Sialic acid is a class of natural carbohydrate compounds widely present in biological systems, and plays a very important biological function in physiological processes such as cell differentiation, maturation, and intercellular interactions. In the pharmaceutical industry, derivatives with sialic acid as precursors are increasingly used in antiviral drugs, drugs for the treatment of neurological diseases, and diagnostic reagents. Currently, there are two approved drugs for the treatment of H1N1 avian influenza in the world, one is Tamiflu and the other is Leganqing (zanamivir). The Leganqing product is a patented product produced by the British Glanso Company, and the main raw material for the production of Leganqing is sialic acid.
