Fludarabine phosphate is an antileukemic drug that inhibits DNA polymerase α and β, as well as other enzymes in the nucleotide synthesis pathway. It is used to treat patients with chronic myelogenous leukemia (CML) who have developed resistance to other treatments. Fludarabine phosphate has been shown to induce a cytotoxic effect against tumor cells by binding to ATP-binding cassette transporter proteins on the cell membrane and inhibiting intracellular targets such as DNA, RNA, and protein synthesis. Fludarabine phosphate has also been shown to inhibit the growth of tumor cells through synergistic interactions with other anticancer drugs such as hydroxyurea or busulfan, which may be due to its ability to inhibit enzyme activities such as erythrocyte alkaline phosphatase.

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-3,4,5,6-tetrahydrouridine (2DTHR) is a cytidine deaminase inhibitor that is used in vitro to inhibit the production of tumor necrosis factor (TNF). 2DTHR has been shown to be active against hepatocellular carcinoma cells. It is also reactive with tumor tissue and can be eliminated at a rate similar to that of deoxycytidine kinase. This drug binds to the enzyme target and inhibits its activity by increasing enzyme levels, which causes cell death. 2DTHR inhibits TNF production in tumor tissue by binding to cytidine deaminase and preventing conversion of cytidine into uracil. This drug has been shown to cause tumor inhibition in vitro.

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

2'-O-Methyluridine-5'-monophosphate triethylammonium salt is a modified nucleoside analogue that is an antiviral agent. It inhibits viral replication by acting as an inhibitor of RNA synthesis and DNA polymerase, which are necessary for the virus to replicate. This compound also has anticancer activity and can be used as a chemotherapeutic agent. 2'-O-Methyluridine-5'-monophosphate triethylammonium salt is synthesized from uracil, phosphoramidite, and triethylamine. It has high purity and high quality with a CAS number of 67624-43-5.

Abacavir 5'-phosphate is a nucleoside analog that inhibits the replication of the herpes virus by covalently binding to the viral DNA polymerase and blocking its ability to polymerize dNTPs. Abacavir 5'-phosphate's anti-viral potency has been shown in vivo using a model with herpes simplex virus, and it has been shown to inhibit viral replication in cell culture. The drug also reacts with cellular components such as proteins, lipids, and nucleic acids, which may lead to drug reactions. Abacavir 5'-phosphate is chemically stable, so it can be subjected to analytical methods without degradation. It is an analog of zidovudine (AZT).

2-Chloroadenosine 5'-monophosphate triethylamine salt is a phosphoramidite that has anticancer and antiviral activities. It is synthesized by reacting 2-chloroadenosine with triethylamine. This product has a novel chemical structure and it can be used as an activator for the synthesis of modified DNA, RNA, and other nucleosides. It is also used in the manufacture of deoxyribonucleosides, ribonucleosides, and other nucleotides.
