    Sammanfattning : This thesis describes the synthetic preparation of somecompounds, which can serve as chemical signals for use in thedevelopment of control methods for pest insects. The compoundssynthesised are of the isoprenoid type and of two kinds:carvone derivatives and germacranes. LÄS MER

  4. 3. Biologically Interesting Compounds from Natural Sources

    Författare :Veronica de la Parra; Centrum för analys och syntes; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; cytotoxicity; Natural products; terpenoids; vasorelaxant activity; allylmercaptane; diabetes mellitus type II; Organisk kemi; Organic chemistry; Cacalia decomposita; GPR40 receptor; TRP channel;

    Sammanfattning : Natural products have traditionally played a major role in the drug discovery process. Besides constituting extremely popular drugs in the market, and an ever-increasing source of interesting and novel chemical structures, they have also aided the characterization of many a pharmacological target.

  5. 4. Natural Products from Cameroonian Medicinal Plants

    Författare :Apollinaire Tsopmo; Centrum för analys och syntes; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Växtbiokemi; Plant biochemistry; antiplasmodial.; antitrypanosomal; diarylheptanoids; terpenoids; flavonoids; aframodial; Aframomum; Reneilmia cincinnata; Dorstenia; Euphorbia; Lepidobotrys staudtii; Pentadiplandra brazzeanea; Vernonia guineensis; Natural products; Myrica arborea;

    Sammanfattning : Natural product chemistry is a main research area in Cameroon, as well as for the division of Bioorganic Chemistry at Lund Institute of Technology. A review of the results obtained recently with Cameroonian medicinal plants shows that a large number of compounds, many with complex structures, have been isolated and characterised, and the work presented in this thesis is part of this effort.

  7. 5. Biologically active terpenoids from Bolivian medicinal plants

    Författare :Maribel Lozano Palacios; Centrum för analys och syntes; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Bolivian plants; cytotoxicity; triterpenes; damsin; breast cancer;

    Sammanfattning : Pseudo-guaianolides represent a large group of sesquiterpene lactones exhibiting significant cytotoxic and anti-inflammatory activities. Their biological activities are due to a 훼-methylene-훾-lactone unit in their chemical structure, which reacts with free sulfhydryl groups of free cysteine via a Michael-addition. LÄS MER
