摘要

AD, a progressive neurodegenerative disorder, imposes an increasingly heavy burden on global public health, with its pathogenesis remaining incompletely understood. Meanwhile, EDCs—widely present in the environment, food, and consumer products—have emerged as a significant public health concern due to their diverse health risks, including potential contributions to neurodegenerative processes such as AD by disrupting neurohomeostasis. Furthermore, as natural compounds, ginsenosides and other AS have been the focus of numerous studies exploring their role in treating AD, thanks to their advantages of multi-target properties and low side effects. However, the specific molecular pathways through which EDCs induce AD, as well as the mechanisms by which AS may counteract EDC-induced toxicity and intervene in AD, remain unclear. Against this background, this study sought to: (1) explore the molecular pathways through which EDCs may induce AD by disrupting neurohomeostasis; (2) preliminarily investigate the potential of AS in treating AD and antagonizing EDC-induced AD at the molecular level. To achieve these goals, we integrated network toxicology, network pharmacology, and molecular docking to construct a multi-dimensional interaction network among EDCs, AD, and AS. By establishing intersecting target sets for EDCs-AD and AS-AD, core targets were identified via topology analysis of protein-protein interaction (PPI) networks. GO and KEGG enrichment analyses highlighted key pathways, including serotonergic synapse and neuroactive ligand-receptor interaction. Molecular docking further explored interactions between EDCs/AS and core target proteins. The results suggest that EDCs may drive neurodegeneration in AD by impairing synaptic function, while AS may counteract these effects by enhancing synaptic activity, stabilizing membrane microenvironments, inhibiting Aβ aggregation, alleviating neuroinflammation, and restoring metabolic homeostasis. Further analysis indicated that AS exhibit stronger binding ability to core targets compared to EDCs, implying a potential antagonistic effect of AS against EDCs. This study provides insights into the molecular mechanisms underlying EDC-induced AD and establishes a multi-target theoretical framework for AS-mediated antagonism of EDC toxicity, offering a reference for the prevention and treatment of neurodegenerative diseases.
