Aldose reductase inhibitors of the formula ##STR1## in which R.sup.1 is CH.sub.2 COOR.sup.4 wherein R.sup.4 is hydrogen or lower alkyl; R.sup.2 is COOR.sup.5 wherein R.sup.5 is hydrogen or lower alkyl; and R.sup.3 is lower alkoxy, benzyloxy or CH.sub.2 COOR.sup.6 wherein R.sup.6 is hydrogen or lower alkyl; with the provisos that when R.sup.4 is hydrogen then R.sup.5 and R.sup.6 is hydrogen; and that when R.sup.4 is lower alkyl then R.sup.5 and R.sup.6 are lower alkyl with R.sup.4 and R.sup.6 being the same lower alkyl; are useful for treating diabetic complications.
具有以下结构的醛糖还原酶抑制剂##STR1##其中R.sup.1为CH.sub.2 COOR.sup.4,其中R.sup.4为氢或较低的烷基;R.sup.2为COOR.sup.5,其中R.sup.5为氢或较低的烷基;R.sup.3为较低的烷氧基,苄氧基或CH.sub.2 COOR.sup.6,其中R.sup.6为氢或较低的烷基;但需注意,当R.sup.4为氢时,R.sup.5和R.sup.6为氢;当R.sup.4为较低的烷基时,R.sup.5和R.sup.6为较低的烷基,其中R.sup.4和R.sup.6为相同的较低的烷基;此类化合物可用于治疗糖尿病并发症。
