Nucleótidos

3-Methyl-2-nitropyridine is a high yield byproduct of formamide, which can be activated to form an intermediate for the synthesis of nucleosides. The kinetics and labeling of this intermediate were studied using a transfer experiment. 3-Methyl-2-nitropyridine is acidic, with a pKa value of 3.6, and is reactive towards nucleophiles. It is also catalytic, yielding methyl groups and dioxane as products when heated at temperatures between 180°C and 220°C. In addition, it undergoes nucleophilic substitutions at methoxy groups.

7-Deaza-2',3'-dideoxyguanosine is a nucleoside analogue that is silylated on the 2' and 3' hydroxyl groups. It is also substituted with a deoxygenated 7-deaza-2',3'-dideoxyribose moiety. The substitution of the ribose sugar with deoxygenated 7-deaza-2',3'-dideoxyribose prevents the formation of hydrogen bonds between the sugar and phosphate backbones, which inhibits the enzyme ribonucleotide reductase from catalyzing the conversion of ribonucleotides to deoxynucleotides. This in turn blocks DNA synthesis, leading to cell death.br>
7-Deaza-2',3'-dideoxyguanosine has been shown to be effective against Mycobacterium tuberculosis and Mycobacterium avium complex.

2,2'-Anhydrocytidine HCl is a nucleoside for use as a DNA synthesis inhibitor

N1-Methylguanosine is a methylated nucleotide that is incorporated into the growing DNA chain during protein synthesis. The incorporation of N1-methylguanosine into the growing DNA chain can cause frameshifting, which creates an unusual amino acid sequence. This effect has been shown in model organisms, such as Saccharomyces cerevisiae and Escherichia coli. In these organisms, N1-methylguanosine has been shown to induce cancer when added to the growth medium. It is also found in urine samples from people with bladder cancer and has been used to identify urinary tract cancers. Titration calorimetry studies have shown that N1-methylguanosine binds to a chelate ligand and forms a disulfide bond with cysteine residues on proteins or peptides, which may lead to mitochondrial dysfunction by interfering with hydrogen bonding interactions. Messenger RNA studies show that N1-methylguanosine inhibits translation of mRNA by binding to

Nelarabine is a drug that prevents the growth of cells by inhibiting the bcr-abl kinase, which is an intracellular target. This drug has been shown to be effective against pediatric patients with t-cell acute lymphoblastic leukemia and adults with chronic myeloid leukemia. Nelarabine has minimal toxicity in humans and is not toxic to healthy cells. It has been shown to have anti-inflammatory properties and may be used as a biomarker for autoimmune diseases. Nelarabine also inhibits angiogenesis, which may be due to its effects on nuclear DNA.

2'-O-Propargylcytidine is a novel nucleoside that has been modified from cytidine. It is designed to inhibit the activity of RNA polymerase and to be used in anticancer therapy. The synthesis of 2'-O-propargylcytidine has been achieved by modifying the nucleotide with propargylic chloride, which is then reacted with sodium cyanide. The resulting product is purified by column chromatography and recrystallization.
2'-O-Propargylcytidine is a phosphoramidite that can be used for DNA synthesis or as a monophosphate in RNA synthesis. This high purity product has a CAS number of 206552-85-4 and it can be used as an activator for ribonucleosides, such as adenosine, guanosine, uridine, cytidine, and thymidine.
