  Synthesis of Glycoconjugate Vaccines against Shigella dysenteriae Type 1

  摘要：

  Syntheses of a hexadecasaccharide and smaller fragments corresponding to one-four repeating units of the O-specific polysaccharide of Shigella dysenteriae type 1 are reported in a reactive aglyconlinked from. Two tetrasaccharide donor/acceptor repeating units were assembled from monosaccharide precursors in a stepwise fashion and used in a linear, iterative manner to construct the higher-membered saccharides using Schmidt's glycosylation technique that proved superior to others tested. Single-point attachment of the saccharides to human serum albumin, using a secondary heterobifunctional spacer, afforded a range of glycoconjugates for a detailed evaluation of their immunological characteristics.

  Hexa- to tridecasaccharides corresponding to the O-specific polysaccharide (O-SP) of the Gram-negative bacterium Shigella dysenteriae type 1 were synthesized in solution phase. The syntheses utilized tetra-, octa-, and dodecasaccharide intermediates that represent one to three contiguous tetrasaccharide repeating units of the O-SP [Synlett2003, 743]. These compounds were glycosylated with mono-, di-
