and Ar in the above formula are defined herein. Such compounds may be used to modulate ligand binding to GABA
A
receptors in vivo or in vitro, and are particularly useful in the treatment of a variety of central nervous system (CNS) disorders in humans, domesticated companion animals and livestock animals. Compounds provided herein may be administered alone or in combination with one or more other CNS agents to potentiate the effects of the other CNS agent(s). Pharmaceutical compositions and methods for treating such disorders are provided, as are methods for using such ligands for detecting GABA
A
receptors (e.g., receptor localization studies).
本发明提供了公式为的化合物,以及它们的制备方法。上述公式中的变量Z1、Z2、R3、Z4、R5、R6、R7、R8和Ar在此定义。这些化合物可用于体内或体外调节GABAA受体的配体结合,并在治疗人类、家养伴侣动物和家畜动物的各种中枢神经系统(CNS)疾病方面特别有用。本文提供的化合物可单独或与一种或多种其他CNS药物联合使用,以增强其他CNS药物的效果。本文还提供了用于治疗此类疾病的制药组合物和方法,以及用于检测GABAA受体的配体的使用方法(例如,受体定位研究)。
