Effects of Saturation Modification

In the cell, saturation modification of nucleosides and nucleotides can regulate life processes such as gene expression, protein synthesis, and cell signaling. Saturation modification is achieved by changing the sugar group of a nucleoside or nucleotide. For example, introducing different chemical alterations to the sugar group by adding groups such as methyl or acetyl groups can affect the stability, structure, and function of the nucleoside or nucleotide. These modifications can play an important role in the transcription and translation process, regulating the level of gene expression and the rate of protein synthesis. In addition, saturation modifications of nucleosides and nucleotides can affect cellular signaling. This type of modification can create differences in cell sensitivity to different signaling molecules, which in turn regulates important physiological processes such as cell proliferation, differentiation, and apoptosis.

Sugar-based Saturation Modification Service at CD BioGlyco

CD BioGlyco has a world-class Glyco™ Synthesis Platform to provide clients with specialized Nucleoside & Nucleotide and Oligonucleotide modification services. Our experienced technicians will customize your project according to your research needs by introducing suitable modification groups to adjust the saturation of sugar groups, thus changing their chemical and functional properties. Our saturation modification strategy is as follows:

• We use oxidizing agents to carry out oxidation reactions on hydrocarbon chains, oxidizing carbon-carbon single or double bonds to carbon-oxygen single or double bonds. This increases the saturation of the molecule, as well as the polarity and chemical reactivity of the molecule.
• We use specific reaction conditions and catalysts to perform a hydrogenation reaction on a double bond to convert the double bond to a single bond, thereby increasing the saturation of the molecule. Modifying the saturation by hydrogenation reaction can reduce its reactivity, stability, and toxicity.
• We increase the hydrocarbon chain length and unsaturation of a molecule by introducing alkyl functional groups through substitution reactions of nucleosides or nucleotides using alkylating reagents. The dealkylation reaction, on the other hand, removes the already present alkyl functional groups and restores them to the original saturated state.
