 |  | [Uses] 
 Eleutheroside B1, a coumarin compound, has a wide spectrum of anti-human influenza virus efficacy, with an IC50?value of 64-125?μg/ml. Eleutheroside B1 mediates its anti-influenza activity through POLR2A and N-glycosylation. Eleutheroside B1 inhibits the mRNA expression of several chemokine genes and the influenza nucleoprotein (NP) gene, and exhibits low cytotoxicity. Antiviral and anti-inflammatory activities[1].
 |  | [Biological Activity] 
 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.
