The main teaching responsibilities of the professorship are (1) in the education of pharmacy students in pharmaceutical biology; and (2) the education of medical students in basic general and organic chemistry. The teaching in pharmaceutical biology covers basic aspects of the structure and biosynthesis of plant constituents and the pharmacological effects and therapeutic applications of biogenic drugs of plant origin (extract-based herbal medicines; isolated natural products). At the practical level it includes the microscopic analysis of plant material (pharmacopoeia), the chromatographic analysis of medicinal plants, extraction methods, qualitative/quantitative determination of medicinal plant constituents, and the isolation of natural products. The teaching for medical students addresses the most important fundamental concepts in chemistry (atomic structure, chemical bonds, thermodynamics and kinetics of chemical reactions, acid-base equilibria, types and reactivity of organic compounds, stereochemistry, biomolecules) and highlights connections between chemical processes and medically important biochemical, physiological, and pharmacological questions. In addition, we are also involved in Master level courses on medicinal chemistry and drug discovery. For more information please consult the course catalog of the ETH Zürich.
