The present thesis describes the successful establishment of a novel NMR-based tool to detect natural inhibitors of the pharmaceutically addressed 20S proteasome in crude culture broths of microorganisms or raw extracts from plants and fungi. It was applied for the analysis of an insect pathogenic bacterium, which led to the isolation of an extremely powerful secondary metabolite. The methodology can be utilized for future natural product research in this field, which may result in the discovery of many more promising compounds.
