    Abstract : 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. READ MORE

  4. 12. Drug purity determination by capillary electrophoresis : Practical and theoretical aspects on peak shape and resolution

    Author : Olle Stålberg; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Chemistry; Kemi; Chemistry; Kemi; analytisk farmaceutisk kemi; Analytical Pharmaceutical Chemistry;

    Abstract : Capillary electrophoresis was used for separation and determination ofdrugs. Structural analogues, enantiomers and rotamers were separated usingderivatized β-cyclodextrins and γ-cyclodextrins as selectors.In order to improve these separation systems different kinds of chargedamphiphiles were introduced in the background electrolyte (BGE).

  5. 13. Development of Methods for Protein and Peptide Analysis Applied in Neuroscience Utilizing Mass Spectrometry

    Author : Johan Pierson; Per Andrén; Ulf Bondesson; György Marko-Varga; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Analytical chemistry; Mass spectrometry; Parkinson’s disease; Metabolism; Profiling Mass Spectrometry; Proteomics; Analytisk kemi; Analytical chemistry; Analytisk kemi;

    Abstract : This thesis describes the utilization of the matrix-assisted laser desorption ionization mass spectrometry (MALDI MS) and electrospray ionization (ESI) MS techniques for analysis of complex brain tissue samples. Direct molecular profiling of biological samples using MALDI MS is a powerful tool for identifying phenotypic markers. READ MORE

  6. 14. Palladium(II)-Catalyzed Addition Reactions : Synthesis of Aryl Amidines and Aryl Ketones

  7. 15. C1 Building Blocks: New Approaches for Thiomethylations and Esterification

    Author : Marcus Söderström; Luke R. Odell; Anders Karlén; Vittorio Pace; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Borontrifluoride; Dimethylsulfide; Thiomethylation; Methylthioethers; Dithioacetalation; Methyl-Dithioacetals; Friedel-Crafts; Diarylmethanes; Defluorination; Methyl-Dithioesters; Thioamides; Diazomethane; Esterification; Medicinal Chemistry; Läkemedelskemi; Medicinal Chemistry; Läkemedelskemi;

    Abstract : The thioether motif is found in numerous pharmaceuticals. The simplest form of this motif, the methyl-thioether is similarly found in many biologically active compounds and has exhibited many advantageous properties. The installation of the thiomethyl moiety can be troublesome due to the toxicity and malodor of small sulfur reagents. READ MORE
