Texte intégralReversible polymers, or dynamic polymers, result from the reversible association of monomers using covalent (dynamic covalent polymers) or non covalent (supramolecular polymers) chemical bonds. As the polymerisation is reversible, the structure, the molecular weight distribution, and the composition of the polymer are susceptible to evolve even after polymerisation. According to their dynamic character this polymers are adaptative and can respond to an external stimuli (temperature, pH, presence of a molecular target) by a constitutional change, and so they can be considered as smart materials. Our goal was to prepare dynamic covalent polymers, based on reversible imine bonds formation (hydrazones or oximes), that are analogs of natural polysaccharides. This dynamic glycopolymers could be interesting as materials, and have biorecognition properties combined with the possibility to adapt their sequence and composition in presence of a biological target

Texte intégralCarbohydrates are a complex group of biomolecules with a high structural diversity. Their almost omnipresent occurrence has generated a broad field of research in both biology and chemistry. This thesis focuses on three different aspects of carbohydrate chemistry, synthesis, structure elucidation and the conformational analysis of carbohydrates.
The first paper describes the synthesis of a penta- and a tetrasaccharide related to the highly branched capsular polysaccharide from Streptococcus pneumoniae type 37. In the second paper, the structure of the O-antigenic repeating unit from the lipopolysaccharide of E. coli 396/C1 was determined along with indications of the structure of the biological repeating unit. In addition, its structural and immunological relationship with E. coli O126 is discussed. In the third paper, partially protected galactopyranosides were examined to clarify the origin of an intriguing 4JHO,H coupling, where a W-mediated coupling pathway was found to operate. In the fourth paper, the conformation of methyl a-cellobioside is studied with a combination of molecular dynamics simulations and NMR spectroscopy. In addition to the expected syn-conformation, detection and quantification of anti-ø and anti-ψ conformers was also possible.

Gullfot, Fredrika. « Synthesis of xyloglucan oligo- and polysaccharides with glycosynthase technology ». Licentiate thesis, KTH, School of Biotechnology (BIO), 2009. http://urn.kb.se/resolve?urn=urn:nbn:se:kth:diva-10178.
Texte intégralXyloglucans are polysaccharides found as storage polymers in seeds and tubers, and as cross-linking glycans in the cell wall of plants. Their structure is complex with intricate branching patterns, which contribute to the physical properties of the polysaccharide including its binding to and interaction with other glycans such as cellulose.
Xyloglucan is widely used in bulk quantities in the food, textile and paper making industries. With an increasing interest in technically more advanced applications of xyloglucan, such as novel biocomposites, there is a need to understand and control the properties and interactions of xyloglucan with other compounds, to decipher the relationship between xyloglucan structure and function, and in particular the effect of different branching patterns. However, due to the structural heterogeneity of the polysaccharide as obtained from natural sources, relevant studies have not been possible to perform in practise. This fact has stimulated an interest in synthetic methods to obtain xyloglucan mimics and analogs with well-defined structure and decoration patterns.
Glycosynthases are hydrolytically inactive mutant glycosidases that catalyse the formation of glycosidic linkages between glycosyl fluoride donors and glycoside acceptors. Since its first conception in 1998, the technology is emerging as a useful tool in the synthesis of large, complex polysaccharides. This thesis presents the generation and characterisation of glycosynthases based on xyloglucanase scaffolds for the synthesis of well-defined homogenous xyloglucan oligo- and polysaccharides with regular substitution patterns.

Texte intégralThis thesis reports the preparation and characterization of new rod-coil amphiphiles functionalized with oligo- and polysaccharides through Huisgen 1,3-dipolar cycloaddition reactions between species functionalized by an azide group on one side and an terminal alkyne on the other catalyzed by copper. The amphiphiles were synthesized and characterized based on different hydrophobic parts conjugated with the polymer poly(ethylene oxide) PEO with a hydrophilic spacer arm and the oligo- and polyssaccharides 2-propargyl-2-acetamido-2-deoxy-β-D-glucopyranose (GlcNAc) and propargyl β-D-galactopyranosyl-(14)-β-D-glucopyranose (Lac). The amphiphiles synthesized were characterized in terms of their chemical structure and composition through nuclear magnetic resonance (NMR), Fourier transform infrared (FTIR) spectroscopy, mass spectroscopy (MALDI-TOF-MS and ESI-MS) and high resolution mass spectroscopy (HRMS). After the dissolution in water, the amphiphiles self-associate in highly regular micelles with an average diameter of 2RH ~ 10 nm. Dynamic light scattering (DLS), transmission electron microscopy (TEM) and small angle x-ray scattering (SAXS) were used in order to investigate the structure and dynamics of these saccharide amphiphiles. The presence of carbohydrate epitopes on the surface of the micelles and their bioavailability for the segmentation of lectin were also demonstrated by DLS. Specific interactions of GlcNAc and Lac residues with lectins from wheat germ agglutinin (WGA) and peanut agglutinin (PNA), respectively, reveal the potential applications of such amphiphilic derivatives of carbohydrates as vectorizing systems, both simple and specific to a drug delivery site
