Heterocyclic dihydroxyquinoxaline compounds having the formula ##STR1## wherein R.sup.1 is hydroxy; and R.sup.5 and R.sup.6 together form a fused phenyl, cyclohexyl or pyridyl ring, which is optionally substituted with halogen or CN; and R.sup.7 and R.sup.8 independently are hydrogen, hydroxy, NO.sub.2, halogen, CN, CF.sub.3, C.sub.1-4 -alkoxy, acetyl, SO.sub.2 NHCOCO.sub.2 Et, SO.sub.2 NR'R' or SO.sub.2 R', wherein R' is hydrogen or C.sub.1-4 -alkyl; or R.sup.5 and R.sup.6 independently are hydroxy, hydrogen, NO.sub.2, halogen, CN, CF.sub.3, C.sub.1-4 -alkoxy, acetyl, SO.sub.2 NHCOCO.sub.2 Et, SO.sub.2 NR'R' or SO.sub.2 R', wherein R' is hydrogen or C.sub.1-4 -alkyl; and R.sup.7 and R.sup.8 together form a fused phenyl, cyclohexyl or pyridyl ring which is optionally substituted with halogen or CN. The invention also relates to a method of preparing the compounds, pharmaceutical compositions thereof, and their use. The compounds are useful in the treatment of indications caused by hyperactivity of the excitatory neurotransmitters, particularly the quisqualate receptors, and especially as neuroleptics.
含有以下结构的杂环二羟基喹喔啉化合物,其中R.sup.1为羟基;R.sup.5和R.sup.6共同形成融合的苯基、环己基或吡啶基,可选择地用卤素或CN取代;R.sup.7和R.sup.8独立地为氢、羟基、NO.sub.2、卤素、CN、CF.sub.3、C.sub.1-4-烷氧基、乙酰基、SO.sub.2 NHCOCO.sub.2 Et、SO.sub.2 NR'R'或SO.sub.2 R',其中R'为氢或C.sub.1-4-烷基;或R.sup.5和R.sup.6独立地为羟基、氢、NO.sub.2、卤素、CN、CF.sub.3、C.sub.1-4-烷氧基、乙酰基、SO.sub.2 NHCOCO.sub.2 Et、SO.sub.2 NR'R'或SO.sub.2 R',其中R'为氢或C.sub.1-4-烷基;且R.sup.7和R.sup.8共同形成融合的苯基、环己基或吡啶基,可选择地用卤素或CN取代。本发明还涉及一种制备这些化合物的方法、其制药组合物以及它们的用途。这些化合物在治疗由兴奋性神经递质过度活跃引起的症状中有用,特别是在治疗quisqualate受体,尤其是作为神经阻滞剂方面有用。
