Research


The overall research goal of the Brenk group is to improve methods used for structure-based drug design and to apply these methods to design inhibitors for enzymes with biological relevance. A key point in our research is the interplay of theoretical and experimental methods.

Currently, we are working on the following topics:

1. Navigating chemical space. Several million unique compounds are available for screening from commercial suppliers. Screening all of these compounds, virtually or experimentally, is not feasible. Therefore, methods are needed to efficiently navigate chemical space in order to derive focused libraries or representative subsets.

2. Analysis of protein binding sites. Hit discovery programs are expensive. Accordingly, it would be valuable to know how high the chance of finding a selective, drug-like inhibitor for a given target is before starting the campaign. We are developing methods that can assist in this assesment.

3. Structure-based inhibitor design. In collaboration with other labs we are working on the structure-based design of inhibitors for a variety of targets.

4. RNA-ligand docking. We are developing methods to predict the binding modes and affinities of RNA-ligand complexes. Further, we are exploiting these methods to discover ligands for riboswitches which are novel targets for antibiotics.
