Efforts to improve the potency and physical properties of the aminopyridiopyrazinone class of PDE5 inhibitors through modi. cation of the core ring system are described. Five new ring systems are evaluated and features that impart improved potency and improved solubility are delineated. (C) 2009 Elsevier Ltd. All rights reserved.
