Cytidine
Cytidine is a nucleoside that is composed of the base cytosine linked to the five-carbon sugar D-ribose. Cytidine is a pyrimidine that besides being incorporated into nucleic acids, can serve as a substrate for the salvage pathway of pyrimidine nucleotide synthesis. It is a precursor of cytidine triphosphate (CTP) needed in the phosphatidylcholine (PC) and phosphatidylethanolamine (PE) biosynthetic pathways. These variations probably reflect the species differences in cytidine deaminase, the enzyme that converts cytidine to uridine in the body. The transport of cytidine into the brains extracellular fluid, and then into neurons and glia, are essential prerequisites for cytidine to be utilized in the brain. An efficient mechanism mediating the brain uptake of circulating cytidine has not yet been demonstrated. The biosynthesis of PC, the most abundant phosphatide in the brain, via the Kennedy pathway requires phosphocholine and cytidine triphosphate (CTP), a cytidine nucleotide involved in the rate-limiting step. The enzyme that converts CTP to endogenous CDP-choline (CTP:phosphocholine cytidylyltransferase) is unsaturated at physiological brain CTP levels. APOBEC is a family of enzymes that has been discovered with the ability to deaminate cytidines on RNA or DNA. The human apolipoprotein B mRNA-editing enzyme, catalytic polypeptide-like 3G protein (APOBEC3G, or hA3G), provides cells with an intracellular antiretroviral activity that is associated with the hypermutation of viral DNA through cytidine deamination. Indeed, hA3G belongs to a family of vertebrate proteins that contains one or two copies of a signature sequence motif unique to cytidine deaminases (CTDAs) (PMID: 16769123, 15780864, 16720547).

Cytarabine
Cytarabine, or cytosine arabinoside, a pyrimidine nucleoside analog, is found in mushrooms. Cytarabine is isolated from the mushroom Xerocomus nigromaculatus of unknown palatability. Cytarabine is an antineoplastic anti-metabolite used in the treatment of several forms of leukemia including acute myelogenous leukemia and meningeal leukemia. Cytarabine is an antimetabolite antineoplastic agent that inhibits the synthesis of DNA. Its actions are specific for the S phase of the cell cycle to stop normal cell development and division. Cytarabine is metabolized intracellularly into its active triphosphate form (cytosine arabinoside triphosphate). This metabolite then damages DNA by multiple mechanisms, including the inhibition of alpha-DNA polymerase, inhibition of DNA repair through an effect on beta-DNA polymerase, and incorporation into DNA. The latter mechanism is probably the most important. Cytotoxicity is highly specific for the S phase of the cell cycle. Cytarabine is a chemotherapy agent used mainly in the treatment of hematological malignancies such as acute myeloid leukemia (AML) and non-Hodgkin lymphoma. It is also known as ara C. Cytosine arabinoside is an antimetabolic agent with the chemical name of 1 -arabinofuranosylcytosine. Its mode of action is due to its rapid conversion into cytosine arabinoside triphosphate, which damages DNA when the cell cycle holds in the S phase (synthesis of DNA). Rapidly dividing cells, which require DNA replication for mitosis, are therefore most affected. Cytosine arabinoside also inhibits both DNA and RNA polymerases and nucleotide reductase enzymes needed for DNA synthesis L - Antineoplastic and immunomodulating agents > L01 - Antineoplastic agents > L01B - Antimetabolites > L01BC - Pyrimidine analogues C274 - Antineoplastic Agent > C186664 - Cytotoxic Chemotherapeutic Agent > C272 - Antimetabolite D007155 - Immunologic Factors > D007166 - Immunosuppressive Agents D000890 - Anti-Infective Agents > D000998 - Antiviral Agents D009676 - Noxae > D000963 - Antimetabolites COVID info from COVID-19 Disease Map D000970 - Antineoplastic Agents KEIO_ID C119; [MS2] KO008896 KEIO_ID C119 Corona-virus Coronavirus SARS-CoV-2 COVID-19 SARS-CoV COVID19 SARS2 SARS Cytarabine, a nucleoside analog, causes S phase cell cycle arrest and inhibits DNA polymerase.

Agomelatine
C15H17NO2 (243.12592220000002)
Agomelatine is structurally closely related to melatonin. Agomelatine is a potent agonist at melatonin receptors and an antagonist at serotonin-2C (5-HT2C) receptors, tested in an animal model of depression. Agomelatine was discovered and developed by the European pharmaceutical company Servier Laboratories Ltd. Servier continue to develop the drug and conduct phase III trials in the European Union. In 2005 Servier submitted Agomelatine to the European Medicines Agency (EMEA). On 27 July 2006 the Committee for Medical Products for Human Use (CHMP) of the EMEA recommended a refusal of the marketing authorisation of Valdoxan/Thymanax. The major concern was that efficacy had not been sufficiently shown. In 2006 Servier sold the rights to develop Agomelatine in the US to Novartis. The development for the US market was discontinued in October 2011. It is currently sold in Australia under the Valdoxan trade name.

