5-Methoxytryptamine, also known as mexamine or 5-MT, belongs to the class of organic compounds known as tryptamines and derivatives. Tryptamines and derivatives are compounds containing the tryptamine backbone, which is structurally characterized by an indole ring substituted at the 3-position by an ethanamine. It is biosynthesized via the deacetylation of melatonin in the pineal gland. 5-MT acts as a full agonist at the 5-HT1, 5-HT2, 5-HT4, 5-HT6, and 5-HT7 receptors. 5-Methoxytryptamine exists in all living organisms, ranging from bacteria to humans. Its affinity for the 5-HT5A receptor is unknown. It has no affinity for the 5-HT3 receptor and is affinity for the 5-HT1E receptor is very weak in comparison to the other 5-HT1 receptors. 5-MT has been shown to occur naturally in the body in low levels. Serotonin derivative proposed as potentiator for hypnotics and sedatives. [HMDB] KEIO_ID M040

Galactosylsphingosine

(2R,3R,4S,5R,6R)-2-{[(4E)-2-amino-3-hydroxyoctadec-4-en-1-yl]oxy}-6-(hydroxymethyl)oxane-3,4,5-triol

C24H47NO7 (461.3352)

Galactosylsphingosine (also known as psychosine), is an intermediate in the biosynthesis of cerebrosides. It is formed from the reaction of sphingosine with UDP-galactose and then reacts with fatty acid-coenzyme A to form the cerebroside. It is a galactoside metabolite of sphingosine and can function as a neurotoxin and a metabotoxin. A neurotoxin is a compound that disrupts or attacks neural cells and neural tissue. A metabotoxin is an endogenously produced metabolite that causes adverse health effects at chronically high levels. Chronically high levels of galactosylsphingosine are associated with globoid cell leukodystrophy (Krabbe disease), which is characterized by the dysfunction of galactosylceramidase. Galactosylsphingosine is a highly cytotoxic lipid capable of inducing cell death in a wide variety of cell types including oligodendrocytes. It is known to accumulate in the nervous system in the absence of galactosylceramidase. Galactosylsphingosine localizes to lipid rafts and perturbs membrane integrity. It also inhibits protein kinase C translocation to the plasma membrane (PMID: 24006512). Symptoms of Krabbe disease begin between the ages of 3 and 6 months with irritability, fevers, limb stiffness, seizures, feeding difficulties, vomiting, and slowing of mental and motor development. In the first stages of the disease, the symptoms are often mistaken with those of cerebral palsy. Other symptoms include muscle weakness, spasticity, deafness, optic atrophy, optic nerve enlargement, blindness, paralysis, and difficulty when swallowing. An intermediate in the biosynthesis of cerebrosides. It is formed by reaction of sphingosine with UDP-galactose and then itself reacts with fatty acid-Coenzyme A to form the cerebroside.

Bufotenin

3-(2-(Dimethylamino)ethyl)-1H-indol-5-ol (acd/name 4.0)

C12H16N2O (204.1263)

A hallucinogenic serotonin analog found in frog or toad skins, mushrooms, higher plants, and mammals, especially in the brains, plasma, and urine of schizophrenics. Bufotenin has been used as a tool in CNS studies and misused as a psychedelic. Bufotenin (5-OH-DMT), is a tryptamine related to the neurotransmitter serotonin. It is an alkaloid found in the skin of some species of toads; in mushrooms, higher plants, and mammals. Bufotenin is a chemical constituent in the venom and eggs of several species of toads belonging to the Bufo genus, but most notably in the Colorado River toad (Bufo alvarius) as it is the only toad species in which bufotenin is present in large enough quantities for a psychoactive effect. Extracts of toad venom, containing bufotenin and other bioactive compounds, have been used in some traditional medicines (probably derived from Bufo gargarizans), which has been used medicinally for centuries in China. Bufotenin is a constituent of the seeds of Anadenanthera colubrina and Anadenanthera peregrina trees. Anadenanthera seeds have been used as an ingredient in psychedelic snuff preparations by indigenous cultures of the Caribbean, Central and South America.

C21H31N5O2 (385.2478)

Buspirone is only found in individuals that have used or taken this drug. It is an anxiolytic agent and a serotonin receptor agonist belonging to the azaspirodecanedione class of compounds. Its structure is unrelated to those of the benzodiazepines, but it has an efficacy comparable to diazepam. [PubChem]Buspirone binds to 5-HT type 1A serotonin receptors on presynaptic neurons in the dorsal raphe and on postsynaptic neurons in the hippocampus, thus inhibiting the firing rate of 5-HT-containing neurons in the dorsal raphe. Buspirone also binds at dopamine type 2 (DA2) receptors, blocking presynaptic dopamine receptors. Buspirone increases firing in the locus ceruleus, an area of brain where norepinephrine cell bodies are found in high concentration. The net result of buspirone actions is that serotonergic activity is suppressed while noradrenergic and dopaminergic cell firing is enhanced.

C10H15N5O11P2 (443.0243)

Guanosine diphosphate, also known as gdp or 5-diphosphate, guanosine, is a member of the class of compounds known as purine ribonucleoside diphosphates. Purine ribonucleoside diphosphates are purine ribobucleotides with diphosphate group linked to the ribose moiety. Guanosine diphosphate is slightly soluble (in water) and a moderately acidic compound (based on its pKa). Guanosine diphosphate can be found in a number of food items such as strawberry, onion-family vegetables, walnut, and scarlet bean, which makes guanosine diphosphate a potential biomarker for the consumption of these food products. Guanosine diphosphate can be found primarily in blood and cerebrospinal fluid (CSF). Guanosine diphosphate exists in all living species, ranging from bacteria to humans. In humans, guanosine diphosphate is involved in several metabolic pathways, some of which include betahistine h1-antihistamine action, fexofenadine h1-antihistamine action, clocinizine h1-antihistamine action, and bepotastine h1-antihistamine action. Guanosine diphosphate is also involved in several metabolic disorders, some of which include adenine phosphoribosyltransferase deficiency (APRT), canavan disease, gout or kelley-seegmiller syndrome, and pyruvate dehydrogenase complex deficiency. Moreover, guanosine diphosphate is found to be associated with epilepsy, subarachnoid hemorrhage, neuroinfection, and stroke. Guanosine diphosphate, abbreviated GDP, is a nucleoside diphosphate. It is an ester of pyrophosphoric acid with the nucleoside guanosine. GDP consists of the pyrophosphate group, the pentose sugar ribose, and the nucleobase guanine . Guanosine diphosphate, also known as 5-GDP or 5-diphosphate, guanosine, belongs to the class of organic compounds known as purine ribonucleoside diphosphates. These are purine ribobucleotides with diphosphate group linked to the ribose moiety. Guanosine diphosphate exists in all living species, ranging from bacteria to humans. In humans, guanosine diphosphate is involved in intracellular signalling through adenosine receptor A2B and adenosine. Outside of the human body, Guanosine diphosphate has been detected, but not quantified in several different foods, such as devilfish, java plums, green beans, almonds, and orange mints. Guanosine diphosphate is a purine ribonucleoside 5-diphosphate resulting from the formal condensation of the hydroxy group at the 5 position of guanosine with pyrophosphoric acid.

Guanosine triphosphate

({[({[(2R,3S,4R,5R)-5-(2-amino-6-oxo-6,9-dihydro-1H-purin-9-yl)-3,4-dihydroxyoxolan-2-yl]methoxy}(hydroxy)phosphoryl)oxy](hydroxy)phosphoryl}oxy)phosphonic acid

C10H16N5O14P3 (522.9907)

