Ensemble-Based Steered Molecular Dynamics Predicts Relative Residence Time of A2A Receptor Binders A. Potterton, F. Husseini, M. Southey, M. Bodkin, A. Heifetz, P. V. Coveney, A. Townsend-Nicholson, Journal of Chemical Theory and Computation, 15 (5), 3316–3330 2019, 10.1021/acs.jctc.8b01270 We present a novel computational method for the reliable prediction of relative drug-target residence time. From ensemble-based steered molecular dynamics simulations, the change in energy between the ligand and water during dissociation (∆ELW) is obtained. These calculated ∆ELW values correlate strongly to the associated experimental residence times of 17 Adenosine A2A receptor ligands, a prototypical class A GPCR.