Prolyl-Glutamine
Prolyl-Glutamine is a dipeptide composed of proline and glutamine. It is an incomplete breakdown product of protein digestion or protein catabolism. Some dipeptides are known to have physiological or cell-signaling effects although most are simply short-lived intermediates on their way to specific amino acid degradation pathways following further proteolysis. This dipeptide has not yet been identified in human tissues or biofluids and so it is classified as an Expected metabolite.
Tiglylcarnitine
Tiglylcarnitine is an acylcarnitine. More specifically, it is an tiglic acid ester of carnitine. Acylcarnitines were first discovered more than 70 year ago (PMID: 13825279). It is believed that there are more than 1000 types of acylcarnitines in the human body. The general role of acylcarnitines is to transport acyl-groups (organic acids and fatty acids) from the cytoplasm into the mitochondria so that they can be broken down to produce energy. This process is known as beta-oxidation. According to a recent review [Dambrova et al. 2021, Physiological Reviews], acylcarnitines (ACs) can be classified into 9 different categories depending on the type and size of their acyl-group: 1) short-chain ACs; 2) medium-chain ACs; 3) long-chain ACs; 4) very long-chain ACs; 5) hydroxy ACs; 6) branched chain ACs; 7) unsaturated ACs; 8) dicarboxylic ACs and 9) miscellaneous ACs. Short-chain ACs have acyl-groups with two to five carbons (C2-C5), medium-chain ACs have acyl-groups with six to thirteen carbons (C6-C13), long-chain ACs have acyl-groups with fourteen to twenty once carbons (C14-C21) and very long-chain ACs have acyl groups with more than 22 carbons. Tiglylcarnitine is therefore classified as a short chain AC. As a short-chain acylcarnitine Tiglylcarnitine is a member of the most abundant group of carnitines in the body, comprising more than 50\\% of all acylcarnitines quantified in tissues and biofluids (PMID: 31920980). Some short-chain carnitines have been studied as supplements or treatments for a number of diseases, including neurological disorders and inborn errors of metabolism. In particular Tiglylcarnitine is elevated in the blood or plasma of individuals with beta ketothiolase deficiency/acat1 gene mutation (PMID: 27264805, PMID: 14518824, PMID: 3435793), and ECHS1 deficiency (PMID: 31908952). It is also decreased in the blood or plasma of individuals with familial mediterranean fever (PMID: 29900937), carcinoma, lewis lung (PMID: 30839735), metabolic syndrome, type 2 diabetes mellitus, and cardiovascular diseases (PMID: 24710945). Tiglylcarnitine is also detected in the urinary organic acid and blood spot acylcarnitine profiles in patients with mitochondrial acetoacetyl-CoA thiolase (T2) deficiency, an inborn error of metabolism affecting isoleucine and ketone bodies in the catabolic process (PMID: 14518824 ). Tiglylcarnitine is found to be associated with celiac disease, which is also an inborn error of metabolism. Tiglylcarnitine has been identified in the human placenta (PMID: 32033212 ). Carnitine acetyltransferase (CrAT, EC:2.3.1.7) is responsible for the synthesis of all short-chain and short branched-chain acylcarnitines (PMID: 23485643). The study of acylcarnitines is an active area of research and it is likely that many novel acylcarnitines will be discovered in the coming years. It is also likely that many novel roles in health and disease will be uncovered. An excellent review of the current state of knowledge for acylcarnitines is available at [Dambrova et al. 2021, Physiological Reviews].

Frovatriptan
Frovatriptan, also known as Frova (trade name), belongs to a class of medications known as 5-hydroxytryptamine agonists (triptan) (PMID: 18001261). It is widely indicated for the treatment of migraine headaches with or without aura in adults (PMID: 22900951, 27103792). It works in the brain to relieve migraine symptoms including headache, pain, nausea, vomiting, sensitivity to light/sound. However, it is not used to treat patients with hemiplegic, ophthalmoplegic or basilar migraine. Frovatriptan binds with high affinity for serotonin 5-HT1B and 5-HT1D receptors, thereby relieving pain by narrowing blood vessels (PMID: 11735616, 12517245). Patient’s may experience some side effects, especially who have heart or blood vessel disease. Frovatriptan is only found in individuals who have consumed or used this drug.

Some short-chain carnitines have been studied as supplements or treatments for a number of diseases, including neurological disorders and inborn errors of metabolism. Carnitine acetyltransferase (CrAT, EC:2.3.1.7) is responsible for the synthesis of all short-chain and short branched-chain acylcarnitines (PMID: 23485643). The study of acylcarnitines is an active area of research and it is likely that many novel acylcarnitines will be discovered in the coming years. It is also likely that many novel roles in health and disease will be uncovered. An excellent review of the current state of knowledge for acylcarnitines is available at [Dambrova et al. 2021, Physiological Reviews].

