1. Development of new Fluorination Methods Directed to Fluorine-18 Labelling
Abstract : 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. READ MORE

2. Synthesis of Organofluorine Compounds and Allenylboronic Acids - Applications Including Fluorine-18 Labelling
Abstract : 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. READ MORE

3. One-click away from higher contrast : Improvements to peripheral clearance for same-day immunoPET in Alzheimer’s disease
Abstract : The brain is a challenging target for antibody-based positron emission tomography (immunoPET) to image amyloid-beta (Aβ). Antibodies detect pathology with high sensitivity, but due to their size and biological half-life, they cause a high background radiation, if radiolabelled. READ MORE

4. Development of novel fluorine-18 labeled PET radioligands for monoamine oxidase B (MAO-B)
Abstract : Monoamine oxidases (MAO-A and MAO-B) are important enzymes regulating the levels of monoaminergic neurotransmitters. Selective and irreversible MAO-B inhibitors such as L-deprenyl and rasagiline are clinically used for the treatment of psychiatric and neurological disorders. READ MORE

5. Preclinical PET imaging of Alzheimer's disease progression
Abstract : Amyloid PET imaging with [11C]PIB enabled detection of Aβ for the first time in vivo. However, [11C]PIB is a small molecule that binds only the insoluble Aβ plaque. Rather, the soluble Aβ aggregates are considered the cause of Alzheimer’s disease (AD). READ MORE
