PRESENTATION

University of Paris Descartes and the Laboratory of Pharmaceutical and Toxicological Chemistry and Biochemistry (LCBPT) are associated to the “Chimiothèque Nationale” (CN) – French National Chemical Library of CNRS since 2004. Our laboratory is located at the chemistry / biology interface with various disciplinary activities. We develop both biologically active molecules for therapeutic purposes but also tools for the characterization of new targets, for the elucidation of biological mechanisms and for imaging. The teams are particularly distinguished in the development of probes and in various spectroscopic techniques such as EPR and NMR for in vitro and in vivo studies. The unit has expertise ranging from synthetic methodology to bioorganic and bioinorganic chemistry. Biological research themes focus mainly on anti-infectives (antibacterials, antivirals), anticancer drugs, the central nervous system, the immune system and toxicology.

Goals

We have established a pool of products of interest, which after verification of their purity, have been integrated into an electronic database common to the whole laboratory in order to valorize these compounds for other applications whether by virtual screening or physical screening. We have established a protocol (screening – identification – analysis and storage) which allows to manage the synthesized products (intermediate and final) of the last 30 years resulting from projects completed or stopped after the departure of the researchers.
We have 3 chemical libraries that are being evaluated in the laboratory and can be the subject of new collaborative screening projects.

Services

With the technical and financial support of the CN and the laboratory, we have collected about 5,500 products from all teams, creating a structural database managed under IsisBase (sdf files). Of these, 4950 compounds are available for automated screening in the form of 96-well plates or sherry picking.

As part of the CN / SANOFI agreement, a copy of our plates is stored at EVOTEC (Toulouse) and available via the French National Chemical Library and ChemBioFrance.

We also have several 96-well plate sets available for internal screenings and collaborations with screening platforms. At the same time, we undertook the virtual screening of our chemical library with the laboratory’s modeling service (Macromolecular Modeling Platform) in the framework of internal and external collaborations.

VALORIZATION

We currently have 15 external collaborations following the screening of our chemical library via the CN, 5 internal and 10 external internal screening studies. The balance sheet is currently 6 publications and 4 ANR filings.