Guanosine-5-triphosphate (GTP) is a purine nucleoside triphosphate. It is one of the building blocks needed for the synthesis of RNA during the transcription process. Its structure is similar to that of the guanosine nucleoside, the only difference being that nucleotides like GTP have phosphates on their ribose sugar. GTP has the guanine nucleobase attached to the 1 carbon of the ribose and it has the triphosphate moiety attached to riboses 5 carbon. GTP is essential to signal transduction, in particular with G-proteins, in second-messenger mechanisms where it is converted to guanosine diphosphate (GDP) through the action of GTPases. Guanosine triphosphate, also known as 5-GTP or H4GTP, belongs to the class of organic compounds known as purine ribonucleoside triphosphates. These are purine ribonucleotides with a triphosphate group linked to the ribose moiety. Thus, a GTP-bound tubulin serves as a cap at the tip of microtubule to protect from depolymerization; and, once the GTP is hydrolyzed, the microtubule begins to depolymerize and shrink rapidly. Guanosine triphosphate exists in all living species, ranging from bacteria to humans. In humans, guanosine triphosphate is involved in intracellular signalling through adenosine receptor A2B and adenosine. Guanosine-5-triphosphate (GTP) is a purine nucleoside triphosphate. Outside of the human body, guanosine triphosphate has been detected, but not quantified in several different foods, such as mandarin orange (clementine, tangerine), coconuts, new zealand spinachs, sweet marjorams, and pepper (capsicum). Cyclic guanosine triphosphate (cGTP) helps cyclic adenosine monophosphate (cAMP) activate cyclic nucleotide-gated ion channels in the olfactory system. It also has the role of a source of energy or an activator of substrates in metabolic reactions, like that of ATP, but more specific. It is used as a source of energy for protein synthesis and gluconeogenesis. For instance, a GTP molecule is generated by one of the enzymes in the citric acid cycle. GTP is also used as an energy source for the translocation of the ribosome towards the 3 end of the mRNA. During microtubule polymerization, each heterodimer formed by an alpha and a beta tubulin molecule carries two GTP molecules, and the GTP is hydrolyzed to GDP when the tubulin dimers are added to the plus end of the growing microtubule. The importing of these proteins plays an important role in several pathways regulated within the mitochondria organelle, such as converting oxaloacetate to phosphoenolpyruvate (PEP) in gluconeogenesis. GTP is involved in energy transfer within the cell. Guanosine triphosphate (GTP) is a guanine nucleotide containing three phosphate groups esterified to the sugar moiety. GTP functions as a carrier of phosphates and pyrophosphates involved in channeling chemical energy into specific biosynthetic pathways. GTP activates the signal transducing G proteins which are involved in various cellular processes including proliferation, differentiation, and activation of several intracellular kinase cascades. Proliferation and apoptosis are regulated in part by the hydrolysis of GTP by small GTPases Ras and Rho. Another type of small GTPase, Rab, plays a role in the docking and fusion of vesicles and may also be involved in vesicle formation. In addition to its role in signal transduction, GTP also serves as an energy-rich precursor of mononucleotide units in the enzymatic biosynthesis of DNA and RNA. [HMDB]. Guanosine triphosphate is found in many foods, some of which are oat, star fruit, lingonberry, and linden.

2-Deoxyinosine triphosphate (dITP) is a deoxyribonucleotide that may be generated from dATP by slow, non-enzymatic hydrolysis or by reduction of ITP. Normally, the cellular dITP concentration is very low. The inability to demonstrate the synthesis of dITP in cellular preparations has been attributed to the presence in the cytoplasm of an inosine triphosphatase pyrophosphatase (ITPase, EC 3.6.1.19), an enzyme that does not permit accumulation of these nucleotides. dITP can be incorporated into DNA by polymerases. The deoxyribonucleotide dITP behaves as a dGTP analogue and is incorporated opposite cytosine with about 50\\% efficiency. Both isolated nuclei and purified DNA polymerases rapidly incorporated dITP into DNA. In the presence of ATP, dITP is stabilized in extracts of nuclei. dITP exist in all cells and is potentially mutagenic, and the levels of these nucleotides are controlled by ITPase. The function of this ubiquitous protein family is proposed to be the elimination of minor potentially mutagenic or clastogenic purine nucleoside triphosphates from the cell.

C20H34O5 (354.2406)

Prostaglandin E1 (PGE1) is a potent endogenous vasodilator agent that increases peripheral blood flow. It inhibits platelet aggregation and has many other biological effects such as bronchodilation, mediation of inflammation, and various protective functions. The protective action of PGE1 has been shown on both experimental animal models of liver injury and patients with fulminant viral hepatitis. PGE1-treated cirrhotic rats had less hepatosplenomegaly, lower serum alanine aminotransferase levels and portal pressures, and higher arterial pressure than placebo-treated cirrhotic rats. There are several mechanisms of PGE1 hepatic cytoprotection: inhibiting T-cell mediated cytotoxicity, enhancing DNA synthesis of the injured liver after partial hepatectomy by stimulating cyclic AMP production, increasing ATP level in hepatic tissue to accelerate the recovery of mitochondrial respiratory function after reperfusion, and stabilizing membrane microviscosity. PGE1 is a prostanoid. The term prostanoid collectively describes prostaglandins, prostacyclins, and thromboxanes. Prostanoids are a subclass of the lipid mediator group known as eicosanoids. They are derived from C-20 polyunsaturated fatty acids, mainly dihomo-γ-linolenic (20:3n-6), arachidonic (20:4n-6), and eicosapentaenoic (20:5n-3) acids, through the action of cyclooxygenases-1 and -2 (COX-1 and COX-2) (PMID: 11819590, 16986207). Prostaglandins are eicosanoids. The eicosanoids consist of the prostaglandins (PGs), thromboxanes (TXs), leukotrienes (LTs), and lipoxins (LXs). The PGs and TXs are collectively identified as prostanoids. Prostaglandins were originally shown to be synthesized in the prostate gland, thromboxanes from platelets (thrombocytes), and leukotrienes from leukocytes, hence the derivation of their names. All mammalian cells except erythrocytes synthesize eicosanoids. These molecules are extremely potent and are able to cause profound physiological effects at very dilute concentrations. All eicosanoids function locally at the site of synthesis through receptor-mediated G-protein linked signalling pathways. Prostaglandin E1 (Alprostadil) is a prostanoid receptor ligand, with Kis of 1.1 nM, 2.1 nM, 10 nM, 33 nM and 36 nM for mouse EP3, EP4, EP2, IP and EP1, respectively. Prostaglandin E1 induces vasodilation and inhibits platelet aggregation. Prostaglandin E1 can be used as a vasodilator for the research of peripheral vascular diseases[1][2][3].

It has also been used to decrease urinary obstruction and relieve symptoms associated with symptomatic benign prostatic hyperplasia. α₁-Receptors mediate contraction and hypertrophic growth of smooth muscle cells. Antagonism of these receptors leads to smooth muscle relaxation in the peripheral vasculature and prostate gland. Prazosin has also been used in conjunction with cardiac glycosides and diuretics in the management of severe congestive heart failure. It has also been used alone or in combination with β-blockers in the preoperative management of signs and symptoms of pheochromocytoma.

Target: Adrenergic Receptor Prazosin, is a sympatholytic drug used to treat high blood pressure and anxiety, PTSD, andpanic disorder. It is an alpha-adrenergic blocker that is specific for the alpha-1 receptors. These receptors are found on vascular smooth muscle, where they are responsible for the vasoconstrictive action of norepinephrine. They are also found throughout the central nervous system. As of 2013, prazosin is off-patent in the US, and the FDA has approved at least one generic manufacturer.In addition to its alpha-blocking activity, prazosin is an antagonist of the MT3 receptor (which is not present in humans), with selectivity for this receptor over the MT1 and MT2 receptors. Prazosin is orally active and has a minimal effect on cardiac function due to its alpha-1 receptor selectivity. However, when prazosin is initially started, heart rate and contractility go up in order to maintain the pre-treatment blood pressures because the body has reached homeostasis at its abnormally high blood pressure. The blood pressure lowering effect becomes apparent when prazosin is taken for longer periods of time. The heart rate and contractility go back down over time and blood pressure decreases.

Dimethyltryptamine

N-(2-(1H-indol-3-yl)Ethyl)-N,N-dimethylamine (acd/name 4.0)

C12H16N2 (188.1313)

