The present invention is directed to compounds of the following formula I: ##STR1## wherein R, R.sub.1, R.sub.2, R.sub.3, R.sub.4, A, n, X, and Y are as defined hereinafter. The compounds of formula I are useful in treating central nervous system disorders. The compounds are ligands for the BZD binding site on GABA-A receptors, and are thus useful as muscle relaxants, hypnotics/sedatives including sleep-aids, anxiolytics, anticonvulsants/antiepileptics, anti-inebriants, and antidotes for drug overdose (particularly benzodiazepine overdose).
本发明涉及以下式子I的化合物:##STR1## 其中R、R.sub.1、R.sub.2、R.sub.3、R.sub.4、A、n、X和Y的定义如下。式I的化合物在治疗中枢神经系统疾病方面很有用。这些化合物是GABA-A受体上BZD结合位点的配体,因此可用作肌肉松弛剂、催眠药/镇静剂(包括助眠剂)、抗焦虑药、抗癫痫药、抗醉剂和药物过量解毒剂(特别是苯二氮卓过量)。
