The design, synthesis, and structure-activity relationships (SAR) for the development of selective dipeptoid ligands for both of the cholecystokinin (CCK) receptor subtypes CCK-A and CCK-B are described. The SAR developed is used to design a ligand with equal nanomolar binding affinity for both the CCK-A and CCK-B receptors. Example compounds such as [1R-[1 alpha[R*(R*)],2 beta]]-4-[[2-[[3-(1H-indol-3-yl)-
描述了开发胆囊收缩素(CCK)受体亚型CCK-A和CCK-B的选择性二肽配体的设计,合成和结构活性关系(SAR)。开发的SAR用于设计对CCK-A和CCK-B受体均具有相同纳摩尔结合亲和力的配体。示例化合物,例如[1R- [1 alpha [R *(R *)],2 beta]]-4-[[2-[[3-(1H-吲哚-3-基)-2-甲基-2- [[[((2-甲基环己基)氧基]羰基]氨基] -1-氧丙基]-氨基] -1-苯基乙基]氨基] -4-氧代丁酸(24c),(1R-反式)-N-α -甲基-N-[[((2-甲基环己基)氧基]羰基] -D-色氨酸] -L-3-(苯甲基)-β-丙氨酸(28i)和N- [α-甲基-N-[(三环) [3.3.1.1]癸-2-基氧基)羰基] -D-色氨酸] -L-3-(苯甲基)-β-丙氨酸(30m)是具有CCK-B结合亲和力为IC50 = 3.9的CCK-B选择性化合物,
