                                摘要:
                                Design and synthesis of pyrazolodihydropyrimidines as K(V)1.5 blockers led to the discovery of 7d as a potent and selective antagonist. This compound showed atrial selective prolongation of effective refractory period in rabbits and was selected for clinical development. (C) 2010 Elsevier Ltd.
