Directions to our laboratory


I obtained my Ph.D. in February 1993 in Organic synthesis (@ the "Laboratoire de Biochimie Structurale", Université d'Orsay-Paris XI, Orléans, France; Prof. J.-M. Beau and Dr. J. Prandi). During my thesis, I studied how asymetric synthesis methods are efficient to synthesize unusual thiosugars, components of enediyne antibiotics. Then, I did two post-docs: During the first one (@ the "Biomembrane Institute", University of Washington, Seattle, WA, USA; Prof. S.-i. Hakomori and Dr T. Toyokuni), I studied the electrophilic azidation as a new source of 2-aminosugars. I also worked on the development of glycopeptide vaccines useful against breast cancer, and on 2D-NMR structural studies of glycopeptides. During the second one (@ the "Laboratoire de Synthèse de Biomolécules", Université d'Orsay-Paris XI, Orsay, France; Prof. J.-M. Beau), I was involved in the development of a new method relevant to reduce complex azido-oligosaccharides, based on Samarium diiodide. In October 1996, I got a position of Assistant Professor or "Maître de Conférences" (@ the UFR de Pharmacie, Université de Picardie Jules Verne, Amiens; Prof. J.-P. Monti, and then Prof. J. Rochette), and I worked on the synthesis and structural studies of proteins and/or oligopeptides. From September 2003 up to September 2005, I worked as "Research Associate" (@ The Scripps Research Institute, Dpt. of Molecular Biology, La Jolla, CA, USA; Prof. D. A. Case). I was involved in the study of electrostatic interactions in proteins and nucleic acids. Since September 2006, I am Professor of Organic chemistry (@ the UFR de Pharmacie, Université de Picardie Jules Verne), and I am interested in bioinformatics as well as empirical force field development, atomic charge derivation and molecular dynamics studies of non-natural oligosaccharides, oligonucleotides and polypeptides.

Curriculum Vitae


Development of empirical force fields and dedicated tools

- RESP ESP charge Derive (presently belongs to the R.E.D.-III tools) derives 'RESP' or 'ESP' atomic charges and generates force field libraries for molecular fragment(s) or whole molecule(s) starting from a set of un-optimized PDB structures. It sequentially executes (i) the GAMESS-US, Firefly or Gaussian program to optimize the structure(s) studied and to compute the corresponding Molecular Electrostatic Potential(s) (MEP), and (ii) the RESP program to fit the atom-centered charges to the MEP previously determined.

- RESP ESP charge DDataBase or R.E.DD.B. is a database that allows freely storing and distributing RESP or ESP charges and force field libraries for new molecules and molecular fragments in the scientific community.

- RESP ESP charge Derive Server or R.E.D.S. is a web server, which executes the R.E.D.-IV program (version beta) to generate RESP and ESP charges and complex force field topology database for new molecules.

- AmberFFC (presently version 1.3) automatically converts the AMBER and GLYCAM force fields in the Accelrys format. AmberFFC is intended to any modeler, who is interested in using the current AMBER and GLYCAM force fields within the Accelrys programs.

- FFParamDev (still unavailable) computes bond, angle and torsion force field parameters. FFParmDev interfaces the GAMESS or Gaussian program to generate quantum mechanics energies (Eqm) and the "Sander" module of the AMBER package to get molecular mechanics energies (Emm). Then, it fits Emm values to Eqm ones, and determines force field parameters.
