1. Synthesis of Orthogonally Functionalized Oligosaccharides for Self-assembled Monolayers and as Multimodal Tools in Chemical Biology
Sammanfattning : This thesis covers different topics in the field of synthetic organic chemistry combined with the field of surface science and glycobiology.First, the text presents a series of orthogonally protected oligosaccharides (tri-, penta-, and heptasaccharides) of varying length and structures, which are synthesized with the aim of developing novel heterobifunctional biocompatible cross-linkers.

2. Development of strategies for construction of thioglycoside building blocks corresponding to repeating triads of Cryptococcus neoformans GXM capsular polysaccharide
Sammanfattning : This thesis focuses on the development of methods for synthesis of thioglycoside building blocks corresponding to the repeating units of the capsular polysaccharide (CPS) of Cryptococcus neoformans, an opportunistic fungal pathogen. The building blocks are suitable for construction of large synthetic oligosaccharides related to the native CPS-structures which are to be used in biological studies in order to identify protective epitopes with the aim to develop a glycoconjugate vaccine against C.

3. Computational analysis of oligosaccharide conformations – methodological development, applied studies, and design of glycomimetics
Sammanfattning : Carbohydrates are the most abundant class of biomolecules. Besides their roles as structural elements and energy storage, they are involved in signaling and recognition processes. Their functions and activities depend on their preferred conformations. LÄS MER
4. Synthesis of phytoalexin-elicitor active oligosaccharides and stereocontrolled sialylation using thioglycosides
Sammanfattning : .... LÄS MER
5. Synthesis of some oligosaccharide fragments of biological and chemical interest using thioglycosides
Sammanfattning : This thesis describes the synthesis of oligosaccharide derivatives corresponding to the repeating unit of the O-antigen from two different bacteria, Shigella dysenteriae type 1 and Salmonella thompson serogroup Ci, and fragments thereof. Synthesis of a decasaccharide of chemical interest for studying carbohydrate dynamics in elongated molecules is also described. LÄS MER
