  1. 31. Applications of multi-component condensations and development of polyamine synthesis on solid-phase

    Författare :Daniel Jönsson; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Neurochemistry and Neurotoxicology; neurokemi och neurotoxikologi;

    Sammanfattning : Solid-phase synthesis of small non-polymeric molecules has become increasingly important as a tool in the development of pharmacologically active compounds. Of particular interest are the syntheses of compounds with low molecular weight, low polarity and a reduced flexibility of the functional groups, i.e. LÄS MER

  3. 32. Drug discovery against leishmaniasis : Bio- and chemoinformatic guided strategies for target evaluation and hit identification

    Författare :Elisabet Vikeved; UCM Alsmark; Christian Sköld; David Horn; Uppsala universitet; []

    Sammanfattning : Leishmaniasis is a neglected tropical disease mainly affecting poor people in developing countries. It is caused by infections of flagellated protozoa belonging to genus Leishmania. The few available drugs are associated with problems such as low effectiveness, severe side effects and resistance development.

  4. 33. Synthesis of heterocycles from anthranilic acid and its derivatives

    Författare :Per Wiklund; Jan Bergman; Norbert de Kimpe; Södertörns högskola; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Anthranilic acid; synthesis; heterocycles; benzodiazepines; HNO nitrosyl ;

    Sammanfattning : Anthranilic acid (2-aminobenzoic acid, Aa) is the biochemical precursor to the amino acid tryptophan, as well as a catabolic product of tryptophan in animals. It is also integrated into many alkaloids isolated from plants. Aa is produced industrially for production of dyestuffs and pharmaceuticals. LÄS MER

  5. 34. Towards the Rational Design of Molecularly Imprinted Polymers

    Författare :Håkan S Andersson; Ann-Christin Koch-Schmidt; Ian A Nicholls; Klaus Mosbach; Richard F Venn; Tillämpad biokemi; []

    Sammanfattning : Molecular imprinting is a technique by which polymeric materials selective for a given target molecule can be created through a casting procedure. Functionalised monomers are added to a solution of molecular templates. LÄS MER

  7. 35. Quinine metabolism in man : emphasis on the 3-hydroxylation as a biomarker reaction for the activity of CYP3A4

    Författare :Rajaa A Mirghani; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Quinine is one of the cinchona alkaloids and used in the treatment of severe forms of malaria. Formation of 3-hydroxyquinine is catalysed by cytochrome P-450 3A4 (CYP3A4), which is the enzyme involved in the metabolism of about 50% of all drugs in clinical use. LÄS MER
