Phytochemistry & Biodiscovery

The enormous structural diversity of secondary metabolites from plants, fungi, microorganisms, and marine sources provides an indispensable resource for new bioactive substances and lead structures from numerous classes of compounds. In the process of early drug discovery guided by rationalized approaches natural products are investigated for their bioactivity (e.g. on cellular systems, see “Molecular Targets” group, or by our phenotypic screening platform using Caenorhabditis elegans; foto). Our research mainly focuses on the identification of novel drug leads against communicable and non-communicable diseases.
