8-Azidoadenosine 3',5'-cyclic monophosphosphate is used for nucleotide labelling via a click reaction involving the azide moiety and a terminal alkyne conjugated to a label. The reaction generates a stable nucleotide labelled adduct containing a triazole link.

2'-Deoxy-8-oxoguanosine (8-OHdG) is a product of oxidative DNA damage. The presence of 8-OHdG in urine has been used to detect and measure the degree of oxidative DNA damage in humans and animals, which may be linked to cancer and aging. When 8-OHdG is excreted into urine, it can react with other molecules such as protein or inorganic phosphorus, causing more oxidative DNA damage. 2'-Deoxy-8-oxoguanosine has also been shown to cause cell toxicity by damaging the cell's squamous epithelium, leading to cancer.For the 15N5 labelled version please check ND09970.

An isomer of guanosine, used as a synthesis intermediate.

N6-Isopentenyladenosine-5'-monophosphate sodium salt is an adenosine conjugate acid. It is a monomer of polyribonucleotide chain, which is necessary for the formation of ribonucleic acid (RNA) and deoxyribonucleic acid (DNA). N6-Isopentenyladenosine-5'-monophosphate sodium salt is a conjugate base that has the ability to bind to DNA. This binding prevents the formation of a complex with RNA polymerase, thereby inhibiting transcription and replication.

Second messenger in intracellular signal transduction

5-Methylcytidine is a nucleoside that is found in DNA and RNA. It is used in structural biology to probe the structure of DNA. 5-Methylcytidine binds to the enzyme methyl transferase, which catalyzes the transfer of a methyl group from S-adenosylmethionine to produce 5-methyluridine. This reaction occurs in long-term toxicity studies using primary cells, such as lymphocytes and fibroblasts. 5-Methylcytidine has been shown to inhibit tumour growth in mice by binding to nuclear dna polymerase and blocking transcription. The binding site for this drug on the polymerase is located at the same site as that for nucleoside analogues like azidothymidine (AZT) and zidovudine (AZT).

1-(b-D-Arabinofuranosyl)uracil is a nucleoside analog containing uracil, a nitrogenous base found in RNA, and a β-D-Arabinofuranose sugar. This compound could be used to study its effects on DNA/RNA synthesis.

L-Adenosine is a nucleoside that is naturally synthesized in the body and is also found in certain foods. It has a variety of functions, including as an adenosine receptor agonist, a transport agent, and a substrate for metabolic pathways. In addition to its function as an adenosine receptor agonist, L-adenosine can be transported into mammalian cells by facilitated diffusion. The uptake of L-adenosine into cells is dependent on the concentration of extracellular adenosine and its concentration-response curve has been determined experimentally. L-Adenosine also acts as an inhibitor of phosphodiesterase enzyme which increases cAMP levels in cells. This increase in cAMP leads to increased calcium ion influx into the cell, which may lead to activation of protein kinase A (PKA) and protein kinase C (PKC). L-Adenosine has been shown to have cardiac effects at high concentrations. These effects may be

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.
