Discovery of a novel Keap1 inhibitor for neurodegeneration through virtual screening and molecular dynamics simulations.

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
Oxidative stress is a key feature of Alzheimer's disease (AD) and other neurodegenerative disorders. The Kelch-like ECH-associated protein 1 (Keap1)-nuclear factor erythroid 2-related factor 2 (Nrf2) pathway controls redox balance, and disrupting the Keap1-Nrf2 protein-protein interaction (PPI) has become a promising therapeutic approach. Marine natural products (MNPs), because of their structural diversity and bioactivity, are an underexplored source of potential neuroprotective compounds. This study aimed to identify novel marine-derived inhibitors of the Keap1-Nrf2 interaction using a comprehensive in silico pipeline. A total of 14,492 compounds from an open-access MNP database were virtually screened against the Keap1 Kelch domain through molecular docking. The top 1,329 candidates exhibited strong binding affinities, with several reaching scores comparable to the co-crystallized reference ligand L5F. Absorption, distribution, metabolism, excretion, and toxicity (ADMET) profiling was employed to assess pharmacokinetic properties, brain penetration, and safety, leading to the identification of compound 145398-61-4 as the most promising hit. Molecular dynamics (MD) simulations verified the structural stability of the Keap1-145398-61-4 complex, while binding free energy calculations indicated energetically favorable interactions. Additional validation using principal component analysis (PCA) and highest occupied molecular orbital-lowest unoccupied molecular orbital (HOMO-LUMO) energy analysis further confirmed the stability of this interaction. Overall, our in silico study identified compound 145398-61-4 as a novel Keap1-Nrf2 inhibitor, highlighting its potential as a lead candidate for developing treatments for Alzheimer's disease and other neurodegenerative disorders, such as amyotrophic lateral sclerosis and multiple sclerosis.
