Sugar-based Methylation Modification Service

By introducing methyl groups on sugar molecules, the chemical properties, stability and interaction ability of nucleosides and nucleotides can be adjusted for specific applications. Sugar-based methylation modifications of nucleosides and nucleotides have a range of research and application areas. On the one hand, such modifications can be used to synthesize drug molecules with specific activities and biological stability. By introducing methyl groups to sugar groups, the metabolic pathway, tissue distribution, and modification of drug molecules can be altered to improve their efficacy and bioavailability. On the other hand, it can also be used to construct novel functional materials. For example, in nucleic acid nanotechnology, the self-assembly behavior and stability of nucleic acid molecules can be regulated by methylation modification to achieve the nanoscale structural design and functional applications. In conclusion, nucleoside and nucleotide sugar-based methylation in abiotic synthesis is a promising area of research.

Sugar-based Methylation Modification Service at CD BioGlyco

CD BioGlyco provides clients with efficient Nucleoside & nucleotide Modification Service and Oligonucleotide Modification Service. Our team performs methylation modification of different types of sugar groups by using state-of-the-art technology and instrumentation to ensure an efficient and controlled modification process to meet your research and application needs. The sugar-based methylation services we offer include the following:

• Chemical modification
  Methyl groups are introduced onto the sugar groups of nucleosides using chemical reactions such as addition and substitution reactions of methylation reagents. The sugar group serves as a substrate and typically contains a functional group, such as a hydroxyl group, that accepts a methyl group in the active site. Suitable methylation reagents including methyl iodide, methyl trifluoromethanesulfonate, and the like are utilized to provide the methyl group. A suitable catalyst is then added to promote the methylation reaction under specific conditions.
• Enzyme-catalyzed modification
  We use halogenated reagents (e.g., bromosuccinimides) to introduce halogen atoms directly into the sugar portion of a nucleoside or nucleotide. These halogenated reagents are highly electrophilic and allow efficient halogen substitution reactions.
