  1. 1. Carborane Derivatives for Nuclide Therapy and Imaging : Synthesis and Radio-labelling

    Författare :Karl Johan Winberg; Stefan Sjöberg; Kálmán Szabó; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Organic chemistry; Organisk kemi; Organic chemistry; Organisk kemi; organisk kemi; Organic Chemistry;

    Sammanfattning : This thesis describes synthesis and radiohalogenation of closo-carborane and nido-carborate derivatives for application in nuclide therapy and imaging. The work could be divided in to four sections. LÄS MER

  3. 2. Development of new Fluorination Methods Directed to Fluorine-18 Labelling

    Författare :Miguel Ángel Cortés González; Kálmán J. Szabó; Guosheng Liu; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; fluorine; fluorine-18; late-stage; labelling; nucleophilic; electrophilic; fluorination; positron emision tomography; PET; hypervalent iodine; benziodoxole; metal-free; DBU; copper; palladium; rhodium; carbene; organisk kemi; Organic Chemistry;

    Sammanfattning : This thesis deals with the development of new fluorination reactions and their application to fluorine-18 labelling. Fluorine-18 labelled compounds are employed as tracers in Positron Emission Tomography (PET), which is a powerful non-invasive imaging method in medical diagnostics. LÄS MER

  4. 3. Synthesis of Organofluorine Compounds and Allenylboronic Acids - Applications Including Fluorine-18 Labelling

    Författare :Denise N. Meyer; Kálmán J. Szabó; Dominique Cahard; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; boron; allenylboronic acid; BINOL; homopropargyl alcohol; organocatalyst; organoboron; organofluorine; fluorine; fluorine-18; late-stage; labelling; labeling; nucleophilic; electrophilic; fluorination; positron emision tomography; PET; radiotracer; hypervalent iodine; benziodoxole; benzoxazepines; diaryliodonium salt; metal-free; neutrophil elastase; NE; neutrophil elastase inhibitor; trifluoromethylation; trifluoromethylthiolation; difluoro enol silyl ethers; organisk kemi; Organic Chemistry;

    Sammanfattning : This work is focused on two areas: the chemistry of organofluorine and organoboron compounds. In the first chapter, a copper-catalysed synthesis of tri- and tetrasubstituted allenylboronic acids is presented. Extension of the same method leads to allenylboronic esters. LÄS MER

  5. 4. Design and Synthesis of 11C-Labelled Compound Libraries for the Molecular Imaging of EGFr, VEGFr-2, AT1 and AT2 Receptors : Transition-Metal Mediated Carbonylations Using [11C]Carbon Monoxide

    Författare :Ola Åberg; Bengt Långström; Nicholas Long; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; [11C]carbon monoxide; isotopic labelling; PET; acrylamide; EGFR; VEGFR-2; 11C; Organic chemistry; Organisk kemi; Organic Chemistry; Organisk kemi; Organic Pharmaceutical Chemistry; Organisk farmaceutisk kemi;

    Sammanfattning : This work deals with radiochemistry and new approaches to develop novel PET tracers labelled with the radionuclide 11C.Two methods for the synthesis of 11C-labelled acrylamides have been explored. LÄS MER

  7. 5. Tumour Targeting using Radiolabelled Affibody Molecules : Influence of Labelling Chemistry

    Författare :Mohamed Altai; Vladimir Tolmachev; Jacques Barbet; Uppsala universitet; []
    Nyckelord :HER2; Affibody molecule; Radionuclide molecular maging; Targeted radionuclide therapy; Labeling chemistry;

    Sammanfattning : Affibody molecules are promising candidates for targeted radionuclide-based imaging and therapy applications. Optimisation of targeting properties would permit the in vivo visualization of cancer-specific surface receptors with high contrast. In therapy, this may increase the ratio of radioactivity uptake between tumour and normal tissues. LÄS MER
