Succinic acid compounds of the formula: ##STR1## wherein A represents a heterocyclic group, a 3 to 8-membered cycloalkyl group or a phenyl group which may have one or more substituents selected from the group of a halogen atom, a lower alkyl group having 1 to 6 carbon atoms and a lower alkoxy group having 1 to 6 carbon atoms; B represents a bicyclic amino group which may have 1 or 2 unsaturated bonds, with the proviso that B bonds to the carbon atom of the carbonyl group at the nitrogen atom; R represents a hydrogen atom or combines each other to form a chemical bond; R.sup.1 represents a hydrogen atom, a lower alkyl group having 1 to 6 carbon atoms or an aralkyl group having 7 to 10 carbon atoms; when there is an asymmetric carbon atom, enantiomers thereof and racemic mixtures thereof; when there are geometrical isomers, each geometrical isomer, E-isomers thereof, Z-isomers thereof, cis-isomers thereof and trans-isomers thereof; and pharmaceutically acceptable salts thereof, enhance insulin secretion and possess a hypoglycemic activity, and are thus useful for the treatment of diabetes.
分子式为:##STR1##的琥珀酸化合物,其中A代表杂环基团、3至8个成员的环烷基团或苯基团,其可具有来自卤素原子、1至6个碳原子的低烷基团和1至6个碳原子的低烷氧基团等基团的一个或多个取代基;B代表一个含有1或2个不饱和键的双环氨基团,但B必须与氮原子的羰基团上的碳原子成键;R代表氢原子或结合在一起形成化学键;R.sup.1代表氢原子、1至6个碳原子的低烷基团或7至10个碳原子的芳基烷基团;当存在不对称碳原子时,其对映异构体和外消旋混合物;当存在几何异构体时,每个几何异构体、E-异构体、Z-异构体、顺式异构体和反式异构体;以及其药学上可接受的盐,可以增强胰岛素分泌并具有降血糖作用,因此可用于治疗糖尿病。
