Antiviral Effect of Amentoflavone Against Influenza Viruses.
Article in International journal of molecular sciences, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Amentoflavone (AF) is a biflavonoid compound found in many plants. In this study, we first demonstrate that AF has a potent antiviral effect against the influenza virus via the inhibition of viral attachment and virucidal effects. The anti-influenza-viral effect of AF was evaluated using green fluorescent protein-tagged Influenza A virus (IAV) with fluorescent microscopy and flow cytometry analysis. AF decreased the GFP expression by viral infection, dose-dependently. Fifty micromoles of AF suppressed the GFP expression by virus infection of up to 70% of untreated infected control cells. Consistently, immunofluorescence results showed the inhibitory effect of AF on viral protein expression. Time-of-addition and hemagglutination assays revealed that AF inhibits viral binding to cells by interfering with the hemagglutinin (HA) of IAV. Furthermore, AF has a virucidal effect and blocks cytopathic effects caused by the Influenza B virus and H3N2 IAV. Additionally, AF represses the neuraminidase (NA) activity of IAV. In silico analysis confirmed the potential interaction of AF with both HA and NA. Our findings indicate that AF has antiviral effects by modulating HA and NA during the attachment and release stages of influenza viral infection.
