2. 1. Potent inhibitors of uropathogenic E. coli papG adhesins; Synthesis, conformational studies and biological evaluation of galabiose derivatives and synthesis of glycosphingolipid analogues

   Author : Jörgen Ohlsson; Centrum för analys och syntes; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Organic chemistry; Organisk kemi; Glycosphingolipid analogue; PapG adhesin; Esherichia coli; Galabiose analogues; Inhibitors; Glycoconjugates;

   Abstract : The importance of carbohydrates in biological systems has become evident during the last fifty years. It is well known that pathogenic bacteria and viruses attach to glycoconjugates present at mammalian cell surfaces, and that this attachment is a prerequisite for the later stages of infection.

4. 2. The importance of Escherichia coli fimbriae in urinary tract infection

   Author : Mats Söderhäll; Karolinska Institutet; Karolinska Institutet; []
   Keywords : ;

   Abstract : Urinary tract infection (UTI) is a major bacterial infectious disease among women. Uropathogenic Escherichia coli is the most dominant causative agent. READ MORE

5. 3. Synthesis, conformational analysis, and biological evaluation of peptides from E. coli P pilus proteins

   Author : Katarina Flemmer Karlsson; Centrum för analys och syntes; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NMR spectroscopy; CD spectroscopy; peptide structure; ELISA; solid-phase peptide synthesis; peptide; P pili; chaperone; Organic chemistry; Organisk kemi;

   Abstract : Many bacteria utilize hairlike protein appendages (pili) to attach themselves to mucosal cell surfaces in the host organism. The pilus is assembled from protein subunits synthesized inside the bacteria and transported to the outer cell wall for incorporation into the growing pilus. READ MORE

6. 4. Escherichia coli Fimbriae, Bacterial Persistence and Host Response Induction in the Human Urinary Tract

   Author : Göran Bergsten; immunologi och glykobiologi - MIG Avdelningen för mikrobiologi; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; mykologi; virologi; bakteriologi; Mikrobiologi; mycology; virology; bacteriology; Microbiology; IL-8; IL-6; neutrophils; GFP; mucosal host response; Type 1 fimbriae; P fimbriae; adherence; virulence factors; regulation; deliberate colonisation; Escherichia coli 83972; Urinary tract infection; asymptomatic bacteriuria;

   Abstract : Urinary tract infections (UTI) are among the most common bacterial infections in humans. Symptomatic UTIs may be acute, recurrent or chronic but the most frequent form of UTI is asymptomatic bacteruria (ABU). In ABU, the mucosa remains inert, despite the presence of large bacterial numbers in urine. READ MORE

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

   Author : Andreas Larsson; Jan Kihlberg; Fredrik Almqvist; Mats Larhed; Umeå universitet; []
   Keywords : 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;

   Abstract : 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.
