Anticonvulsant Potential and Network Pharmacology Analysis of Pimenta dioica (L.) Merr.

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
The present study evaluated the anticonvulsant property of hydro-alcoholic leaf extract of Pimenta dioica (L.) Merr. (Allspice), a plant known for its diverse biological properties. Phytochemical screening and ATR-IR spectral analysis confirmed the presence of various metabolites, including flavonoids, tannins, phenolic compounds, and carbohydrates. The acute toxicity study revealed no toxic effects and/or mortality at 2000 mg/kg, suggesting a favorable safety profile of the extract. The extract was administered orally, followed by evaluation in maximal electroshock (MES) and Pentylenetetrazole (PTZ)-induced seizure models. A significant anticonvulsant effect was observed, with 83.3% protection in MES model and notably increasing latency to seizure onset in the PTZ-induced convulsions. GC-MS profiling identified 275 phytocompounds, of which 66 were selected for network pharmacological analysis. This revealed 717 overlapping targets between the selected compounds and epilepsy-related targets. Network pharmacological study suggested AKT1 as a hub gene, and the anticonvulsant effects may be mediated through multiple molecular interactions. Molecular interaction study further supported that the constituents, particularly furaneol, may modulate AKT1 activity through key residue interactions, as observed with the co-crystallized ligand. Overall, the findings support the potential of P. dioica leaf in convulsion, and further work is warranted to explore the active chemicals responsible for the observed activity.
