  2. 2. Approaches to soft drug analogues of dihydrofolate reductase inhibitors Design and synthesis

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Malin Graffner Nordberg; Uppsala universitet.; [2001]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pharmaceutical chemistry; soft drug; dihydrofolate reductase; synthesis; Farmaceutisk kemi; PHARMACY Pharmaceutical chemistry; FARMACI Farmaceutisk kemi; Organic Pharmaceutical Chemistry; Organisk farmaceutisk kemi;

    Sammanfattning : The main objective of the research described in this thesis has been the design and synthesis of inhibitors of the enzyme dihydrofolate reductase (DHFR) intended for local administration and devoid of systemic side-effects. The blocking of the enzymatic activity of DHFR is a key element in the treatment of many diseases, including cancer, bacterial and protozoal infections, and also opportunistic infections associated with AIDS (Pneumocystis carinii pneumonia, PCP).

  3. 3. Absolute Asymmetric Synthesis

    Detta är en avhandling från Göteborg : Chalmers University of Technology

    Författare :Anders Lennartson; Göteborgs universitet.; Gothenburg University.; [2009]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; absolute asymmetric synthesis; enantioselective synthesis; chirality; optical resolution; spontaneous resolution; conglomerate; organozinc reagents; organometallic chemistry; coordination chemistry; supramolecular chemistry; intermolecular interactions;

    Sammanfattning : Absolute asymmetric synthesis is the synthesis of optically active products from achiral or racemic precursors only. This has generally been regarded as impossible and is relevant in the discussion of the origins of biomolecular homochirality. LÄS MER

  4. 4. Parabolic Synthesis

    Detta är en avhandling från Lund : Lund University

    Författare :Erik Hertz; [2011]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Many consumer products, such as within the computer areas, computer graphics, digital signal processing, communication systems, robotics, navigation, astrophysics, fluid physics, etc. are searching for high computational performance as a consequence of increasingly more advanced algorithms in these applications.
