  4. 18. Chemical Synthesis of Affibody Molecules for Protein Detection and Molecular Imaging

    Författare :Torun Ekblad; Amelie Eriksson Karlström; Per-Åke Nygren; Harald Kolmar; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Affibody; peptide synthesis; protein detection; molecular imaging; Bioengineering; Bioteknik;

    Sammanfattning : Proteins are essential components in most processes in living organisms. The detection and quantification of specific proteins can be used e.g. as measures of certain physiological conditions, and are therefore of great importance. LÄS MER

  5. 19. New Reactivity in Diaryliodonium Salt Chemistry

    Författare :Erika Linde; Berit Olofsson; Thomas Wirth; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Organic Chemistry; organisk kemi;

    Sammanfattning : Diaryliodonium salts (Ar2IX) have emerged as versatile multi-purpose reagents with desirable properties such as easy accessibility, low toxicity and applicability under mild and metal-free reaction conditions. Despite displaying broad utility in arylations of both carbon and heteroatom nucleophiles, the overall sustainability of these protocols is compromised by featuring poor atom economy due to the formation of stochiometric iodoarene byproducts.
