Identification of Licoflavone C as a cap-dependent endonuclease inhibitor against severe fever with thrombocytopenia syndrome virus.
Article in Acta pharmacologica Sinica, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
Severe fever with thrombocytopenia syndrome virus (SFTSV) is a tick-borne virus with a high fatality rate. Currently no approved drugs or vaccines are available against it. Sharing a common replication mechanism with negative-stranded, segmented viruses (NSVs), SFTSV utilizes a cap-dependent endonuclease (CEN) domain of the L segment to execute the cap-snatching process upon genome transcription initiation. Given the crucial role of CEN in the life cycle of NSVs, it is considered a promising target for discovery of antiviral agents against SFTSV. In this study, we established a high-throughput FRET-based enzymatic screening system to discover inhibitors of SFTSV CEN from a chemical library containing 3467 natural compounds. Finally, three compounds, i.e., Licoflavone C, 3,4-dicaffeoylquinic acid, and oleanolic acid displayed exceptional antiviral effects and minimal cytotoxicity. Licoflavone C (EC
