Compounds of formula (I) or salt thereof or solvate thereof, in which: m is 1 or 2; n is 1 or 2; X is CH or N; Y is selected from hydrogen, halogen, cyano, CF3, alkyl or alkoxy; R1, which may be at any position within the saturated ring system, is hydrogen or up to two substituents which may be the same or different and each of which is selected from fluoro and C1-6 alkyl; R2 is hydrogen or up to four substituents selected from halogen, NO2, CN, N3, CF3O-, CF3S-, CF3CO-, C1-6alkyl, C1-6alkenyl, C1-6alkynyl, C1-6perfluoroalkyl, C3- 6cycloalkyl, C3-6cycloalkyl-C1-4alkyl-, C1-6alkylO-, C1-6-alkylCO-, C3- 6cycloalkylO-, C3-6cycloalkylCO-, C3-6cycloalkyl-C1-4alkylO-, C3-6cycloalkyl- C1-4alkylCO-, phenyl, phenoxy, benzyloxy, benzoyl, phenyl-C1-4alkyl-, C1- 6alkylS-, C1-6alkylSO2-, (C1-4alkyl)2NSO2-, (C1-4alkyl)NHSO2-, (C1-4alkyl)2NCO- , oxazolyl, (C1-4alkyl)NHCO-, CONH2; or R4CONH- or -NR4R5, wherein R4 is hydrogen or C1-4 alkyl; and R5 is hydrogen, C1-4alkyl, formyl, -CO2C1-4alkyl or -COC1-4alkyl; or two R2 groups are linked together form a carbocyclic or heterocyclic ring that is saturated or unsaturated and unsubstituted or substituted by -OH or =O are indicated to be useful in the treatment and pophylaxis of epilepsy, migraine, and other disorders.

La présente invention concerne des composés représentés par la formule (I), ou bien un sel ou un solvate de ces composés, qui conviennent pour le traitement et la prophylaxie de l'épilepsie, de la migraine et autres troubles. Selon cette formule (I), m vaut 1 ou 2; n vaut 1 ou 2; X est CH ou N; Y est pris dans hydrogène, halogène, cyano, CF¿3?, alkyle ou alkoxy; R?1¿, qui peut occuper n'importe quelle position dans le cycle saturé, est hydrogène ou jusqu'à deux substituants, identiques ou différents, pris chacun dans fluoro et alkyle en C¿1-6?; R?2¿ est hydrogène ou jusqu'à quatre substituants pris dans halogène, NO¿2?, CN, N¿3?, CF¿3?O-, CF¿3?S-, CF¿3?CO-, alkyle en C¿1-6?, alcényle en C¿1-6?, alkynyle en C¿1-6?, perfluoroalkye en C¿1-6?, cycloalkyle en C¿3-6?, C¿3-6?cycloalkyle C¿1-4?alkyle-, C¿1-6?alkylO-, C¿1-6? alkylCO-, C¿3-6?cycloalkylO-, C¿3-6?cycloalkylCO-, C¿3-6?cycloalkyle C¿1-4?alkylO-, C¿3-6 ?cycloalkyle C¿1-4?alkylCO-, phényle, phénoxy, benzyloxy, benzoyl, phényl-C¿1-4?alkyl, C¿1-6?alkylS-, C¿1-6? alkylSO¿2?-, (C¿1-4?alkyl)¿2?NSO¿2?-, (C¿1-4?alkyl)NHSO¿2?-, (C¿1-4?alkyl)¿2?NCO-, oxazolyl, (C¿1-4?alkyl)NHCO-, CONH¿2? ; ou R?4¿CONH- ou -R?4¿R?5¿, où R?4¿ est hydrogène ou alkyl en C¿1-4? ; et R?5¿ est hydrogène, alkyle en C¿1-4?, formyl, -CO¿2?C¿1-4?alkyle ou COC¿1-4?alkyle ; ou deux groupes R?2¿ liés et formant un atome carbocyclique ou hétérocyclique, saturé ou insature, substitué ou non par -O¿1?H ou =O.
