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.

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

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

Diabetic neuropathy is one of the most common long-term complications in patients with diabetes mellitus, with a prevalence of 60-70% in the United States. Treatment options include antidepressants, anticonvulsants, tramadol, and capsaicin. These agents are modestly effective for symptomatic relief

A series of novel sulfonates containing quinazolin-4(3H)-one ring derivatives was designed to inhibit aldose reductase (ALR2, EC 1.1.1.21). Novel quinazolinone derivatives (1-21) were synthesized from the reaction of sulfonated aldehydes with 3-amino-2-alkylquinazolin-4(3H)-ones in glacial acetic acid with good yields (85%-94%).
