Stroke remains a leading cause of mortality and disability worldwide, with limited treatment options highlighting the need for alternative therapies. Mitochondrial autophagy plays a crucial role in stroke pathology, presenting a potential therapeutic target. Gypenoside XLIX demonstrated mitochondrial protective effects. However, its efficacy in preventing mitochondrial damage in neuronal cells remained unclear. Therefore, this study investigated the role and mechanism of Gypenoside XLIX in alleviating ischemic stroke injury. We evaluated the neuroprotective effects of Gypenoside XLIX using cellular oxygen-glucose deprivation (OGD) and middle cerebral artery occlusion (MCAO) rat models. The bioinformatic analyses revealed that Gypenoside XLIX interacts with the PI3K-Akt signaling pathway. In OGD cells, Gypenoside XLIX facilitated autophagic flux and reduces apoptosis and reactive oxygen species (ROS) levels. Additionally, Gypenoside XLIX upregulated p-PI3K and p-AKT while downregulating FOXO1 protein expression. In MCAO rats, Gypenoside XLIX markedly decreased the infarct size, brain edema rate, and cell apoptosis, while enhancing mitochondrial membrane potential, oxidative stress indicators (SOD, GSH-Px, and CAT), and autophagic flux. These results suggest that Gypenoside XLIX might alleviate ischemic stroke injury by activating the PI3K/AKT/FOXO1 pathway, which in turn promotes mitochondrial autophagy and reduces neuronal apoptosis.
