21. Pilicides and Curlicides : Design, synthesis, and evaluation of novel antibacterial agents targeting bacterial virulence
Sammanfattning : New strategies are needed to counter the growing problem of bacterial resistance to antibiotics. One such strategy is to design compounds that target bacterial virulence, which could work separately or in concert with conventional bacteriostatic or bactericidal antibiotics. LÄS MER
22. Synthesis of O-linked Carbasugar Analogues of Galactofuranosides and N-linked Neodisaccharides
Sammanfattning : In this thesis, carbohydrate mimicry is investigated through the syntheses of carbohydrate analogues and evaluation of their inhibitory effects on carbohydrate-processing enzymes. Galactofuranosides are interesting structures because they are common motifs in pathogenic microorganisms but not found in mammals. M. LÄS MER
23. Synthesis of xyloglucan oligo- and polysaccharides with glycosynthase technology
Sammanfattning : Xyloglucans 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.

24. Development of organocatalytic asymmetric transformations
Sammanfattning : The ability of amino acids and amino acid derivatives to mediate various organocatalytic asymmetric transformations has been investigated and applied in the development of various reactions. This work describes the development of a direct catalytic asymmetric α-aminomethylation of ketones and aldehydes, a catalytic asymmetric aziridination, hydrophosphination and amination of α,β-unsaturated aldehydes.
