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,涉及其制备方法以及用于脂质抑制和血小板聚集的药物组合物,其中包含它们,并且涉及用于治疗由于脂质过多或血小板聚集引起的疾病的方法。根据本发明的新羧酸衍生物是符合以下一般式的化合物:##STR1## 其中A是一个价键或较低的烷基链,B是一个价键或饱和或不饱和的较低烷基链,R是氢,一种可以被羟基,羧基,磺酸基或可选择地取代的苯氧基团取代的烷基团,或者R是一种芳基烷基基团,其芳基部分可以被取代,烷基部分可以是可选择地不饱和的并且可以含有多达4个碳原子,或者R是一种苯乙酰基基团,苯基部分可选择地取代,或者R是由脂肪,芳基脂肪或芳香族羧酸或磺酸衍生的酰基基团,或者R是一种芳基基团,可选择地取代,但当A是一个价键时,R不能是氢,甲基,乙基,羟乙基,苄基或苯基,以及其生理上可接受的盐,酯和酰胺。
