1. Synthesis of Bacterial Oligosaccharides from N. meningitidis and Mechanistic Details of Stereoselective Glycosylations Using a Novel Bicyclic Donor
Sammanfattning : This thesis includes two parts. The first part, comprising Chapters 3, 4 and 5, describes the synthesis of bacterial oligosaccharides. In Chapters 3 and 4, the synthesis of branched and phosphorylated oligosaccharide structures corresponding to inner core epitopes of the lipopolysaccharide (LPS) of the Gram-negative bacteria N. LÄS MER
2. Syntheses of naturally occurring fatty acid esters of sucrose and heptose-containing oligosaccharides found in the Salmonella Ra core
Sammanfattning : Nine sucrose esters, acylated in the glucopyranosyl moiety, have been synthesized from the same precursor, 3-0-allyl-3',4',6'-tri-0-benzyl-4,6-0- (4-metoxybenzylidene)sucrose. The sucrose esters synthesized include the major compounds found in tobacco and potato plants, i. e. LÄS MER
3. Synthesis of LPS epitopes containing Kdo, L-, and D-Glycero-D-manno-heptose to be used in potential conjugate vaccines against Haemophilus species
Sammanfattning : .... LÄS MER
4. Synthesis of Oligosaccharides from the Inner Core Structure of Haemophilus Influenzae and Neisseria meningitidis Lipopolysaccharides
Sammanfattning : This thesis describes the synthesis of oligosaccharides corresponding to different parts of the lipopolysaccharide (LPS) inner core structure from Haemophilus influenzae and Neisseria meningitidis. Chapter 2 describes the synthesis of a protected trisaccharide common to H. influenzae and N. LÄS MER
5. Structural and genetic characterization of lipopolysaccharides extracted from disease causing non-typeable Haemophilus influenzae strains
Sammanfattning : This thesis deals with the structure and genetic blueprint of lipopolysaccharides (LPS) expressed by the Gram-negative bacterium Haemophilus influenzae (H.influenzae). H. influenzae is an opportunistic pathogen that regularly colonizes the upper respiratory tract and exists in encapsulated (typeable) or nonencapsulated (non-typeable) forms (NTHi). LÄS MER
