Biological Activity
Epalrestat (100 and 200 µM, 24 h) inhibits cell viability and induces cell apoptosis in rat Schwann cells (SCs)[5].
Epalrestat (10 and 50 µM, 24 h) increases intracellular glutathione levels in rat SCs by up-regulating γ-GCS via Nrf2 activation[5].
Epalrestat (50 µM, 16 h) protects SCs from oxidative stress[5].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
-
Cell Line:rat SCs

Concentration:10 or 50 µM
-
Incubation Time:4 h
-
Result:Increased the nuclear level of active Nrf2 by 1.8- and 3.8-fold at 10 and 50 µM, and failed to increase Nrf2 mRNA levels.
Epalrestat (100 mg/kg, i.g., daily for 6 weeks) protects rats from diabetic peripheral nerve injury in diabetic peripheral neuropathy (DPN) model induced by Streptozotocin (HY-13753)[6].
Epalrestat (50 mg/kg, oral gavage, twice a day) reduces cerebral ischemia-induced infarct volume and BBB permeability in mice[7].

Cell viability of BMDMs treated with Epalrestat (2.5-200 μM) for 24 h as detected using a CCK-8 reagent.
Epalrestat purchased from MedChemExpress. Usage Cited in: J Transl Med. 2023 Oct 7;21(1):700. [Abstract]
LPS-primed BMDMs were treated with various doses of Epalrestat (10, 20, 40 μM) for 1 h before stimulation with nigericin for 30 min. Immunoblot analysis of epalrestat was used to detect cleaved caspase-1 and IL-1β in the cell supernatants (Sup.) and the expression of NLRP3, caspase-1 p45, pro-IL-1β, and ASC in the cell lysates (Lys.).

Epalrestat (10, 20, 40 μM) significantly inhibited the production of IL-1β by ELISA.
Epalrestat purchased from MedChemExpress. Usage Cited in: J Transl Med. 2023 Oct 7;21(1):700. [Abstract]
Mice were intraperitoneally injected with LPS or PBS for 6 h after pre-treatment with Epalrestat or vehicle. Peritoneal macrophages pre-treated with Epalrestat (20, 40 mg/kg, i.g.) could also be decrease, as measured via flow cytometry.
Epalrestat purchased from MedChemExpress. Usage Cited in: J Transl Med. 2023 Oct 7;21(1):700. [Abstract]
These pathological changes were significantly reduced after Epalrestat (20 mg/kg, i.g.) treatment stained with H&E, Masson stain, and Sirius red.
