Nucléosides

N2-DMF-5'-O-DMT-2'-O-methylguanosine is a novel nucleoside analog that has antiviral, anticancer and immunomodulating properties. It is synthesized from 2′,3′-dideoxyadenosine 5′-monophosphate by the condensation of 2,6-dimethylaniline with methylguanosine 5′-monophosphate and 5,6-dimethylaniline. The modification of the guanine base in N2-DMF-5'-O-DMT-2'-O-methylguanosine to an O6 -methyl group results in increased affinity for the ribonucleotide reductase enzyme (RNR) and inhibition of DNA synthesis.

2-Amino-2'-O-methyladenosine is a modified nucleoside based on adenosine with a 2-amino group on the base, and a 2'-O-methyl group on the sugar.

2'-Deoxy-N2-isobutyrylguanosine (2'-DIBG) is an inhibitor of bacterial translocation that has been shown to inhibit the growth of several bacterial species. This drug binds to fatty acids, which are important for maintaining the integrity of the cell membrane and preventing bacterial translocation. 2'-DIBG also inhibits the production of reactive oxygen species by bacteria, which contributes to its antimicrobial activity. Inflammation can be reduced by inhibiting prostaglandin synthesis with 2'-DIBG. The inhibition of prostaglandin synthesis may be due to its ability to form acid conjugates with fatty acids and dicarboxylic acids, which are precursors for prostaglandins. 2'-DIBG also inhibits the synthesis of adenosine triphosphate (ATP) in bacteria, leading to a decrease in bacterial growth rate.

2'-Azido-2'-deoxycytidine is a nucleoside analog derived from cytidine, in which the 2'-hydroxyl group of the ribose is replaced by an azido group (–N₃), while the cytosine base and remaining sugar structure are preserved. This substitution imparts the molecule with bioorthogonal reactivity, enabling its use in chemical biology applications such as nucleic acid labeling via azide-alkyne "click" chemistry. The azido group also sterically and electronically alters sugar conformation and enzymatic recognition, which can affect its incorporation into DNA or RNA by polymerases. Consequently, 2'-azido-2'-deoxycytidine is a useful research tool.

N6-Benzoyl-2'-deoxy-2'-fluoroadenosine is an oligonucleotide that can be used to modulate the expression of survivin. It inhibits the expression of this protein by binding to its mRNA and preventing translation. N6-Benzoyl-2'-deoxy-2'-fluoroadenosine has shown potential for use in cancer treatment due to its ability to inhibit tumor growth and metastasis. It may also be used in the treatment of autoimmune diseases, such as rheumatoid arthritis, where it can inhibit the production of inflammatory cytokines.

acetylated derivative from 3-(3-amino-3-carboxypropyl)uridine

2'-Deoxy-L-guanosine is a nucleoside that is used as an antibiotic. It inhibits protein synthesis, which leads to cell death. This drug has a high level of resistance against bacteria and is effective in the treatment of gram-positive bacteria. 2'-Deoxy-L-guanosine binds to the ribose phosphate backbone of DNA, phosphorylating it and preventing the base pairing of adenosine with thymine. This inhibits the production of DNA and RNA, leading to cell death. 2'-Deoxy-L-guanosine has been shown to be active against Listeria monocytogenes and Mycobacterium tuberculosis. The enantiomer form is more potent than the racemic mixture, but both forms are effective antibiotics.

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.

Second messenger in intracellular signal transduction

Thymidine, also known as deoxythymidine (dT), is a pyrimidine deoxynucleoside that pairs with deoxyadenosine (dA) in a double stranded DNA. It’s used as a biochemical modulator of antimetabolites such as 5-fluorouracil (5-FU), 1-beta-D-arabinofuranosylcytosine (Cytarabine) and methotrexate (MTX) in cancer therapy. It’s also the enantiomer of telbivudine, an antiviral drug used to treat hepatitis B virus (HBV) infection.

8-Allyloxyadenosine is a novel adenine nucleoside analog. It is an activator of ribonucleosides and deoxyribonucleosides, which can be used as a phosphoramidite for the synthesis of oligodeoxynucleotides. The 8-Allyloxyadenosine has been studied for its anticancer and antiviral properties, with promising results in animal studies. In addition, it has been shown to have anti-inflammatory effects in mice.

2'-O-Methylcytidine is a nucleoside with a hydroxyl group on the 2' carbon. The hydroxyl group makes it an effective inhibitor of viral replication, and it has been shown to be active against HIV-1 in cell culture. 2'-O-Methylcytidine is also metabolized by nucleotide salvage pathways, and the metabolic response can be studied using proton nuclear magnetic resonance (NMR) spectroscopy and x-ray diffraction data. It has been found that 2'-O-Methylcytidine inhibits protein synthesis in cancer cells, and this may be due to its ability to bind to the response element on DNA.

3'-Amino-5'-O-p-anisoyl-2',3'-dideoxyuridine is a novel compound that has been synthesized. This compound is a diphosphate, which can be used as an activator for the synthesis of modified nucleosides and antiviral agents. It is also a DNA phosphoramidite, which can be used in the synthesis of oligonucleotides with high purity and high quality.

11mer_5'P oligonucleotide

5'-Amino-2',5'-dideoxy-2'-fluorouridine is an antiviral drug that is synthesized from the natural compound 5'-deoxy-5'-amino-2',5'-dideoxyuridine. The modified deoxyribonucleosides are activated by phosphorylation and can be incorporated into DNA by DNA polymerase, which prevents viral replication. The monophosphate form of this compound is used in cancer chemotherapy to inhibit the synthesis of RNA and proteins necessary for cell division. 5'-Amino-2',5'-dideoxy-2'-fluorouridine has been shown to be a potent anticancer agent, with activity against a variety of human tumor cell lines.

2-Deoxy-5-vinyluridine (5-VUdR) is a chemical compound that has been shown to cause a mutation in the DNA of herpes simplex virus. The compound is then incorporated into the viral DNA and replicated with each new cell division, leading to mutations in the sequence of its genome. This mutation can either be lethal or nonlethal, depending on how it affects the function of the virus. 5-VUdR has also been shown to affect cancer cells by inhibiting their growth and causing them to undergo apoptosis. This chemical compound also has an effect on animals and humans, as it alters body mass index and causes weight loss. It does this by preventing replication of DNA in cells that produce insulin, which leads to low insulin levels and decreased appetite.END>
