nucleoside

Peldesine (BCX 34) is an effective, competitive, reversible, and orally active inhibitor of purine nucleoside phosphorylase. Peldesine inhibits T-cell proliferation with an IC50 of 800 nM. Peldesine can be used in research on cutaneous T-cell lymphoma, psoriasis and HIV infection.

Nicorandil (SG-75)(Ikorel) acts by relaxing the smooth muscle of the blood vessels, especially those of the venous system. It undertakes this through two methods. Firstly, by activating potassium channels, and secondly by donating nitric oxide to activate the enzyme guanylate cyclase. Guanylate cyclase causes activation of cGMP leading to both arterial and venous vasodilatation by de-phosphorylation of the myosin light chain.

Clofarabine (Clofarex)m, a second generation purine nucleoside analog with antineoplastic activity, inhibits the enzymatic activities of ribonucleotide reductase (IC50 = 65 nM) and DNA polymerase.

Inosine (NSC-20262), an endogenous purine nucleoside produced by the catabolism of adenosine, is an agonist of adenosine receptors A1R and A2AR. Inosine has anti-inflammatory, immunomodulatory, antinociceptive and neuroprotective effects.

Adenosine (D-Adenosine) is a natural product, a ribonucleoside consisting of adenine bound to ribose. Adenosine has vasodilatory, antiarrhythmic and analgesic effects.

Mizoribine (NSC-289637) belongs to the family of 1-Ribosyl-imidazolecarboxamides. Mizoribine has been investigated for the treatment of Rheumatoid Arthritis.

Stavudine (BMY-27857), a nucleoside reverse transcriptase inhibitor analog of thymidine, has activity against HIV.

Cytidine (Cytosine-1-β-D-ribofuranoside) is a pyrimidine nucleoside comprised of a cytosine bound to ribose via a beta-N1-glycosidic bond. Cytidine is a precursor for uridine. Both cytidine and uridine are utilized in RNA synthesis.

2'-O-Methylcytidine is a nucleoside derivative and an inhibitor of hepatitis C virus (HCV) non-structural protein 5B (NS5B; IC50= 3.8 μM).1It inhibits HCV replication in a replicon assay (IC50= 21.2 μM). 1.Migliaccio, G., Tomassini, J.E., Carroll, S.S., et al.Characterization of resistance to non-obligate chain-terminating ribonucleoside analogs that inhibit hepatitis C virus replication in vitroJ.

Adenosine 5'-monophosphate disodium salt (Adenosine Phosphate Disodium) is a purine nucleotide involved in ATP metabolism and is used to study the effects of ATP on cells and organisms. Adenosine 5'-monophosphate disodium salt has been shown to have a variety of biochemical and physiological effects. It has been shown to increase cell metabolism, gene expression, and protein synthesis.

Triazavirin, a nucleoside analogue of nucleic acid, is an antiviral agent.

2',5'-Dideoxyadenosine is a potent and non-competitive adenylyl cyclase inhibitor, binding to the P-site with an IC50 of 3 μM.

Famciclovir (BRL 42810) is a Herpes Simplex Virus Nucleoside Analog DNA Polymerase Inhibitor. The mechanism of action of famciclovir is as a DNA Polymerase Inhibitor, and DNA Polymerase Inhibitor.

Rabeprazole sodium (Habeprazole Sodium) is a 4-(3-methoxypropoxy)-3-methylpyridinyl derivative of timoprazole that is used in the therapy of stomach ulcers and Zollinger-Ellison syndrome. The drug inhibits H(+)-K(+)-exchanging ATPase which is found in gastric parietal cells.

Sorivudine (BV-araU) has antiviral activity against several viruses including varicella zoster virus, herpes simplex type 1 virus, and Epstein-Barr virus by interfering with viral DNA synthesis.

Trifluridine/tipiracil hydrochloride mixture (TAS-102) is a novel oral combination drug containing trifluridine (TFT) and tipiracil hydrochloride (TTP) in a 2:1 molar ratio.

2′-Deoxy-2′-fluoroguanosine is a nucleoside analog that potently inhibits influenza virus A and B strains(EC90 <0.35 μM). 2'-Deoxy-2'-fluoroguanosine is an inhibitor of influenza virus replication in the upper respiratory tract, improving fever and nasal inflammation.

Clevudine (Levovir) is a synthetic pyrimidine analogue with activity against hepatitis B virus (HBV). Intracellularly, clevudine is phosphorylated to its active metabolites, clevudine monophosphate and triphosphate. The triphosphate metabolite competes with thymidine for incorporation into viral DNA, thereby causing DNA chain termination and inhibiting the function of HBV DNA polymerase (reverse transcriptase). Clevudine has a long half-life and shows significant reduction of covalently closed circular DNA (cccDNA), therefore the patient is less likely to have a relapse after treatment is discontinued.

3-Methylcytidine as biomarkers of four different types of cancer: lung cancer, gastric cancer, colon cancer, and breast cancer.

6-O-Methyl Guanosine inhibit colony-forming ability in a malignant xeroderma pigmentosum cell line.

N2-Methylguanosine is a modified nucleoside found at several specific sites in various tRNAs.

Deoxycytidine triphosphate trisodium salt (2'-DEOXYCYTIDINE-5'-TRIPHOSPHATE TRISODI) contributes to antibiotic lethality in stationary-phase mycobacteria.

Deoxycytidine triphosphate is a nucleoside triphosphate.It is a raw material in DNA synthesis. Deoxycytidine triphosphate has many applications, such as real-time PCR, cDNA synthesis, and DNA sequencing.

5-Fluoro-2'-deoxycytidine (2'-DEOXY-5-FLUOROCYTIDINE) is an inhibitor of DNA methyltransferase (DNMT) .
