The compounds of this invention which have the formula: ##STR1## wherein: R.sup.1 and R.sup.2 are independently hydrogen, C.sub.1 -C.sub.8 alkyl, halogen, C.sub.1 -C.sub.8 alkoxy, or trifluoromethyl; R.sup.3 is --OH or --NHCO.sub.2 CH.sub.3 ; X is --CH.sub.2 -- or --OCH.sub.2 --; n is 1 or 2; or a pharmaceutically acceptable salt thereof, are useful in treating or inhibiting the long-term complications of diabetes such as diabetic retinopathy, nephropathy and neuropathy through the inhibition of the enzyme aldose reductase. Aldose reductase inhibitors have been shown to prevent the biochemical, functional and morphological changes induced by hyperglycemia.
本发明的化合物具有以下公式:##STR1## 其中:R.sup.1 和 R.sup.2 独立地是氢、C.sub.1 -C.sub.8 烷基、卤素、C.sub.1 -C.sub.8 烷氧基或三氟甲基;R.sup.3 是--OH或--NHCO.sub.2 CH.sub.3;X 是--CH.sub.2--或--OCH.sub.2--;n 是1或2;或其药用盐,用于治疗或抑制糖尿病的长期并发症,如糖尿病视网膜病变、肾病和神经病变,通过抑制醛糖还原酶酶。已经证明醛糖还原酶抑制剂可以预防高血糖引起的生化、功能和形态学变化。
