The use of a dipeptide library as the source of a micromolar chemical lead compound for the human tachykinin NK3 receptor is described. The screening of a dipeptide library through a cloned human NK3 receptor binding assay resulted in the identification of Boc(S)Phe(S)PheNH2 (1), which has subsequently been developed, following a 'peptoid' design strategy, into a series of high-affinity NK3 receptor
描述了使用二肽文库作为人速激肽NK3受体的微摩尔化学先导化合物的来源。通过克隆的人NK3受体结合测定法筛选二肽文库,鉴定出Boc(S)Phe(S)PheNH2(1),随后按照``拟肽''设计策略将其开发为一系列高亲和力的NK3受体选择性拮抗剂。首先探讨了该二肽铅的C末端部分的结构活性关系,并导致鉴定出尿素衍生物Boc(S)Phe(R)alphaMePheNH(CH2)7NHCONH2(41,PD157672)。这种修饰的二肽在阻止senktide诱导的CHO细胞中稳定表达的人NK3受体的细胞内钙水平增加方面具有7 nM的Ke。N端BocPhe基团和41的alphaMePhe残基侧链的后续优化导致[S-(R *,S *)]-[2-(2,3-二氟苯基)-1-甲基-1 -[(7-脲基庚基)氨基甲酰基]乙基]氨基甲酸2-甲基-1-苯基丙酯(60,PD161182),一种非肽NK3受体选择性拮抗剂。
