Investigation of Aminopyridiopyrazinones as PDE5 Inhibitors: Evaluation of Modifications to the Central Ring System.
Structural highlights
FunctionPDE5A_HUMAN Plays a role in signal transduction by regulating the intracellular concentration of cyclic nucleotides. This phosphodiesterase catalyzes the specific hydrolysis of cGMP to 5'-GMP.PDE4A_HUMAN Hydrolyzes the second messenger cAMP, which is a key regulator of many important physiological processes.[1] [2] Evolutionary Conservation Check, as determined by ConSurfDB. You may read the explanation of the method and the full data available from ConSurf. Publication Abstract from PubMedEfforts to improve the potency and physical properties of the aminopyridiopyrazinone class of PDE5 inhibitors through modification of the core ring system are described. Five new ring systems are evaluated and features that impart improved potency and improved solubility are delineated.
