Thymidylyl-3'-5'-thymidine ammonium is a cytotoxic drug that belongs to the class of thymidylate synthase inhibitors. It inhibits enzymes responsible for DNA synthesis and repair by binding to the active site of these enzymes and forming covalent bonds with amino acid residues. Thymidylyl-3'-5'-thymidine ammonium can be used as a therapeutic agent in radiation therapy because it is more effective than other drugs at inhibiting cell growth. Thymidylyl-3'-5'-thymidine ammonium has been shown to inhibit the activity of carcinogenic compounds, such as benzo[a]pyrene and benzene, in a model system. Thymidylyl-3'-5'-thymidine ammonium also has the ability to form covalent bonds with dna duplexes and change their conformational properties.

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.

Thymidine is a nucleoside that is found in cells and is involved in the synthesis of DNA. Thymidine has been shown to inhibit the growth of tumor cells through apoptosis. In addition, thymidine can be used for the treatment of bowel disease by reducing inflammation and increasing the production of mucin. The mechanism by which thymidine exerts its effects on tumor cells is not well understood, but it may involve interactions with dna binding activity and enzyme activities.

5'-O-DMT-a-thymidine is a modified nucleoside that is used in the synthesis of DNA and RNA. This product is a high quality and pure monophosphate, which has been modified to reduce its potential for activation by phosphatases. It is suitable for use in anticancer drugs and antiviral agents.

2'-Deoxy-L-cytidine is a nucleoside that is naturally found in the cells of E. coli K-12. It is an antioxidant compound that prevents lipid peroxidation and scavenges free radicals, which are generated by certain chemical reactions. 2'-Deoxy-L-cytidine has been shown to have antiviral potency in vitro, but its antiviral activity has not been evaluated in vivo. This compound also inhibits the growth of bacteria that are resistant to tetracycline, such as Mycobacterium tuberculosis and Helicobacter pylori. 2'-Deoxy-L-cytidine may cause drug interactions with other medications because it is metabolized by the CYP450 system and inhibits the activity of cytochrome P450 enzymes.

2'-Deoxy-5-fluorocytidine is a methyltransferase inhibitor that inhibits the activity of DNA methyltransferases. It has been shown to inhibit the activity of DNA methyltransferases in vitro and in vivo, leading to tumor cell death. 2'-Deoxy-5-fluorocytidine has been shown to target intracellular targets, such as histones and ribosomes, which are involved in cancer development. The toxicity of this drug has been studied extensively and it has been shown to have low toxicity in mice. This drug is not toxic for normal cells or animals when administered at high doses.

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.
