Description

The Interdisciplinary Macromolecular Modeling Platform located into the LCBPT (Laboratoire de Chimie et Biochimie Pharmacologiques et Toxicologiques) offers its expertise to answer structural and functional questions on molecules or complexes of biological interest.

Activities range from visualization of experimental three-dimensional structures and their mutants, to more complex questions such as protein 3D model generation, ligand/receptor interaction (docking, molecular dynamics, simulations), structure / activity studies, virtual screening. The board is open to a collaborative type search.

Recent in silico screening applications:

Over the last 5 years, at least 15 in silico screening (mainly from our in-house library) has been performed mainly to identify new small molecules able to modulate original biological target activity implicated in several therapeutic areas including infections, cancers, mood diseases. Among the most interesting hits, we have notably identified 2 original hits targeting the RED-SMU1 complex with antiviral activity and led to medicinal chemistry “hit to lead” program (collaboration Institut Pasteur, the Institut de Biologie Structurale at Grenoble, the Laboratoire de Chimie et Biochimie Pharmacologiques et Toxicologiques at Univ Paris-Descartes, and the PRABI at Univ Claude-Bernard).

Structure/activity studies:

The last aspect of our work remains the optimization of chemical hit. By working in closed collaboration with chemists and biologists, we performed docking experiments and proposed various modifications to increase compounds potency and selectivity.

Structural aspects:

Using molecular modeling approaches, we have deciphered the binding mode of substrates such as lipid IIby the peptidoglycan amidotransferase MurT/GatD complex from Streptococcus pneumoniae in closedcollaboration with structural expert (Institut de Biologie Structurale at Grenoble).

Another part of our program consist in the identification of putative substrate of characterized protein such as CYP450 and the impact of various mutation. To reach this goal we used both virtual mutagenesis and natural databank compound screening.
