• Synthesis of phosphorylated 3,4-branched trisaccharides corresponding to LPS inner core structures of Neisseria meningitidis and Haemophilus influenzae
  作者：Johan D.M. Olsson、Stefan Oscarson

  日期：2010.7

  spacer-equipped protected derivative of the common 3,4-branched diheptoside trisaccharide structure of the lipopolysaccharide core of Neisseria meningitidis and Haemophilus influenzae has been synthesized. The protecting group pattern installed allows regioselective introduction of phosphoethanolamine residues in the 3- and 6-position of the second heptose unit in accordance with native structures. From this intermediate

• Synthesis of a common tetrasaccharide motif of Haemophilus influenzae LPS inner core structures

  A conserved tetrasaccharide structure, L-glycero-α-D-manno-heptopyranosyl-(1→2)-(6-O-aminoethylphosphono-L-glycero-α-D-manno-heptopyranosyl)-(1→3)-[β-D-glucopyranosyl-(1→4)]-L-glycero-α-D-manno-heptopyranose, from the LPS inner core of Haemophilus influenzae has been synthesised as its ethylamino glycosides to allow later conjugations. Starting from a previously synthesised suitably protected trisaccharide intermediate, the third heptose and subsequently the spacer were introduced using thioglycoside donor chemistry. The phosphoethanolamine was formed employing a Boc-protected phosphoamidite. Final deprotection and conjugation to biotin gave conjugates that will be used to study the specificity of MAbs raised against native LPS structures.

  一种保守的四糖结构，L-glycero-α-D-manno-heptopyranosyl-(1→2)-(6-O-氨乙基膦酸-L-glycero-α-D-manno-heptopyranosyl)-(1→3)-[β-D-glucopyranosyl-(1→4)]-L-glycero-α-D-manno-heptopyranose，已从流感嗜血杆菌的LPS内核中合成为其乙基氨基糖苷，以便于后续的连接。从先前合成的适当保护的三糖中间体开始，引入了第三个七碳糖，随后通过硫糖苷供体化学引入了连接体。磷酸乙醇胺是通过使用Boc保护的磷酸酰胺化合物形成的。最后去保护并与生物素连接，得到的结合物将用于研究针对天然LPS结构的单克隆抗体的特异性。
• Zwitterionic Phosphodiester-Substituted Neoglycoconjugates as Ligands for Antibodies and Acute Phase Proteins
  作者：Karell Pérez Labrada、Sebastian Strobl、Barbara Eckmair、Markus Blaukopf、Zuzanna Dutkiewicz、Alba Hykollari、Daniel Malzl、Katharina Paschinger、Shi Yan、Iain B. H. Wilson、Paul Kosma

  Zwitterionic modifications of glycans, such as phosphorylcholine and phosphoethanolamine, are known from a range of prokaryotic and eukaryotic species and are recognized by mammalian antibodies and pentraxins; however, defined saccharide ligands modified with these zwitterionic moieties for high-throughput studies are lacking. In this study, we prepared and tested example mono- and disaccharides 6-substituted with either phosphorylcholine or phosphoethanolamine as bovine serum albumin neoglycoconjugates or printed in a microarray format for subsequent assessment of their binding to lectins, pentraxins, and antibodies. C-Reactive protein and anti-phosphorylcholine antibodies bound specifically to ligands with phosphorylcholine, but recognition by concanavalin A was abolished or decreased as compared with that to the corresponding nonzwitterionic compounds. Furthermore, in array format, the phosphorylcholine-modified ligands were recognized by IgG and IgM in sera of either non-infected or nematode-infected dogs and pigs. Thereby, these new compounds are defined ligands which allow the assessment of glycan-bound phosphorylcholine as a target of both the innate and adaptive immune systems in mammals.
• Synthesis of phosphorylated Neisseria meningitidis inner core lipopolysaccharide structures

  日期：2009.5

  A phosphoethanolamine-substituted tetrasaccharide structure, 2-aminoethyl 2-acetamido-2-deoxy-alpha-D-glucopyranosyl-(1 -> 2)-6-O-[2-(tert-butyloxycarbonylaminoethyl)-phophono]-L-glycero-alpha-D-manno-heptopyranosyl-(1 -> 3)-[beta-D-glucopyranosyl-(1 -> 4)]-L-glycero-alpha-D-manno-heptopyranoside,corresponding to the non-reducing part of the conserved part of Neisseria meningitidis lipopolysaccharides has been synthesized. Orthogonal protection of the phosphoethanolamino group in combination with the presence of a free amino-containing anomeric spacer allows conjugation to proteins to construct conjugate vaccine candidates. The tetrasaccharide is built up using a linear strategy, where the introduction Of the terminal alpha-GlcNAc moiety is performed using a 2-azido-thioglucoside as a donor and NIS/AgOTf as a promoter. The synthetic pathway includes tetrasaccharide intermediates appropriately designed to permit other phosphorylation patterns as well as elongation at the reducing end. (C) 2009 Elsevier Ltd.
