  Pyrrolidine amides of pyrazolodihydropyrimidines as potent and selective KV1.5 blockers

  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. All rights reserved.
