5'-O-Tosylthymidine is a bifunctional reagent that is used in the synthesis of DNA. It is a nucleophilic, inorganic compound that reacts with the electrophilic acrylonitrile group on 5'-hydroxythymidine to form a stable thiophosphate linkage. The reaction takes place stepwise and is catalyzed by an enzyme called DNA polymerase. This product has been used as an antimetabolite in medicine, mainly for treating leukemia.

5-Methyl-L-uridine is an antiviral drug which belongs to a class of compounds called nucleoside analogues. It is used in the treatment of chronic hepatitis B and C, as well as for prevention of hepatitis A and B. 5-Methyl-L-uridine inhibits the virus by turning off the production of viral DNA and RNA, through interactions with the virus's polymerase chain reaction process. This drug also prevents protein synthesis in cells infected with viruses such as HIV, herpes simplex virus type 1, and influenza A virus. 5-Methyl-L-uridine is a prodrug that is converted to its active form, uridine monophosphate, by enzymes in the liver. The cytotoxic effects of 5-methyluridine on cancer cells have been shown to be due to inhibition of cellular DNA synthesis and repair pathways.

2'-Deoxy-4'-ethynyl-2-fluoroadenosine (EFdA) is an analog of adenosine. EFdA is a potent inhibitor of HIV replication, and has been shown to be effective against other viruses such as influenza virus, herpes simplex virus, and vesicular stomatitis virus. EFdA was the first nucleoside analog to show antiviral activity in tissue culture against these viruses. This drug also inhibits the synthesis of mitochondrial rRNA and reduces the formation of mitochondrial DNA in human cells by inhibiting mitochondrial DNA polymerase γ. EFdA also prevents the binding of monoclonal antibodies to human B lymphocytes, which may be due to its steric interactions with plasma RNA. This drug is metabolized by cytochrome P450 2C8 and 2C9 into a variety of metabolites that are excreted in urine as glucuronides or sulfates. EFdA has a long

N2-Benzoylguanosine is a nucleotide derivative that is formed by the acetylation of guanosine. It has been shown to act as a buffer in alkaline solutions and isomerizes to its n-oxide form when heated. N2-Benzoylguanosine reacts with peroxides such as hydrogen peroxide, glyoxal, and organic peroxides, forming hydroperoxide intermediates that can be converted into other products. The acidic hydrolysis of N2-benzoylguanosine yields the corresponding 6-benzoyladenosines. It has been shown to enhance the activity of uridine in inhibiting bacterial growth, while also acting as an inhibitor of viral RNA synthesis. This compound also reacts with nitrous acid to form an n6-benzoyladenosine derivative that inhibits the formation of RNA chains during transcription.

dNaM is a metabolite of DNA that has been shown to be a potential biomarker for metabolic disorders and autoimmune diseases. dNaM levels are elevated in the blood of pregnant women, which may serve as a marker for preeclampsia. Elevated levels have also been observed in patients with type 2 diabetes, obesity, and cancer. Methylation plays an important role in dNaM metabolism. The enzyme DNA methyltransferase (DNMT) catalyzes the transfer of methyl groups from S-adenosyl methionine to cytosine residues on the DNA molecule. DNMT activity is increased by high body mass index (BMI), low vitamin B12 levels, and HIV infection. This enzyme is also inhibited by valproic acid and deprenyl, which may affect dNaM methylation status.

The asymmetric synthesis of archaeosine has been studied in rat liver microsomes, which is a type of cell found in the tissues of the liver. Archaeosine also prevents bacterial enzymes from synthesizing DNA.
