  2. 1. Natural Products from Cameroonian Medicinal Plants

    Author : Apollinaire Tsopmo; Centrum för analys och syntes; []
    Keywords : 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;

    Abstract : 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.

  4. 2. Synthesis Towards Biologically Active Natural Products

    Author : Rikard Larsson; Centrum för analys och syntes; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Transtaganolide; basiliolide; natural product; total synthesis; biomimetic; Thapsia; Diels-Alder; Ireland-Claisen; Pictet-Spengler; tetrahydroisoquinoline; indole;

    Abstract : In 2005 two research groups independently reported the isolation of a series of structurally intriguing C-19 terpenolides from the plants Thapsia transtagana and Thapsia garganica. The compounds were shown to be potent inhibitors of the sarco/endoplasmic reticulum Ca2+-ATPases. READ MORE