An N-methylated indoleamine derivative, a serotonergic hallucinogen found in several plants, especially Prestonia amazonica (Apocynaceae) and in mammalian brain, blood, and urine. It apparently acts as an agonist at some types of serotonin receptors and an antagonist at others.; DMT is a derivative of tryptamine with two additional methyl groups at the amine nitrogen atom. DMT is often synthesized by the Speeter-Anthony synthesis from indole using oxalyl chloride, dimethylamine, and lithium aluminium hydride as reagents. DMT is usually used in its base form, but it is more stable as a salt, e.g. as a fumarate. In contrast to DMTs base, its salts are water-soluble. DMT in solution degrades relatively fast and should be stored protected from air and light in a freezer. Highly pure DMT crystals, when evaporated out of a solvent and depositing upon glass, often produce small but highly defined white crystalline needles which when viewed under intense light will sparkle, and appear colorless under high magnification. In labs, it has been known to be explosive under a certain degree of heat.; DMT is a powerful psychoactive substance. If DMT is smoked, injected, or orally ingested with an MAOI, it can produce powerful entheogenic experiences including intense visual hallucinations, euphoria, even true hallucinations (perceived extensions of reality). A trip sitter is recommended to assist the drug user in staying physically and mentally healthy, and, in the case of smoked DMT, to catch the pipe if the user loses awareness of it.; DMT is classified in the United States as a Schedule I drug. In December of 2004, the Supreme Court lifted a stay thereby allowing the Brazil-based Uniaeo do Vegetal (UDV) church to use a decoction containing DMT in their Christmas services that year. This decoction is a tea made from boiled leaves and vines, known as hoasca within the UDV, and ayahuasca in different cultures. In Gonzales v. O Centro EspArita Beneficente Uniaeo do Vegetal, the Supreme Court heard arguments on November 1, 2005 and unanimously ruled in February 2006 that the U.S. federal government must allow the UDV to import and consume the tea for religious ceremonies under the 1993 Religious Freedom Restoration Act. There are no drug tests that would show DMT usage. None of the basic NIDA 5 drug tests or any extended drug test will show a result for DMT.; Dimethyltryptamine (DMT), also known as N,N-dimethyltryptamine, is a psychedelic tryptamine. It is not to be confused with 5-MeO-DMT and is similar in chemical structure to the neurotransmitter serotonin. DMT is created in small amounts by the human body during normal metabolism by the enzyme tryptamine-N-methyltransferase. Pure DMT at room temperature is a clear or white crystalline solid. DMT was first chemically synthesized in 1931. It also occurs naturally in many species of plants. DMT-containing plants are used in several South American shamanic practices. It is one of the main active constituents of snuffs like yopo and of the drink ayahuasca.; Oral ingestion: DMT, which is broken down by the digestive enzyme monoamine oxidase, is practically inactive if taken orally, unless combined with a monoamine oxidase inhibitor (MAOI). The traditional South American ayahuasca, or yage, is a tea mixture containing DMT and a MAOI. There are a number of admixtures to this brew, but most commonly it is simply the leaves of Psychotria viridis (containing DMT), and the vine Banisteriopsis caapi (the source of MAOI). Other DMT containing plants, including Diplopterys cabrerana, are sometimes used in ayahuasca in different areas of South America. Two common sources in the western US are Reed canary grass (Phalaris arundinacea) and Harding grass (Phalaris aquatica). These invasive grasses contain low levels of DMT and other alkaloids.

MAOIs should be used with extreme caution as they can have lethal complications with some prescription drugs, such as SSRI antidepressants, and some over-the-counter drugs. Smoked: If DMT is smoked, the maximal effects last for a short period of time (5-30 minutes dose dependent). The onset after inhalation is very fast (less than 45 seconds) and maximal effects are reached within about a minute. The Business Mans lunch trip is a common name due to the relatively short duration of vaporized, insufflated, or injected DMT.

C17H17N3O6S2 (423.0559)

Cephapirin is an injectable, first-generation cephalosporin antibiotic that has a wide spectrum of activity against gram-positive and gram-negative organisms. The bactericidal activity of cephapirin results from the inhibition of cell wall synthesis via affinity for penicillin-binding proteins (PBPs). Cephapirin is more resistant to beta-lactamases than the penicillins, and therefore is effective against staphylococci, with the exception of methicillin-resistant staphylococci. Cephapirin is FDA approved for use in food-producing animals, especially dairy cattle. Cephapirin is used for the treatment of mastitis in cows. Production for use in humans has been discontinued in the United States. It is marketed under the trade name Cefadyl. Active against gram-positive and -negative bacteria (vet. use). FDA approved for use in food producing animals, especies dairy cattle.

Isoproterenol is only found in individuals that have used or taken this drug. It is an isopropyl analog of epinephrine; beta-sympathomimetic that acts on the heart, bronchi, skeletal muscle, alimentary tract, etc. It is used mainly as bronchodilator and heart stimulant. [PubChem]The pharmacologic effects of isoproterenol are at least in part attributable to stimulation through beta-adrenergic receptors of intracellular adenyl cyclase, the enzyme that catalyzes the conversion of adenosine triphosphate (ATP) to cyclic AMP. Increased cyclic AMP levels are associated with relaxation of bronchial smooth muscle and inhibition of release of mediators of immediate hypersensitivity from cells, especially from mast cells.

Cyclizine

(N-Benzhydryl)(n-methyl)diethylenediamine

C18H22N2 (266.1783)

Cyclizine is only found in individuals that have used or taken this drug. It is a histamine H1 antagonist given by mouth or parenterally for the control of postoperative and drug-induced vomiting and in motion sickness. (From Martindale, The Extra Pharmacopoeia, 30th ed, p935)Vomiting (emesis) is essentially a protective mechanism for removing irritant or otherwise harmful substances from the upper GI tract. Emesis or vomiting is controlled by the vomiting centre in the medulla region of the brain, an important part of which is the chemotrigger zone (CTZ). The vomiting centre possesses neurons which are rich in muscarinic cholinergic and histamine containing synapses. These types of neurons are especially involved in transmission from the vestibular apparatus to the vomiting centre. Motion sickness principally involves overstimulation of these pathways due to various sensory stimuli. Hence the action of cyclizine which acts to block the histamine receptors in the vomiting centre and thus reduce activity along these pathways. Furthermore since cyclizine possesses anti-cholinergic properties as well, the muscarinic receptors are similarly blocked.

Pindolol is only found in individuals that have used or taken this drug. It is a moderately lipophilic beta blocker (adrenergic beta-antagonists). It is non-cardioselective and has intrinsic sympathomimetic actions, but little membrane-stabilizing activity. (From Martindale, The Extra Pharmocopoeia, 30th ed, p638)Pindolol non-selectively blocks beta-1 adrenergic receptors mainly in the heart, inhibiting the effects of epinephrine and norepinephrine resulting in a decrease in heart rate and blood pressure. By binding beta-2 receptors in the juxtaglomerular apparatus, Pindolol inhibits the production of renin, thereby inhibiting angiotensin II and aldosterone production and therefore inhibits the vasoconstriction and water retention due to angiotensin II and aldosterone, respectively.

C10H12N5O6P (329.0525)

Cyclic amp, also known as camp or adenosine 3,5-cyclic monophosphate, is a member of the class of compounds known as 3,5-cyclic purine nucleotides. 3,5-cyclic purine nucleotides are purine nucleotides in which the oxygen atoms linked to the C3 and C5 carbon atoms of the ribose moiety are both bonded the same phosphorus atom of the phosphate group. Cyclic amp is slightly soluble (in water) and a moderately acidic compound (based on its pKa). Cyclic amp can be found in a number of food items such as green vegetables, java plum, borage, and wakame, which makes cyclic amp a potential biomarker for the consumption of these food products. Cyclic amp can be found primarily in blood, cerebrospinal fluid (CSF), feces, and urine, as well as throughout all human tissues. Cyclic amp exists in all living species, ranging from bacteria to humans. In humans, cyclic amp is involved in several metabolic pathways, some of which include dopamine activation of neurological reward system, excitatory neural signalling through 5-HTR 4 and serotonin, intracellular signalling through PGD2 receptor and prostaglandin D2, and thioguanine action pathway. Cyclic amp is also involved in several metabolic disorders, some of which include adenosine deaminase deficiency, gout or kelley-seegmiller syndrome, purine nucleoside phosphorylase deficiency, and adenine phosphoribosyltransferase deficiency (APRT). Moreover, cyclic amp is found to be associated with chronic renal failure, headache, meningitis, and hypoxic-ischemic encephalopathy. Cyclic adenosine monophosphate (cAMP, cyclic AMP, or 3,5-cyclic adenosine monophosphate) is a second messenger important in many biological processes. cAMP is a derivative of adenosine triphosphate (ATP) and used for intracellular signal transduction in many different organisms, conveying the cAMP-dependent pathway. It should not be confused with 5-AMP-activated protein kinase (AMP-activated protein kinase) . Cyclic AMP (cAMP) or cyclic adenosine monophosphate is an adenine nucleotide containing one phosphate group which is esterified to both the 3- and 5-positions of the sugar moiety. cAMP is found in all organisms ranging from bacteria to plants to animals. In humans and other mammals it is a second messenger and a key intracellular regulator, functioning as a mediator of activity for a number of hormones, including epinephrine, glucagon and ACTH. cAMP is synthesized from ATP by adenylate cyclase. Adenylate cyclase is located at the inner side of cell membranes. Adenylate cyclase is activated by the hormones glucagon and adrenaline and by G protein. Liver adenylate cyclase responds more strongly to glucagon, and muscle adenylate cyclase responds more strongly to adrenaline. cAMP decomposition into AMP is catalyzed by the enzyme phosphodiesterase. cAMP is primarily used for intracellular signal transduction, such as transferring into cells the effects of hormones like glucagon and adrenaline, which cannot pass through the plasma membrane. cAMP is also involved in the activation of protein kinases. In addition, cAMP binds to and regulates the function of ion channels such as the HCN channels. Hyperpolarization-activated cyclic nucleotide‚Äìgated (HCN) channels are integral membrane proteins that serve as nonselective voltage-gated cation channels in the plasma membranes of heart and brain cells. HCN channels are sometimes referred to as pacemaker channels because they help to generate rhythmic activity within groups of heart and brain cells.

