Fig. 6 in Undescribed phloroglucinol derivatives with antiviral activities from Dryopteris atrata (Wall. Ex Kunze) Ching
Fig. 6. Antivirus activity of compound 7 against HSV-1 by using a fluorescence assay. Compound 7 was added at 20 μM at different times post-infection (1, 2, 4, 6, 8, 12, and 20 h), and acyclovir was used as the positive control. Data were expressed as mean ± SD from three independent experiments (***p <0.001 compared with the viral control group).
