Novel, Achiral 1,3,4-Benzotriazepine Analogues of 1,4-Benzodiazepine-Based CCK2 Antagonists That Display High Selectivity over CCK1 Receptors
摘要:
A series of 1,3,4-benzotritzepine-based CCK2 antagonists have been devised by consideration of the structural features that govern CCK receptor affinity and the receptor subtype selectivity of 1,4-benzodiazepine-based CCK2 antagonists. In contrast to the latter compounds, these novel 1.3.4-benzotriazepines are achiral, yet they display similar affinity for CCK2 receptors to the earlier molecules and are highly selective over CCK1 receptors.
