Chemical and biological data abound – our mission is to make sense of it.
We do so by employing cheminformatics, chemogenomics and related techniques in order to rationalize why a ligand binds to a protein target; why particular chemical features lead to toxicity; and why one compound causes a biological phenotype and another one does not. Given that current bioactivity databases contain millions of molecules; our conviction is that we should learn from the past chemistry that has been made, in order to design better molecules in the future.
One example application is shown below [Young et al.], illustrating how phenotypes (in this case from high-content screening) can be rationalized using the chemical structure of ligands, and predicted targets, based on 600,000+ bioactivity data points available in current databases.
We also work in the area of ligand toxicity prediction – recent examples include the prediction of compounds, which inhibit the hERG channel [Doddareddy et al.], a potassium channel implicated with ‘sudden death syndrome’ caused even by approved drugs. Common to all of our studies is the analysis of chemical structures, with the goal to design better bioactive matter in the future.
