The "Bioactive Molecules" team, thanks to the different groups constituting it, focuses on the synthesis of molecules with antiviral or antitumor properties, as well as biological tools (inhibitors, fluorescent probes, diagnostic tests, etc.) needed to the study of their activity in vitro. The team is also developing new methods of immunoassays for the pharmacological study of drugs used in antiviral therapy, and multifunctional nanocarriers used in particular to improve the transfer of genes (gene therapy) and / or cell therapy.

The team (CNRS Website) is working especially on oriented thematic such as design and implementation of nucleosides analogues and oligonucleotides as therapeutic and biological tools. An important activity is the development of tools to study nucleic acid / protein interactions. Our approach is interdisciplinary: the chemistry of biological processes is studied by physical methods (spectroscopy) based on the skills of organic chemistry and biochemistry present in the team. One of the major challenges of the post-genomic era and proteomics concerns the characterization and quantification of protein / nucleic acid interactions. In addition to the fundamental aspects of these studies, they also aim to understand the molecular basis of various diseases and to develop diagnostic methods and high throughput screening. To achieve these goals, we must nevertheless have nucleobases sensitive to environmental changes that disrupt as low as possible interfere with the structure and function of these nucleic acids. In this context we explored to access of new tools based on different approaches to label nucleic acids and in particular in the development of new fluorescent probes.

Our projects

Nucleic acids and the development of new tools are the main objectives of our research activities. We introduced a new concept based on the fluorescent probes properties to emit at two different wavelengths for an internal and external labeling of nucleic acids. These tools are able to translate with high sensitivity nucleic acid / protein interactions. This project was supported by an 'ANR Blanche' (2007-2011). It is part of a collaboration with Pr. Yves Mely ( , - Faculty of Pharmacy, Strasbourg) for the photophysical studies and interaction with proteins, Pr. Alexander Demchenko (Palladin Institute of Biochemistry, Kiev) and Professor Vasyl Pivovarenko ( - Kiev National Taras Shevchenko, chemistry Faculty) for their expertise in the chemistry of fluorescence probes, and Dr. Cyril Kenfack ( - University of Douala) for his contributions to modeling studies and ab initio calculations.

Our expertise in this field has enabled us to propose these photophysical tools to study different biological processes involving nucleic acid / protein interactions.

One of our projects is the study of the DNA methylation mechanism which is still unclear. A better understanding of this mechanism at the molecular level is a major issue both from a fundamental point of view for Life Sciences and Medicine for the pharmaceutical industry. This research is supported by the FRM (2012-2015) and ANR (2012-2015). This project is developed in partnership with the team of Pr. Yves Mely ( , - Faculty of Pharmacy, Strasbourg).

    

Another project was initiated in collaboration with Pr. Olga Fedorova ( - Novosibirsk State University) who is interested in studying DNA repair mechanisms (Nobel Prize in chemistry 2015). A better understanding of these mechanisms is an important issue for the Life Sciences and human health. This project is supported by the PACA region through an exploratory project (2014-2015).
