  4. 2. Diaryliodonium Salts : Development of Synthetic Methodologies and α-Arylation of Enolates

    Author : Marcin Bielawski; Berit Olofsson; Antonio Togni; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Hypervalent Iodine Compounds; One-Pot Synthesis; Regiospecific Synthesis; Aromatic Substitution; Aryl Iodides; Arenes; Boronic Acids; Heteroaromatics; Arylations; Reaction Mechanisms; Density Functional Calculations; Large Scale Synthesis; Organic synthesis; Organisk syntes; organisk kemi; Organic Chemistry;

    Abstract : This thesis describes novel reaction protocols for the synthesis of diaryliodonium salts and also provides an insight to the mechanism of α-arylation of carbonyl compounds with diaryliodonium salts.  The first chapter gives a general introduction to the field of hypervalent iodine chemistry, mainly focusing on recent developments and applications of diaryliodonium salts.

  5. 3. Synthesis of Ring-fused Peptidomimetics : Interacting with Amyloid Fibrils

    Author : Dan E. Adolfsson; Fredrik Almqvist; Anna Linusson; Morten Grötli; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; organic chemistry; synthesis; peptidomimetics; thiazoline fused 2-pyridones; Alzheimer s disease; Parkinson s disease; Amyloid; Amyloid-beta; alfa-Synuclein; method development; organisk kemi; Organic Chemistry;

    Abstract : Parkinson's and Alzheimer's disease are the two most common neurological disorders in humans. Both conditions involve progressive death of neurons in the central nervous system, decline in bodily functions and eventually (and invariably), death. So far, no cure exists and the available treatments can only ease symptoms. READ MORE

  6. 4. Synthesis and investigation of bacterial effector molecules

    Author : Michael Franz Albers; Christian Hedberg; Christian Hackenberger; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; bacterial effectors; organic synthesis; Legionella; PTM; peptide synthesis; nucleotide chemistry; Biorganic Chemistry; bioorganisk kemi;

    Abstract : During infections, bacterial microorganisms initiate profound interactions with mammalian host cells. Usually defense mechanisms of the host destroy intruding bacteria in rapid manner. However, many bacterial pathogens have evolved in a way to avoid these mechanisms. READ MORE

  7. 5. Leukocyte sequestration associated with inflammation : mechanisms and modulations

    Author : Kristina Nyhlén; Åke Ryrfeldt; Linköpings universitet; []
    Keywords : MEDICINE; MEDICIN;

    Abstract : Inflammationsreaktionen är kroppens första försvar mot främmande partiklar t ex bakterier. Det är en komplex reaktion som bl a karakteriseras av att vita blodkroppar dras till det inflammerade området och att vätskao i blodet lättare tar sig igenom kärlväggen till vävnaden dvs det svullnar.
