Asprellcosides B attenuates influenza A virus mRNA transcription in MDCK cells. (A,B) The inhibitory effect of Asprellcosides B on the expression of influenza A/FM/1/47(H1N1) HA mRNA and NA mRNA were detected by quantitative real-time PCR at 48 h post-infection. ∗∗p < 0.01, p < 0.05. Assessed the antiviral activity of other influenza virus. (C) The antiviral activity of H1N1 PR8, H9N2, H3N2, and HSV virus were assessed through CPE inhibition by using WST-8 assay, and (D) the antiviral activity of ZIKA and DEVN virus was determined by quantitative real-time PCR. (E) The plaque was fixed and stained at 48 h post infection, and the experimental method was detailed in the Section “Materials and Methods.”
