A series of 5-phenyl-3-ureidobenzazepin-2-one cholecystokinin-B (CCK-B) receptor antagonists was synthesized using Beckmann ring expansion of a suitable 4-phenyl-1-tetralone as a key step. Structure-activity relationship studies revealed the importance of the 5-phenyl group for potent and selective CCK-B affinity. Addition of an 8-methyl substituent and resolution provided the potent (CCK-B IC50 =
使用合适的4-苯基-1-四氢萘酮的贝克曼环扩展作为关键步骤,合成了一系列5-苯基-3-脲基苯并ze庚因-2-酮胆囊收缩素-B(CCK-B)受体拮抗剂。结构-活性关系研究揭示了5-苯基对于有效和选择性CCK-B亲和力的重要性。添加8-甲基取代基和拆分提供了有效的(CCK-B IC50 = 0.48 nM)CCK-B拮抗剂4。5-苯基作为高亲和力受体拮抗作用的“特权结构”的一部分的作用是讨论过。
