  2. 21. Design, Synthesis and Evaluation of Catalytic Chalcogenide Antioxidants

    Author : David Shanks; Lars Engman; John C Walton; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Organic chemistry; antioxidant; tellurium; selenium; computational design; homolytic substitution; radical cyclisation; microwave-assisted synthesis; antioxidant regeneration; Organisk kemi; Organic chemistry; Organisk kemi;

    Abstract : This thesis describes the design, synthesis and evaluation of novel chalcogenide antioxidants.A computational model for the prediction of antioxidant properties of chalcogen-containing antioxidants has been developed. READ MORE

  4. 22. Design and Synthesis of Novel HIV-1 Protease Inhibitors Comprising a Tertiary Alcohol in the Transition-State Mimic

    Author : Jenny Ekegren; Anders Hallberg; Daniel Rich; Uppsala universitet; []
    Keywords : Chemistry; HIV AIDS; HIV-1 protease inhibitor; transition-state mimic; tertiary alcohol; palladium; cross-coupling; aminocarbonylation; microwave; molybdenum hexacarbonyl; Kemi;

    Abstract : HIV-1 protease inhibitors are important in the most frequently used regimen for the treatment of HIV/AIDS, the highly active antiretroviral therapy (HAART). For patients with access to this treatment, an HIV infection is no longer lethal, but rather a manageable, chronic infection. READ MORE

  5. 23. Development of New Methodology in Organic Synthesis: Lewis Acid-Mediated Rearrangements of Ammonium Ylides and Addition of 1, 3-bis(silyl) propenes to Aldehydes

    Author : Pavel Tuzina; Peter Somfai; Ari Koskinen; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; asymmetric; amino acid; ammonium ylide; Lewis acid; microwave irradiation; Organic synthesis; Organisk syntes;

    Abstract : This thesis deals with the development of new methodologies in organicsynthesis. The main focus is on the development of Lewis acid-mediated [1,2]-rearrangements of ammonium ylides and the novel addition of 1,3-bis(silyl)propenes to carbonyl compounds. READ MORE

  6. 24. Synthesis, Characterisation and Application of 68Ga-labelled Macromolecules

    Author : Irina Velikyan; Bengt Långström; Mats Bergström; Helmut Maecke; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Chemistry; 68Ga; 68Ge 68Ga generator; radiolabelling; microwave heating; specific radioactivity; peptide; protein; antibody; oligonucleotide; positron emission tomography; tumour; Kemi; Chemistry; Kemi;

    Abstract : The positron emitting radionuclide 68Ga (T1/2 = 68 min) might become of practical interest for clinical positron emission tomography (PET). The metallic cation, 68Ga(III), is suitable for complexation with chelators, either naked or conjugated with biological macromolecules. READ MORE

  7. 25. Scheduling and Communication Synthesis for Distributed Real-Time Systems

    Author : Paul Pop; Petru Eles; Zebo Peng; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; distributed embedded systems; hard real-time systems; time-triggered protocol; scheduling; schedulability analysis; communication synthesis; control dependencies; Computer science; Datavetenskap;

    Abstract : Embedded systems are now omnipresent: from cellular phones to pagers, from microwave ovens to PDAs, almost all the devices we use are controlled by embedded systems. Many embedded systems have to fulfill strict requirements in terms of performance and cost efficiency. READ MORE
