PHENOXYALKANECARBOXYLIC-ACID DERIVATIVES, PROCESS FOR THEIR PREPARATION AND MEDICINES CONTAINING THESE COMPOUNDS

摘要

Phenoxyalkylcarboxylic acid derivatives of the formula I in which the sulfonylaminoalkyl group is in the ortho- or the meta-position to the phenoxyalkylcarboxylic acid group and in which R1 denotes an aryl group, aralkyl group or an aralkenyl group whose aryl radical can in each case be optionally mono- or polysubstituted by halogen, cyano, alkyl, trifluoromethyl, alkoxy, hydroxyl, nitro, amino, alkylamino, dialkylamino, acylamino, acyl, azido or can be substituted by phenyl which is optionally substituted by halogen, cyano, alkyl, trifluoromethyl or alkoxy, R2 represents hydrogen, an alkyl group, aralkyl group or an acyl group, R3 and R4, which can be identical or different, denote hydrogen or a lower alkyl group and n denotes the numbers 1-3, and their physiologically acceptable salts, esters and amides have platelet aggregation-inhibiting and/or hypolipidaemic action.
