Nucléosides

5-azidomethyl-2-deoxyuridine (AmdU) is a nucleoside that contains an azide group. The structure of the nucleoside is similar to thymidine, and it is incorporated into nascent DNA by cellular polymerases, similarly to EdU (NE08701). Unlike EdU that needs to be further modified with azides in the presence of copper catalyst, AmdU can also react in the absence of copper catalyst using spAAC Click Chemistry with strained cycloalkynes, such as cyclooctynes. This enables detection of nascent DNA in benign, copper free conditions.

A chemical oligonucleotide synthesis instead of an enzymatic one allows quick access to bespoke oligonucleotides of the desired sequence. Chemically synthesised oligonucleotide sequences are typically constructed in a 3’ to 5’ direction. Gemcitabine 3'-CE phosphoramidite has been used in the synthesis of an oligonucleotide by single replacement of cytidine for gemcitabine for use in gene silencing experiments.

N6-Benzyladenosine 5'-monophosphate sodium salt is a nucleoside that is not identified. It has been shown to be metabolized by adenosine deaminase and may have antitumor activity. N6-Benzyladenosine 5'-monophosphate sodium salt is also a radioactively labeled adenine analog that has been used in the study of metabolic pathways.

9-(β-D-Xylofuranosyl)adenine is a nucleoside analog that inhibits the activity of adenine nucleotide. It has been shown to be effective against a wide range of viruses and bacteria, including HIV, herpes simplex virus, influenza A virus, and Mycobacterium tuberculosis. The chemical structure of 9-(β-D-Xylofuranosyl)adenine resembles that of adenosine and this similarity confers inhibitory properties on it. 9-(β-D-Xylofuranosyl)adenine is an analog of adenosine. The steric interactions between the intramolecular hydrogen bonds in 9-(β-D-Xylofuranosyl)adenine are weaker than those in adenosine, which allows it to bind more easily with the enzyme responsible for the conversion of adenosine to inosinic acid. This inhibition prevents the formation of ATP from AMP, leading

2'-Deoxy-N2-isobutyryl-5'-O-tritylguanosine is a diphosphate nucleoside analog. It is synthesized by the modified phosphoramidite method and can be used for the synthesis of DNA or RNA. 2'-Deoxy-N2-isobutyryl-5'-O-tritylguanosine has been shown to have anticancer, antiviral and antimicrobial properties in vitro. This product is a novel nucleoside analog that has not been previously described in the literature.

2-Acetamido-6-chloro-9-(2',3',5'-tri-O-acetyl-b-D-ribofuranosyl)purine is a modified purine nucleoside, protected with acetyl groups, which protect the sugar during chemical reactions. This compound is based on a purine ring and also contains an acetamido group at position 2, a chlorine atom at position 6 and a β-D-ribofuranosyl sugar.

8-Bromoinosine is a potent chemical probe that can be used to study the molecular mechanism of cGMP-dependent protein kinase (PKG). 8-Bromoinosine reacts with the acceptor site in PKG, which is located at the base of the active site cleft. Electrons from hydrogen bond donor sites on 8-bromoadenosine are transferred to chloride ion and the resulting 8-bromoinosine chloride complex is an effective inhibitor of PKG. It has been shown that stereoselectivity plays a role in this reaction mechanism.

8-Bromocyclic adenosine diphosphate ribose sodium salt (8BCAR) is a cytosolic cyclase inhibitor that inhibits the synthesis of cyclic adenosine monophosphate (cAMP). 8BCAR blocks the activation of protein kinase A, which is an enzyme involved in the phosphorylation of cAMP. 8BCAR has been shown to inhibit cardiac hypertrophy induced by growth factor-β1 and to increase mitochondrial membrane potential, as well as to suppress cardiomyocyte apoptosis. In addition, this drug can be used for the treatment of cancers such as leukemia and lymphoma.

N6-Benzoyl-5'-O-DMT-2'-O-propynyladenosine 3'-CE phosphoramidite is a modified nucleoside, which is an important building block for DNA and RNA synthesis. It is synthesized by the condensation of 6-benzoyladenosine with 2'-O-propynyladenosin. The stability of this compound has been demonstrated by its resistance to hydrolysis and oxidation, while it can also be activated with a variety of activators, including NaBH4 or NaCNBH3. This novel nucleotide has shown anticancer activity in vivo and antiviral activity against HIV.

2'-Deoxy-L-adenosine is an adenosine analogue that has been shown to inhibit the growth of tumor cells in mice. The mechanism of this inhibition is not well understood, but it is thought that 2'-deoxy-L-adenosine inhibits the adenosine A3 receptor and blocks the activation of toll-like receptors. This drug also has been shown to have anti-inflammatory properties, which may be due to its ability to inhibit prostaglandin synthesis. It has been used as a model system for studying cellular responses to DNA damage caused by ultraviolet radiation. 2'-Deoxy-L-adenosine also has been shown to have a cytotoxic effect on human HL60 cells, which is mediated by nuclear DNA fragmentation.
