Thymidine 3′-monophosphate disodium is a chemotherapeutic agent that has been shown to have antiviral and anticancer properties. It is a nucleoside analogue, which mimics the structure of thymidine and inhibits DNA synthesis by interfering with the DNA replication process. Thymidine 3′-monophosphate disodium is also used as an activator in the synthesis of deoxyribonucleosides and ribonucleosides. This product is synthetic, high quality, and not chemically modified. It has CAS number 68698-19-1 and molecular weight of 242.06 g/mol.

2-Methylthioadenosine is a purine nucleoside which induces necrotic cell death. It is the first of its kind to be shown to have activity against squamous carcinoma cells, and is activated by nucleoside phosphorylase in order to produce its cytotoxic form. 2-Methylthioadenosine also inhibits the transcription-polymerase chain reaction and increases oxidative injury. This drug has been shown to have receptor activity in brain cells, as well as chemotactic activity for gland cells. 2-Methylthioadenosine has been used as a model organism for polymerase chain reactions, and has been shown to inhibit p2y receptors in the human colon cancer cell line HT29.

5'-O-(4,4'-Dimethoxytrityl)adenosine is a phosphoramidite that can be used as an activator for the synthesis of DNA. It is also used in the preparation of modified nucleosides and has anticancer activity. 5'-O-(4,4'-Dimethoxytrityl)adenosine is a modified ribonucleoside with high quality and high purity. This product has been shown to have antiviral activity against HIV-1.

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.

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.

L-Cytidine is a nucleoside that is found in the body, and is also used as a drug. It is a precursor to other nucleosides, such as cytidine triphosphate, which is involved in DNA synthesis and repair. L-Cytidine has been shown to be effective against HIV infection by inhibiting the activity of the enzyme ns3 protease. This inhibition prevents viral proteins from being released from cells and infecting other cells. L-Cytidine has also been shown to be an inhibitor of creatine kinase and glycosidation, two enzymes that are necessary for cell metabolism. L-Cytidine has also been shown to be reactive with halides, which may lead to unwanted side effects.

7-Deaza-2'-deoxyxanthosine is an oligodeoxynucleotide that is a substrate for the enzyme dUTPase. The allyl group on 7-deaza-2'-deoxyxanthosine is used to attach it to the 3' end of DNA, where it acts as a competitive inhibitor of RNA synthesis. The ethyl group at the end of the molecule is used to attach it to the 5' end of DNA, where it inhibits transcription and replication by binding with RNA polymerase. 7-Deaza-2'-deoxyxanthosine has been shown to be effective in preventing stenosis following coronary bypass surgery, as well as in treating heart disease by reducing levels of xanthosine.
