title: Antiviral activities of diarylheptanoids against influenza virus in vitro.
abstract: The anti-influenza A/PR/8/34 (H1N1) virus activities of ten diarylheptanoids isolated from Alpinia officinarum were examined using the MTT method. The 50% inhibitory concentration of each diarylheptanoid examined was clearly lower than its 50% cytotoxic concentration determined by the MTT assay and/or maximum non-cytotoxic concentration (MNCC) determined by the morphological change of cells. In particular, the influenza virus was more susceptible to 7-(4''-hydroxy-3''-methoxyphenyl)-1-phenyl-4E-hepten-3-one (3) and (5S)-5-hydroxy-7-(4''-hydroxyphenyl)-1-phenyl-3-heptanone (8) than the other diarylheptanoids. Thus, all diarylheptanoids exhibited potential antiviral activity against influenza virus in vitro.
