We present a new computational strategy for calculating the absolute binding free energy for protein ligand association in the context of atomistic simulation in explicit solvent. The method is based on an appropriate definition of a solute tempering scheme enforced via Hamilton replica exchange method (HREM). The definition of "solute" includes both the(More)
Understanding binding mechanisms between enzymes and potential inhibitors and quantifying protein-ligand affinities in terms of binding free energy is of primary importance in drug design studies. In this respect, several approaches based on molecular dynamics simulations, often combined with docking techniques, have been exploited to investigate the(More)
When developing hard real-time applications, one of the crucial aims of the designer@) is to ensure a predictable time behaviour in all anticipated conditions. In particular, it would be highly desirable to verify the compliance of the application with its timing requirements in the early steps of the development, especially at the design stage: an early(More)
The conformational landscape of three FK506-related drugs with disparate inhibition constants is determined in bulk solution using a replica exchange simulation method with solute torsional tempering. Energetic fitness of important drug conformations with respect to the FKBP12 protein is evaluated by molecular mechanics. Results show that the experimental(More)
Due to its central role in immunosuppression and cell proliferation and due to its specific peptidyl-prolyl-isomerase (PPI) function, the FKBP protein family is at the crossroad of several important metabolic pathways. Members of this family, and notably FK506 binding protein (FKBP12), are thought to be involved in neurodegenerative diseases such as(More)
