  1. 1. BIOACTIVE ORGANOMETALLIC COMPOUNDS

    Författare :Haris Bjelosevic; Centrum för analys och syntes; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; biological; kinetic; gold; platinum; bioactive; phosphine; ruthenocene; Ferrocene;

    Sammanfattning : Various metal complexes have been used in medicine traditionally, although their use was often connected with mystery and with a lack of empirically (clinically) proven effect. In modern times, the development of biochemistry, bioinorganic and bioorganometallic chemistry allows us more in-depth understanding of biological action of metal containing substances. LÄS MER

  3. 2. Novel biologically active compounds by semisynthesis with fungal metabolites

    Författare :Johan Eriksson Bajtner; Centrum för analys och syntes; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Organisk kemi; Organic chemistry; bioactive compounds.; isovelleral; podoscyphic acid; Natural products; semisynthesis;

    Sammanfattning : Natural products have been shown to be an important source of novel compounds for the development of new drugs and pesticides. However, many biologically active natural products contain reactive functionalities that make them toxic. LÄS MER

  4. 3. Biochemical Interactions of Some Saproxylic Fungi

    Författare :Joel Ljunggren; Bengt Gunnar Jonsson; Erik Hedenström; Dan Bylund; Mittuniversitetet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; biologically active compounds; bioactive; fungi-fungi interaction; fungi co-culture; extracellular amino acids.;

    Sammanfattning : Interactions are all around us, and as humans we may use words and gestures to communicate our intentions. At the micro level of fungi, communications are replaced by chemical signals and structure. LÄS MER

  5. 4. Bioactive Compounds from the Marine Sponge Geodia barretti : Characterization, Antifouling Activity and Molecular Targets

    Författare :Martin Sjögren; Lars Bohlin; Per Jonsson; Anna-Karin Borg-Karlsson; Uppsala universitet; []
    Nyckelord :Pharmacognosy; Geodia barretti; barettin; secondary metabolites; settling inhibition; Balanus improvisus; analogs; 5-HT; Farmakognosi;

    Sammanfattning : The marine sponge Geodia barretti produces a range of secondary metabolites. Two of these compounds were isolated and elucidated guided by their ability to inhibit settlement of cypris larvae of the barnacle Balanus improvisus. LÄS MER
