WebIn both cases a dual- topology approach was used. Additionally, molecules from a small scaffold hopping dataset published by Wang et al. 12 were used to assess the feasibilty of more advanced structural changes (Figure 2). Results for scaffold hopping WebR-FEP-R Calculations. Dual Topology and Restraints. In the R-FEP-R method,22 the system is divided into three sets: (1) dual-RV set, which represents one conformation of the residue/fragment of interest that changes from real to virtual (i.e., dummy) during the FEP simulations, (2) dual-VR set, which represents the other conformation that ...

WebFEP-R method was developed based on the idea of the dual topology free energy perturbation (FEP) transformation in relative binding free energy calculations.4 The dual topology free energy perturbation method is widely applied to estimate the binding free energy difference between two ligands that are similar in structure.4,30,31 The

WebAs of GROMACS version 4.0, topology modifications for simple (de)couplings are no longer required (hooray!), but in the case of mutating one molecule to another, wherein bonded and nonbonded terms may change, the old-style modifications (the so-called "dual topology approach") would still be required. WebFree energy perturbation (FEP) calculations are now routinely used in drug discovery to estimate the relative FEB (RFEB) of small molecules to a biomolecular target of interest. Using enhanced sampling can improve the correlation between predictions and experimental data, especially in systems with conformational changes. Due to the large number of …
