  1. 1. Antiadhesive agents targeting uropathogenic Escherichia coli : Multivariate studies of protein-protein and protein-carbohydrate interactions

    Författare :Andreas Larsson; Jan Kihlberg; Fredrik Almqvist; Mats Larhed; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Organic chemistry; Antibacterial; pili; antiadhesive agents; structure based design; statistical molecular design; 2-pyridone; amino acid derivative; galabiose; enaminone; SPR; ELISA; QSAR; Organisk kemi; Organic chemistry; Organisk kemi; organisk kemi; Organic Chemistry;

    Sammanfattning : This thesis describes studies directed towards development of novel antiadhesive agents, with particular emphasis on compounds that prevent attachment of bacteria to a host-cell. Three different proteins involved in the assembly or function of adhesive pili in uropathogenic Escherichia coli have been targeted either by rational structure based design or statistical molecular methods.

  3. 2. Hemicelluloses and other Polysaccharides for Wood Adhesive Applications

    Författare :Emelie Norström; Eva Malmström; Orlando Rojas; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fiber- och polymervetenskap; Fibre and Polymer Science;

    Sammanfattning : The growing environmental awareness has led to an increased interest in bio-based polymers as replacement for fossil-based materials. The purpose of the work described in this thesis was to investigate the possibility of using hemicelluloses and other polysaccharides as replacement for fossil-based polymers in wood adhesives.

  4. 3. Endothelial cell interactions with neutrophils : studies of adhesion and effects of lipoxygenase metabolites and antirheumatic drugs

    Författare :Mikael Heimbürger; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :adhesion; auranofin; endothelium; gold sodium thiomalate; leukotrienes; lipoxins; neutrophils; PPAR; prednisolone;

    Sammanfattning : Inflammation is a process of vital importance in the defence and elimination of microorganisms as well as in the repair of the damaged tissue. However, inadequate or excessive inflammation leads to inflammatory diseases such as rheumatoid arthritis. LÄS MER

  5. 4. Abdominal adhesions - clinical impact and experimental prevention

    Författare :Bobby Tingstedt; Lund Kirurgi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Surgery; orthopaedics; anastomotic healing; adhesion prevention; polypeptides; long term follow-up; cost; non-specific abdominal pain; abdominal adhesions; small bowel obstruction; ortopedi; traumatologi; Kirurgi; traumatology; burst pressure;

    Sammanfattning : Intraabdominal adhesions are formed after most operations and a limited number of studies have to examine the long-term spectrum of adhesion-related disorders and the cost associated with this. Only a few numbers of antiadhesive agents are available which, however, do not decrease the actual morbidity that follows intraabdominal adhesions, such as small bowel obstruction, infertility and pain.

  7. 5. Synthesis and functionalization of ring-fused 2-pyridones : Targeting pili formation in E. coli

    Författare :Nils Pemberton; Fredrik Almqvist; Oliver Kappe; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; 2-pyridone; acylketene; antibacterial; biofilm inhibitor; Mannich; Micro-wave-assisted chemistry; peptidomimetic; virulence.; Organic synthesis; Organisk syntes;

    Sammanfattning : Bicyclic dihydrothiazolo fused 2-pyridones have been studied as a new class of antibacterial agents, termed pilicides, that target the formation of adhesive bacterial surface organelles (pili) in pathogenic bacteria. Synthetic methods to further functionalize the bicyclic 2-pyridone scaffold have been developed in order to increase water-solubility and thereby facilitate biological evalua-tions. LÄS MER
