Influenza virus is one of the most widespread infectious diseases in the world. It poses a serious public health threat to humans. With the emergence of drug-resistant virus strains, antiviral drugs are urgently needed to control virus transmission and disease progression. In this study, three main active substances-curcumol, curdione and germacrone-were isolated from the traditional Chinese medicine zedoary. They inhibited the replication of influenza A (H1N1) virus in a dose-dependent manner. After treatment with these compounds, the expression of viral protein and RNA synthesis were inhibited. In vivo, these compounds also reduced H1N1-induced lung damage and the load of virus in serum as well as whole blood cells. In a proteomic analysis, after treatment with germacrone, the expression of antiviral protein and the amount of intracellular virus were significantly reduced, further proving that germacrone can inhibit viral replication. Our experiments have shown that curcumol, curdione and germacrone can inhibit the replication of H1N1 virus; in particular, germacrone shows potential both in vitro and in vivo as a therapeutic drug.
