Research Interests and Highlights

1) Synthesize and study the biological activities of oligosaccharides; 2) Develop new methods for glycosylation coupling; 3) Design and development for tumor immunotherapy drugs. 

Over the past five years, our team has focused on the areas of oligosaccharide synthesis and their biological functions. Based on efficient enzymatic-degradation techniques, we established a semi-synthesis strategy toward defined glycosaminoglycans oligosaccharides, for example, hyaluronic acid, chondroitin sulfate and fucosylated chondroitin sulfate. We applied these structurally defined molecules as tools to investigate the structure activity relationships between GAG and key bio-functions such as coagulant and neurogenesis. We are also interested in developing novel lectin binding molecules. To simplify the oligosaccharide synthesis, we have developed novel synthetic protocols to ease the purification of the oligosaccharide from the reaction. Ionic liquid precipitation, C18 silica gel assisted purification and carbonyl cobalt resin facilitated purifications are three major strategies that have been successfully developed. Further, we have also developed efficient glycosylation strategies, which facilitate the synthesis of β-2-de-O-glycoside, L-glycoside and LPS.
