Drug Design and Optimization
In order to combat the increasing number of resistant pathogens, the development of new anti-infective drugs is an important goal for pharmaceutical research. Efficient medications with novel modes-of-action to fight infectious diseases are urgently needed. Below, you may read more about the design, identification and optimisation of new drug candidates. This group is located at the Helmholtz Institute for Pharmaceutical Research Saarland (HIPS).
