The µ opioid receptor (µOR), the principal target to control pain, belongs to the G protein-coupled receptors (GPCRs) family, one of the most highlighted protein families due to their importance as therapeutic targets. The conformational flexibility of GPCRs is one of their essential characteristics as they take part in ligand recognition and subsequent(More)
The search of molecular structures inside a large database of chemical compounds is a critical step for many computer programs used in several domains of chemistry. During the last years, the size of many chemical databases has dramatically increased, hence in the meantime, search engines needed to be more and more powerful. The speed and the efficiency of(More)
The interaction energy and the structure of water molecules either inside the Gramicidin A transmembrane channel or at its two extremities is examined with the use of iso-energy maps and Monte Carlo simulations. The shape of the channel as experienced by water is analyzed in detail. Variations in the hydration structure due to the presence of a Na+ ion(More)
The purpose of this study was to explore the use of detailed biological data in combination with a statistical learning method for predicting the CYP1A2 and CYP2D6 inhibition. Data were extracted from the Aureus-Pharma highly structured databases which contain precise measures and detailed experimental protocol concerning the inhibition of the two(More)
A reduced point charge model was developed in a previous work from the study of extrema in smoothed charge density distribution functions generated from the Amber99 molecular electrostatic potential. In the present work, such a point charge distribution is coupled with the Amber99 force field and implemented in the program TINKER to allow molecular dynamics(More)
Thermodynamic and kinetic aspects of excited state intramolecular proton transfer (ESIPT) are investigated in 11 chromophores harboring an intramolecular N-H∙∙∙N hydrogen bond [pyridyl pyrazole, pyridyl pyrrole, azaindole, pyridyl indole, pyrroloquinoline, and an analogue of the Blue Fluorescent Protein (BFP) chromophore] with the help of quantum mechanical(More)
The [3]rotaxane synthesised as a single isomer constituted of two cyclodextrins (CDs) and an azobenzene chain [M.R. Craig, T.D.W. Claridge, M.G. Hutchings, H.L. Anderson, Synthesis of a cyclodextrin azo dye [3]rotaxane as a single isomer, Chem. Commun. 16 (1999) 1537-1538] has been investigated using molecular mechanics (MM) and dynamics (MD) with the MM3(More)
Experimental and theoretical physico-chemical methods were used to investigate the interaction between aryl-oxazolidinones and monoamine oxidase (MAO). Several arguments suggest that these compounds interact with the flavin adenine dinucleotide (FAD) cofactor of MAO. The calculation using ab initio molecular orbital methods of the electronic properties of(More)
The evaluation of the ADME (absorption, distribution, metabolism, and excretion) properties of drug candidates is an important stage in drug discovery. To speed up the numerous tests carried out on large databases of compounds, the help of robust and accurate in silico filters is increasingly required. We propose here a method to build predictive and(More)
