C10H13N5O5 (283.0917)


Guanosine (G), also known as 2-amino-inosine, 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 sugar moiety. Guanosine consists of a guanine base attached to a ribose (ribofuranose) ring via a beta-N9-glycosidic bond. Guanosine is a white, crystalline powder with no odor and mild saline taste. It is very soluble in acetic acid, and slightly soluble in water, but insoluble in ethanol, diethyl ether, benzene, and chloroform. Guanosine exists in all living species, ranging from bacteria to plants to humans. High levels of guanosine can be found in clovers, coffee plants, and the pollen of pines. It has been detected, but not quantified in, several different foods, such as leeks, garlic, chicory roots, green bell peppers, and black-eyed peas. Guanosine plays an important role in various biochemical processes including the synthesis of nucleic acids such as RNA and intracellular signal transduction (cGMP). The antiviral drug acyclovir, often used in herpes treatment, and the anti-HIV drug abacavir, are both structurally similar to guanosine. Guanosine can be phosphorylated to become guanosine monophosphate (GMP), cyclic guanosine monophosphate (cGMP), guanosine diphosphate (GDP), and guanosine triphosphate (GTP). In humans, guanosine is involved in intracellular signalling through the adenosine receptors A1R and A2AR (PMID: 31847113). Evidence from rodent and cell models has shown a number of important neurotrophic and neuroprotective effects of guanosine. In particular, it is effective in preventing deleterious consequences of seizures, spinal cord injury, pain, mood disorders and aging-related diseases, such as ischemia, Parkinson‚Äôs and Alzheimer‚Äôs diseases (PMID: 27699087). Studies with rodent models of Parkinson‚Äôs disease have shown that guanosine decreases neuronal apoptotic cell death and increases dopaminergic neurons at substantia nigra pars compacta, accompanied by an improvement of motor symptoms in Parkinson‚Äôs disease (i.e. a reduction of bradykinesia). Guanosine promotes neurite arborization, outgrowth, proliferation and differentiation. Systemic administration of guanosine for eight weeks (8 mg/kg) has been shown to stimulate neuroprogenitors proliferation in the subventricular zone (SVZ) in a mouse model of Parkinsonism (PMID: 27699087). The effect of guanosine treatment is accompanied by an increased number of fibroblast growth factor (FGF-2)-positive cells which is an important regulator of neuroprogenitor/stem cell proliferation, survival and differentiation (PMID: 27699087). Guanosine prevents reactive oxygen species (ROS) generation and cell death in hippocampal slices subjected to the oxygen/glucose deprivation (PMID: 31847113). Guanosine is a purine nucleoside in which guanine is attached to ribofuranose via a beta-N(9)-glycosidic bond. It has a role as a fundamental metabolite. It is a purines D-ribonucleoside and a member of guanosines. It is functionally related to a guanine. Guanosine is a nucleoside comprising guanine attached to a ribose (ribofuranose) ring via a β-N9-glycosidic bond. Guanosine can be phosphorylated to become GMP (guanosine monophosphate), cGMP (cyclic guanosine monophosphate), GDP (guanosine diphosphate) and GTP (guanosine triphosphate) which are factors in signal transduction pathways. Guanosine is a metabolite found in or produced by Escherichia coli (strain K12, MG1655). Guanosine is a natural product found in Ulva australis, Allium chinense, and other organisms with data available. Guanosine is a purine nucleoside formed from a beta-N9-glycosidic bond between guanine and a ribose ring and is essential for metabolism.

It is an alkaloid obtained from Rauwolfia serpentina and other species of Rauwolfia. [Wikipedia]Rescinnamine Binds to and inhibits the angiotensin converting enzyme. Rescinnamine competes with angiotensin I for binding at the angiotensin-converting enzyme, blocking the conversion of angiotensin I to angiotensin II. Inhibition of ACE results in decreased plasma angiotensin II. As angiotensin II is a vasoconstrictor and a negative-feedback mediator for renin activity, lower concentrations result in a decrease in blood pressure and stimulation of baroreceptor reflex mechanisms, which leads to decreased vasopressor activity and to decreased aldosterone secretion.

