, reflecting a finding that THC had a potential for abuse less than that of cocaine and heroin. As a Schedule III drug, it is available by prescription and is considered to be non-narcotic and to have a low risk of physical or mental dependence. Marinol has been approved by the U.S. Food and Drug Administration (FDA) in the treatment of anorexia in AIDS patients, as well as for refractory nausea and vomiting of patients undergoing chemotherapy, which has raised much controversy as to why natural THC is still a Schedule I drug. Efforts to get cannabis rescheduled as analogous to Marinol have not succeeded thus far. In April 2005, Canadian authorities approved the marketing of Sativex, a mouth spray for multiple sclerosis patients, who can use it to alleviate neuropathic pain and spasticity. Sativex contains tetrahydrocannabinol together with cannabidiol and is a preparation of whole cannabis rather than individual cannabinoids. It is marketed in Canada by GW Pharmaceuticals, being the first cannabis-based prescription drug in the world (in modern times). In addition, Sativex received European regulatory approval in 2010. An analog of dronabinol, nabilone, is available commercially in Canada under the trade name Cesamet, manufactured by Valeant Pharmaceuticals. Cesamet has also received FDA approval and began marketing in the U.S. in 2006. It is a Schedule II drug. Δ9tetrahydrocannabinol, also known as delta(9)-thc or marinol, is a member of the class of compounds known as 2,2-dimethyl-1-benzopyrans. 2,2-dimethyl-1-benzopyrans are organic compounds containing a 1-benzopyran moiety that carries two methyl groups at the 2-position. Δ9tetrahydrocannabinol is practically insoluble (in water) and a very weakly acidic compound (based on its pKa). Δ9tetrahydrocannabinol can be found in a number of food items such as wakame, cloves, burbot, and black cabbage, which makes Δ9tetrahydrocannabinol a potential biomarker for the consumption of these food products. Δ9tetrahydrocannabinol can be found primarily in blood and urine. Δ9tetrahydrocannabinol is a non-carcinogenic (not listed by IARC) potentially toxic compound. Δ9tetrahydrocannabinol is a drug which is used for the treatment of anorexia associated with weight loss in patients with aids, and nausea and vomiting associated with cancer chemotherapy in patients who have failed to respond adequately to conventional antiemetic treatment. The mechanism of action of marinol is not completely understood. It is thought that cannabinoid receptors in neural tissues may mediate the effects of dronabinol and other cannabinoids. Animal studies with other cannabinoids suggest that marinols antiemetic effects may be due to inhibition of the vomiting control mechanism in the medulla oblongata (DrugBank). A potentially serious oral ingestion, if recent, should be managed with gut decontamination. In unconscious patients with a secure airway, instill activated charcoal (30 to 100 g in adults, 1 to 2 g/kg in infants) via a nasogastric tube. A saline cathartic or sorbitol may be added to the first dose of activated charcoal. Patients experiencing depressive, hallucinatory or psychotic reactions should be placed in a quiet area and offered reassurance. Benzodiazepines (5 to 10 mg diazepam po) may be used for treatment of extreme agitation. Hypotension usually responds to Trendelenburg position and IV fluids. Pressors are rarely required (L1712) (T3DB).

C14H16ClN3O4S2 (389.0271)


As a diuretic, cyclothiazide inhibits active chloride reabsorption at the early distal tubule via the Na-Cl cotransporter, resulting in an increase in the excretion of sodium, chloride, and water. Thiazides like cyclothiazide also inhibit sodium ion transport across the renal tubular epithelium through binding to the thiazide sensitive sodium-chloride transporter. This results in an increase in potassium excretion via the sodium-potassium exchange mechanism. The antihypertensive mechanism of cyclothiazide is less well understood although it may be mediated through its action on carbonic anhydrases in the smooth muscle or through its action on the large-conductance calcium-activated potassium (KCa) channel, also found in the smooth muscle. Cyclothiazide is indicated as adjunctive therapy in edema associated with congestive heart failure, hepatic cirrhosis, and corticosteroid and estrogen therapy. It is also indicated in the management of hypertension either as the sole therapeutic agent or to enhance the effectiveness of other antihypertensive drugs in the more severe forms of hypertension.

C5H9NO4 (147.0532)


DL-Glutamate, also known as E or DL-glutamic acid, belongs to the class of organic compounds known as glutamic acid and derivatives. Glutamic acid and derivatives are compounds containing glutamic acid or a derivative thereof resulting from reaction of glutamic acid at the amino group or the carboxy group, or from the replacement of any hydrogen of glycine by a heteroatom. These are amino acids in which the amino group is attached to the carbon atom immediately adjacent to the carboxylate group (alpha carbon). DL-Glutamate exists in all living organisms, ranging from bacteria to humans. DL-Glutamate is found, on average, in the highest concentration within a few different foods, such as red bell peppers, milk (cow), and wheats and in a lower concentration in eggplants, romaine lettuces, and nanking cherries. DL-Glutamate has also been detected, but not quantified, in a few different foods, such as apples, broccoli, and lettuces. Glutamic acid (abbreviated as Glu or E) is one of the 20 proteinogenic amino acids. It is a non-essential amino acid. Glutamic acid is found in many foods, some of which are garden onion, orange bell pepper, oat, and cucumber.

C21H32O5S (396.197)


Pregnenolone sulfate is a sulfated version of the steroid hormone known as pregnenolone. Pregnenolone sulfate belongs to the class of organic compounds known as sulfated steroids. These are sterol lipids containing a sulfate group attached to the steroid skeleton. Pregnenolone sulfate is a neurosteroid found in the brain and central nervous system. Pregnenolone sulfate is a metabolite synthesized from pregnenolone via sulfation. It is known to have cognitive and memory-enhancing, antidepressant, anxiogenic, and proconvulsant effects (PMID: 21094889). As a neurosteroid, pregnenolone sulfate modulates a variety of ion channels, transporters, and enzymes. Interestingly, as a sulfated steroid, pregnenolone sulfate is not the final- or waste-product of pregnenolone being sulfated via a phase II metabolism reaction and renally excreted, as one would presume from pharmacology textbook knowledge. Pregnenolone sulfate is also the source and thereby the starting point for subsequent steroid synthesis pathways. Recently, pregnenolone sulfate has been shown to not only be a modulator of ion channels, but it is also an activating ion channel ligand (PMID: 24084011). Pregnenolone sulfate, a neurosteroid, is a metabolite of Pregnenolone. It is found in the brain and central nervous system.
