study, we have investigated the effects of replacement of the D-Tic-Oic moiety by various constrained dipeptide mimetics. The resulting compounds were tested for their binding affinity toward the cloned human B(2) receptor and for their functional interaction with the bradykinin-induced contraction of isolated human umbilical vein. Subsequently, we have designed novel bradykinin B(2) receptor agonists
先前我们已经证明了D-Tic-Oic二肽被(3S)-[氨基] -5-(羰基甲基)-2,3-二氢-1,5-苯并噻唑啉-4(5H)-一个(D -BT)缓激肽B(2)受体拮抗剂HOE 140中的部分导致了完全有效和选择性的缓激肽B(2)受体激动剂(H-DArg-Arg-Pro-Hyp-Gly-Thi-Ser-D-BT- Arg-OH,JMV1116)对人受体具有高亲和力(K(i)0.7 nM)。在本研究中,我们研究了各种约束的二肽模拟物替代D-Tic-Oic部分的影响。测试了所得化合物对克隆的人B(2)受体的结合亲和力以及与缓激肽诱导的孤立人脐静脉收缩的功能相互作用。后来,我们设计了新型缓激肽B(2)受体激动剂,它们可能对内肽酶的酶促裂解具有抗性,并且可能代表了有趣的新药理学工具。为了增加化合物JMV1116的效力,其N端部分和D-BT部分都被修饰。D-精氨酸残基被L-赖氨酸残基取代导致更有效的