C8H10N2O4 (198.0641)


Mimosine is only found in individuals that have used or taken this drug. It is an antineoplastic alanine-substituted pyridine derivative isolated from Leucena glauca. [PubChem]Mimosine causes inhibition of DNA replication, changes in the progression of the cells in the cell cycle, and apoptosis. Mimosine appears to introduce breaks into DNA. Mimosine is an iron/zinc chelator. Iron depletion induces DNA double-strand breaks in treated cells, and activates a DNA damage response that results in focal phosphorylation of histones. This leads to inhibition of DNA replication and/or DNA elongation. Some studies indicate that mimosine prevents the initiation of DNA replication, whereas other studies indicate that mimosine disrupts elongation of the replication fork by impairing deoxyribonucleotide synthesis by inhibiting the activity of the iron-dependent enzyme ribonucleotide reductase and the transcription of the cytoplasmic serine hydroxymethyltransferase gene (SHMT). Inhibition of serine hydroxymethyltransferase is moderated by a zinc responsive unit located in front of the SHMT gene.

Deoxycytidine

4-Amino-1-[(2R,4S,5R)-4-hydroxy-5-(hydroxymethyl)tetrahydrofuran-2-yl]pyrimidin-2(1H)-one

C9H13N3O4 (227.0906)


Deoxycytidine, also known as dC, belongs to the class of organic compounds known as pyrimidine 2-deoxyribonucleosides. Pyrimidine 2-deoxyribonucleosides are compounds consisting of a pyrimidine linked to a ribose which lacks a hydroxyl group at position 2. Deoxycytidine is also classified as a deoxyribonucleoside, a component of deoxyribonucleic acid (DNA). Deoxycytidine is similar to the ribonucleoside cytidine, but with one hydroxyl group removed from the 2 position. Deoxycytidine exists in all living species, ranging from bacteria to plants to humans. Degradation of DNA through apoptosis or cell death produces deoxycytidine. Within humans, deoxycytidine participates in a number of enzymatic reactions. In particular, deoxycytidine can be biosynthesized from dCMP through the action of the enzyme cytosolic purine 5-nucleotidase. In addition, deoxycytidine can be converted into dCMP; which is mediated by the enzyme uridine-cytidine kinase-like 1. Deoxycytidine can be phosphorylated at the C-5 position by the enzyme deoxycytidine kinase to produce deoxycytidine monophosphate (dCMP), and to a lesser extent, deoxycytidine diphosphate (dCDP), and deoxycytidine triphosphate (dCTP). Deoxycytidine can also be phosphorylated by thymidine kinase 2 (TK2). Deoxycytidine can potentially be used for the treatment of the metabolic disorder known as thymidine kinase 2 deficiency (TK2 deficiency). TK2 deficiency has three disease subtypes: i) infantile-onset myopathy with rapid progression to early death ii) childhood-onset myopathy, which resembles spinal muscular atrophy (SMA) type III, begins between ages 1 and 12 years with progression to loss of ambulation within few years and iii) late-onset myopathy starting at age 12 year or later with moderate to severe myopathy manifesting as either isolated chronic progressive external ophthalmoplegia (CPEO) or a generalized myopathy with CPEO plus facial and limb weakness, gradual progression, and, in some cases, respiratory failure and loss of ability to walk in adulthood (PMID: 28318037). In mouse models of TK2, dC was shown to delay disease onset, prolong life span and restore mtDNA copy number as well as respiratory chain enzyme activities (PMID: 28318037). One of the principal nucleosides of DNA composed of cytosine and deoxyribose. A nucleoside consists of only a pentose sugar linked to a purine or pyrimidine base, without a phosphate group. When N1 is linked to the C1 of deoxyribose, deoxynucleosides and nucleotides are formed from cytosine and deoxyribose; deoxycytidine monophosphate (dCMP), deoxycytidine diphosphate (dCDP), deoxycytidine triphosphate (dCTP). CTP is the source of the cytidine in RNA (ribonucleic acid) and deoxycytidine triphosphate (dCTP) is the source of the deoxycytidine in DNA (deoxyribonucleic acid). [HMDB].

