Research Abstract |
In order to elucidate oligosaccharide functions, chemical synthesis of homogeneous glycoprotein was examined. For the synthesis of target glycoproteins, full-length glycosylpolypeptide chains was designed to divide into several segments and these were prepared by our improved and safe tert-Boc-SPPS. Glycopeptide-alpha-thioester and peptide-alpha-thioesters thus obtained were successfully coupled by repetitive native chemical ligation. Subsequent folding experiments of chemically synthesized homogeneous glycopeptide yielded correctly folded glycoproteins with native disulfide bond patterns. Using this method, erythropoietin, chemokine and lectin were successfully synthesized.
