Synthesis of ω-(methoxycarbonyl)alkyl and 9-(methoxycarbonyl)-3,6-dioxanonyl glycopyranosides for the preparation of carbohydrate-protein conjugates
摘要:
Omega-(Methoxycarbonyl)alkyl glycopyranosides of D-mannose having C4, C-7, C-9, C-12, and C-15 carbon chains, L-fucose and 2-acetamido-2-deoxy-D-mannose having C-7 and C-9 carbon chains. D-xylose and 2-acetamido-2-deoxy-L-fucose having a C-9 carbon chian, and 9-(methoxycarbonyl)-3,6-dioxanoyl glycopyranosides of D-mannose. 2-acetamido-2-deoxy-D-mannose, and L-fucose were' synthesized as intermediates for coupling to human serum albumin in order to examine the effect of chain length and hydrophobicity of the spacer arm on the binding specificity of lectins. 8-(Methoxycarbonyl)octyl glycosides of beta-D-Man-(1 --> 2)-alpha-D-Man, alpha-D-Man-(1 --> 2)-alpha-D-Man, alpha-D-ManNAc-(1 --> 2)-alpha-D-Man, beta-D-GlcNAc-(1 --> 2)-alpha-D-Man, and their 6-O-positional isomers, beta-D-Man-(1 --> 6)-alpha-D-Man, alpha-D-Man-(1 --> 6)-alpha-D-Man, alpha-D-ManNAc-(1 --> 6)-alpha-D-Man, and beta-D-GlcNAc-(1 --> 6)-alpha-D-Man, were also synthesized.
Synthetic yeast oligomannosides as biological probes: α-d-Manp (1→3) α-d-Manp (1→2) α-d-Manp and α-d-Manp (1→3) α-d-Manp (1→2) α-d-Manp (1→2) α-d-Manp as Crohn's disease markers
摘要:
The anti-Saccharomyces cerevisiae antibodies (ASCA) are markers for Crohn's disease used for diagnostic, phenotypic characterization and sero-epidermiological studies. Antibody detection is made by different immunoenzymatic tests using S. cerevisiae mannans which are both complex and poorly standardized antigens. Here we construct the major discriminating epitopes comprised within this antigen. When coupled to linker arm and a peptidic carrier to functionalize microtiter plates, they were able to discriminate serological responses between Crohn's disease and ulcerative colitis, another form of inflammatory bowel disease.

The present invention relates to dendrimers with a monosaccharide, oligosaccharide or polysaccharide terminal group, to their preparation method and their therapeutic uses, notably anti-inflammatory uses.
A pharmaceutical composition including a therapeutically effective amount of at least one oligomannoside produced by chemical synthesis which is homologous to a wall oligomannoside of an infectious organism or pathogen, or a derivative thereof, and a pharmaceutically acceptable vehicle.
