Recent Progress in the Solid-phase Synthesis of Glycopeptide

The recent understanding of the biological role of glycoproteins has brought about a demand for the highly homogeneous glycopeptides as the functional model for glycoproteins. Thus, much efforts have been made to establish easy and efficient method for glycopeptide synthesis. In this paper, we briefly review the recent advances in the synthesis of O- and N-linked glycopeptide based on the solid-phase method. In O-glycopeptide section, the preparation of glycosylated amino acid units with mucin type and other O-linked carbohydrate chains and their use for solid-phase synthesis are summarized. Other approaches, such as the glycosylation of resin bound peptide are also overviewed. In N-glycopeptide section, the synthesis using glycosylated amino acid units as well as other methods are described..
