A heterocyclic compound selected from those of formula (1), tautomers thereof, and pharmaceutically acceptable salts and esters of formula (I) compounds and tautomers:
wherein A represents an alkylene or alkenylene chain which has 1 to 4 carbon atoms and which may have a hetero atom; B, D and Y are selected independently from oxygen and sulfur atoms and NH; R' and R2 are selected independently from hydrogen and halogen atoms and C, to C5 alkyl, C, to C5 alkoxy, C, to C5 alkylthio, phenyl, nitro, hydroxyl, sulfo, imidazolyl-C2 to C5 acylamimo, amino and carboxyl groups; and R3 represents a hydrogen atom, an amino group, a C1 to C5 alkyl group which may be substituted by a carboxyl group, or a phenyl group which may be substituted by a carboxyl, a carboxy-C1 to C5 alkyl, or an imidazolyl-C, to C5 alkylamide group. These compounds, particularly when D is oxygen, are aldose reductose inhibitors useful in treatment of chronic diabetic complications.
选自式(1)的杂环化合物、其同系物以及式(I)化合物和同系物的药学上可接受的盐和酯:
其中 A 代表具有 1 至 4 个碳原子且可能具有杂原子的亚烷基或烯基链;B、D 和 Y 独立选自氧原子、硫原子和 NH;R'和 R2 独立选自氢原子、卤素原子和 C 至 C5 烷基、C 至 C5 烷氧基、C 至 C5 硫代烷基、苯基、硝基、羟基、磺基、咪唑基-C2 至 C5 氨基酰基、氨基和羧基;R3 代表氢原子、氨基、可被羧基取代的 C1 至 C5 烷基或可被羧基、羧基-C1 至 C5 烷基或咪唑基-C1 至 C5 烷酰胺基取代的苯基。这些化合物,特别是当 D 为氧时,是醛糖还原糖抑制剂,可用于治疗慢性糖尿病并发症。