Myo-Inositol

1,2,3,4,5,6-Hexahydroxycyclohexane, i-inositol, meso-Inositol

myo-Inositol is an inositol isoform. Inositol is a derivative of cyclohexane with six hydroxyl groups, making it a polyol. It also is known as a sugar alcohol, having exactly the same molecular formula as glucose or other hexoses. Inositol exists in nine possible stereoisomers, of which cis-1,2,3,5-trans-4,6-cyclohexanehexol, or myo-inositol is the most widely occurring form in nature. The other known inositols include scyllo-inositol, muco-inositol, D-chiro-inositol, L-chiro-inositol, neo-inositol, allo-inositol, epi-inositol and cis-inositol. myo-Inositol is found naturally in many foods (particularly in cereals with high bran content) and can be used as a sweetner as it has half the sweetness of sucrose (table sugar). myo-Inositol was once considered a member of the vitamin B complex and given the name: vitamin B8. However, because it is produced by the human body from glucose, it is not an essential nutrient, and therefore cannot be called a vitamin. myo-Inositol is a precursor molecule for a number of secondary messengers including various inositol phosphates. In addition, inositol/myo-inositol is an important component of the lipids known as phosphatidylinositol (PI) phosphatidylinositol phosphate (PIP). myo-Inositol is synthesized from glucose, via glucose-6-phosphate (G-6-P) in two steps. First, G-6-P is isomerised by an inositol-3-phosphate synthase enzyme to myo-inositol 1-phosphate, which is then dephosphorylated by an inositol monophosphatase enzyme to give free myo-inositol. In humans, myo-inositol is primarily synthesized in the kidneys at a rate of a few grams per day. myo-Inositol can be used in the management of preterm babies who have or are at a risk of infant respiratory distress syndrome. It is also used as a treatment for polycystic ovary syndrome (PCOS). It works by increasing insulin sensitivity, which helps to improve ovarian function and reduce hyperandrogenism. Reduced levels of myo-inositol have been found in the spinal fluid of depressed patients and levels are significantly reduced in brain samples of suicide victims.

Tetrahydrocannabinol

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

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).

Members of this group include several potent serotonergic hallucinogens found in several unrelated plants, skins of certain toads, and in mammalian brains. They are possibly involved in the etiology of schizophrenia. They are formed as metabolites of serotonin (5-hydroxytryptamine) or tryptamine by the enzyme indolethylamine N-methyltransferase (INMT). The physiological significance of the N-methylating pathway of indoleamine metabolism, and of the methylated end products, is unknown. Because of the known psychotropic properties of the dimethylated amines, their possible involvement in the chemical pathogenesis of mental disorders has received wide interest.

Uridine 5-triphosphate, also known as utp or uridine triphosphoric acid, is a member of the class of compounds known as pyrimidine ribonucleoside triphosphates. Pyrimidine ribonucleoside triphosphates are pyrimidine ribobucleotides with triphosphate group linked to the ribose moiety. Uridine 5-triphosphate is slightly soluble (in water) and an extremely strong acidic compound (based on its pKa). Uridine 5-triphosphate can be found in a number of food items such as persian lime, nectarine, chinese water chestnut, and soft-necked garlic, which makes uridine 5-triphosphate a potential biomarker for the consumption of these food products. Uridine 5-triphosphate can be found primarily in saliva. Uridine 5-triphosphate exists in all living species, ranging from bacteria to humans. In humans, uridine 5-triphosphate is involved in several metabolic pathways, some of which include josamycin action pathway, clomocycline action pathway, chloramphenicol action pathway, and amikacin action pathway. Uridine 5-triphosphate is also involved in several metabolic disorders, some of which include GLUT-1 deficiency syndrome, glycogenosis, type VI. hers disease, MNGIE (mitochondrial neurogastrointestinal encephalopathy), and galactosemia II (GALK). Uridine-5-triphosphate (UTP) is a pyrimidine nucleoside triphosphate, consisting of the organic base uracil linked to the 1 carbon of the ribose sugar, and esterified with tri-phosphoric acid at the 5 position. Its main role is as substrate for the synthesis of RNA during transcription . Uridine triphosphate, also known as 5-UTP or UTP, belongs to the class of organic compounds known as pyrimidine ribonucleoside triphosphates. These are pyrimidine ribobucleotides with triphosphate group linked to the ribose moiety. More specifically, UTP is a pyrimidine nucleoside triphosphate, consisting of the organic base uracil linked to the 1‚Ä≤ carbon of the ribose sugar, and esterified with tri-phosphoric acid at the 5‚Ä≤ position. Uridine triphosphate exists in all living species, ranging from bacteria to plants to humans. The main role of UTP is as substrate for the synthesis of RNA during transcription. UTP is the precursor for the production of CTP via the enzyme known as CTP Synthetase. UTP can be biosynthesized from UDP by the enzyme known as nucleoside diphosphate kinase by using phosphate group from ATP. UTP also has the role of a source of energy or an activator of substrates in a variety of metabolic reactions. For instance UTP can be used to activate Glucose-1-phosphate, leading to the formation of UDP-glucose and inorganic phosphate. The resulting UDP-glucose can be used in the synthesis of glycogen. UTP is also used in the metabolism of galactose, where the activated form of galactose, called UDP-galactose can be converted to UDP-glucose. UDP-glucuronate, another product of UTP reacting with glucuronic acid, is a sugar used in the creation of polysaccharides and is an intermediate in the biosynthesis of ascorbic acid (except in primates and guinea pigs).

C10H10O6 (226.0477)

Prephenate (CAS: 126-49-8), also known as prephenic acid, belongs to the class of organic compounds known as gamma-keto acids and derivatives. These are organic compounds containing an aldehyde substituted with a keto group on the C4 carbon atom. Prephenic acid is an example of an achiral (optically inactive) molecule which has two pseudoasymmetric atoms (i.e. stereogenic but not chirotopic centers): the C1 and the C4 cyclohexadiene ring atoms. Prephenate exists in all living species, ranging from bacteria to humans. Prephenate has been detected, but not quantified, in several different foods, such as American pokeweeds, breadnut tree seeds, common wheats, swiss chards, and breadfruits. The other stereoisomer, i.e. trans or, better, (1r, 4r), is called epiprephenic acid. It has been shown that of the two possible diastereoisomers, the natural prephenic acid is one that has both substituents at higher priority (according to CIP rules) on the two pseudoasymmetric carbons, i.e. the carboxyl and the hydroxyl groups, in the cis configuration, or (1s, 4s) according to the new IUPAC stereochemistry rules (2013). It is biosynthesized by a [3,3]-sigmatropic Claisen rearrangement of chorismate. Prephenic acid, commonly also known by its anionic form prephenate, is an intermediate in the biosynthesis of the aromatic amino acids phenylalanine and tyrosine, as well as of a large number of secondary metabolites of the shikimate pathway. Prephenic acid, more commonly known by its anionic form prephenate, is an intermediate in the biosynthesis of the aromatic amino acids phenylalanine and tyrosine. [HMDB]. Prephenate is found in many foods, some of which are alaska wild rhubarb, chinese chestnut, kai-lan, and globe artichoke.

Deoxyguanosine triphosphate (dGTP) is a nucleoside triphosphate, and a nucleotide precursor used in cells for DNA synthesis. dGTP is used in the polymerase chain reaction technique, in sequencing, and in cloning. It is also the competitor of inhibition onset by acyclovir in the treatment of HSV virus. Under normal physiologic conditions, deoxyguanosine (dGuo) undergoes phosphorolysis by purine nucleoside phosphorylase (PNP, EC 2.4.2.1, an enzyme involved in the recycling of nucleosides and deoxynucleosides in cellular remodeling). However, when PNP is inhibited, deoxycytidine kinase (dCK, EC 2.7.1.74) shunts unmetabolized dGuo into deoxyguanosine triphosphate (dGTP), which accumulates and blocks DNA synthesis. Deficiency of purine nucleoside phosphorylase results in defective T-cell immunity. A correlation between the degree of T cell inhibition and the level of dCK activity has been observed.

Xanthosine 5-triphosphate (XTP) is a Guanosine triphosphate (GTP) analogue. The base of XTP, xanthine, bears a keto group instead of an amino group at C2 of the purine rings. XTP can substitute for GTP in supporting receptor-mediated adenylyl cyclase activation. XTP competitively inhibits the binding of GTP to the guanine nucleotide-binding site of retinal G-protein, transducin (TD). These suggests that GTP, ITP, and XTP are differential signal sorters and signal amplifiers at the G-protein level. G-proteins mediate signal transfer from receptors to effector systems.

