Nucleosides

2'-Deoxy-4-thiouridine is a pyrimidine nucleoside for a range of applications

5'-O-DMT-N2-isobutyryl-2'-O-methylguanosine 3'-CE phosphoramidite is a labile, thermally sensitive chemical compound. It is used as a building block for the synthesis of oligonucleotides.

4-Bromo-3,5-dichloropyridine is a reactive intermediate that is used as a reagent in organic synthesis. It has low basicity and reacts with lithium to form the lithium salt. The salt can be deprotonated to form the bromide anion, which is more reactive than the chloride anion. 4-Bromo-3,5-dichloropyridine can also be used for the selective isomerization of ketones and related compounds. Bromine is added to prevent side reactions with oxygen. The intermediates are generated at the site of reaction by using an excess of diisopropylamide over bromination agent.

2',3'-O-Isopropylidenecytidine is a nucleoside for use in research applications

Ribonucleosides, Deoxyribonucleosides and Activator are a group of synthetic compounds that are used in the synthesis of DNA. Ribonucleosides and Deoxyribonucleosides are nucleotides that contain ribose or deoxyribose as the sugar moiety. Activator is an activator for DNA polymerase, which catalyses the formation of a phosphodiester bond between two adjacent 3'-5' phosphate groups on a single strand of DNA. Ribonuclesides, Deoxyribonucleosides and Activator are used in recombinant DNA technology to synthesize DNA molecules containing modified bases. The CAS number for Ribonuclesides, Deoxyribonucleosides and Activator is 59892-40-9.

2-Hydrazinoadenosine is an active analogue of adenosine. It is a potent agonist for the adenosine receptor subtypes A1 and A2A with high affinity. 2-Hydrazinoadenosine has been shown to inhibit cardiac contractility in animal models, as well as to produce hypotension, bradycardia, and bronchodilation in humans. This drug also has a functional effect on the heart by binding to adenosine receptors, which leads to the inhibition of catecholamine release. This drug is used clinically as an antiarrhythmic agent and a vasodilator in coronary artery disease.

2'-O-Methyluridine is a chemical compound that is used in the synthesis of RNA. It is an analog of uridine and has been shown to have antiviral and anticancer properties. 2'-O-Methyluridine inhibits protein synthesis by competing with uridine for the active site of the enzyme ribonucleotide reductase, which converts ribonucleotides to dNMPs. This compound also inhibits RNA synthesis by disrupting the pairing of adenine and cytosine residues in RNA strands. 2'-O-Methyluridine has been shown to inhibit growth in some types of cancer cells, including colorectal adenocarcinoma cells. It may also be useful as a chemotherapeutic agent against HIV, as it inhibits virus replication by inhibiting reverse transcription and DNA synthesis.

5'-O-DMT-N2-isobutyrylguanosine is a novel phosphoramidite monophosphate, which has been modified with an isobutyryl group. This compound was synthesized in order to be used as a nucleoside analogue and antimetabolite for the treatment of cancer. It also has antiviral properties and inhibits the replication of DNA by inhibiting transcription. 5'-O-DMT-N2-isobutyrylguanosine is an anticancer agent that can be used to treat tumors that are resistant to other chemotherapy drugs. It also inhibits the growth of cells by preventing the synthesis of proteins needed for cell division.

8-Methyladenosine is an acid conjugate that can be found in the urine of healthy people. It is a protonated molecule that binds to a p2 subtype of the G protein-coupled receptor, which is activated by adenosine and 8-methyladenosine. This drug has been used in clinical trials for the treatment of herpes simplex virus and cervical cancer. The intramolecular hydrogen bond between the methyl group and the adenosine ring is responsible for its high binding affinity for this receptor. The glycosidic bond is formed when an 8-methyladenosine molecule attaches to a receptor on a cell surface, forming an intramolecular hydrogen bond with the receptor's amino acid side chain. This bond is broken when a protonated molecule of 8-methyladenosine enters the cell and interacts with the receptor, resulting in activation of this receptor.

2'-Deoxy-L-uridine is a nucleoside that is found in the human body. It phosphorylates l-thymidine, which is a natural substrate, and this reaction prevents the formation of diphosphate from d-ribose 5'-monophosphate. 2'-Deoxy-L-uridine is an exogenous substance that inhibits cell growth by affecting protein synthesis and DNA replication. 2'-Deoxy-L-uridine has been shown to be more efficient than wild type uridine in inhibiting cell growth in vitro at concentrations of 1 mM or greater. The enantiomers of 2'-deoxy-L-uridine affect cell growth differently, with the (R)-enantiomer being more potent than the (S)-enantiomer.

2'-Phosphoadenosine 5'-phosphosulfate tetralithium salt (mixture with 3'-isomer) is a novel, modified nucleoside. It has antiviral properties and can be used for the treatment of cancer. 2'-Phosphoadenosine 5'-phosphosulfate tetralithium salt (mixture with 3'-isomer) inhibits viral replication by inhibiting the synthesis of viral DNA and RNA. This compound also inhibits cancer cell proliferation by inhibiting deoxyribonucleic acid (DNA) and ribonucleic acid (RNA) synthesis.
