Eriodictyol

Eriodictyol is a flavonoid isolated from the Chinese herb, with antioxidant and anti-inflammatory activity. Eriodictyol induces Nrf2 signaling pathway. Eriodictyol is also a potent influenza RNA-dependent RNA polymerase inhibitor with an IC50 of 18 nM.

How to use

In Vitro:

Eriodictyol is a flavonoid isolated from the Chinese herb, with antioxidant and anti-inflammatory activity. Eriodictyol (20, 40, 80 μM) protects primary cultured cortical neurons against Aβ25-35-induced cytotoxicity and cell apoptosis via the Nrf2/ARE pathway. Eriodictyol (80 μM) induces nuclear expression of Nrf2 and the expression of ARE-regulated genes in primary cultured cortical neurons.

In Vivo:

Eriodictyol shows protective effect against LPS-induced acute lung injury (ALI). Eriodictyol (30 mg/kg, p.o.) decreases the production of inflammatory cytokines, elevates survival rate, and decreases oxidative stress levels in LPS-induced ALI mice. Eriodictyol inhibits MPO activity and inflammatory neutrophil accumulation in the lung tissues. Eriodictyol treatment also enhances Trx1 expression by upregulating the Nrf2 expression in lung tissues.