Fluoride

Fluorine anion

F- (18.9984)

Fluorine (Latin: fluere, meaning "to flow"), is the chemical element with the symbol F and atomic number 9. It is a nonmetallic, diatomic gas that is a trace element and member of the halogen family. Pure fluorine (F2) is a corrosive, poisonous, pale yellowish brown gas that is a powerful oxidizing agent. It is the most reactive and electronegative of all the elements (4.0), and readily forms compounds with most other elements. Fluorine even combines with the noble gases, krypton, xenon, and radon. Even in dark, cool conditions, fluorine reacts explosively with hydrogen. It is so reactive that glass, metals, and even water, as well as other substances, burn with a bright flame in a jet of fluorine gas. It is far too reactive to be found in elemental form and has such an affinity for most elements, including silicon, that it can neither be prepared nor be kept in ordinary glass vessels. Instead, it must be kept in specialized quartz tubes lined with a very thin layer of fluorocarbons. In moist air it reacts with water to form also-dangerous hydrofluoric acid. Elemental fluorine is a powerful oxidizer which can cause organic material, combustibles, or other flammable materials to ignite. Both elemental fluorine and fluoride ions are highly toxic and must be handled with great care and any contact with skin and eyes should be strictly avoided. Physiologically, fluorine. exists as an ion in the body. When it is a free element, fluorine has a characteristic pungent odor that is detectable in concentrations as low as 20 nL/L. Fluorine is used in dentistry as flouride (Fluorides) to prevent dental caries. Sodium and stannous salts of fluorine are commonly used in dentifrices. Contact of exposed skin with HF (hydrofluoric acid) solutions posses one of the most extreme and insidious industrial threats-- one which is exacerbated by the fact that HF damages nerves in such a way as to make such burns initially painless. The HF molecule is capable of rapidly migrating through lipid layers of cells which would ordinarily stop an ionized acid, and the burns are typically deep. HF may react with calcium, permanently damaging the bone. More seriously, reaction with the bodys calcium can cause cardiac arrhythmias, followed by cardiac arrest brought on by sudden chemical changes within the body. These cannot always be prevented with local or intravenous injection of calcium salts. HF spills over just 2.5\\% of the bodys surface area, despite copious immediate washing, have been fatal If the patient survives, HF burns typically produce open wounds of an especially slow-healing nature. Fluorine in the form of fluorspar (also called fluorite) (calcium fluoride) was described in 1530 by Georgius Agricola for its use as a flux , which is a substance that is used to promote the fusion of metals or minerals. In 1670 Schwanhard found that glass was etched when it was exposed to fluorspar that was treated with acid. Karl Scheele and many later researchers, including Humphry Davy, Gay-Lussac, Antoine Lavoisier, and Louis Thenard all would experiment with hydrofluoric acid, easily obtained by treating calcium fluoride (fluorspar) with concentrated sulfuric acid. Fluoride is the anion F-, the reduced form of fluorine F. Compounds containing fluoride anions and those containing covalent bonds to fluorine are called fluorides. Fluoride is found in many foods, some of which are rum, black-eyed pea, pear, and corn chip.

Glycerophosphoinositol (CAS: 16824-65-0), also known as 1-(sn-glycero-3-phospho)-1D-myo-inositol, is produced through deacylation by phospholipase B of the essential phospholipid phosphatidylinositol. Glycerophosphoinositols are ubiquitous phosphoinositide metabolites involved in the control of several cell functions. They exert their actions both intracellularly and by rapidly equilibrating across the plasma membrane. Their transport is mediated by the Glut2 transporter, the human ortholog of GIT1 (PMID: 17141226). Glycerophosphoinositol is a substrate for glycerophosphoinositol inositolphosphodiesterase (EC 3.1.4.43) and is involved in the following reaction: 1-(sn-glycero-3-phospho)-1D-myo-inositol + H2O = glycerol + 1D-myo-inositol 1-phosphate. It is also a substrate for glycerophosphoinositol glycerophosphodiesterase (EC 3.1.4.44) which catalyzes the chemical reaction: 1-(sn-glycero-3-phospho)-1D-myo-inositol + H2O = myo-inositol + sn-glycerol 3-phosphate.

Inositol phosphates are compounds containing a phosphate group attached to an inositol (or cyclohexanehexol) moiety. Within humans, inositol 1,3,4-trisphosphate participates in several enzymatic reactions. In particular, inositol 1,3,4-trisphosphate can be converted into 1D-myo-inositol 1,3,4,6-tetrakisphosphate through the action of the enzyme inositol-tetrakisphosphate 1-kinase. In addition, inositol 1,3,4-trisphosphate can be converted into inositol 1,3,4,5-tetraphosphate through its interaction with the enzyme inositol-tetrakisphosphate 1-kinase. In humans, inositol 1,3,4-trisphosphate is involved in inositol metabolism. Inositol 1,3,4-trisphosphate is a specific regulator of cellular signalling.

C6H16O18P4 (499.9287)

myo-Inositol 1,3,4,5-tetrakisphosphate (CAS: 102850-29-3), also known as IP4, is a second messenger responsible for mediating Ca2+ entry through the plasma membrane and mobilizing intracellular Ca2+ by acting synergistically with inositol 1,4,5-trisphosphate (IP3). Inositol 1,4,5-trisphosphate 3-kinase (IP3K, EC 2.7.1.127) phosphorylates IP3 into IP4. Evidence shows that IP4 can activate a protein with ras- and rap-GAP activity and finally inactivate the G protein. This indicates that IP4 regulates Ca2+ influx in a GTP-dependent way, which potentially links the IP3 signalling pathway to GTP-regulated signalling mechanisms. IP4 is demonstrated to be a common regulator in Ca2+ homeostasis. IP4 can bind with a high affinity to several intracellular proteins: synaptotagmin (I and II), Gap1, Btk, and centaurin-alpha and may interact with synaptotagmin to inhibit synaptic transmission. IP4 also acts as a mediator in neuronal death in the ischemic hippocampus. IP4 production is not always associated with a modification in calcium concentration, and control of calcium mobilization is not the sole function proposed for IP4. IP4 defines an essential signalling pathway for T cell precursor responsiveness and development. In the thymus, IP4 is essential during the positive and negative selection of double-positive thymocytes, and in the control of thymocyte reactivity to antigens. IP4 is also a substrate for type I inositol-1,4,5-trisphosphate 5-phosphatase, phosphatidylinositol 4,5-bisphosphate 5-phosphatase A, and skeletal muscle and kidney enriched inositol phosphatase (PMID: 15740635, 14517551).

C20H30O6 (366.2042)

20-Carboxyleukotriene B4 is an omega-oxidized metabolite of leukotriene B4 (LTB4). Neutrophil microsomes are known to oxidize 20-hydroxy-LTB4 (20-OH-LTB4) to its 20-oxo and 20-carboxy derivatives in the presence of NADPH. This activity has been ascribed to LTB4 omega-hydroxylase (cytochrome P-450LTB omega). Leukotriene B4 release from polymorphonuclear granulocytes of severely burned patients was reduced as compared to healthy donor cells. This decrease is due to an enhanced conversion of LTB4 into the 20-hydroxy- and 20-carboxy-metabolites and further to a decreased LTB4-synthesis. LTB4 is the major metabolite in neutrophil polymorphonuclear leukocytes. Leukotrienes are metabolites of arachidonic acid derived from the action of 5-LO (5-lipoxygenase). The immediate product of 5-LO is LTA4 (leukotriene A4), which is enzymatically converted into either LTB4 (leukotriene B4) by LTA4 hydrolase or LTC4 (leukotriene C4) by LTC4 synthase. The regulation of leukotriene production occurs at various levels, including expression of 5-LO, translocation of 5-LO to the perinuclear region and phosphorylation to either enhance or inhibit the activity of 5-LO. Biologically active LTB4 is metabolized by w-oxidation carried out by specific cytochrome P450s (CYP4F) followed by beta-oxidation from the w-carboxy position and after CoA ester formation. Other specific pathways of leukotriene metabolism include the 12-hydroxydehydrogenase/ 15-oxo-prostaglandin-13-reductase that form a series of conjugated diene metabolites that have been observed to be excreted into human urine. Metabolism of LTC4 occurs by sequential peptide cleavage reactions involving a gamma-glutamyl transpeptidase that forms LTD4 (leukotriene D4) and a membrane-bound dipeptidase that converts LTD4 into LTE4 (leukotriene E4) before w-oxidation. These metabolic transformations of the primary leukotrienes are critical for termination of their biological activity, and defects in expression of participating enzymes may be involved in specific genetic disease. (PMID 17623009, 7633595, 2155225, 3039534)Leukotrienes are eicosanoids. The eicosanoids consist of the prostaglandins (PGs), thromboxanes (TXs), leukotrienes (LTs), and lipoxins (LXs). The PGs and TXs are collectively identified as prostanoids. Prostaglandins were originally shown to be synthesized in the prostate gland, thromboxanes from platelets (thrombocytes), and leukotrienes from leukocytes, hence the derivation of their names. All mammalian cells except erythrocytes synthesize eicosanoids. These molecules are extremely potent, able to cause profound physiological effects at very dilute concentrations. All eicosanoids function locally at the site of synthesis, through receptor-mediated G-protein linked signalling pathways.

