  1. 1. Photoinitiated Radical Carbonylation Using [11C]Carbon Monoxide : 11C-Labelling of Aliphatic Carboxylic Acids, Esters, and Amides

    Author : Oleksiy Itsenko; Bengt Långström; Tor Kihlberg; Chryssostomos Chatgilialoglu; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Organic chemistry; 11C-labelling; radicals; carbonylation; carbon monoxide; solvent effects; sensitizers; sulfoxides; WAY-100635; PET; Organisk kemi; Organic chemistry; Organisk kemi;

    Abstract : One-step photoinitiated free radical carbonylation was employed for the rapid (5–7 min) labelling of aliphatic carboxylic acids, esters, and amides with a short-lived positron emitter 11C (t½ = 20.3 min) at the carbonyl position. The labelled compounds were synthesized from alkyl iodides (0.05–0. READ MORE

  2. 2. Development of 18F- and 68Ga-Labelled Tracers : Design Perspectives and the Search for Faster Synthesis

    Author : Elisabeth Blom; Bengt Långström; Oleksiy Itsenko; Irina Velikyan; Farhad Karimi; Frank Rösch; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; PET; nucleophilic 18F-fluorination; perfluoro; F-SPE; molecular design; 68Ga; chelators; DOTA; NOTA; microwave; halogen exchange; harmine; biotin; RGD; VEGF; CRP; Chemistry; Kemi; Organisk kemi; Organic Chemistry;

    Abstract : This thesis deals with the design of 18F- and 68Ga-labelled positron emission tomography (PET) tracers and the development of technologies that enable faster and simpler preparation with high specific radioactivity. Techniques like microwave heating and reducing the concentrations of the precursor were investigated with this perspective. READ MORE
