1 · What the graph read from it

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.

2 · The registry

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

The World Health Organization (WHO) has declared the monkeypox outbreak a public health emergency, as there is no specific therapeutics for monkeypox virus (MPXV) disease. This study focused on docking various commercial drugs and plant-derived compounds against the E8 envelope protein crucial for MPXV attachment and pathogenesis. The target protein structure was modeled based on the vaccinia virus D8L protein. Notably, maraviroc and punicalagin emerged as potential ligands, with punicalagin exhibiting higher binding affinity (- 9.1 kcal/mol) than maraviroc (- 7.8 kcal/mol). Validation through 100 ns molecular dynamics (MD) simulations demonstrated increased stability of the E8-punicalagin complex, with lower RMSD, RMSF, and Rg compared to maraviroc. Enhanced hydrogen bonding, lower solvent accessibility, and compact motions also attributed to higher binding affinity and stability of the complex. MM-PBSA calculations revealed van der Waals, electrostatic, and non-polar solvation as principal stabilizing energies. The binding energy decomposition per residue favored stable interactions between punicalagin and the protein's active site residues (Arg20, Phe56, Glu228, Tyr232) compared to maraviroc. Overall study suggests that punicalagin can act as a potent inhibitor against MPXV. Further research and experimental investigations are warranted to validate its efficacy and safety.