24,25-Dihydroxyvitamin D (24R,25(OH)2D3) circulates in blood at concentrations about 1000 times higher than 1alpha,25(OH)2D3. 24-Hydroxylase is present in the proximal convoluted tubule cells of the kidney and in virtual all target cells of 1alpha,25(OH)2D3. Interestingly, 1alpha,25(OH)2D3 is a very strong inducer of 24-hydroxylase activity and 24R,25(OH)2D3 formation. Also parathyroid hormone (PTH) regulates 24-hydroxylase activity but in a tissue specific manner, i.e. inhibitory in the kidney while a synergistic effect together with 1alpha,25(OH)2D3 is observed in osteoblasts. Generally, 24-hydroxylation has been considered the first step in the degradation pathway of 1alpha,25(OH)2D3 and 25-(OH)D3. However, through the past decades data have accumulated that 24R,25(OH)2D3 is not merely a degradation product but has effects on its own. Classic studies have demonstrated the significance of 24R,25(OH)2D3 for normal chicken egg hatchability and calcium and phosphorus homeostasis. More recently it became apparent that 24R,25(OH)2D3 also has distinct effects on cartilage in particular the resting zone cells. 24R,25(OH)2D3 stimulates osteocalcin synthesis in human osteoblasts. 24R,25(OH)2D3 plays a role in bone metabolism but that it acts in concert with 1alpha,25(OH)2D3 to obtain an optimal effect.

Tiludronate

{[(4-chlorophenyl)sulfanyl](phosphono)methyl}phosphonic acid

C7H9ClO6P2S (317.9284)

Tiludronate is only found in individuals that have used or taken this drug. It is a bisphosphonate characterized by a (4-chlorophenylthio) group on the carbon atom of the basic P-C-P structure common to all bisphosphonates.The bisphosphonate group binds strongly to the bone mineral, hydroxyapatite. This explains the specific pharmacological action of these compounds on mineralized tissues, especially bone. In vitro studies indicate that tiludronate acts primarily on bone through a mechanism that involves inhibition of osteoclastic activity with a probable reduction in the enzymatic and transport processes that lead to resorption of the mineralized matrix. Bone resorption occurs following recruitment, activation, and polarization of osteoclasts. Tiludronate appears to inhibit osteoclasts by at least two mechanisms: disruption of the cytoskeletal ring structure, possibly by inhibition of protein-tyrosine-phosphatase, thus leading to detachment of osteoclasts from the bone surface and the inhibition of the osteoclastic proton pump.

Adrenoyl ethanolamide is a N-acylethanolamine. N-acylethanolamines (NAEs) constitute a class of lipid compounds naturally present in both animal and plant membranes as constituents of the membrane-bound phospholipid, N-acylphosphatidylethanolamine (NAPE). NAPE is composed of a third fatty acid moiety linked to the amino head group of the commonly occurring membrane phospholipid, phosphatidylethanolamine. NAEs are released from NAPE by phospholipase D-type hydrolases in response to a variety of stimuli. Transient NAE release and accumulation has been attributed a variety of biological activities, including neurotransmission, membrane protection, and immunomodulation in animals. N-oleoylethanolamine is an inhibitor of the sphingolipid signaling pathway, via specific ceramidase inhibition (ceramidase converts ceramide to sphingosine). N-oleoylethanolamine blocks the effects of TNF- and arachidonic acid on intracellular Ca concentration.

Lithium

Lithium, ion (li1+)

Li+ (7.016)

Lithium (Li) is an alkali metal. First described as a mood stabilizer in 1949, it remains an efficacious treatment for bipolar disorders. Recent emerging evidence of its neuroprotective and neurogenic effects alludes to lithiums potential therapeutic use in stroke and neurodegenerative diseases. One intriguing clinical application is in the treatment of Alzheimers disease. Ongoing clinical trials are evaluating lithiums abilities to lower tau and beta-amyloid levels in cerebrospinal fluid in Alzheimers patients. Lithium reduces brain inositol levels by inhibiting the enzyme inositol monophosphatase. This suggests that inositol monophosphatase inhibition is a key mechanism of Lis therapeutic action and that design of new inositol monophosphatase inhibitors may be a practical strategy to create new compounds with Li-like therapeutic effects. Lithium reduces the severity of some behavioral complications of Alzheimers disease (AD). And there are growing indications that Li may be of benefit to the underlying pathology of AD, as well as an array of other common CNS disorders, including stroke, Parkinsons disease, and Huntingtons disease. Physiologically, it exists as an ion in the body. Despite these demonstrated and prospective therapeutic benefits, Lis mechanism of action remains elusive, and opinions differ regarding the most relevant molecular targets. Lithium inhibits several enzymes; significant among these are inositol monophosphatase (IMPase), glycogen synthase kinase-3 (GSK-3), and the proteasome. Lithium has a narrow therapeutic range, and several well characterised adverse effects limit the potential usefulness of higher doses. Acute ingestion in Li-naive patients is generally associated with only short-lived exposure to high concentrations, due to extensive distribution of Li throughout the total body water compartment. Conversely, chronic toxicity and acute-on-therapeutic ingestion are associated with prolonged exposure to higher tissue concentrations and, therefore, greater toxicity. Lithium toxicity may be life threatening, or result in persistent cognitive and neurological impairment. Therefore, enhanced Li clearance has been explored as a means of minimizing exposure to high tissue concentrations. Although haemodialysis is highly effective in removing circulating Li, serum concentrations often rebound so repeated or prolonged treatment may be required. Continuous arteriovenous haemodiafiltration and continuous venovenous haemodiafiltration increase Li clearance, albeit to a lesser extent than haemodialysis, and are more widely accessible. Lithium reduces brain inositol levels by inhibiting IMPase, suggesting that IMPases inhibition is a key mechanism of Lis therapeutic action and that design of new IMPase inhibitors may be a practical strategy to create new compounds with Li-like therapeutic effects. (PMID: 17688381, 17316163, 8110911, 17288494). Lithium is found in many foods, some of which are endive, yellow zucchini, romaine lettuce, and common bean. Lithium (Li) is an alkali metal.

C24H40O5 (408.2876)

3alpha,7alpha,12beta-Trihydroxy-5beta-cholanoic acid, also known as lagocholic acid, is a bile acid. Bile acids with beta-hydroxyl and carbonyl groups at the C-3,7, and/or 12 positions are bile acids usually found in the urine of healthy humans (PMID: 8743575). Bile acids are steroid acids found predominantly in the bile of mammals. The distinction between different bile acids is minute, depending only on the presence or absence of hydroxyl groups on positions 3, 7, and 12. Bile acids are physiological detergents that facilitate excretion, absorption, and transport of fats and sterols in the intestine and liver. Bile acids are also steroidal amphipathic molecules derived from the catabolism of cholesterol. They modulate bile flow and lipid secretion, are essential for the absorption of dietary fats and vitamins, and have been implicated in the regulation of all the key enzymes involved in cholesterol homeostasis. Bile acids recirculate through the liver, bile ducts, small intestine and portal vein to form an enterohepatic circuit. They exist as anions at physiological pH and, consequently, require a carrier for transport across the membranes of the enterohepatic tissues. The unique detergent properties of bile acids are essential for the digestion and intestinal absorption of hydrophobic nutrients. Bile acids have potent toxic properties (e.g. membrane disruption) and there are a plethora of mechanisms to limit their accumulation in blood and tissues (PMID: 11316487, 16037564, 12576301, 11907135).

