Alchemilla Vulgaris Compounds as Inhibitors of HPV 16 E6 Oncoprotein: Quercetin with Promising in Silico Potential.
Article in Materia socio-medica, 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
Background: The oncogenic potential of HPV remains a major global public health challenge and various natural therapeutics are being investigated to prevent cancer. The natural components of the Alchemilla vulgaris plant have various anti-inflammatory, antioxidant, antiviral, and anticancer effects. Objective: Therefore, the aim of this study was to bioinformatically examine the potential inhibitory effect of A. vulgaris compounds on the HPV target protein. Methods: The structures of quercetin, catechin, apigenin, luteolin, caffeic and gallic acid were taken from the PubChem database, and the protein structure of the target HPV 16 E6 oncoprotein (PDB ID: 4XR8) from the Protein Data Bank. Virtual screening and docking analysis were performed in AutoDock Vina. Protein-ligand complexes were visualized using Discovery Studio. The molecular dynamics simulation of 4XR8 in complex with quercetin was performed using Desmond. Results: Docking analysis showed that quercetin has the strongest binding affinity with 4XR8 (quercetin -8.9 kcal/mol, apigenin -8.7 kcal/mol, luteolin -8.7 kcal/mol, catechin -8.4 kcal/mol, caffeic acid -7.3 kcal/mol, gallic acid -6.8 kcal/mol). The molecular dynamics simulation results reinforce the stability and strong binding affinity of quercetin within the HPV 16 E6 oncoprotein. Conclusion: Natural components of Alchemilla vulgaris, especially quercetin, have shown promising potential for the treatment of HPV infection and additional in vitro and in vivo studies are needed for their further research.
