Nucléosides

2'-Deoxy-N6-methyladenosine (2DMA) is a nucleoside that has been found to inhibit the phosphorylation of p2y receptors in rat kidney cells. 2DMA inhibits the production of collagen, which may have a matrix effect on cells. Studies have shown that 2DMA can be used as a sample preparation reagent for nuclear DNA. It has also been shown to be effective at inhibiting transcription and replication of human mitochondrial DNA.

An azanucleoside and epigenetic modulator that interferes with nucleic acid metabolism. The compound gets incorporated into RNA and inhibits ribonucleotide reductase subunit RRM2 in leukemia cell lines. Intracellularly, 5-azacytidine can get converted into 2′-deoxy-5-azacytidine (decitabine) and subsequently incorporated in DNA, where it irreversibly inhibits DNMT1 methyltransferase. In human epithelial cell lines, this compound decreases Src-activated expression of a histone chaperone CAF1 and inhibits cell motility and invasiveness.

6-Dimethylamino-9-(b-D-ribofuranosyl)purine (6-DMAP) is an analog of adenine that has been shown to have anticancer activity in human serum and tissue culture. 6-DMAP can inhibit the synthesis of ATP, leading to cell death by significantly inhibiting cellular processes such as glycolysis and DNA replication. 6-DMAP also has a significant cytotoxicity on various types of cancer cells and plant tissues. The mechanism of action for the anticancer activity of 6-DMAP is not yet known, but it may be due to its ability to interfere with purine metabolism or its ability to form covalent bonds with DNA.

guanosine 5'-monophosphate calcium salt is a dietary supplement that contains calcium carbonate and guanosine 5'-monophosphate. This product is a light-exposed supplement that contains phenolic acids, polycarboxylic acids, and cyclic nucleotide phosphodiesterases. It is used to maintain ATP levels in the body. Guanosine 5'-monophosphate calcium salt should not be taken by people with a history of kidney stones or those taking other supplements containing calcium. This product may contain preservatives, excipients, or pharmaceutical ingredients for potency and stability purposes.

Adenosine 5′-phosphosulfate triethylammonium salt serves as a donor of sulfate groups in biochemical processes, such as in the synthesis of sulfate esters. The triethylammonium salt form improves the solubility and stability of the compound, making it useful in laboratory applications involving enzymatic assays and the synthesis of sulfated biomolecules.

2',3',5'-Tri-O-acetyl-2-fluoroadenosine is nucleoside analog of adenosine for use in research. The addition of a fluorine to an adenosine can change adenosine's properties such as its hydrogen bonding ability and how it interacts with water and other biological molecules. It can also increase the stability of adenosine and increase its half-life in biological systems.

9-(b-D-arabinofuranosyl)-8-chloroadenine is a deoxyribonucleoside that is structurally related to adenosine. It has antiviral properties and has been shown to be active against herpes virus, influenza A virus, and cytomegalovirus. 9-(b-D-Arabinofuranosyl)-8-chloroadenine is an activator of cellular DNA polymerase δ and has been shown to inhibit the replication of HIV in human T lymphocytes. 9-(b-D-Arabinofuranosyl)-8-chloroadenine also inhibits the proliferation of tumor cells and is being investigated as a potential chemotherapeutic agent for cancer treatment.

L-Cytidine is a nucleoside that is found in the body, and is also used as a drug. It is a precursor to other nucleosides, such as cytidine triphosphate, which is involved in DNA synthesis and repair. L-Cytidine has been shown to be effective against HIV infection by inhibiting the activity of the enzyme ns3 protease. This inhibition prevents viral proteins from being released from cells and infecting other cells. L-Cytidine has also been shown to be an inhibitor of creatine kinase and glycosidation, two enzymes that are necessary for cell metabolism. L-Cytidine has also been shown to be reactive with halides, which may lead to unwanted side effects.

Coenzyme A trilithium salt is a synthetic cofactor that is used in the synthesis of long-chain fatty acids. It is membrane permeable and has minimal toxicity, making it an attractive candidate for treating hepatic steatosis. Coenzyme A trilithium salt also activates human mitochondrial beta-oxidation by increasing the availability of substrate and enhancing the expression of genes involved in beta-oxidation. This molecule has been shown to be effective in improving the symptoms of X-linked adrenoleukodystrophy (X-ALD) by stimulating creatine kinase activity and suppressing lysosomal accumulation of long chain fatty acids.

1-(5-O-Acetyl-2,3-dideoxy-ß-L-glycero-pent-2-enofuranosyl)-5-fluorouracil is a modified nucleoside analog with structural alterations that enhance its biological properties and stability. The compound features 5-fluorouracil as the nucleobase, a fluorinated pyrimidine often used in chemotherapy due to its ability to interfere with DNA replication. The sugar component is 2,3-dideoxy-β-L-glycero-pent-2-enofuranose and has a specific glycerol and enol configuration, which alters its interactions with enzymes involved in nucleic acid metabolism. The compound includes a 5-O-acetyl protecting group at the 5'-position, which shields the hydroxyl group during synthesis.
