Cas No.118977-25-6 5-Acetamido-4,7,8,9-tetra-O-acetyl-2-S-phenyl-2-thio-β-neuraminic Acid Methyl Ester

Salivary acid is an important molecule for many viruses, such as influenza virus, to recognize host cells. The thiophenyl modification in this compound may endow it with unique biological activity, which can be used in the design and development of antiviral drugs to prevent virus invasion by interfering with the interaction between the virus and host cell surface sialic acid. In addition, sialic acid is an important component at the end of the sugar chain and is widely present in glycoproteins and glycolipids. This derivative can be used to synthesize complex sugar chains and sugar conjugates, which have important functions in cell recognition, signal transduction, and immune regulation. Through this compound, carbohydrate structures with specific biological functions can be constructed for research and application.
