Discovery of bioactive inhibitors targeting onion yellow dwarf virus coat protein based on molecular docking and simulation.
Article in BMC plant biology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundOnion yellow dwarf virus (OYDV), a devastating pathogen affecting garlic (Allium sativum), causes significant agricultural losses worldwide. Current management strategies rely on chemical pesticides that pose environmental and toxicity concerns, hence emphasizing the urgent need for eco-friendly alternatives.
resultsThis study aimed to discover plant-derived inhibitors of OYDV by targeting its coat protein through several computational approaches. The CP of OYDV was characterized, and a high-quality 3D model was validated. Through high-throughput molecular docking of 46 plant-based metabolites, four compounds were selected: hypericin, celastrol, sanguinarine, and asiatic acid with superior binding affinities (below - 9 kcal/mol). These four had exceptionally high docking scores, outperforming the commercial antivirals ribavirin and ningnanmycin. These top ligands have been proven to be less hazardous via in silico toxicity profiling, which makes them suitable for the development of biopesticides. DFT analysis and MD simulations validated the stability and structural flexibility of the hypericin and coat protein, respectively.
conclusionThese computational findings suggest hypericin could be a promising lead compound for developing sustainable OYDV management strategies.
