  The synthesis of biotinylated carbohydrates as probes for carbohydrate-recognizing proteins

  摘要：

  The intimate involvement of carbohydrate-protein interactions in a number of important biological processes has prompted several research efforts towards developing new met:hods of investigating these glycobiological interactions. Biotinylated oligosaccharides are emerging as a new and powerful tool in this area of research, primarily due to their high affinity towards streptavidin and their ease of immobilization on matrices. Here we describe a novel synthetic approach towards biotinylated saccharides which incorporate a UV absorbing group into the final compounds. The synthetic strategy described is applicable to a variety of saccharides, with examples of biotinylated mono-, di-, and trisaccharides being prepared with overall high efficiency.
