Nucleotídeos

Cyclopentenyl cytosine is a cytotoxic drug that inhibits the synthesis of DNA, RNA, and proteins. It is a nucleoside analogue that inhibits the enzyme activity of ribonucleotide reductase. Cyclopentenyl cytosine has significant cytotoxicity against hl-60 cells, as well as squamous carcinoma and MDA-MB-231 breast cancer cells. It also has significant activity against cyclopentenyl, dextran sulfate, and mitochondrial functions in vivo in human cells. Cyclopentenyl cytosine binds to the response element on the DNA strand, preventing transcription of genes for protein synthesis and cell division.

2'-O-Methyluridine-5'-triphosphate sodium salt is a nucleoside containing a 2'-O-methyl group at the 5' position. It is a novel antiviral and anticancer agent that can inhibit viral replication and induce cell apoptosis. This drug has been shown to be effective against herpes simplex virus type 1 (HSV1) and Epstein-Barr virus (EBV) in vitro, as well as some tumor cells in vivo. 2'-O-Methyluridine-5'-triphosphate sodium salt has also been shown to have high purity and high quality, with less than 0.01% impurities by HPLC, NMR, and elemental analysis analyses.

5-Iodocytidine is a nucleoside analogue that has been shown to possess potent antitumor activity. It is also used as a fluorescent probe for detection of uridine in biological samples. 5-Iodocytidine is structurally similar to uridine, which allows it to be taken up by cells and incorporated into RNA. This analog can also be detected with antibody response, as well as with the use of a fluorescence microscope. 5-Iodocytidine may have the potential to treat infectious diseases and autoimmune diseases because it binds to response elements on DNA and activates gene transcription.

Inosine is a purine nucleoside in which hypoxanthine is attached to ribofuranose via a beta-N(9)-glycosidic bond. Inosine derives from a hypoxanthine and a ribofuranose. Inosine plays a key role as a metabolite in bacteria, fungi, humans, and other animals. There is preliminary evidence that inosine may have neurorestorative, anti-inflammatory, immunomodulatory, and cardioprotective effects.

2'-Deoxy-5-propynyluridine is a nucleoside that is naturally synthesized in the body. It is an intermediate in the synthesis of pyrimidine nucleotides and has been shown to be useful for the treatment of cardiac arrhythmias. 2'-Deoxy-5-propynyluridine has also been found to have a stabilizing effect on RNA, enhancing its biological relevance. This compound can be used as a fluorescent probe and can be used to study transcriptional regulation mechanisms.

2'-Deoxy-N6-methyladenosine (2DMA) is a nucleoside that has been found to inhibit the phosphorylation of p2y receptors in rat kidney cells. 2DMA inhibits the production of collagen, which may have a matrix effect on cells. Studies have shown that 2DMA can be used as a sample preparation reagent for nuclear DNA. It has also been shown to be effective at inhibiting transcription and replication of human mitochondrial DNA.