20-Hydroxy-leukotriene B4

C20H32O5 (352.225)

20-hydroxy- Leukotriene B4 (20-OH-LTB4) is an omega-hydroxylated metabolite of leukotriene B4 in human neutrophils. Elevated urinary concentrations of 20-OH-LTB4 and LTB4 are found in patients with Sjogren-Larsson syndrome (SLS, OMIM 270220), an autosomal recessively inherited neurocutaneous disorder caused by a deficiency of the microsomal enzyme fatty aldehyde dehydrogenase (FALDH), which as an essential role in LTB4 metabolism. Preterm birth seems to be one of the features of the syndrome. The reason for the preterm birth is unclear. It is hypothesized that it relates to the defective LTB4 degradation in SLS. The pathological urinary excretion of LTB4 and 20-OH-LTB4 is a biochemical marker for SLS. Surprisingly, 20-OH-LTB4 concentrations are normal in CSF. Leukotriene B4 is the major metabolite in neutrophil polymorphonuclear leukocytes. Leukotrienes are metabolites of arachidonic acid derived from the action of 5-LO (5-lipoxygenase). The immediate product of 5-LO is LTA4 (leukotriene A4), which is enzymatically converted into either LTB4 (leukotriene B4) by LTA4 hydrolase or LTC4 (leukotriene C4) by LTC4 synthase. The regulation of leukotriene production occurs at various levels, including expression of 5-LO, translocation of 5-LO to the perinuclear region and phosphorylation to either enhance or inhibit the activity of 5-LO. Biologically active LTB4 is metabolized by w-oxidation carried out by specific cytochrome P450s (CYP4F) followed by beta-oxidation from the w-carboxy position and after CoA ester formation. Other specific pathways of leukotriene metabolism include the 12-hydroxydehydrogenase/ 15-oxo-prostaglandin-13-reductase that form a series of conjugated diene metabolites that have been observed to be excreted into human urine. Metabolism of LTC4 occurs by sequential peptide cleavage reactions involving a gamma-glutamyl transpeptidase that forms LTD4 (leukotriene D4) and a membrane-bound dipeptidase that converts LTD4 into LTE4 (leukotriene E4) before w-oxidation. These metabolic transformations of the primary leukotrienes are critical for termination of their biological activity, and defects in expression of participating enzymes may be involved in specific genetic disease. (PMID: 12709426, 9799565, 11408337, 17623009). Leukotrienes are eicosanoids. The eicosanoids consist of the prostaglandins (PGs), thromboxanes (TXs), leukotrienes (LTs), and lipoxins (LXs). The PGs and TXs are collectively identified as prostanoids. Prostaglandins were originally shown to be synthesized in the prostate gland, thromboxanes from platelets (thrombocytes), and leukotrienes from leukocytes, hence the derivation of their names. All mammalian cells except erythrocytes synthesize eicosanoids. These molecules are extremely potent, able to cause profound physiological effects at very dilute concentrations. All eicosanoids function locally at the site of synthesis, through receptor-mediated G-protein linked signalling pathways. 20-hydroxy- Leukotriene B4 (20-OH-LTB4) is an omega-hydroxylated metabolite of leukotriene B4 in human neutrophils. Elevated urinary concentrations of 20-OH-LTB4 and LTB4 are found in patients with Sjogren-Larsson syndrome (SLS, OMIM 270220), an autosomal recessively inherited neurocutaneous disorder caused by a deficiency of the microsomal enzyme fatty aldehyde dehydrogenase (FALDH), which as an essential role in LTB4 metabolism.

scyllo-Inositol

(1R,2R,3R,4R,5R,6R)-Cyclohexane-1,2,3,4,5,6-hexol

scyllo-Inositol or scyllitol is an inositol isoform. Inositol is a derivative of cyclohexane with six hydroxyl groups, making it a polyol. It also is known as a sugar alcohol, having exactly the same molecular formula as glucose or other hexoses. Inositol exists in nine possible stereoisomers, including scyllo-inositol, myo-inositol (the most abundant), muco-inositol, D-chiro-inositol, L-chiro-inositol, neo-inositol, allo-inositol, epi-inositol, and cis-inositol. scyllo-Inositol was first isolated from the kidneys of fish in 1858 by Staedeler and Freierchs. scyllo-Inositol is a naturally occurring plant sugar alcohol found most abundantly in the coconut palm. It appears to accumulate in a number of human tissues and biofluids through dietary consumption. It has traditionally been considered to be a B vitamin although it has an uncertain status as a vitamin and a deficiency syndrome has not been identified in man. (From Martindale, The Extra Pharmacopoeia, 30th ed, p1379). Results reported by Viola et al (PMID: 15340856) suggest that high CSF concentrations of scyllo-inositol can be induced by chronic alcoholism. scyllo-Inositol when fed to transgenic mice that exhibit a memory disease very similar to human Alzheimers disease, can block the accumulation of soluble amyloid-beta (Aβ) plaques in the brain. scyllo-Inositol was found to reverse memory deficits in the mice, reduce the amount of Aβ plaque in the brains of the mice, and reversed other symptoms associated with the presence of Aβ in the brain (PMID: 16767098).

24R,25-Dihydroxyvitamin D3

(3R,6R)-6-[(1R,3aS,4E,7aR)-4-{2-[(1Z,5S)-5-hydroxy-2-methylidenecyclohexylidene]ethylidene}-7a-methyl-octahydro-1H-inden-1-yl]-2-methylheptane-2,3-diol

24R,25-Dihydroxyvitamin D3, also known as 24(R),25(OH)2D3, is a vitamin D metabolite; a dihydroxylated form of the seco-steroid. With the identification of a target cell, the growth plate resting zone (RC) chondrocyte, studies indicate that there are specific membrane-associated signal transduction pathways that mediate both rapid, nongenomic, and genomic responses of RC cells to 24(R),25(OH)2D3. These studies indicate that 24(R),25(OH)2D3 plays an important role in endochondral ossification by regulating less mature chondrocytes and promoting their maturation in the endochondral lineage. 24(R),25(OH)2D3 binds RC chondrocyte membranes with high specificity, increasing protein kinase C (PKC) activity. The effect is stereospecific; 24R,25(OH)2D3, but not 24S,25(OH)2D3, causes the increase, indicating a receptor-mediated response. Phospholipase D-2 (PLD2) activity is increased, resulting in increased production of diacylglycerol (DAG), which in turn activates PKC. 24(R),25(OH)2D3 does not cause translocation of PKC to the plasma membrane but activates existing PKCα. There is a rapid decrease in Ca2+ efflux, and the influx is stimulated. 24(R),25(OH)2D3 also reduces arachidonic acid release by decreasing phospholipase A2 (PLA2) activity, thereby decreasing the available substrate for prostaglandin production via the action of cyclooxygenase-1. PGE2 that is produced acts on the EP1 and EP2 receptors expressed by RC cells to downregulate PKC via protein kinase A, but the reduction in PGE2 decreases this negative feedback mechanism. Both pathways converge on MAP kinase, leading to new gene expression. One consequence of this is the production of new matrix vesicles containing PKCα and PKCγ, and an increase in PKC activity. The chondrocytes also produce 24(R),25(OH)2D3, and the secreted metabolite acts directly on the matrix vesicle membrane. Only PKCγ is directly affected by 24(R),25(OH)2D3 in the matrix vesicles, and activity of this isoform is inhibited. This effect may be involved in the control of matrix maturation and turnover. 24(R),25(OH)2D3 causes RC cells to mature along the endochondral developmental pathway, where they become responsive to 1α,25(OH)2D3 and lose responsiveness to 24(R),25(OH)2D3, a characteristic of more mature growth zone (GC) chondrocytes. 1α,25(OH)2D3 elicits its effects on GC through different signal transduction pathways than those used by 24(R),25(OH)2D3 (PMID: 11179745). 24R,25-Dihydroxyvitamin D3 (24(R),25(OH)2D3 ) is a vitamin D metabolite, a dihydroxylated form of the seco-steroid.

muco-Inositol

(1R,2S,3S,4R,5S,6r)-cyclohexane-1,2,3,4,5,6-hexol

muco-Inositol is an inositol isoform. Inositol is a derivative of cyclohexane with six hydroxyl groups, making it a polyol. It also is known as a sugar alcohol, having exactly the same molecular formula as glucose or other hexoses. Inositol exists in nine possible stereoisomers, including scyllo-inositol, myo-inositol (the most abundant), muco-inositol, D-chiro-inositol, L-chiro-inositol, neo-inositol, allo-inositol, epi-inositol, and cis-inositol. While classed as a sugar-alcohol for historical reasons, muco-inositol is more properly described as a sweet-alcohol due its perception as sweet. However, muco-inositol is perceived as both sweet and salty by humans. It is perceived as salty due to its pair of diaxial-trans-hydroxyl pairs. This pair of hydroxyl groups can form a dimer with the diaxial-trans-hydroxyl pair of the hydrated sodium-ion receptor. muco-Inositol is a critically important chemical in the gustatory (taste) process in mammals. It is coupled to a phospholipid of the outer lemma of the sensory neurons associated with the sodium ion sensitive channel (previously known as the "salty" channel) of gustation. muco-Inositol is typically phosphorylated (becoming muco-inositol phosphate) in the process of being attached to a lipid of the outer lemma of the sensory neurons of taste. The final chemical is phosphatidyl muco-inositol (PtdIns). PtdIns occurs in a specialized area of the cilia of the sensory neurons where it exists in a liquid crystalline form.

