Course introduction
The purpose of the course is to provide the participants with fundamental knowledge of natural product chemistry including the distribution and biosynthesis of natural products and their function within biological systems, as well as knowledge of drugs, drug extracts and bioactive natural products from plants and fungi that are used for production of medicine and herbal remedies.

Expected learning outcome
After ending the course the students are expected to be able to:
• Classify natural products based on their chemical structure and indicate their possible biosynthesis.
• Estimate the characteristics of natural products and their structure/activity relationships as well as their possible effect and mode of actions in biological systems, including humans/animals.
• Estimate the effect of well-known herbal remedies and drugs based on their content of potential bioactive compounds.
• Explain the difference between herbalmedicinal products, traditional herbal medicinal products, and food supplements.
• Explain the general principles on how to isolate and characterise bioactive natural products from plants and fungi.
• Describe the content of research papers within the subjects and be critical towards the content and conclusions draw.
• Describe the subject in writing and orally.

Subject overview
1. Biosynthesis of secondary metabolites: The acetate/polyketide pathway, the mevalonate and deoxyxylulose phosphate pathway, the shikimate pathway and the biosynthesis of alkaloids.
2. Distribution of secondary metabolites in plants, including chemotaxonomy.
3. Biological activity of secondary metabolites their effect, mode of action and function in biological systems, including secondary metabolites isolated from medicinal plants/fungi and used as drugs, model compounds for the development of new drugs or as start materials for semi-synthetic drugs.
4. Methods for the isolation of bioactive natural products by for example assay- and bioassay-guided chromatographic fractionation.
