Substituted thiophenecarboxylic acid and esters and pharmaceutically acceptable salts thereof of the following general structure are useful as hypolipidemic agents: ##STR1## wherein Y is selected from oxygen and divalent sulfur; R is selected from a straight or branched saturated hydrocarbon chain of from 10 to 20 carbon atoms and a straight or branched unsaturated hydrocarbon chain containing from 10 to 20 carbon atoms and from 1 to 4 double bonds; R.sub.1 is selected from hydrogen, a straight or branched lower alkyl group of from 1 to 6 carbon atoms, benzyl, phenethyl, alkane-poly-yl containing from 3 to 6 carbon atoms, and 1,2,3,4,5,6-cyclohexanehexayl; X is an integer of from 1 to 6 with the proviso that when R.sub.1 is alkane-poly-yl or 1,2,3,4,5,6-cyclohexanehexayl, X is equal to from 2 to 6, and when R.sub.1 is other than alkane-poly-yl or 1,2,3,4,5,6-cyclohexanehexayl, X is equal to 1.
以下一般结构的硫代苯甲酸和酯及其药用可接受的盐可用作降脂药物: ##STR1## 其中Y从氧和二价硫中选择;R从由10到20个碳原子组成的直链或支链饱和碳氢链和由10到20个碳原子和1到4个双键组成的直链或支链不饱和碳氢链中选择;R.sub.1从氢、由1到6个碳原子组成的直链或支链低碳烷基、苄基、苯乙基、含有3到6个碳原子的烷基聚基和1,2,3,4,5,6-环己烷六基中选择;X是一个从1到6的整数,但当R.sub.1是烷基聚基或1,2,3,4,5,6-环己烷六基时,X等于2到6,当R.sub.1不是烷基聚基或1,2,3,4,5,6-环己烷六基时,X等于1。
