tests using a lethal dose of compound 48/80 (a potent histamine-releasing agent) demonstrated that triprolidine itself was the most active compound to protect the animal among all the isomeric compounds tested: in all isomeric pairs the E-configuration possessed superior activity over Z. The disposition of the aryl groups in these geometrically constrained compounds mimics that seen in the structurally
据报道一些与曲普利定有关的几何异构体的合成。通过高场核Overhauser增强方法验证了先前通过UV和质子NMR进行的构型分配,并且通过针对这些化合物开发的HPLC方法评估,测试的E和Z异构体的异构体纯度大于99.5%。豚鼠回肠中曲普立啶的亲和常数(E和Z)显示效价比约为600,而在小脑部位,该比值仅为约100,这表明这两个组织中的H1受体可能不同。使用致死剂量的化合物48/80(一种有效的组胺释放剂)进行的体内试验表明,在所有受测的同分异构化合物中,曲普立啶本身是保护动物活性最高的化合物:
