  Novel pyrazolo[1,5-a]pyrimidines as c-Src kinase inhibitors that reduce IKr channel blockade

  摘要：

  To improve the in vitro potency of the c-Src inhibitor 1a and to address its hERG liability, a structure-activity study was carried Out, focusing on two regions of the lead compound. The blockade of the delayed cardiac current rectifier K+ (I-Kr) channel was overcome by replacing the ethylenediamino group with an amino alcohol group at the 7-position. In addition, modifying the substituents at the 5-position and the side chain groups on the amino alcohols at the 7-position enhanced the intracellular c-Src inhibitory activity and increased central nervous system (CNS) penetration. In the present study, 6l exhibited significant in vivo efficacy in a middle cerebral artery (MCA) occlusion model in rats. (C) 2007 Elsevier Ltd. All rights reserved.
