Patent

CA 2317536

A pharmaceutical compound of formula (I) in which the aminosulfonyl group is attached at the 3- or 4-position, and in which R1 is hydrogen, C1-6 Alkyl, C3- 10 cycloalkyl, C3-10 cycloalkyl-C1-4 alkyl or optionally substituted phenyl-C1- 4 alkyl, R2 is C1-6 alkyl, C3-10 cycloalkyl, C3-10 cycloalkyl-C1-4 alkyl, optionally substituted phenyl-C1-4 alkyl or -(CH2)2NR5R6 where R5 and R6 are each hydrogen or C1-6 alkyl, and R3 and R4 are each C1-6 alkyl, C3-10 cycloalkyl, C3-10 cycloalkyl-C1-4 alkyl, C3-6 alkenyl, optionally substituted phenyl or optionally substituted phenyl-C1-4 alkyl, or R1 and R2, or R3 and R4, or R5 and R6, together with the nitrogen atom to which they are attached, form a carbocyclic group containing 4 to 7 carbon atoms optionally substituted with one to three methyl or ethyl groups and optionally containing an oxygen atom or a further nitrogen atom, said carbocyclic group being optionally fused to an optionally substituted phenyl group; or a salt thereof.

L'invention se rapporte à un composé pharmaceutique représenté par la formule (I) dans laquelle le groupe aminosulfonyle est attaché en position 3 ou 4 et où R?1¿ est hydrogène, alkyle C¿1?-C¿6?, cycloalkyle C¿3?-C¿10?, cycloalkyle C¿3?-C¿10?-alkyle C¿1?-C¿4? ou phényle-alkyle C¿1?-C¿4?, R?2¿ est alkyle C¿1?-C¿6?, cycloalkyle C¿3?-C¿10?, cycloalkyle C¿3?-C¿10?-alkyle C¿1?-C¿4? ou phényle-alkyle C¿1?-C¿4? ou (CH¿2?)¿2?NR?5¿R?6¿ où R?5¿ et R?6¿ sont chacun hydrogène ou alkyle C¿1?-C¿6?, et R?3¿ et R?4¿ sont chacun alkyle C¿1?-C¿6?, cycloalkyle C¿3?-C¿10?, cycloalkyle C¿3?-C¿10?-alkyle C¿1?-C¿4?, alcényle C¿3?-C¿6?, phényle éventuellement substitué ou phényle-alkyle C¿1?-C¿4? éventuellement substitué, ou bien R?1¿ et R?2¿, ou R?3¿ et R?4¿, ou R?5¿ et R?6¿ forment conjointement à l'atome d'azote auquel ils sont attachés, un groupe carbocyclique contenant 4 à 7 atomes de carbone éventuellement substitués par un à trois groupes méthyle ou éthyle et contenant éventuellement un atome d'oxygène ou un autre atome d'azote, ledit groupe carbocyclique étant éventuellement fusionné à un groupe phényle éventuellement substitué. L'invention se rapporte également à un sel de ce composé.