Chiro-inositol

(1R,2R,3S,4S,5S,6s)-cyclohexane-1,2,3,4,5,6-hexol

Chiro-inositol, also known as (+)-inositol or (1r,2r,3s,4s,5s,6s)-cyclohexane-1,2,3,4,5,6-hexol, is a member of the class of compounds known as cyclohexanols. Cyclohexanols are compounds containing an alcohol group attached to a cyclohexane ring. Chiro-inositol is soluble (in water) and a very weakly acidic compound (based on its pKa). Chiro-inositol can be found in carob and soy bean, which makes chiro-inositol a potential biomarker for the consumption of these food products. Inositol or its phosphates and associated lipids are found in many foods, in particular fruit, especially cantaloupe and oranges. In plants, the hexaphosphate of inositol, phytic acid or its salts, the phytates, serve as phosphate stores in seed, for example in nuts and beans. Phytic acid also occurs in cereals with high bran content. Phytate is, however, not directly bioavailable to humans in the diet, since it is not digestible. Some food preparation techniques partly break down phytates to change this. However, inositol in the form of glycerophospholipids, as found in certain plant-derived substances such as lecithins is well-absorbed and relatively bioavailable . D-chiro-Inositol (also known as 1D-chiro-inositol, abbreviated DCI) is an inositol isoform. Inositol is a derivative of cyclohexane with six hydroxyl groups, making it a polyol. It also is known as a sugar alcohol, having exactly the same molecular formula as glucose or other hexoses. Inositol exists in nine possible stereoisomers, including scyllo-inositol, myo-inositol (the most abundant), muco-inositol, D-chiro-inositol, L-chiro-inositol, neo-inositol, allo-inositol, epi-inositol, and cis-inositol. myo-Inositol is converted into DCI by an insulin dependent NAD/NADH epimerase enzyme. It is known to be an important secondary messenger in insulin signal transduction. DCI accelerates the dephosphorylation of glycogen synthase and pyruvate dehydrogenase, rate limiting enzymes of non-oxidative and oxidative glucose disposal. DCI may act to bypass defective normal epimerization of myo-inositol to DCI associated with insulin resistance and at least partially restore insulin sensitivity and glucose disposal.

Target: Adrenergic Receptor Prazosin, is a sympatholytic drug used to treat high blood pressure and anxiety, PTSD, andpanic disorder. It is an alpha-adrenergic blocker that is specific for the alpha-1 receptors. These receptors are found on vascular smooth muscle, where they are responsible for the vasoconstrictive action of norepinephrine. They are also found throughout the central nervous system. As of 2013, prazosin is off-patent in the US, and the FDA has approved at least one generic manufacturer.In addition to its alpha-blocking activity, prazosin is an antagonist of the MT3 receptor (which is not present in humans), with selectivity for this receptor over the MT1 and MT2 receptors. Prazosin is orally active and has a minimal effect on cardiac function due to its alpha-1 receptor selectivity. However, when prazosin is initially started, heart rate and contractility go up in order to maintain the pre-treatment blood pressures because the body has reached homeostasis at its abnormally high blood pressure. The blood pressure lowering effect becomes apparent when prazosin is taken for longer periods of time. The heart rate and contractility go back down over time and blood pressure decreases.

C17H23NO3 (289.1678)

Atropine is a racemate composed of equimolar concentrations of (S)- and (R)-atropine. It is obtained from deadly nightshade (Atropa belladonna) and other plants of the family Solanaceae. It has a role as a muscarinic antagonist, an anaesthesia adjuvant, an anti-arrhythmia drug, a mydriatic agent, a parasympatholytic, a bronchodilator agent, a plant metabolite, an antidote to sarin poisoning and a oneirogen. It contains a (S)-atropine and a (R)-atropine. Atropine is an alkaloid originally synthesized from Atropa belladonna. It is a racemic mixture of d-and l-hyoscyamine, of which only l-hyoscyamine is pharmacologically active. Atropine is generally available as a sulfate salt and can be administered by intravenous, subcutaneous, intramuscular, intraosseous, endotracheal and ophthalmic methods. Oral atropine is only available in combination products. Atropine is a competitive, reversible antagonist of muscarinic receptors that blocks the effects of acetylcholine and other choline esters. It has a variety of therapeutic applications, including pupil dilation and the treatment of anticholinergic poisoning and symptomatic bradycardia in the absence of reversible causes. Atropine is a relatively inexpensive drug and is included in the World Health Organization List of Essential Medicines. Atropine is an Anticholinergic and Cholinergic Muscarinic Antagonist. The mechanism of action of atropine is as a Cholinergic Antagonist and Cholinergic Muscarinic Antagonist. Hyoscyamine as a natural plant alkaloid derivative and anticholinergic that is used to treat mild to moderate nausea, motion sickness, hyperactive bladder and allergic rhinitis. Hyoscyamine has not been implicated in causing liver enzyme elevations or clinically apparent acute liver injury. Atropine is a natural product found in Cyphanthera tasmanica, Anthocercis ilicifolia, and other organisms with data available. Atropine Sulfate is the sulfate salt of atropine, a naturally-occurring alkaloid isolated from the plant Atropa belladonna. Atropine functions as a sympathetic, competitive antagonist of muscarinic cholinergic receptors, thereby abolishing the effects of parasympathetic stimulation. This agent may induce tachycardia, inhibit secretions, and relax smooth muscles. (NCI04) Atropine is a synthetically-derived form of the endogenous alkaloid isolated from the plant Atropa belladonna. Atropine functions as a sympathetic, competitive antagonist of muscarinic cholinergic receptors, thereby abolishing the effects of parasympathetic stimulation. This agent may induce tachycardia, inhibit secretions, and relax smooth muscles. (NCI04) Hyoscyamine is a belladonna alkaloid derivative and the levorotatory form of racemic atropine isolated from the plants Hyoscyamus niger or Atropa belladonna, which exhibits anticholinergic activity. Hyoscyamine functions as a non-selective, competitive antagonist of muscarinic receptors, thereby inhibiting the parasympathetic activities of acetylcholine on the salivary, bronchial, and sweat glands, as well as the eye, heart, bladder, and gastrointestinal tract. These inhibitory effects cause a decrease in saliva, bronchial mucus, gastric juices, and sweat. Furthermore, its inhibitory action on smooth muscle prevents bladder contraction and decreases gastrointestinal motility. An alkaloid, originally from Atropa belladonna, but found in other plants, mainly SOLANACEAE. Hyoscyamine is the 3(S)-endo isomer of atropine.

C24H40O5 (408.2876)

Cholic acid, also known as 3a,7a,12a-trihydroxy-5b-cholanate or cholate, belongs to trihydroxy bile acids, alcohols and derivatives class of compounds. Those are prenol lipids structurally characterized by a bile acid or alcohol which bears three hydroxyl groups. Thus, cholic acid is considered to be a bile acid lipid molecule. Cholic acid is practically insoluble (in water) and a weakly acidic compound (based on its pKa). Cholic acid can be found in a number of food items such as cocoa bean, walnut, garden rhubarb, and carob, which makes cholic acid a potential biomarker for the consumption of these food products. Cholic acid can be found primarily in bile, blood, feces, and urine, as well as throughout all human tissues. Cholic acid exists in all living organisms, ranging from bacteria to humans. In humans, cholic acid is involved in few metabolic pathways, which include bile acid biosynthesis, cerebrotendinous xanthomatosis (CTX), congenital bile acid synthesis defect type II, and congenital bile acid synthesis defect type III. Cholic acid is also involved in few metabolic disorders, which include 27-hydroxylase deficiency, familial hypercholanemia (FHCA), and zellweger syndrome. Moreover, cholic acid is found to be associated with biliary atresia, cirrhosis, cystic fibrosis, and primary biliary cirrhosis. Cholic acid is a non-carcinogenic (not listed by IARC) potentially toxic compound.

24 25-Dihydroxy VD3

24,25-Dihydroxyvitamin D3

24,25-Dihydroxyvitamin D (24R,25(OH)2D3) circulates in blood at concentrations about 1000 times higher than 1alpha,25(OH)2D3. 24-Hydroxylase is present in the proximal convoluted tubule cells of the kidney and in virtual all target cells of 1alpha,25(OH)2D3. Interestingly, 1alpha,25(OH)2D3 is a very strong inducer of 24-hydroxylase activity and 24R,25(OH)2D3 formationand is) also parathyroid hormone (PTH) regulates 24-hydroxylase activity but in a tissue specific manner, i.e. inhibitory in the kidney while a synergistic effect together with 1alpha,25(OH)2D3 is observed in osteoblasts. Generally, 24-hydroxylation has been considered the first step in the degradation pathway of 1alpha,25(OH)2D3 and 25-(OH)D3. However, through the past decades data have accumulated that 24R,25(OH)2D3 is not merely a degradation product but has effects on its own. Classic studies have demonstrated the significance of 24R,25(OH)2D3 for normal chicken egg hatchability and calcium and phosphorus homeostasis. More recently it became apparent that 24R,25(OH)2D3 also has distinct effects on cartilage in particular the resting zone cells. 24R,25(OH)2D3 stimulates osteocalcin synthesis in human osteoblasts. 24R,25(OH)2D3 plays a role in bone metabolism but that it acts in concert with 1alpha,25(OH)2D3 to obtain an optimal effect.
