antagonists based on the dibenzobicyclo[2.2.2]octane (BCO) skeleton which have recently been described were found to show species-dependent behavior when examined in rat and dog models. We now report the discovery of compounds in which the BCO skeleton has been replaced with bicyclic, heteroaromatic frameworks, such as a 5,6-disubstituted indole or benzimidazole. These new ligands maintain the affinity and
最近在大鼠和狗模型中发现,发现了一系列基于二苯并双环[2.2.2]辛烷(BCO)骨架的强效和选择性胆囊收缩素B /胃泌素受体拮抗剂,它们显示出物种依赖性的行为。我们现在报告发现其中BCO骨架已被双环,杂芳族骨架(例如5,6-二取代的吲哚或苯并咪唑)取代的化合物的发现。这些新的配体在体外保持了先前化合物的亲和力和选择性,但在体内却表现出更加一致的行为模式。当以0.1μmol·kg-1或更少的剂量静脉内施用时,已经表明这类化合物的代表性实例抑制五肽胃泌素刺激的酸分泌。
