Abstract

Abstract:

To study the mechanism of Guishaozhenxian Tablet in the treatment of temporal lobe epilepsy (TLE) based on network pharmacology. Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform was used to retrieve the active ingredients and action targets of Guishaozhenxian Tablet, and the standard gene was transformed using the UniProt database. The OMIM, GeneCards, and DrugBank databases were searched for disease targets related to TLE, and the intersection targets of Guishaozhenxian Tablet in the treatment of TLE were obtained using a Venn diagram. The medicinal herb-component-target network diagram was constructed using the Cytoscape 3.8.2 software, and the core components and key molecular targets were analyzed.Gene Ontology enrichment and the Kyoto encyclopedia of genes and genomes were used to analyze the biological processes and related pathways. The first three key targets and their corresponding top two core compounds were validated using molecular docking. In total, 127 active ingredients and 46 related targets were identified, with 14 ingredients, including β-sitosterol, quercetin, and kaempferol, playing a central role in 11 key targets such as CALM1, SCN5A, and GSK3B. The anti-TLE effect was primarily due to biological processes (regulation of membrane potential, response to drug, etc.), cell components (postsynaptic membrane, dendrites, etc.), molecular functions (channel activity, calmodulin binding, etc.), neuroactive ligand-receptor interaction, nicotine addiction, and other related pathways. Molecular docking results showed that CALM1, SCN5A, and GSK3B had good binding abilities with core compounds. Guishaozhenxian Tablet can reduce oxidative damage; protect neurons; affect ion channels and receptors, intracellular signal transduction, apoptosis, and synaptic structure; and exert anti-TLE effects via multi-components, multi-targets, and multi-pathway coordination.

Key words: network pharmacology, molecular docking, Guishaozhenxian Tablet, temporal lobe epilepsy, mechanism of action
