Patent

CA 2249555

Disclosed are compounds of formula (I), or the pharmaceutically acceptable acid addition salts thereof, wherein: R1, R2, R3, R4, R5, R6, R7, R8 and R9 are the same or different and represent hydrogen, C1-C6 alkyl, halogen, hydroxy, amino, cyano, nitro, trifluoromethyl, trifluoromethoxy, C1-C6 alkoxy, -O2CR', -NHCOR', COR', -SOmR', where R' is C1-C6 alkyl and wherein m is 0, 1 or 2; or R1, R2, R3, R4, R5, R6, R7, R8 and R9 independently represent - CONR'R'', or -NR'R'' where R' and R'' independently represent hydrogen or C1- C6 alkyl; R10 is hydrogen or C1-C6 alkyl; and R represents an aminoalkyl group; which compounds are useful in the treatment of affective disorders such as schizophrenia, depression, Alzheimer's disease, movement disorders such as Parkinsonism and dystonia, and other disorders which respond to dopaminergic blockade such as substance abuse and obsessive compulsive disorders. Further, compounds of this invention may be useful in treating the extrapyramidal side effects associated with the use of conventional neuroleptic agents.

L'invention porte sur des composés répondant à la formule (I) ou à leurs sels d'addition d'acide, acceptables du point de vue pharmaceutique. Dans cette formule, R¿1?, R¿2?, R¿3?, R¿4?, R¿5?, R¿6?, R¿7?, R¿8? et R¿9? sont identiques ou différents et représentent un hydrogène, un alkyle en C¿1?-C¿6?, un halogène, un hydroxy, un amino, un cyano, un nitro, un trifluorométhyle, un trifluorométhoxy, un alkoxy en C¿1?-C¿6?, -O¿2?CR', -NHCOR', -COR', -SO¿m?R', R' représentant un alkyle en C¿1?-C¿6?, et m valant 0, 1 ou 2. R¿1?, R¿2?, R¿3?, R¿4?, R¿5?, R¿6?, R¿7?, R¿8? et R¿9? peuvent, également, représenter, indépendamment, -CONR'R'' ou -NR'R''; R' et R'' y représentant indépendamment un hydrogène ou un alkyle en C¿1?-C¿6?. Dans cette même formule, R¿10? représente un hydrogène ou un alkyle en C¿1?-C¿6? et R représente un groupe aminoalkyle. Ces composés s'avèrent utiles dans le traitement de troubles de l'affectivité, comme la schizophrénie, la dépression et la maladie d'Alzheimer, de troubles de la motricité comme le parkinsonisme et la dystonie, ainsi que d'autres troubles découlant d'un blocage dopaminergique, la pharmacodépendance et des troubles obsessionnels de type compulsionnel, par exemple. Les composés selon l'invention sont, de surcroît, efficaces s'agissant de traiter des effets secondaires extrapyramidaux liés à l'emploi d'agents neuroleptiques classiques.
