    The rates at which molecules associate and dissociate are important determinants of biological function. Growing evidence that the efficacy of a drug can be correlated to target binding kinetics has led to the development of many new methods for computing rate constants for receptor-ligand binding processes [1,2], see also kbbox.h-its.org. These methods aim at overcoming the gap of many orders of magnitude between the times accessible to conventional molecular dynamics simulations and the much slower drug-target binding kinetics. Here, I will describe our recent studies to develop computationally efficient methods to estimate protein-ligand binding kinetic parameters [3-8].