Deoxycytidine monophosphate (dCMP), also known as deoxycytidylic acid or deoxycytidylate in its conjugate acid and conjugate base forms, respectively, is a deoxynucleotide, and one of the four monomers that make up DNA. In a DNA double helix, it will base pair with deoxyguanosine monophosphate. dCMP belongs to the class of organic compounds known as pyrimidine 2-deoxyribonucleoside monophosphates. These are pyrimidine nucleotides with a monophosphate group linked to the ribose moiety lacking a hydroxyl group at position 2. Deficiency of the enzyme deoxycytidine kinase (EC2.7.1.74) is associated with resistance to antiviral and anticancer chemotherapeutic agents, whereas increased enzyme activity is associated with increased activation of these compounds to cytotoxic nucleoside triphosphate derivatives. dCMP exists in all living species, ranging from bacteria to humans. Within humans, dCMP participates in a number of enzymatic reactions. In particular, dCMP can be converted to dCDP by the enzyme UMP-CMP kinase 2. In addition, dCMP can be converted into deoxycytidine, which is catalyzed by the enzyme cytosolic purine 5-nucleotidase. In humans, dCMP is involved in the metabolic disorder called ump synthase deficiency (orotic aciduria). Outside of the human body, dCMP has been detected, but not quantified in several different foods, such as turnips, garlics, agaves, garden onions, and italian sweet red peppers. dCMP is a deoxycytosine nucleotide containing one phosphate group esterified to the deoxyribose moiety in the 2-,3- or 5- positions.

Deoxyadenosine triphosphate

C10H16N5O12P3 (491.0008)


Deoxyadenosine triphosphate (dATP) is a purine nucleoside triphosphate used in cells for DNA synthesis. A nucleoside triphosphate is a molecule type that contains a nucleoside with three phosphates bound to it. dATP contains the sugar deoxyribose, a precursor to DNA synthesis whereby the two existing phosphate groups are cleaved with the remaining deoxyadenosine monophosphate being incorporated into DNA during replication. Due to its enzymatic incorporation into DNA, photoreactive dATP analogs such as N6-[4-azidobenzoyl–(2-aminoethyl)]-2′-deoxyadenosine-5′-triphosphate (AB-dATP) and N6-[4-[3-(trifluoromethyl)-diazirin-3-yl]benzoyl-(2-aminoethyl)]-2′-deoxyadenosine-5′-triphosphate (DB-dATP) have been used for DNA photoaffinity labeling. When present in sufficiently high levels, dATP 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 deoxyadenosine triphosphate are associated with adenosine deaminase (ADA) deficiency, an inborn error of metabolism. ADA deficiency damages the immune system and causes severe combined immunodeficiency (SCID). People with SCID lack virtually all immune protection from bacteria, viruses, and fungi. They are prone to repeated and persistent infections that can be very serious or life-threatening. These infections are often caused by "opportunistic" organisms that ordinarily do not cause illness in people with a normal immune system. The main symptoms of ADA deficiency are pneumonia, chronic diarrhea, and widespread skin rashes. The mechanism by which dATP functions as an immunotoxin is as follows: 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. Animals obtain their energy by oxidation of foods, plants do so by trapping the sunlight using chlorophyll. However, before the energy can be used, it is first transformed into a form which the organism can handle easily. This special carrier of energy is the molecule adenosine triphosphate, or ATP. The ATP molecule is composed of three components. At the centre is a sugar molecule, [[ribose] (the same sugar that forms the basis of DNA). Attached to one side of this is a base (a group consisting of linked rings of carbon and nitrogen atoms); in this case the base is adenine. The other side of the sugar is attached to a string of phosphate groups. These phosphates are the key to the activity of ATP. ATP consists of a base, in this case adenine (red), a ribose (magenta) and a phosphate chain (blue). ATP works by losing the endmost phosphate group when instructed to do so by an enzyme. This reaction releases a lot of energy, which the organism can then use to build proteins, contact muscles, etc. [HMDB]. dATP is found in many foods, some of which are pepper (c. chinense), squashberry, safflower, and brussel sprouts.

