    • The present invention relates to [1,2,4]triazolo[4,3-a quinoxaline derivatives of formula I ##STR1## wherein one of R.sup.1 and R.sup.2 is a 5- or 6-membered nitrogen-containing heterocyclic ring which is optionally substituted with one, two or three substituents, wherein each substituent is independently phenyl or C.sub.1-6 -alkyl, or one of R.sup.1 and R.sup.2 is a fused ring system comprising a 5- or 6-membered nitrogen-containing heterocyclic ring and a benzene, pyridine, pyrimidine or pyrazine ring, wherein the fused ring system is optionally substituted with phenyl or C.sub.1-6 -alkyl; and the other of R.sup.1 and R.sup.2 is hydrogen, C.sub.1-6 -alkyl, C.sub.1-6 -alkoxy, halogen, NO.sub.2, NH.sub.2, CN, CF.sub.3, COC.sub.1-6 -alkyl or SO.sub.2 NR'R", wherein R' and R" are independently hydrogen or C.sub.1-6 -alkyl; and X is O or S; and pharmaceutically acceptable salts thereof. The compounds have affinity for the AMPA receptors and are antagonists in connection with this type of receptors which makes them useful in the treatment of CNS ailments, especially in the treatment of any of the numerous indications caused by hyperactivity of excitatory amino acids.
    • 本发明涉及式Ⅰ化合物[1,2,4]三唑并[4,3-a喹喔啉衍生物,其中R 1和R 2之一为5-或6-元含氮杂环,其中 任选地被一个,两个或三个取代基取代,其中每个取代基独立地是苯基或C 1-6 - 烷基,或者R 1和R 2中的一个是包含5或6元含氮杂环的稠环体系和 苯,吡啶,嘧啶或吡嗪环,其中稠环体系任选被苯基或C 1-6 - 烷基取代; R 1和R 2中的另一个为氢,C 1-6 - 烷基,C 1-6 - 烷氧基,卤素,NO 2,NH 2,CN,CF 3,COC 1-6 - 烷基或SO 2 NR'R“ '独立地是氢或C 1-6 - 烷基; X为O或S; 及其药学上可接受的盐。 这些化合物对AMPA受体具有亲和力,并且是与这种类型的受体有关的拮抗剂,这使得它们可用于治疗CNS疾病,特别是在治疗由兴奋性氨基酸的多动症引起的许多适应症中的任何一种。