Arabinofuranosylcytosine
Isolated from the mushroom Xerocomus nigromaculatus of unknown palatability This compound has been identified in human blood as reported by (PMID: 31557052 ). Arabinofuranosylcytosine is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically Arabinofuranosylcytosine is part of the human exposome. The exposome can be defined as the collection of all the exposures of an individual in a lifetime and how those exposures relate to health. An individual's exposure begins before birth and includes insults from environmental and occupational sources. Arabinofuranosylcytosine (Ara-C), also known as cytarabine, is a chemotherapeutic agent that is widely used in the treatment of various types of cancer, particularly hematological malignancies such as acute myeloid leukemia (AML) and chronic myeloid leukemia (CML). The biological functions of Ara-C are primarily related to its antineoplastic properties, which are derived from its mechanism of action within the cell. Here is a detailed description of its biological functions: 1. **Inhibition of DNA Synthesis**: Ara-C functions as a nucleoside analog, which means it resembles the natural building blocks of DNA. Once inside the cell, Ara-C is converted to its active metabolite, araCTP (arabinofuranosylcytosine triphosphate). AraCTP competes with the natural deoxycytidine triphosphate (dCTP) for incorporation into the growing DNA chain during the S phase of the cell cycle. Because Ara-C lacks a 3'-hydroxyl group, its incorporation into DNA leads to chain termination, effectively stopping DNA synthesis. 2. **Cell Cycle Specificity**: Ara-C is most effective against cells that are actively dividing. Since it targets cells in the S phase of the cell cycle, it is particularly harmful to rapidly dividing cancer cells, which often spend a significant portion of their cycle in this phase. 3. **Inhibition of DNA Repair**: Beyond its direct effect on DNA synthesis, Ara-C can also interfere with DNA repair mechanisms. This is because the incorporation of Ara-C into DNA can cause mispairing and induce DNA damage, which the cell may be unable to repair properly. 4. **Cell Death Induction**: The inhibition of DNA synthesis and the induction of DNA damage can lead to cell death through apoptosis or necrosis. Cells that cannot replicate their DNA or repair the damage caused by Ara-C activation are programmed to die, which is a desirable outcome in the context of cancer treatment. 5. **Immune System Modulation**: In some cases, Ara-C can also modulate the immune system, although this is not its primary function. It can affect the function and proliferation of immune cells, which can have implications for both its therapeutic effects and side effects. 6. **Enzymatic Conversion**: Ara-C must be activated within the cell by the enzyme deoxycytidine kinase (dCK), which phosphorylates it to Ara-CMP (monophosphate), then to Ara-CDP (diphosphate), and finally to Ara-CTP. The efficiency of this conversion can vary between different types of cancer cells and normal cells, contributing to the selectivity of Ara-C's action. 7. **Cross-Linking Potential**: Although less common, Ara-C can also form cross-links with DNA, further complicating DNA structure and function, which can contribute to its cytotoxic effects. The biological functions of Ara-C are complex and can vary depending on the dose, the specific cancer type, and the individual patient's metabolism. Its use is carefully monitored in clinical settings due to its potential for significant side effects, including myelosuppression (decreased production of blood cells), gastrointestinal toxicity, and central nervous system toxicity.

3-Methylbut-2-enoylcarnitine
3-methylbut-2-enoylcarnitine is an acylcarnitine. More specifically, it is an 3-methylbut-2-enoic acid ester of carnitine. Acylcarnitines were first discovered more than 70 year ago (PMID: 13825279). It is believed that there are more than 1000 types of acylcarnitines in the human body. The general role of acylcarnitines is to transport acyl-groups (organic acids and fatty acids) from the cytoplasm into the mitochondria so that they can be broken down to produce energy. This process is known as beta-oxidation. According to a recent review [Dambrova et al. 2021, Physiological Reviews], acylcarnitines (ACs) can be classified into 9 different categories depending on the type and size of their acyl-group: 1) short-chain ACs; 2) medium-chain ACs; 3) long-chain ACs; 4) very long-chain ACs; 5) hydroxy ACs; 6) branched chain ACs; 7) unsaturated ACs; 8) dicarboxylic ACs and 9) miscellaneous ACs. Short-chain ACs have acyl-groups with two to five carbons (C2-C5), medium-chain ACs have acyl-groups with six to thirteen carbons (C6-C13), long-chain ACs have acyl-groups with fourteen to twenty once carbons (C14-C21) and very long-chain ACs have acyl groups with more than 22 carbons. 3-methylbut-2-enoylcarnitine is therefore classified as a short chain AC. As a short-chain acylcarnitine 3-methylbut-2-enoylcarnitine is a member of the most abundant group of carnitines in the body, comprising more than 50\\% of all acylcarnitines quantified in tissues and biofluids (PMID: 31920980). Some short-chain carnitines have been studied as supplements or treatments for a number of diseases, including neurological disorders and inborn errors of metabolism. Carnitine acetyltransferase (CrAT, EC:2.3.1.7) is responsible for the synthesis of all short-chain and short branched-chain acylcarnitines (PMID: 23485643). The study of acylcarnitines is an active area of research and it is likely that many novel acylcarnitines will be discovered in the coming years. It is also likely that many novel roles in health and disease will be uncovered. An excellent review of the current state of knowledge for acylcarnitines is available at [Dambrova et al. 2021, Physiological Reviews].
