3-substituted 5-phenyl-1,4-benzodiazepines, nonpeptidal antagonists of the peptide hormone cholecystokinin (CCK), have been synthesized. Designed on the basis of facts regarding CCK, its natural-product antagonist asperlicin (3), and the antianxiety agent diazepam (4), these compounds represent a significant departure from existing CCK antagonists. They also constitute perhaps the first examples of simple
已经合成了一系列3-取代的5-苯基-1,4-苯并二氮杂卓,它们是肽激素胆囊收缩素(CCK)的非肽拮抗剂。根据有关CCK,其天然产物拮抗剂Asperlicin(3)和抗焦虑药地西epa(4)的事实进行设计,这些化合物与现有的CCK拮抗剂有很大的不同。它们也可能构成通过设计而不是通过筛选产生的肽受体的简单,非肽配体的第一个实例。这些化合物用于阐明中枢和外周CCK受体之间的区别,并提供具有潜在药理或治疗用途的口服有效CCK拮抗剂。他们的受体亲和力的一个基本原理可能会在设计其他受体的非肽配体时应用,
