Density Functional Theory Transition-State Modelling for in silico Toxicity Prediction

Piers Townsend

Research output: Contribution to conferencePoster


Assessing the safety of new chemicals, without introducing the need for animal testing, is a task of great importance. The Ames test, a widely used bioassay to assess mutagenicity, can be an expensive and wasteful process. In silico methods have previously been used for the prediction of Ames test results, however, these
computational methods often neglect the intrinsic chemistry associated with DNA reactivity. This poster presents a fast, low-cost method for predicting Ames test results in 1,4 Michael Acceptors using density functional theory transition-state modelling.