5-Thymidylic acid (conjugate base thymidylate), also known as thymidine monophosphate (TMP), deoxythymidine monophosphate (dTMP), or deoxythymidylic acid (conjugate base deoxythymidylate), is a nucleotide that is used as a monomer in DNA. It is an ester of phosphoric acid with the nucleoside thymidine. dTMP consists of a phosphate group, the pentose sugar deoxyribose, and the nucleobase thymine. Unlike the other deoxyribonucleotides, thymidine monophosphate often does not contain the "deoxy" prefix in its name; nevertheless, its symbol often includes a "d" ("dTMP"). 5-Thymidylic acid belongs to the class of organic compounds known as pyrimidine 2-deoxyribonucleoside monophosphates. These are pyrimidine nucleotides with a monophosphate group linked to the ribose moiety lacking a hydroxyl group at position 2. The neutral species of 5-Thymidylic acid (2-deoxythymidine 5-monophosphate). 5-Thymidylic acid exists in all living species, ranging from bacteria to humans. Within humans, 5-thymidylic acid participates in a number of enzymatic reactions. In particular, 5-thymidylic acid and dihydrofolic acid can be biosynthesized from dUMP and 5,10-methylene-THF by the enzyme thymidylate synthase. In addition, 5-thymidylic acid can be converted into dTDP; which is catalyzed by the enzyme thymidylate synthase. In humans, 5-thymidylic acid is involved in pyrimidine metabolism. Outside of the human body, 5-Thymidylic acid has been detected, but not quantified in several different foods, such as common buckwheats, corn salad, garden cress, squashberries, and star fruits. 5-thymidylic acid, also known as thymidylate or thymidine 5-phosphate, is a member of the class of compounds known as pyrimidine 2-deoxyribonucleoside monophosphates. Pyrimidine 2-deoxyribonucleoside monophosphates are pyrimidine nucleotides with a monophosphate group linked to the ribose moiety lacking a hydroxyl group at position 2. 5-thymidylic acid is slightly soluble (in water) and a moderately acidic compound (based on its pKa). 5-thymidylic acid can be found in a number of food items such as burbot, enokitake, scarlet bean, and garland chrysanthemum, which makes 5-thymidylic acid a potential biomarker for the consumption of these food products. 5-thymidylic acid can be found primarily in feces, as well as in human fibroblasts tissue. 5-thymidylic acid exists in all living species, ranging from bacteria to humans. In humans, 5-thymidylic acid is involved in the pyrimidine metabolism. 5-thymidylic acid is also involved in few metabolic disorders, which include beta ureidopropionase deficiency, dihydropyrimidinase deficiency, MNGIE (mitochondrial neurogastrointestinal encephalopathy), and UMP synthase deficiency (orotic aciduria).

Thymidine-5-triphosphate, also known as ttp or deoxythymidine 5-triphosphoric acid, is a member of the class of compounds known as pyrimidine 2-deoxyribonucleoside triphosphates. Pyrimidine 2-deoxyribonucleoside triphosphates are pyrimidine nucleotides with a triphosphate group linked to the ribose moiety lacking a hydroxyl group at position 2. Thymidine-5-triphosphate is slightly soluble (in water) and an extremely strong acidic compound (based on its pKa). Thymidine-5-triphosphate can be found in a number of food items such as kohlrabi, garden tomato (variety), cardoon, and star anise, which makes thymidine-5-triphosphate a potential biomarker for the consumption of these food products. Thymidine-5-triphosphate exists in all living species, ranging from bacteria to humans. In humans, thymidine-5-triphosphate is involved in the pyrimidine metabolism. Thymidine-5-triphosphate is also involved in few metabolic disorders, which include beta ureidopropionase deficiency, dihydropyrimidinase deficiency, MNGIE (mitochondrial neurogastrointestinal encephalopathy), and UMP synthase deficiency (orotic aciduria). Deoxythymidine triphosphate (dTTP) is one of the four nucleoside triphosphates that are used in the in vivo synthesis of DNA. Unlike the other deoxyribonucleoside triphosphates, thymidine triphosphate does not always contain the "deoxy" prefix in its name. The corresponding ribonucleoside triphosphate is called uridine triphosphate. Thymidine 5-triphosphate, also known as TTP or DTHD5ppp, belongs to the class of organic compounds known as pyrimidine 2-deoxyribonucleoside triphosphates. These are pyrimidine nucleotides with a triphosphate group linked to the ribose moiety lacking a hydroxyl group at position 2. Thymidine 5-triphosphate exists in all living species, ranging from bacteria to humans. Outside of the human body, Thymidine 5-triphosphate has been detected, but not quantified in several different foods, such as elliotts blueberries, mamey sapotes, sesames, alliums, and sweet oranges.

