Epalrestat (CAS: 82159-09-9) is the second aldose reductase inhibitor to be introduced worldwide and the first to be launched in Japan. Epalrestat is indicated for the treatment of diabetic neuropathy. It is also being investigated for diabetic retinopathy and nephropathy. Epalrestat is an aldose reductase inhibitor with IC50 of 72 nM.
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 used to prevent, ameliorate, and treat peripheral neuropathy (numbness, pain), vibrational paresthesia, and cardiac abnormality associated with diabetes.
Epalrestat as its representative drug reduces intracellular accumulation of fructose and sorbitol by reversibly inhibiting aldose reductase activity, restores Na+-K+-ATPase and inositol activity, increases NO formation in endothelial cells, inhibits protein kinase C signalling pathway, endothelial cell adhesion, high glucose-mediated neutrophil and endothelial adhesion factor expression and reduces carboxymethyl lysine products in diabetic patients, thus treating diseases such as diabetes and its complications.
