Drug Discovery Group


Identifying and characterising new drugs and drug-like molecules.

It is widely acknowledged that the current drug discovery pipeline by the major pharmaceutical companies is in crisis. As a consequence, novel approaches around drug discovery are increasingly developed by academia as well as the resulting small spin-off companies outside the restraints of rigid, dogmatic development regimens. We see this global trend as an opportunity and our centre works towards providing novel lead compounds for a variety of indications that are based on novel approaches, unique biological resources and out-of-the-box-thinking.

The drug-discovery group works on the identification and characterisation of new drugs and drug-like molecules with therapeutic activity. These molecules are either synthesized de novo, are isolated from natural sources, are modified versions of known molecules or are based on the re-profiling of known drug molecules. We have the capacity to take a molecule from its first synthesis or isolation, via cell-free and cell-based assays all the way to proof of concept testing in pre-clinical in vivo models of human disorders. At the same time, we also characterize molecular and cellular events triggered by exposure to drugs, which support mode of action studies and illuminate toxic liabilities of individual compounds. To facilitate drug screens for other users, we store a selection of drugs, drug-like compounds and novel molecules in a small library format that can be interrogated in a variety of different assays. In addition, our group constantly develops new assays that are optimized for use in multi-well plates to work towards medium-throughput screening. We aim to use cutting edge drug design to identify new pharmacological entities but more importantly our work is intended to provide patent protected drug candidates for the real world that can attract interest by the pharmaceutical industry.

Specialist Fields and Areas of Investigation

Based on the expertise of the individual team members, we aim to discover novel molecules or re-profile old molecules for a variety of indications incl. cancer, chronic pain, neurodegeneration, psychiatric conditions and mitochondrial disorders. Broad profiling of drugs and drug-like molecules allows not only the rational optimization of drug characteristics for a particular indication; it also provides an opportunity for serendipity findings that can give rise to useful drug derivatives for novel indications.
