CA 2255884

Novel 5-alkoxy tryptamine derivatives are provided, correponding to general formula (I) wherein n is an integer from 1 - 3; R represents a straight or branched C1-C9 alkylene chain optionally interrupted by a phenylene group; X represents amino, mono(loweralkyl)amino, di(loweralkyl)amino or optionally N- lower alkyl-substituted pyrrolidine; and Y represents optionally substituted phthalimide, benzosulfonimide, naphthosultam, naphthalimide, isoindolone camphorsultam, toluenesulfonamido, N, N'-dicarboxylated guanidino or N- carboxylated amino, each of which is linked to R via a respective N-group thereof. The compounds show selective binding to 5-HT1D receptor subtypes, and have potential pharmaceutical utility in manufacture of migraine-treating drugs.

On décrit de nouveaux dérivés de 5-alcoxy-tryptamine répondant à la formule générale (I), où n est un entier de 1 à 3; R représente une chaîne alkylène linéaire ou ramifiée C1-C9 éventuellement interrompue par un groupe phénylène; X représente un amino, mono(alkyle inférieur)amino, di(alkyle inférieur)amino ou pyrrolidine éventuellement substituée par N-alkyle inférieur; et Y représente, chacun d'eux étant lié à R par leur groupe N respectif, un phtalimide, benzosulfonimide, naphtosultame, naphtalimide, iso-indolone, camphorsultame, toluènesulfonamido, chacun éventuellement substitué, un guanidino N, N'-dicarboxylé ou un amino N-carboxylé. Ces composés présentent une liaison sélective aux récepteurs de sous-type 5-HT1D et peuvent être utiles sur le plan pharmaceutique dans la fabrication de médicaments contre la migraine.
