  • Experimental Physico-chemical Properties
  • Miscellaneous
    • Target Organs:

      Reductase inhibitor TargetMol T1458
    • Chemical Class:

      A monocarboxylic acid that is 1,3-thiazolidine which is substituted on the nitrogen by a carboxymethyl group, at positions 2 and 4 by thioxo and oxo groups, respectively, and at position 5 by a 2-meth yl-3-phenylprop-2-en-1-ylidene group. It is an inhibitor of aldose reductase (which catalyses the conversion of glucose to sorbitol) and is used for the treatment of some diabetic complications, inclu ding neuropathy. ChEBI CHEBI:31539

      Epalrestat is an aldose reductase inhibitor for the treatment of diabetic neuropathy.;Target: Aldose ReductaseEpalrestat may affect or delay progression of the underlying disease process. Data from six clinical trials were evaluated, and it was determined that epalrestat 50 mg 3 times/day may improve motor and sensory nerve conduction velocity and subjective neuropathy symptoms as compared with baseline and placebo. Epalrestat may serve as a new therapeutic option to prevent or slow the progression of diabetic neuropathy [1]. Epalrestat significantly increased the amplitude of 3 cpm waves on EGG and improved the spectral analytical parameters of heart rate variability. These findings suggest that epalrestat is useful for the treatment of diabetic gastroparesis [2]. Epalrestat is a highly effective and safe agent for the treatment of diabetic neuropathy [3].
