Développement d'une plateforme de prédiction in silico des propriétés ADME-Tox

Abstract : Absorption, Distribution, Metabolism, Elimination (ADME) and Toxicity (Tox) properties are crucial for the success of clinical trials of a drug candidate. During this process, chemoinformatics is regularly used to predict the ADME-Tox profile of bioactive compounds and to improve their pharmacokinetic properties. In silico approaches have already been developed to improve poor pharmacokinetics and toxicity of lead compounds. These predictive models, based on the quantification of structure-activity relationships (QSAR), were not always efficient enough due to the low number of accessible biological data and their heterogeneity induced by the differences in experimental assays or the significant experimental error. In this thesis, we first built a database containing 150,000 data points for about 50 ADME-Tox properties. In order to valorize all this data, we then proposed an automatic platform for creating predictive models. This platform, called MetaPredict, has been designed to optimize each step of model development, in order to improve their quality and robustness. Third,, we promoted the statistical models using the online application of MetaPredict platform. This application has been developed to facilitate the use of newly built models, to provide a simplified interpretation of the results and to modulate the obtained observations according to the needs of the researchers. Finally, this platform provides an easy access to the ADME-Tox models for the scientific community.
