Product Details

Biological Activity

(±)-Eriodictyol is a potent TRPV1 antagonist. Inhibits capsaicin (Cat. No. 0462) -induced Ca2+ influx in synaptosomes. Exhibits antinociceptive activity in animal models without affecting body temperature. Also antioxidant; protects against H2O2-induced neurotoxicity in vitro by activation of Nrf2/ARE signaling. Modeling studies predict binding to ACE2 preventing its interaction with SARS-CoV-2 S protein. Naturally-derived flavonoid. Orally bioavailable.

Technical Data

Soluble to 100 mM in DMSO and to 50 mM in ethanol
Store at -20°C

Additional Information

Other Product-Specific Information:
Although the natural (S)-enantiomer of Eriodictyol may be predominant, this molecule is prone to racemization in solution and will therefore be offered and displayed with undefined stereochemistry.
