I joined the Orpailleur team at the LORIA in March 2010 as a Post-Doc with a Marie Curie Intra-European Fellowship for Career Development (IEF) from the European Comission CORDIS FP7.

I joined Harmonic Pharma SAS from July 2012 to July 2015.


Projects

Development of Virtual Screening Algorithms: Exploring Multiple Ligand Binding Modes Using Spherical Harmonic Consensus Clustering

My Marie Curie IEF fellowship focused on developing novel spherical harmonic-based consensus clustering algorithms. The GES (Gaussian Ensemble Screening) polypharmacology approach developed in this project is quite generic and it can be broadly applicable to all kind of targets. The approach has been tested and validated using 40 well-known drug targets from the DUD dataset and ligands belonging to 633 annotations (a group of ligands that share an
annotation define a set of functionally related molecules) present in MDDR (MDL Drug Data Report) database. It can be used to screen other libraries to help finding novel polypharmacology relationships between ligand sets. This project provides a generic tool to help deal with cases where multiple ligands may be associated with multiple pocket sub-sites or which may bind multiple targets

GES (Gaussian Ensemble Screening) Approach

Polypharmacology describes the binding of a ligand to multiple protein targets (a promiscuous ligand) or multiple diverse ligands binding to a given target (a promiscuous target). Pharmaceutical companies are discovering increasing numbers of both promiscuous drugs and drug targets. Hence, polypharmacology is now recognised as an important aspect of drug design. The Gaussian Ensemble Screening (GES) is a new and fast way to predict polypharmacological relationships between drug classes quantitatively. This approach represents a cluster of molecules with similar molecular properties as a Gaussian distribution with respect to a selected centre molecule. The similarity score between two clusters of ligands, or “ligand sets”, is calculated from the overlap of their Gaussian distribution functions, and this is then transformed into a probability score, or “p-value”. A large Gaussian overlap between two ligand sets indicates a high probability that these drug classes might be related, whereas a small Gaussian overlap between ligand sets indicates that those drug classes are very unlikely to be related.


GESSE: Predicting Drug Side Effects From Drug-Target Relationships

The in silico prediction of unwanted side effects (SEs) caused by the promiscuous behavior of drugs and their targets is highly relevant to the pharmaceutical industry. Considerable effort is now being put into the computational and experimental screening of several suspected off-target proteins in the hope that SEs might be identified early, before the cost associated with developing a drug candidate rises steeply. Following this need, we present a new method called GESSE to predict potential SEs of drugs from their physico-chemical properties (3D shape plus chemistry) and to target protein data extracted from predicted drug-target relationships. The GESSE approach uses a canonical correlation analysis of the full drug-target and drug-SE matrices, and it then calculates a probability that each drug in the resulting drug-target matrix will have a given SE using a Bayesian discriminant analysis (DA) technique. The performance of GESSE is quantified using retrospective (external database) analysis and literature examples, using area under the ROC curve (AUC), “top hit rates”, misclassification rates, and a Chi-square independence test. Overall, the robust and very promising retrospective statistics obtained and the many SE predictions that have experimental corroboration demonstrate that GESSE can successfully predict potential drug-SE profiles of candidate drug compounds from their predicted drug-target relationships.
