Application of Free Energy Perturbation (FEP) Methodology for Predicting the Binding Affinity of Macrocyclic JAK2 Inhibitor Analogues of Pacritinib.
Article in ACS medicinal chemistry letters, 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
Pacritinib, an orally bioavailable macrocyclic inhibitor of Janus Kinase 2, has shown efficacy for the treatment of myelofibrosis. Due to the synthetic challenges associated with synthesizing macrocyclic analogues, we applied electrostatic complementarity, 3D-field QSAR, and free energy perturbation methods for the profiling of a set of known ligands with a view to developing a prioritization method for selecting new macrocyclic designs for synthesis. The importance of understanding the 3D conformation and flexibility of a ligand is demonstrated, with these effects having a significant implication on the accuracy of predictions.
