Disclosed are compounds of compounds of the formula: or the pharmaceutically acceptable nontoxic salts thereof wherein: X is oxygen, H.sub.2 or sulfur Y is hydrogen, or optionally substituted alkyl, alkenyl, (substituted)arylalkyl, aryl or heteroaryl, or a carbonyl group substituted with alkyl, cycloalkyl, aryl, or amino groups; W is alkyl, arylalkyl or heteroarylalkyl, where each aryl group is optionally substituted with up to two groups; or W is aryl, thienyl, pyridyl or heteroaryl, each of which is optionally substituted; and Z.sub.1, Z.sub.2, Z.sub.3, and Z.sub.4 independently represent nitrogen or C-R.sub.1 where R.sub.1 is hydrogen, halogen, hydroxy, amino, or phenyl or pyridyl optionally mono- or independently disubstituted with halogen, hydroxy, lower alkyl, or lower alkoxy, which compounds are highly selective agonists, antagonists or inverse agonists for GABAa brain receptors or prodrugs of agonists 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 enhancement of memory.
本发明涉及一类化合物,其化学式为:或其药学上可接受的无毒盐,其中:X为氧、H.sub.2或硫,Y为氢或可选的取代烷基、烯基、(取代)芳基烷基、芳基或杂环芳基,或取代烷基、环烷基、芳基或氨基基团的羰基基团;W为烷基、芳基烷基或杂环芳基烷基,其中每个芳基组分别可选地取代最多两个基团;或W为芳基、噻吩基、吡啶基或杂环芳基,每个基团可选地取代;且Z.sub.1、Z.sub.2、Z.sub.3和Z.sub.4分别独立地表示氮或C-R.sub.1,其中R.sub.1为氢、卤素、羟基、氨基或苯基或吡啶基,可选地单独或独立地取代卤素、羟基、低烷基或低烷氧基,这些化合物是高度选择性的GABAa脑受体的激动剂、拮抗剂或反向激动剂或GABAa脑受体激动剂或反向激动剂的前药。这些化合物可用于诊断和治疗焦虑、睡眠和癫痫疾病、苯二氮平类药物过量和增强记忆。
