| Research Abstract |
In this research project, a new type of glycoconjugates, namely, "fullerene g ycoconjugates ' was designed and developed. The C60 conjugates are composed of biologically active active giycosides introduced onto the surface via an N-glycoside linkage. The different property of the two molecules regarding from both physicchemical and biological aspects is expected to induce a novel class of biologically active compounds.
Prior to the synthesis of the'Tullerene glycoconjugates", an efficient glycosylation method was deveioped, which involved the use of new thio-glycosyl donors and galactosyltransferase. The new thio-glycosyl donor was applied conveniently to the formation of globotn- and biosides possessing high biological potential to trap Shiga toxins and deactivate the toxins. A bovine galactosyltransferase was found to catalyse a novel class of enzymic reactions applicable to non-natural L-sugars and acyclic substrates.
Several types of biologiclaly active saccharides were coupled with C60 fullerene via thermal couplmg between a glycoylazide and C60. The derived fullerene glycococonjugates as well as fullerenol conjugates were water-miscible and proved to show high biological potential to block carbohydrate-protein binding involved in many biological phenomena.
