When ambiguities arise in the NMR interpretation, the use of other data will be discussed.The glycobiology of brain tumors disease relevance and therapeutic potential.The oligosaccharides that decorate cell surface glycoconjugates play important roles in intercellular recognition and cell-extracellular matrix interactions, and thus the regulation of cellular migration, metastasis and invasivity. Virtually all tumor cells display aberrant cell-surface glycosylation patterns brought about by alterations in their biosynthetic machinery. This holds true for highly invasive, malignant brain tumors as well as tumor cells that metastasize to the brain. The field of glycobiology is well established with essentially all of the biochemical pathways for oligosaccharide metabolism characterized and all of the 'glycogenes' involved in these pathways cloned.

Yet there has been a paucity of progress toward the development of therapeutics. However, recent studies aimed at controlled glycosylation of therapeutic antibodies and mucins with anticancer vaccine potential, the emergence of new and highly sensitive tools for the identification of tumor-associated biomarkers and the manipulation of the expression of glycogenes that inhibit brain tumor invasivity have emerged. The opportunity now exists to answer questions as to how glycogenes are regulated at the genomic and transcriptomic level and how altered glycogene expression patterns lead to altered cell surface glycoconjugates. These studies should lead to the development of ways to directly regulate tumor cell glycogene expression, which should have significant Carbohydrate fluorescence electrophoresis. Oligosaccharide analysis with [Synthesis of oligosaccharide fragments of mannan from Candida albicans cell alpha-D-mannopyranosyl-(1--2)-alpha-D-mannopyranosyl-(1--2)-alpha-D-mannopyra-nosyl-(1--2)-alpha-D-mannopyranose, alpha-D-mannopyranosyl-(1--3)-alpha-D-mannopyranosyl-(1--2)-alpha-D-mannopyranosyl-(l alpha-D-mannopyranosyl-(1--2)-[alpha-D-mannopyranosyl-(1--3)]-alpha-D-mannopyranosyl-(1--2)-alpha-D-mannopyranosyl-(1--2)-alpha-D-mannopyranose were efficiently synthesized starting from ethyl 2-O-acetyl(benzoyl)-3,4,6-tri-O-benzyl-l-thio-alpha-D-mannopyranoside, ethyl 4,6-di-O-benzyl-2-O-benzoyl-1-thio-alpha-D-mannopyranoside, ethyl 4,6-di-O-benzyl-2,3-di-O-benzoyl-l-thio-alpha-D-mannopyranoside, and 2,3,4,6-tetra-O-benzoyl-alpha-D-mannopyranosyl bromide. The oligosaccharide chains synthesized correspond to the three structural types of side chains of mannan from Candida albicans cell wall. 2'-Fucose lactose of the third pentasaccharide with bovine serum albumin was prepared using the squarate method.

Lignan oligosaccharide esters from Eritrichium rupestre.Three new lignan oligosaccharide esters, rupestrin A (1), rupestrin B (2), and rupestrin C (3), were isolated from the ethanol extract of Eritrichium rupestre. Their structures were elucidated on the basis of spectroscopic and chemical Improving vaccines against Streptococcus pneumoniae using synthetic glycans.Kaplonek P(1)(2), Khan N(1), Reppe K(3)(4), Schumann B(1), Emmadi M(1), Lisboa MP(1), Xu FF(1), Calow ADJ(1), Parameswarappa SG(1), Witzenrath M(3)(4), Pereira corporate member of Freie Universität Berlin, Humboldt-Universität zu Berlin and Berlin Institute of Health, 117 Berlin, Germany.Universitätsmedizin Berlin, corporate member of Freie Universität Berlin, Humboldt-Universität zu Berlin and Berlin Institute of Health, 117 Berlin, Streptococcus pneumoniae remains a deadly disease in small children and the elderly even though conjugate and polysaccharide vaccines based on isolated capsular polysaccharides (CPS) are successful. 2'-fucosyllactose that cause infection are used in vaccines around the world, but differences in geographic and demographic serotype distribution compromises protection by leading vaccines. The medicinal chemistry approach to glycoconjugate vaccine development has helped to improve the stability and immunogenicity of synthetic vaccine candidates for several serotypes leading to the induction of higher levels of specific protective antibodies.

Here, we show that marketed CPS-based glycoconjugate vaccines can be improved by adding synthetic glycoconjugates representing serotypes that are not covered by existing vaccines. Combination Prevnar13 (13-valent) and Synflorix (-valent) yields improved 15- and 13-valent conjugate vaccines, respectively, in rabbits. A pentavalent semisynthetic glycoconjugate vaccine containing five serotype antigens (sPCV5) elicits antibodies with strong in vitro opsonophagocytic activity.
