    Sammanfattning : This thesis investigates the anti-leukemic activity of terpenoids isolated from medicinal mushrooms and marine sponges, as well as their possible targets and mechanisms of action.In the first section, we focused on studying the triterpenoidal components of three triterpenoid-enriched medicinal mushrooms Antrodia cinnamomea, Ganoderma lucidum, and Poria cocos, which have been used in folk medicine for centuries and also developed into several contemporary marketed products.

  3. 2. ChemGPS-NP and the Exploration of Biologically Relevant Chemical Space

    Författare :Josefin Rosén; Anders Backlund; Johan Gottfries; Robert Verpoorte; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pharmacognosy; Farmakognosi; Pharmacognosy; farmakognosi;

    Sammanfattning : Chemical space is basically infinite, and comprises all molecules that could possibly exist. Intelligent ways to efficiently navigate through chemical space and to select promising compounds in drug discovery are important tasks, and the focus of this thesis. In this work a new model for chemical space navigation, ChemGPS-NP, was developed. LÄS MER

  4. 3. Studies of Cytotoxic Compounds of Natural Origin and their Mechanisms of Action

    Författare :Jenny Felth; Lars Bohlin; Joachim Gullbo; Ulf Göransson; Thomas Efferth; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; cytotoxic; cardiac glycoside; gambogic acid; cancer; mechanism of action; Pharmacognosy; Farmakognosi; Pharmacognosy; Farmakognosi;

    Sammanfattning : Cancer incidence is increasing and novel anticancer drugs with new mechanisms of action are essential for future chemotherapeutic treatment. Natural products have historically played an important role in the development of anti-cancer drugs and have potential to do so also in the future. LÄS MER

  5. 4. Exploring evolutionary and chemical space using chemoinformatic tools and traditional methods in pharmacognosy

    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; angiosperm chemistry; physicochemical properties of plant specialized metabolites; chemical diversity; chemical space; sesquiterpene lactones; scaffold diversity; molecular framework; cluster analysis; ECFP6; Lindera benzoin; sesquiterpenes; anti-inflammatory; Farmakognosi; Pharmacognosy;

    Sammanfattning : The number of new drugs coming to the market is declining while interest in lead discovery from natural resources is seeing a revival. Although methods for isolation and identification of natural products have advanced tremendously, methods for selection of potential leads have fallen behind. LÄS MER
