From Crystal Structures and Their Analysis to the in silico Prediction of Toxic Phenomena ( The contributions of the honoree to this concept are manifold. A thorough analysis of small-molecule crystal sructures has lead to the development of a directional force field for optimizing ligand-receptor complexes. The understanding of phenomena such as induced fit or dynamic binding have been pioneered by Professor Dunitz's analyses of dynamic properties extracted from crystal statics'. His more-recent contributions to the understanding of solvation effects and entropic contributions to ligand binding are still teaching us important lessons on how to model small-molecule—protein complexes.)
