Nucleosides

N6-Benzoyl-2'-deoxy-2'-fluoroadenosine 3'-CE phosphoramidite is a novel nucleoside that has antiviral and anticancer properties. It is an analog of adenosine and inhibits the action of ribonucleotide reductase, which is an enzyme that converts ribonucleotides to deoxyribonucleotides. N6-Benzoyl-2'-deoxy-2'-fluoroadenosine 3'-CE phosphoramidite also inhibits the synthesis of DNA, which may be due to its inhibition of DNA polymerase. This compound has been shown to inhibit the growth of leukemia cells in culture and induce apoptosis in human tumor cells.

2-Thiocytidine is a nucleoside that is an intermediate in the synthesis of thiamine. It has been shown to be effective in the treatment of prostate cancer cells, which may be due to its ability to inhibit protein synthesis. 2-Thiocytidine binds to the catalytic site of ribonucleotide reductase (RR) and inhibits the enzyme's activity, thereby inhibiting DNA synthesis. This drug also has been shown to inhibit crosslinking caused by UV light or other agents that generate reactive oxygen species. 2-Thiocytidine binds to the active site of RR and prevents the formation of the enzyme-substrate complex. This binding prevents reduction of ribose into ribonucleotides and inhibits DNA synthesis.

N4-Acetyl-2'-deoxy-5'-O-DMT-2'-fluorocytidine is a cytosine analog with high affinity for the T cell receptor. It can be used to generate antibodies against cytosine and as a screening tool for plasmon resonance.

N4-Benzoyl-3'-deoxy-5'-O-DMT-cytidine is a synthetic nucleoside that is used as an activator for DNA synthesis. It is also used in the preparation of diphosphate derivatives for use as antiviral and anticancer agents or as probes for DNA and RNA research. N4-Benzoyl-3'-deoxy-5'-O-DMT-cytidine is a novel, high purity, and high quality chemical with CAS No. 86234-45-9.

A P2Y2 receptor agonist that has been studied in cystic fibrosis and retinal diseases such as retinal detachment. Denufosol was studied as an inhaled drug for cystic fibrosis, due to its ability to activate an alternative chloride channel and avoiding the defective CFTR chloride channel. This enhances hydration of the lung mucosa and improves mucociliary clearance.  The drug did not progress from phase III clinical trials. Denufosol resulted in subretinal fluid reabsorption in in vivo model of retinal detachment.

5’(R)-C-Methyl-5-methyluridine is an nucleoside and a ribonucleoside. It has antiviral, anticancer, and DNA modifying properties. This product is used in research to make phosphoramidites, diphosphates, and deoxyribonucleosides. 5’(R)-C-Methyl-5-methyluridine is also used in the production of modified oligonucleotides as well as other novel DNA compounds.

5-Chloro-2'-deoxycytidine (5-Cl-dC) is a nucleoside analog that inhibits DNA synthesis by blocking the action of thymidylate synthase. It can be used in animal models to study bowel diseases, such as ulcerative colitis and Crohn's disease. 5-Cl-dC has been shown to be effective in treating the effects of radiation and chemical toxicity in HL60 cells, a type of human leukemia cell line. 5-Cl-dC has also been shown to enhance the cytotoxicity of eosinophil peroxidase, which is an enzyme that may be involved in the pathogenesis of asthma. This drug is currently being evaluated for its safety and efficacy in clinical trials involving patients with myelodysplastic syndrome or acute myeloid leukemia who are at risk for developing leukemia.

3-(3-Amino-3-carboxypropyl)uridine is an uridine analog that is used in the study of protein synthesis. It can be used to determine the amino acid sequence of a protein, or to identify proteins with similar sequences. 3-(3-Amino-3-carboxypropyl)uridine can also be used to study enzymatic reactions, such as those involved in the synthesis of polypeptides. This molecule has been shown to produce disulfide bonds and form covalent bonds with other molecules. The three-dimensional structure of this molecule has been determined by NMR spectroscopy and X-ray crystallography.

7-Deaza-2'-deoxy-7-iodoadenosine is an oligomer with a stabilized backbone that has been shown to inhibit the growth of bacteria in vitro. It binds to DNA and prevents RNA synthesis. 7-Deaza-2'-deoxy-7-iodoadenosine is a synthetic nucleotide analogue that is used as a probe for mapping RNA sequences and as an inhibitor of bacterial growth. This compound is also used in the synthesis of oligodeoxynucleotides because it has a high affinity for guanine residues, which can be incorporated into the oligonucleotide chain by chemical ligation. The octameric form of 7-deaza-2'-deoxyadenosine is most active against bacterial cells.

4-Hydroxy-6-methylpyrimidine (4-OHMP) is a metabolite of trimethyltin. It is formed in the liver by methylation of 4,6-dimethylpyrimidine (4,6-DMPU). The levels of 4-OHMP in urine samples are used to monitor exposure to this agent. The median values for urinary concentrations of 4-OHMP are typically 10 times higher than those found in blood samples. The metabolite can be detected in urine up to 2 weeks after an individual’s last contact with trimethyltin. This compound has been shown to inhibit the synthesis of glycol dimethyl ethers and carbamates.

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.
