Forsythoside A is a polyphenolic constituent of the fruits of Forsythia suspensa Vahl. which is widely used as an antiinflammatory agent in traditional Chinese medicine. In the present study, the effects of forsythoside A on cell infection by avian infectious bronchitis virus were assessed. A real-time fluorescence quantitative PCR assay was used to determine mRNA content of IBV N gene. The pretreatment of cells with forsythoside A, adding forsythoside A post infection of cells, and treatment of virus with forsythoside A were analysed. The inhibitory effect of forsythoside A was confirmed by infecting primary chicken embryo kidney cells. Infected cells were inhibited by forsythoside A treatment. The data indicated that forsythoside A has the potential to prevent IBV infection in vitro. Copyright © 2010 John Wiley & Sons, Ltd.
连翘酯苷 A 是贯叶连翘果实中的一种多酚类成分,在传统中药中被广泛用作抗炎剂。在本研究中,评估了连翘酯苷 A 对禽传染性支气管炎病毒细胞感染的影响。使用实时荧光定量 PCR 法测定 IBV N 基因的 mRNA 含量。分析了连翘酯苷 A 对细胞的预处理、感染细胞后添加连翘酯苷 A 以及用连翘酯苷 A 处理病毒的效果。通过感染原代鸡胚肾细胞证实了连翘酯苷 A 的抑制作用。连翘酯苷 A 处理可抑制受感染的细胞。数据表明,连翘酯苷 A 具有体外预防 IBV 感染的潜力。版权所有 © 2010 年 John Wiley & Sons, Ltd.
