Application

Epalrestat has been used as an aldose reductase inhibitor:
  • in the dahomey larvae diet fed forDrosophila
  • for non-irradiated and X-ray irradiated human aldose reductase
  • to test its protective effect in mice with bleomycin-induced pulmonary fibrosis

Biochem/physiol Actions

Epalrestat inhibits Aldose Reductase (AR) involved in the rate limiting step in the conversion of glucose to sorbitol under hyperglycemic conditions. Aldose reductase has been the target of multiple clinical investigatons to treat diabetic neuropathy and retinopathy. Epalrestat is an approved drug in Japan and India, used for the treatment of diabetic neuropathy.

Many observations report the cardioprotective effects of inhibitors of aldose reductase in different models of ischaemia-reperfusion injury in diabetic myocardium. In this paper, the inhibitory effects of the new pyrido[1,2-a]-pyrimidin-4-one derivative PPO, whose aldose reductase-inhibitory and antioxidant effects were shown

Epalrestat is a carboxylic acid derivative which inhibits aldose reductase, an enzyme of the sorbitol (polyol) pathway. Under hyperglycaemic conditions epalrestat reduces intracellular sorbitol accumulation, which has been implicated in the pathogenesis of late-onset complications of diabetes mellitus. Epalrestat 150
