based on the B2 antagonist D-Arg0-[Hyp3,D-Phe7,Leu8]-BK (1) and the B1 antagonist Lys0-[Leu8,des-Arg9]-BK (7) that are potent antagonists of both B1 and B2 receptors. From this series, compound 50 (alternatively, CP-0364), the 1,6-bis(succinimido)hexane heterodimer of D-Arg0-[Hyp3,Cys6,D-Phe7,Leu8]-BK (2), and D-Arg0-[Cys1,Hyp3,Leu8,des-Arg9]-BK (6), was found to be the most active both in vitro and
我们基于B2拮抗剂D-Arg0- [Hyp3,D-Phe7,Leu8] -BK(1)和B1拮抗剂Lys0- [Leu8,des-Arg9] -BK(7)开发了一系列肽异二聚体是B1和B2受体的有效拮抗剂。从该系列化合物50(或者CP-0364),D-Arg0- [Hyp3,Cys6,D-Phe7,Leu8] -BK(2)和D-的1,6-双(琥珀酰亚胺基)己烷异二聚体发现Arg0- [Cys1,Hyp3,Leu8,des-Arg9] -BK(6)在体外和体内都是最活跃的。当针对缓激肽(BK)诱导的大鼠子宫平滑肌收缩进行测量时,化合物50的pA2为8.3,针对[des-Arg9] -BK诱导的兔主动脉平滑肌收缩的IC50约为10(-8)M。
