5'-O-Acetyl-2',3'-O-isopropylideneadenosine is an anti-leishmanial agent that is synthesized from 2,3-O-isopropylideneadenosine by acetylating the 5' hydroxyl group. It was found to be more potent than the parent compound and other related compounds in inhibiting Leishmania amazonensis promastigotes. The proposed mechanism of action of 5'-O-acetyl-2',3'-O-isopropylideneadenosine involves hydrogen bonding with the guanosine moiety of DNA and inhibition of RNA synthesis. This drug also has an effect on carbonyl oxygens and resonances, which are observed in the nmr spectra. The synthetic scheme for this drug starts with uridine, which is converted to cytidine by reacting it with sodium cyanide in aqueous solution at 0°C. Cytidine

6-Chloropurine-9-b-D-glucoside is a nucleoside that belongs to the family of modified nucleosides. It is used as an activator and a phosphoramidate in the synthesis of oligonucleotides. 6-Chloropurine-9-b-D-glucoside is also used in anticancer therapy because it inhibits DNA, RNA, and protein synthesis. 6CPG has antiviral activity against herpes virus and other viruses. This compound has been shown to have antiinflammatory activities by inhibiting the production of prostaglandins. 6CPG is also classified as a carcinogen by the International Agency for Research on Cancer (IARC).

2’-Chloro-2’-deoxyadenosine (2CDA) is a synthetic nucleoside analogue that is used as an antineoplastic agent for the treatment of non-Hodgkin lymphoma and histiocytic lymphoma. It is typically used in combination with other cytotoxic drugs. 2CDA has been shown to be effective against resistant tumor cell lines and has been used to treat patients with metastatic breast cancer, Hodgkin lymphoma, and multiple myeloma. The drug can cause thrombocytopenia, which may be due to its effects on platelets or bone marrow cells. Other toxicities include bone marrow suppression, nausea, vomiting, diarrhea, anorexia, and liver damage. Patients who are at risk for these toxicities should be closely monitored.

2’,3’-Dideoxy-5-fluorocytidine is a nucleoside analog that inhibits the growth of tumor cells in animals. It has been shown to inhibit the replication of hepatitis B virus and HIV without affecting normal cell division. 2′,3′-Dideoxy-5-fluorocytidine also has potent antitumor activity against human hematopoietic cells and induces apoptosis.

N,7-Dimethyl-2'-O-methylguanosine (DMOG) is a modified nucleoside with antiviral and anticancer properties. DMOG can be used as an activator of transcription, which activates the synthesis of viral RNA and dsDNA. This compound has shown to inhibit the activity of HIV by preventing reverse transcriptase from synthesizing DNA from viral RNA. It also inhibits tumor cell proliferation by inhibiting DNA synthesis and protein synthesis. DMOG is synthesized in high purity by chemical phosphoramidite chemistry.

5-Fluorocytosine arabinoside (5FCA) is an analog of fluorocytosine and a degradable prodrug that is converted to fluorouracil (5FU) in the human liver. It acts as an inhibitor of DNA synthesis and has been used for the treatment of leukemias. 5-Fluorocytosine arabinoside is rapidly degraded by tissue culture cells, which may be due to its reactive functional groups. The inhibitory activity of this drug against cell culture was found to be minimal at low concentrations and reached a maximum at concentrations greater than 1 mM. The affinity ligands for this compound are reactive functional groups such as sulfhydryl, hydroxyl, and carboxyl groups, but not ester or amide bonds. This drug can be used in the synthesis of affinity ligands with a reactive functional group.

5-Chloro-2',3'-O-isopropylidenecytidine is a synthetic nucleoside that is activated by phosphorylation to form the corresponding nucleotide. It has antiviral and anticancer properties, and can be used as a building block for synthesis of other nucleosides. 5-Chloro-2',3'-O-isopropylidenecytidine is synthesized from 2,4-dichlorophenoxyacetic acid (DCA) and 2,5-dichloroaniline in the presence of sodium cyanide. The compound was first synthesized in 1972 and its chemical structure was determined in 1974. 5-Chloro-2',3'-O-isopropylidenecytidine has been shown to inhibit DNA synthesis by binding to viral diphosphate and deoxyribonucleosides. This compound also inhibits the activity of bacterial DNA gyrase and DNA top

Thymidine 5’-triphosphate (dTTP) sodium hydrate is a fundamental building block in chemical biology. As one of the four natural deoxynucleotides, it plays a crucial role in DNA replication and repair, where dTTP is incorporated into growing DNA strands by DNA polymerases, ensuring fidelity during genetic duplication. The use of dTTP spans various applications, including PCR, DNA sequencing, and site-directed mutagenesis.

Octanoyl CoA is a molecule that belongs to the class of acyl-coenzyme A. It is an important intermediate in fatty acid metabolism and is also used in the synthesis of long-chain fatty acids. Octanoyl CoA can be converted back to acetyl-CoA by enzymes called synthetases, which are active in energy metabolism. Octanoyl CoA has been shown to have clinical relevance for diseases such as acyl chain disorders, carnitine deficiency, and dehydrogenase deficiency. Octanoyl CoA is a potential drug target since it can be converted into octanoic acid, which has been shown to inhibit enzyme activities and protein synthesis.
