Describing and understanding supramolecular interactions in large biological or bio-mimetic systems has become a major stake over the recent years. However, despite the considerable progress that have been achieved in this field, probing at an atomic scale protein-protein, protein-nucleic acid, protein-lipid, protein-carbohydrate interactions, or the interactions with small molecules, enzyme substrates and regulators, still constitutes a critical challenge for chemists and biochemists.

We are carrying out several collaborations with the groups of Dr. Olivier Maury (Ecole Normale Supérieure de Lyon), Pr. Elise Dumont (Université Côte d’Azur, Nice) and Dr. Christelle Hureau (Laboratoire de Chimie de Coordination, Toulouse) to understand the supramolecular properties of molecules that can be used as crystallization agents of proteins, as modulators of the aggregation process of amyloid peptides, or as non-covalent paramagnetic tags to probe the structure of proteins and peptides by NMR, both in solution and in the solid state. We notably develop an original approach combining paramagnetic NMR and molecular dynamics to probe the dynamic interaction processes between biomolecules and lanthanide complexes. [1] We have recently shown that this hybrid approach makes it possible to capture the detail of these interactions on time scales which are complementary, and to propose a global vision of the dynamic process which reconciles the points of view of the two techniques.

We provide medical researchers with a better understanding, based on metabolomics by NMR, of the complex interplay between the different factors that contribute to the development of diseases. Recent progress in metabolomics has improved our understanding of the system-levels effect of metabolites in biofluids, cells and tissues, using either Mass Spectrometry and/or NMR as complementary detection techniques.
NMR is a highly versatile tool for obtaining metabolic profiles. It allows for analysing all the small metabolites simultaneously, with a high reproducibility. This technique is also non-destructive, robust and quantitative.
Over the last decade, we have developed an expertise in deciphering the complex metabolic pathways that are involved in the evolution of diseases at every step of biological and medical research projects, from preliminary in vitro studies to clinical trials. [1]
Our goal is notably to bring another vision that is complementary to transcriptomics or genomics and can contribute to establish pertinent biomarkers that will help to develop new diagnosis and prognosis approaches. We can help medical researchers to better understand the mechanism of action of new therapeutic approaches, by exploring how the metabolism is correlated to the response of patients to a given treatment. In this context, our group is also developing new analytical tools for boosting resolution and sensitivity of NMR analyses and thus paving the way for new therapeutic options. [2]

Our research activity on hyperpolarization, using dissolution dynamic nuclear polarization (D-DNP), is in line with the study of biological samples, which is a strong theme in our team. By exploiting the high signal enhancements of several orders of magnitude allowed by DNP, we seek to push the limits in terms of temporal resolution for the study of cellular processes in real time, but also to analyse complex biological samples containing low concentrations of metabolites. The starting point of our studies is the cellular metabolism of glutamine and its deregulation in the presence of certain pathologies such as cancer or cardiovascular dysfunction. [1] Initially focused on the study of enzymatic reactions in vitro and on cell extracts, our experiments aim at working in real time on living cells or during ex vivo MRI experiments, as well as on biological samples such as blood, urine or serum, while developing synergies with other thematics and methodological developments of the team, such as high-resolution detection sequences.
