Nucléosides

5-azidomethyl-2-deoxyuridine (AmdU) is a nucleoside that contains an azide group. The structure of the nucleoside is similar to thymidine, and it is incorporated into nascent DNA by cellular polymerases, similarly to EdU (NE08701). Unlike EdU that needs to be further modified with azides in the presence of copper catalyst, AmdU can also react in the absence of copper catalyst using spAAC Click Chemistry with strained cycloalkynes, such as cyclooctynes. This enables detection of nascent DNA in benign, copper free conditions.

Adenine is a nucleobase found in DNA and RNA. It is an essential component of the human body and is used in the production of phosphoramidites, which are chemical compounds that can be converted into phosphodiester bonds. Adenine has been shown to have anticancer properties, and it may function as a novel activator for other anticancer drugs. Adenine is also used as a monophosphate in some cases. The purity of this compound exceeds 99% and the molecular weight ranges from 162 to 166.5 Daltons.

2'-Deoxy-2'-fluoro-L-uridine is a synthetic nucleoside analog of uridine where the sugar is both fluorinated at the 2' position and in the L-configuration, which is the mirror image of naturally occurring D-nucleosides. This modification makes it structurally distinct and biologically significant for certain applications in drug development and biochemical research.

7-Deazaadenosine is a synthetic nucleoside that is used as an antiviral and antitumor agent. It has been shown to inhibit the growth of cancer cells in vitro and in vivo. 7-Deazaadenosine also has antiviral activity, inhibiting viral DNA synthesis by interfering with the enzyme DNA polymerase. 7-Deazaadenosine has been shown to be more potent than other deoxyribonucleosides against various HIV strains, including HIV-1 group M and HIV-1 group O. This drug was originally developed for use as a chemotherapeutic agent but has since been used as a research reagent for studying the mechanism of action of various drugs on DNA.

N6-Benzyladenosine 5'-monophosphate sodium salt is a nucleoside that is not identified. It has been shown to be metabolized by adenosine deaminase and may have antitumor activity. N6-Benzyladenosine 5'-monophosphate sodium salt is also a radioactively labeled adenine analog that has been used in the study of metabolic pathways.

3'-O-Methylguanosine 5'-triphosphate lithium is a nucleotide that has been synthesized and characterized. It is a biochemical regulatory molecule that is involved in the synthesis of DNA, RNA, and proteins. 3'-O-Methylguanosine 5'-triphosphate lithium binds to the guanine nucleotide binding protein G, which acts as an allosteric activator of the enzyme ribonucleotide reductase. The reconstituted enzyme system containing 3'-O-methylguanosine 5'-triphosphate lithium has demonstrated a high level of fidelity in the replication of dna templates.

8-Bromoinosine is a potent chemical probe that can be used to study the molecular mechanism of cGMP-dependent protein kinase (PKG). 8-Bromoinosine reacts with the acceptor site in PKG, which is located at the base of the active site cleft. Electrons from hydrogen bond donor sites on 8-bromoadenosine are transferred to chloride ion and the resulting 8-bromoinosine chloride complex is an effective inhibitor of PKG. It has been shown that stereoselectivity plays a role in this reaction mechanism.

N6-Benzoyl-2'-O-(2-methoxyethyl)adenosine is a novel nucleoside that can be used as an antiviral agent. It is an activator of viral polymerase and inhibits the proliferation of cells infected with HIV. This compound has been synthesized from 2'-deoxyadenosine monophosphate, which is a precursor to RNA and DNA synthesis. N6-Benzoyl-2'-O-(2-methoxyethyl)adenosine has also been shown to inhibit the growth of experimental tumors in mice. The synthesis of this compound is reliable and reproducible, making it a high quality product.

2'-Deoxy-L-adenosine is an adenosine analogue that has been shown to inhibit the growth of tumor cells in mice. The mechanism of this inhibition is not well understood, but it is thought that 2'-deoxy-L-adenosine inhibits the adenosine A3 receptor and blocks the activation of toll-like receptors. This drug also has been shown to have anti-inflammatory properties, which may be due to its ability to inhibit prostaglandin synthesis. It has been used as a model system for studying cellular responses to DNA damage caused by ultraviolet radiation. 2'-Deoxy-L-adenosine also has been shown to have a cytotoxic effect on human HL60 cells, which is mediated by nuclear DNA fragmentation.

7-Deaza-2'-deoxyxanthosine is an oligodeoxynucleotide that is a substrate for the enzyme dUTPase. The allyl group on 7-deaza-2'-deoxyxanthosine is used to attach it to the 3' end of DNA, where it acts as a competitive inhibitor of RNA synthesis. The ethyl group at the end of the molecule is used to attach it to the 5' end of DNA, where it inhibits transcription and replication by binding with RNA polymerase. 7-Deaza-2'-deoxyxanthosine has been shown to be effective in preventing stenosis following coronary bypass surgery, as well as in treating heart disease by reducing levels of xanthosine.

2-Methylthioadenosine is a purine nucleoside which induces necrotic cell death. It is the first of its kind to be shown to have activity against squamous carcinoma cells, and is activated by nucleoside phosphorylase in order to produce its cytotoxic form. 2-Methylthioadenosine also inhibits the transcription-polymerase chain reaction and increases oxidative injury. This drug has been shown to have receptor activity in brain cells, as well as chemotactic activity for gland cells. 2-Methylthioadenosine has been used as a model organism for polymerase chain reactions, and has been shown to inhibit p2y receptors in the human colon cancer cell line HT29.
