ABSTRACT:
The present invention concerns compounds of the formula: ##STR1## where R.sub.1 is an alkyl or alkenyl radical containing up to 6 carbon atoms, a cycloalkyl radical containing 3 to 7 carbon atoms, an aralkyl, aralkenyl or aryl radical in which the aryl radical or moiety can be substituted one or more times by halogen, C.sub.1 -C.sub.6 -alkyl, C.sub.1 -C.sub.6 -alkoxy, hydroxyl, trifluoromethyl, cyano, nitro, amino, C.sub.1 -C.sub.6 -alkylamino, C.sub.2 -C.sub.12 -dialkylamino, C.sub.1 -C.sub.6 -acylamino, C.sub.1 -C.sub.16 -acyl, C.sub.1 -C.sub.6 -alkylsulphenyl, -sulphinyl or -sulphonyl or by azido, R.sub.2 is hydrogen atom or a C.sub.1 -C.sub.6 -alkyl, aralkyl, aralkenyl or acyl radical, A and B are saturated or unsaturated alkylene chains containing up to 10 carbon atoms which can be substituted one or more times by C.sub.1 -C.sub.3 -alkyl radicals, the sum of carbon atoms in chains A and B being at least 4 and at most 11, Q is an oxygen or sulphur atom, a sulphonyl or sulphinyl group or an amino group --N(R.sub.2)--, R.sub.2 having the same meaning as above, and Y is a free carboxylic acid group or a carboxylic acid ester, carboxylic acid amide, hydroxymethyl or tetrazolyl radical; the pharmacologically acceptable salts thereof and the optically active and E-Z isomers thereof, as well as mixtures thereof.
These compounds are useful as they have an antagonistic action towards thromboxane A.sub.2 as well as against prostaglandin endoperoxide. They inhibit the aggregation of blood platelets and prevent the constriction of the smooth musculature as well as bronchoconstriction.
