  1. 1. Copper(II) Azido Complexes: Synthesis, X-ray structures, thermal and magnetic properties

    Författare :Al-Shimaà A A Massoud; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Cu II complexes; bridging µ1; quinoxaline; 2; pyrazinetetrazolate; quinolinecarboxylate; 1–N3; 5-dimethylpyrazine; ferromagnetic interactions;

    Sammanfattning : This thesis focuses on the synthesis and X-ray structure analysis of seven copper(II) and one cobalt(II) azido coordination polymer with quinoline and pyrazine derivatives as bridging co-ligands. The synthesis of these complexes were done by direct mixing of the metal salt (Cu(NO3)2 and CoCl2) and the organic ligand (pyrazinecarbonitrile, quinoxaline, quinoline-4-carboxylic acid and 2,5-dimethylpyrazine) solutions followed by the dropwise addition of aqueous sodium azide (NaN3) with continuous stirring.

  2. 2. Synthesis of Structures Related to the Capsular Polysaccharide of Neisseria meningitidis Serogroup A and to Mycothiol

    Författare :Rikard Slättegård; Stefan Oscarson; Andrei Nikolaev; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Neisseria meningitidis; Capsular polysaccharide; Mycobacterium tuberculosis; Mycothiol; Organic chemistry; Organisk kemi; Organic Chemistry; organisk kemi;

    Sammanfattning : This thesis describes the synthesis of structures related to the capsular polysaccharide of Neisseria meningitidis serogroup A and the synthesis of analogues of mycothiol, a compound produced by Mycobacterium tuberculosis. The first part of the thesis describes the synthesis of structural elements present in the native capsular polysaccharide of Neisseria meningitidis serogroup A. LÄS MER

  3. 3. NADH:quinone oxidoreductase: the black box of the respiratory chain

    Författare :Robert Roth; Biokemi och Strukturbiologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NADH:quinone oxidoreductase; Complex I; electron transport; membrane protein; ubiquinone; respiratory chain; respiration; metabolism; Metabolism; Biokemi; Biochemistry;

    Sammanfattning : Complex I or NADH:quinone oxidoreductase the largest, most complex and least understood of the five membrane-bound enzyme complexes constituting the mitochondrial respiratory chain. The enzyme is present in all types of organisms, from bacteria to mammals. LÄS MER

  4. 4. Synthesis of oligosaccharides related to the capsular polysaccharide of Neisseria meningitidis serotype A

    Författare :Peter Teodorovic; Stefan Oscarson; Mikael Elofsson; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Organic chemistry; Organisk kemi;

    Sammanfattning : In order to find suitable stable vaccine candidates against Neisseria meningitidis group A, several structures related to the capsular polysaccharide have been synthesised. The first part of the thesis describes the synthesis of C-phosphonate analogues starting from glucose. LÄS MER

  5. 5. Synthesis of lactosamine-containing carbohydrate structures and development for their easy assembly and conjugation

    Författare :Therese Buskas; Robert Madsen; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Organic Chemistry; organisk kemi;

    Sammanfattning : This thesis is based on four publications. The first chapter describes preparation of anomerically pure thioethyl-, thiophenyl-, and n-pentenyl 2-azido-2-deoxy glycosyl building blocks from easily accessible per-acetylated glycosamines. LÄS MER
