Eleutheroside B1, a coumarin compound, has broad-spectrum anti-human influenza virus (influenza virus) activity with IC50 values of 64-125μg/ml. It mediates its anti-influenza activity through POLR2A and N-glycosylation. Eleutheroside B1 inhibits mRNA expression of multiple chemokine genes and influenza virus nucleoprotein (NP) gene with low cytotoxicity. Has antiviral and anti-inflammatory activity.
