The present invention encompasses structures of the formula I: ##STR1## or the pharmaceutically acceptable non-toxic salts thereof wherein: G represents ##STR2## where Q is aryl substituents optionally mono or disubstituted with hydroxy or halogen; T is halogen, hydrogen, hydroxyl, amino or alkoxy having 1-6 carbon atoms; W is oxygen, nitrogen, sulfur, or optionally substituted methylene; X is hydrogen, hydroxyl, or alkyl; Z is an organic or inorganic substituent optionally forming a ring with subtituents on Q; ##STR3## independently represent optionally substituted carbon chains; wherein k, m, and n are independently 0, or an integer of from 1-3 R.sub.3, R.sub.4, R.sub.5, and R.sub.6 are the same or different and represent organic or inorganic substituents. These compounds are highly selective agonists, antagonists or inverse agonists for GABAa brain receptors or prodrugs of agonists, antagonists or inverse agonists for GABAa brain receptors. These compounds are useful in the diagnosis and treatment of anxiety, sleep and seizure disorders, overdose with benzodiazepine drugs and for enhancement of memory.
本发明涵盖了以下结构的化合物I:##STR1##或其药学上可接受的非毒性盐,其中:G代表##STR2##其中Q是芳基取代物,可选择地是单取代或二取代的羟基或卤素;T是卤素、氢、羟基、氨基或具有1-6个碳原子的烷氧基;W是氧、氮、硫或可选择地取代的亚甲基;X是氢、羟基或烷基;Z是有机或无机取代基,可选择地与Q上的取代基形成环;##STR3##独立地代表可选择地取代的碳链;其中k、m和n独立地为0,或为1-3的整数,R.sub.3、R.sub.4、R.sub.5和R.sub.6相同或不同,代表有机或无机取代基。这些化合物是高度选择性的GABAa脑受体的激动剂、拮抗剂或逆激动剂,或者是GABAa脑受体的激动剂、拮抗剂或逆激动剂的前药。这些化合物在焦虑、睡眠和癫痫障碍的诊断和治疗、苯二氮卓类药物过量和增强记忆方面是有用的。
