Nucleótidos

3'-O-Allylguanosine is a antiviral agent that belongs to the group of synthetic nucleosides. It is a monophosphate analog of guanosine and an activator of ribonucleotide reductase. 3'-O-Allylguanosine has been shown to be effective against cancer cells in vitro. It has also been shown to inhibit DNA synthesis and promote DNA degradation in human leukemia cells, suggesting its potential use for the treatment of leukemia.

5-Bromo-2'-deoxyuridine (5-BrDU) is a nitrate reductase inhibitor that prevents the reduction of nitrate to nitrite by inhibiting the enzyme nitrate reductase. It is a genotoxic agent that has been shown to cause DNA damage and cell death in vitro. 5-BrDU has been shown to induce preconditioning in vivo, reducing neuronal injury after ischemia. This drug also binds to NMDA receptors and may be useful as a model system for studying neurodegenerative diseases such as Alzheimer's disease. 5-BrDU has been shown to inhibit the polymerase chain reaction in wild-type strains of bacteria, but not in strains with a mutation in their DNA gyrase genes.

5-Aminouridine is an analog of uridine that is used in the synthesis of RNA. It inhibits the synthesis of RNA by viruses, and it may also inhibit the synthesis of RNA by cells, including muscle cells. 5-Aminouridine has been shown to inhibit protein synthesis in muscle cells incubated with orotic acid. The drug may also interact with other drugs metabolized by UDP-glucose pyrophosphorylase, such as carbamazepine and phenytoin. This interaction may lead to decreased serum levels of these drugs following treatment with 5-aminouridine.

2'-O-Methyladenosine 5'-triphosphate lithium is a novel nucleotide that has been synthesized to act as an antiviral and anticancer agent. It can be used in the production of ribonucleosides, deoxyribonucleosides, and modified DNA. It is also a high quality phosphoramidite that can be used in the synthesis of DNA and RNA. 2'-O-Methyladenosine 5'-triphosphate lithium has been shown to inhibit the replication of HIV-1 and other viruses by inhibiting viral transcription. It is also active against cancer cells, with an IC50 value of 0.2 μM for HL-60 cells.

Inhibitor of uridine monophosphate synthase

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.

2'-C-Methyladenosine 5'-triphosphate triethyl ammonium salt is a synthetic nucleotide analog of adenosine triphosphate (ATP), modified at the 2'-carbon of the ribose ring. This molecule has potential applications in biochemical, enzymatic, and antiviral research, particularly in studies involving RNA synthesis and viral RNA polymerases.
