Neurotherapeutic effects of Vutiglabridin as a Paraoxonase-2 modulator in preclinical models of Parkinson's disease.
Article in Molecular neurodegeneration, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 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
backgroundParkinson's disease (PD) is the second most prevalent neurodegenerative disease characterized by motor impairment resulting from the degeneration of dopaminergic neurons in the substantia nigra, alongside α -synuclein (α-syn) accumulation, mitochondrial dysfunction, and oxidative stress. Recent studies on PD treatment have focused primarily on exploring oxidative stress and mitochondrial function as ways to restore dopamine release. Notably, previous studies have demonstrated that Paraoxonase 2 (PON2) plays a critical role in neuroprotection and neuroinflammation by reducing oxidative stress in striatal neurons and astrocytes.
methodsIn this study, we investigated the potential therapeutic effect of a newly developed drug, Vutiglabridin, which is demonstrated to augment the activity of PON2 in the mouse model of PD. We assessed the impact of Vutiglabridin in a PD model induced by MPP
resultVutiglabridin effectively crosses the blood-brain barrier (BBB) and maintains a presence in the brain for over 24 h, achieving concentrations up to 2.5 times higher than in the bloodstream. It successfully binds to PON2 in both its (R) and (S) forms. Vutiglabridin reversed mitochondrial dysfunction, reduced oxidative stress, improved motor functions, and protected dopaminergic neurons against MPP+-induced damage. Similarly, in α-syn A53T overexpressed PD models, it not only reduced astrocytic reactivity and microglia activation but also doubled the tyrosine hydroxylase positive neurons /dopa decarboxylase positive neurons (TH+/DDC+) ratio, signifying enhanced neuronal health. However, these positive outcomes were absent in PON2-knockdown mice, underscoring Vutiglabridin's reliance on PON2 for its neuroprotective effects.
conclusionThese findings indicate that Vutiglabridin may serve as a promising therapeutic approach for reducing reactive oxygen species (ROS) levels by modulating PON2 activity in Parkinson's diseases.