Uridine 5-monophosphate (UMP), also known as uridylic acid or uridylate, belongs to the class of organic compounds known as pyrimidine ribonucleoside monophosphates. These are pyrimidine ribobucleotides with monophosphate group linked to the ribose moiety. UMP consists of a phosphate group, a pentose sugar ribose, and the nucleobase uracil; hence, it is a ribonucleotide monophosphate. Uridine 5-monophosphate exists in all living species, ranging from bacteria to plants to humans. UMP is a nucleotide that is primarily used as a monomer in RNA biosynthesis. Uridine monophosphate is formed from Orotidine 5-monophosphate (orotidylic acid) in a decarboxylation reaction catalyzed by the enzyme orotidylate decarboxylase. Within humans, uridine 5-monophosphate participates in a number of enzymatic reactions. In particular, uridine 5-monophosphate can be converted into uridine 5-diphosphate through the action of the enzyme UMP-CMP kinase. In addition, uridine 5-monophosphate can be biosynthesized from uridine 5-diphosphate through its interaction with the enzyme soluble calcium-activated nucleotidase 1. In brain research studies, uridine monophosphate has been used as a convenient delivery compound for uridine. Uridine is present in many foods, mainly in the form of RNA. Non-phosphorylated uridine is not bioavailable beyond first-pass metabolism. In a study, gerbils fed a combination of uridine monophosphate, choline, and docosahexaenoic acid (DHA) were found to have significantly improved performance in running mazes over those not fed the supplements, implying an increase in cognitive function (PMID: 18606862). 5′-UMP.

Gemcitabine is a nucleoside analog used as chemotherapy. It is marketed as Gemzar by Eli Lilly and Company. As with fluorouracil and other analogues of pyrimidines, the drug replaces one of the building blocks of nucleic acids, in this case cytidine, during DNA replication. The process arrests tumor growth, as new nucleosides cannot be attached to the faulty nucleoside, resulting in apoptosis (cellular suicide).

Hydroxyurea is only found in individuals that have used or taken this drug. It is an antineoplastic agent that inhibits DNA synthesis through the inhibition of ribonucleoside diphosphate reductase. [PubChem]Hydroxyurea is converted to a free radical nitroxide (NO) in vivo, and transported by diffusion into cells where it quenches the tyrosyl free radical at the active site of the M2 protein subunit of ribonucleotide reductase, inactivating the enzyme. The entire replicase complex, including ribonucleotide reductase, is inactivated and DNA synthesis is selectively inhibited, producing cell death in S phase and synchronization of the fraction of cells that survive. Repair of DNA damaged by chemicals or irradiation is also inhibited by hydroxyurea, offering potential synergy between hydroxyurea and radiation or alkylating agents. Hydroxyurea also increases the level of fetal hemoglobin, leading to a reduction in the incidence of vasoocclusive crises in sickle cell anemia. Levels of fetal hemoglobin increase in response to activation of soluble guanylyl cyclase (sGC) by hydroxyurea-derived NO.

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.

Cinobufotalin is a natural product found in Bufo and Bufo bufo with data available. Cinobufotalin is a bufadienolide isolated from toad venom and utilized in traditional Chinese medicine (TCM) for its cardiotonic, diuretic and hemostatic effects, with potential cytotoxic and antineoplastic activities. Upon administration and although the exact mechanism of action(s) (MoAs) through which this agent exerts its effects have yet to be fully discovered, cinobufotalin causes DNA fragmentation, decreases mitochondrial membrane potential (MMP), increases intracellular calcium (Ca2+) ion concentrations and reactive oxygen species (ROS) production, upregulates Fas protein and activates cytochrome C, various caspases, Bid and Bax. This causes cell cycle arrest, induces apoptosis and inhibits tumor cell growth and survival. In addition, cinobufotalin inhibits the activity of sphingosine kinase 1 (SphK1) and induces pro-apoptotic ceramide production, which further promotes tumor cell apoptosis. Cinobufotalin also induces mitochondrial protein cyclophilin D (Cyp-D)-dependent opening of the mitochondrial permeability transition pore (mPTP), which may contribute to cinobufotalin-induced non-apoptotic death of certain tumor cells.
