A novel series of cholecystokinin-2 receptor (CCK-2R) antagonists has been identified, as exemplified by anthranilic sulfonamide 1 (pK(i)=7.6). Pharmacokinetic and stability studies indicated that this series of compounds suffered from metabolic degradation, and that both the benzothiadiazole and piperidine rings were rapidly oxidized by liver enzymes. A combination of synthesis, computational methods
已经确定了一系列新的胆囊收缩素2受体(CCK-2R)拮抗剂,例如邻氨基苯甲酰胺1(pK(i)= 7.6)。药代动力学和稳定性研究表明,该系列化合物遭受代谢降解,并且苯并噻二唑和哌啶环均被肝酶快速氧化。合成,计算方法,(1)1 H NMR构象研究和X射线晶体学分析相结合,以阐明关键药效基团元素,并发现具有改进的药代动力学特征,高受体结合亲和力和选择性的类似物。
