Ischemic stroke is an acute cerebrovascular disease with high disability and morbidity. However, therapeutic approaches are restricted by a narrow time window for reperfusion. Astilbin has various pharmacological activities and good therapeutic potential against ischemic stroke and neurodegenerative diseases. Nevertheless, Astilbin’s mechanism of action remains unclear. Here, we used an integrated strategy that includes network pharmacology, omics validation, and functional verification. Potential targets of Astilbin were predicted using SwissTargetPrediction and PharmMapper, and cross-analyzed with IS-related genes from multiple databases. GO/KEGG enrichment analyses showed that Astilbin synergistically regulates stroke-associated pathways (e.g., MAPK, AGE-RAGE). Combined transcriptomic and metabolomic assays confirmed that Astilbin ameliorates OGD/R-induced oxidative stress and metabolic disorders by modulating the MAPK and ferroptosis pathways. Molecular docking and dynamics simulations revealed that Astilbin has high affinity for core targets (ERK1/2, CREB, p90RSK, MMP9) and binds stably to MMP9. Using an OGD/R-injured neuronal-like PC12 cell line, in vitro assays confirmed that Astilbin alleviates oxidative stress, calcium overload, lipid peroxidation, and intracellular iron levels, while also modulating apoptosis- and inflammation-related genes. Overall, this study has established a comprehensive pharmacological framework for the use of Astilbin against IS, clarified its multi-target, multi-pathway neuroprotective mechanisms of action, and provided evidence for its potential in the treatment of IS.
