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.
采用 MTT 法检测了从高良姜中分离得到的 10 种二芳基庚烷类化合物对甲型/PR/8/34(H1N1)流感病毒的抑制活性。各二芳基庚烷类化合物的 50%抑制浓度均明显低于其通过 MTT 测定的 50%细胞毒性浓度和/或通过细胞形态变化确定的最大非细胞毒性浓度(MNCC)。特别是,与其他二芳基庚烷类化合物相比,7-(4''-羟基-3''-甲氧基苯基)-1-苯基-4E-庚烯-3-酮(3)和(5S)-5-羟基-7-(4''-羟基苯基)-1-苯基-3-庚酮(8)对流感病毒的敏感性更高。因此,所有二芳基庚烷类化合物在体外均表现出抗流感病毒的潜在活性。
