In the development of new potential drugs the risk estimate of health hazards is a main challenge. To face this challenge, the careful and extensive investigation of known toxins is the basis to assess the properties of unknown substances. In order to achieve this aim, the Structural Bioinformatics Group Institute of Molecular Biology and Bioinformatics, Charité (Cbf), Berlin, Germany has collected toxic compounds from literature and web sources in the database SuperToxic.
