Biological Activity for (±)-Eriodictyol

(±)-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.
