Abstract

Heterocyclic dihydroxyquinoxaline compounds of the formula <IMAGE> where R1 is hydroxyl, alkoxy, aryloxy, aralkyloxy, cycloalkylalkoxy, cycloalkoxy or acyloxy; R5 and R6 together form an additional fused ring which is substituted by hydrogen, halogen or CN, and R7 and R8 are independently hydrogen, NO2, halogen, CN, SO2NR'R', SO2R', CF3 or OR', where R' is hydrogen or C1-4-alkyl, or R7 and R8 together form an additional fused ring which is substituted by hydrogen, halogen or CN, and R5 and R6 are independently hydrogen, NO2, halogen, CN, SO2NR'R', SO2R', CF3 or OR', where R' is hydrogen or C1-4-alkyl. The invention also relates to a method for preparing the compounds, to pharmaceutical preparations thereof, and to their use. The compounds can be used for treating symptoms caused by hyperactivity of the excitatory neurotransmitters, in particular the quisqualate receptors, and especially as neuroleptics.
