Aminoalkyl and acylaminoalkyl ethers, process for their preparation, and their use as bradykinin receptor antagonists Aminoalkyl and acylaminoalkyl ethers which are distinguished by high affinity for the bradykinin B2 receptor and improved solubility in water are described. These aminoalkyl and acylaminoalkyl ethers can be represented by the formula (I) (See Fig. I) in which R1,R2,R3 are alkyl, aryl, alkylaryl, halogen, hydrogen, cycloalkyl, CHO, CO- O-alkyl, COOH; R4,R5 are hydrogen, halogen, alkoxy, nitro, cyano, S-alkyl; n is a number from 1 to 8; R6 is hydrogen, alkyl, alkylalkenyl, alkylaryl; R7 is hydrogen and a substituted or unsubstituted acyl radical. A process for preparing the compounds of the formula (I) is likewise described.

On décrit des éthers aminoalkyliques et acylaminoalkyliques, le procédé de préparation de ces derniers et leur utilisation comme antagonistes du récepteur de la bradykinine. On décrit des éthers aminoalkyliques et acylaminoalkyliques qui se distinguent par leur haute affinité pour le récepteur B2 de la bradykinine et par une plus grande solubilité dans l'eau. Ces éthers aminoalkyliques et acylaminoalkyliques peuvent être représentés par la formule (I) (Voir Fig. I) dans laquelle R1, R2, R3 sont des groupes alkyle, aryle, alkylaryle, un halogène, un hydrogène, un cycloalkyle, CHO, CO- O-alkyle, COOH; R4, R5 sont un hydrogène, un halogène ou un groupe alcoxy, nitro, cyano, S-alkyle; n est un nombre de 1 à 8; R6 est un hydrogène, un alkyle, un alkylalkényle, un alkylaryle; R7 est un hydrogène et un radical acyle substitué ou non substitué. On décrit également un procédé pour préparer les composés de formule (I).
