Title (EN) IMIDAZOQUINOXALINE COMPOUNDS, THEIR PREPARATION AND USE
(FR) COMPOSES D'IMIDAZOQUINOXALINE, LEUR PREPARATION ET EMPLOI
Abstract:
(EN) New imidazoquinoxaline compounds having general formula (I), wherein Q is (a) or (b), wherein R1 and R?2 independently are hydrogen, straight or branched C1-6-alkyl or C3-7-cycloalkyl; R3 is hydrogen, straight or branched C1-6-alkyl, straight or branched C2-6-alkenyl, or aralkyl or aroylalkyl which may optionally be substituted with halogen or C1-6-alkoxy; R4 and R5 independently are hydrogen, halogen, C1-6-alkyl or trifluoromethyl. The compounds are useful in psychopharmaceutical preparations as anticonvulsants, anxiolytics, hypnotics and in improving the cognitive function of the brain of mammals.
(FR) Nouveaux composés d'imidazoquinoxaline ayant la formule générale (I) dans laquelle Q représente (a) ou (b), dans lesquelles R1 et R2 représentent indépendamment hydrogène, alkyle droit ou ramifié contenant 1 à 6 atomes de carbone, cycloalkyle contenant 3 à 7 atomes de carbone; R3 représente hydrogène, alkyle droit ou ramifié contenant 1 à 6 atomes de carbone, alcényle droit ou ramifié contenant 2 à 6 atomes de carbone, ou aralkyle ou aroylalkyle pouvant être facultativement remplacés par halogène ou alkoxy contenant 1 à 6 atomes de carbone; R4 et R5 représentent indépendamment hydrogène, halogène, alkyle contenant 1 à 6 atomes de carbone ou trifluorométhyle. Les composés sont utiles dans des préparations psychopharmaceutiques en tant qu'anticonvulsants, anxiolytiques, hypnotiques, et pour améliorer la fonction cognitive du cerveau de mammifères.
