| Summary: | PANoptosis is a newly identified form of cell death that encompasses pyroptosis, apoptosis, and necroptosis. Numerous studies have highlighted the significance of PANoptosis in brain ischemia–reperfusion (I/R) injury. Calycosin, a natural product with diverse biological activities, has demonstrated a significant reduction in neuronal death caused by ischemic brain injury by modulating multiple cell death pathways. In order to investigate the potential mechanisms underlying the neuroprotective role of calycosin in alleviating PANoptosis-induced damage in ischemic stroke therapy, we used mouse hippocampal neuronal cell line HT22 to stimulate ischemia in vitro through Oxygen and Glucose Deprivation/Reperfusion (OGD/R) and established molecular docking to assess the binding affinity of Calycosin with key targets and molecular dynamics simulations (MDS) to study the stability of the ligand–protein complex. The results demonstrate that Calycosin could improve the cell growth of HT22, leading to enhanced cell viability, reduced lactate dehydrogenase leakage, and decreased cell apoptosis after OGD/R. It also regulated the expression of PANoptosis-related genes such as NLRP3, GSDMD, MLKL, and RIPK1 and increased the Bcl-2/Bax ratio, effectively reducing cellular damage and providing protection. Molecular docking and MDS simulations demonstrated strong binding activity and stability between Calycosin and PANoptosis-related targets. Furthermore, Calycosin successfully passed the drug similarity (DS) evaluation and exhibited favorable absorption, distribution, metabolism, excretion, and toxicity (ADMET) properties and biological activity. In conclusion, Calycosin could alleviate ischemic stroke by inhibiting PANoptosis, reducing neuronal inflammation and apoptosis, and improving damage caused by the OGD/R. Thus, it could serve as a potential therapy for ischemic stroke. |
