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.

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

Important targets for the prevention and treatment of diabetic complications include aldose reductase (AR) inhibitors (ARIs) and inhibitors of advanced glycation endproduct (AGE) formation. Here we evaluate the inhibitory activities of prenylated flavonoids isolated from Sophora flavescens, a traditional herbal
