Structural Insight on Interaction of NMDA receptor with fentanyl, ketamine and Isoflurane: A Computational Study to Unravel Mode of Binding.
Article in Cell biochemistry and biophysics, 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
NMDA receptors are considered targets for many anesthetics if they are modulated by the drugs at clinically relevant concentrations. Volatile anesthetics like isoflurane and ketamine interact with NMDA receptors, inhibiting channel activation and thus blocking NMDA neurotransmission at clinically relevant concentrations. The mode of binding of commonly used drugs like ketamine, isoflurane, and fentanyl is poorly understood. We used molecular docking, molecular dynamics simulations, and DFT calculation of these drugs against the NMDA receptor. Using well-defined computational methods, we identified that these drugs have high docking scores and significant interaction with receptors. These drugs bind to the substrate-binding pocket and form a remarkable number of interactions. We have found that these interactions are stable and have low HOMO-LUMO energy gaps. This study provides enough evidences of strong and stable interaction between drugs and NMDA receptor.
