Structural and mechanistic profiling of Nurr1 modulation by vidofludimus enables structure-guided ligand design.
Article in Communications chemistry, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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 neuroprotective transcription factor nuclear receptor related 1 (Nurr1, NR4A2) is in the focus of biomedical research for its promising neuroprotective role in Parkinson's disease, Alzheimer's disease, and multiple sclerosis. Its activity can be controlled by ligands offering access to pharmacological Nurr1 modulation. However, the binding epitope(s) and molecular activation mechanisms of synthetic Nurr1 activators remained elusive but are essential to advance Nurr1 ligands towards new medicines. Here we characterized Nurr1 dimer dissociation and coregulator release as molecular contributions to Nurr1 activation by vidofludimus and locate its binding in an allosteric surface pocket lined by helices 1, 5, 7, and 8 by mutagenesis and molecular dynamics simulation. Structure-guided ligand design using these insights resulted in an optimized Nurr1 agonist with substantially enhanced potency and binding affinity. Our results provide a structural and molecular basis for Nurr1 activation by a synthetic agonist which was lacking for rational ligand design.
