The present invention is concerned with new carboxylic acid derivatives, with processes for the preparation thereof and with pharmaceutical compositions for lipid depression and thrombocyte aggregation, containing them, and to methods for treating infirmaties caused by excess lipids or thrombocyte aggregation. The new carboxylic acid derivatives according to the present invention are compounds of the general formula: ##STR1## wherein A is a valency bond or a lower alkylene chain, B is a valency bond or a saturated or unsaturated lower alkylene chain, R is hydrogen, an alkyl group which can be substituted by hydroxyl, carboxyl, sulphonic acid or optionally substituted phenoxy group, or R is an aralkyl radical, the aryl moiety of which can be substituted and the alkyl moiety of which is optionally unsaturated and can contain up to 4 carbon atoms, or R is a phenacyl radical, the phenyl moiety optionally substituted, or R is an acyl radical derived from aliphatic, araliphatic or aromatic carboxylic or sulphonic acid, or R is an aryl radical optionally substituted with the proviso that when A is a valency bond, R cannot be hydrogen, methyl, ethyl, hydroxyethyl, benzyl or phenyl, and the physiologically acceptable salts, esters and amides thereof.
本发明涉及新的羧酸衍生物,其制备过程以及包含它们的用于脂质降低和血小板聚集的药物组合物,以及治疗由过量脂质或血小板聚集引起的疾病的方法。根据本发明,新的羧酸衍生物是具有以下通式的化合物:
##STR1##
其中A是一个价键或低级烷基链,B是一个价键或饱和或不饱和的低级烷基链,R是氢,可以被羟基,羧基,磺酸或可选的取代的苯氧基取代的烷基基团,或R是一个芳基烷基基团,其中芳基部分可以被取代,烷基部分可选不饱和,可以含有高达4个碳原子,或R是一个苯乙酰基基团,其中苯基部分可选取代,或R是从脂肪族,芳基脂肪族或芳香族羧酸或磺酸派生的酰基基团,或R是一个芳基基团,可选取代,但当A是一个价键时,R不能是氢,甲基,乙基,羟乙基,苯甲基或苯基,并且它们的生理上可接受的盐,酯和酰胺。
