Functions of Nucleoside Derivatives

As research on a range of modified nucleosides has taken off in the fields of chemistry, biology, and pharmacology worldwide, a large number of nucleoside derivatives have been designed and developed. Nucleoside derivatives have structural similarities to natural nucleosides. They can interfere with or directly act on the metabolic process of nucleic acids to interfere with or prevent the production of nucleic acids or proteins. Therefore, nucleoside derivatives are of great significance and practical value in the fields of chemistry, life science, and medicine. It has been found that many nucleoside derivatives show good antibacterial, antiviral, antitumor effects, etc., and show superiority in new anticancer and antiviral aspects. For example, 5-fluorouracil deoxyriboside can play an antitumor role. Its toxicity is not as high as that of 5-fluorouracil, and it is effective against a variety of cancers.

Nucleoside-based Derivative Production Services at CD BioGlyco

CD BioGlyco aims to provide convenient nucleoside derivative production services to clients in various fields. In order to make production more efficient, we are equipped with complete experimental instruments and testing equipment. We have the ability to cope with various difficult productions.

• Nucleoside derivatives production service

We produce nucleoside derivatives by chemical synthesis, enzymatic synthesis, etc. Chemical synthesis is capable of producing a wide range of structurally novel compounds. We produce more types of nucleoside derivatives by chemical synthesis. Enzymatic synthesis has more advantages such as mild reaction conditions, high selectivity, and production of products with a single structure. This method has better application prospects in the production of nucleoside derivatives. We have first-class testing equipment to analyze the structure. We will complete all the experiments from R&D to bioactivity assay according to clients' needs.

• Modification of nucleoside derivatives

The modification of nucleoside derivatives is generally based on the structure of natural nucleosides or active nucleoside analogs. We carry out the corresponding structural modifications in terms of sugar rings, bases, and conformations.

• Base Modification.

Base modifications can be categorized as five-membered cyclic bases, six-membered heterocyclic bases, bicyclic bases, sulfur-containing heterocyclic bases, etc. The modified bases are then linked to the glycosyl group structure to obtain nucleoside analogs. There are more antiviral types of such compounds. Their activity will vary in expression depending on the cell type.

• Glycosyl Group Modification.

Glycosyl group structures have a large number of modification sites. Most of the nucleoside analogs used in clinical applications are glycosyl-modified derivatives. Nucleoside analogs with higher activity can be screened by changing the sugar group structure. It can also further improve the efficacy and pharmacokinetic properties of known drugs and reduce toxic side effects to some extent. Modification of the sugar moiety can be categorized into substitution modification of the sugar ring and modification of the sugar ring structure. According to the substitution at different positions on the sugar ring, our glycosyl group modifications are categorized as 2'-substitution, 3'-substitution, 4'-substitution, 5'-substitution, 2',3'-dideoxy, heteronucleotide, etc. According to the sugar ring structure modification is divided into heterocyclic nucleosides, carbocyclic nucleosides, open ring nucleosides, unsaturated nucleosides, and so on.

• Glycosyl group and base modification at the same time.

In order to enhance the drug activity of nucleoside analogs, improve therapeutic specificity, and reduce the toxicity of the drug, the base and sugar groups are usually modified at the same time.

• Conformational transformation.

Based on the chiral center at the 1'-position, nucleoside analogs are classified into α-conformational and β-conformational nucleosides. Based on mirror symmetry, nucleosides are further classified into D- and L-nucleosides. There are two main types of nucleoside conformational changes, splicing of α- and β-configurations, and conversion of L- and D-configurations.

Applications

• The modification of different types of nucleosides helps in the production of a wide range of structurally different compounds. This also helps in enriching the diversity of nucleoside derivatives.
• Modification of different sites of nucleosides has been used to develop various novel polymerizable drug derivatives.
• Nucleoside derivatives are often used to prepare some complex functionalized self-assemblies. Nucleoside derivatives with different structures are used to study their self-assembly behavior in solution as well as on solid surfaces.

Advantages

• We are familiar with a wide range of reaction types such as condensation, alkylation, etc., and are adept at producing nucleoside derivatives using a variety of chemical methods.
• Nucleoside modifications contribute to the production of compounds with a wide range of activities. We modify nucleosides in terms of sugar rings, bases, and conformations. Nucleoside analogs of different structures can be produced.
• We have a large number of sophisticated testing instruments and various types of specialized analytical equipment to shorten the experimental period and increase the efficiency of production.
