attributable to an increased opening of potassium channels. The resulting quantitative in vitro data has been used to analyze the structure-activity relationships for potassium channel opening, allowing the biological activity to be rationalized in terms of a pharmacophore involving a hydrogen-bond-acceptor element, a hydrogen-bond-donor element, and a lipophilic binding group. A model for the binding of pinacidil-related
