Comparison of Anti-insomnia Mechanism Between Ziziphi Spinosae Semen and Ziziphi Spinosae Fructus Based on Network Pharmacology

Objective To compare the material basis and mechanism of Ziziphi Spinosae Semen and Ziziphi Spinosae Fructus in the treatment of insomnia based on network pharmacology.Methods The active components and targets of Ziziphi Spinosae Semen and Ziziphi Spinosae Fructus were screened from Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform (TCMSP), Bioinformatics Analysis Tool for Molecular mechanism of Traditional Chinese Medicine (BATMAN-TCM), and Encyclopedia of Traditional Chinese Medicine (ETCM) and relevant literature. The targets of insomnia were screened from GeneCards and NCBI database. The targets of active ingredients and insomnia were intersected to obtain the common targets. DAVID 6.8 was employed to conduct the gene ontology (GO) annotation and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment of the common target for predicting the mechanism of action. Cytoscape 3.8.0 was used to construct the "Chinese herbal medicine-component-target-pathway" network, and topological analysis of the network was then performed to identify the core components and core targets of Ziziphi Spinosae Semen and Ziziphi Spinosae Fructus for treating insomnia. Finally, molecular docking was carried out to verify the predicted mechanism.Results We screened out 17 active components and 579 targets of Ziziphi Spinosae Semen, 15 active components and 410 targets of Ziziphi Spinosae Fructus, and 2563 targets of insomnia. Insomnia shared 151 and 116 common targets with Ziziphi Spinosae Semen and Ziziphi Spinosae Fructus, respectively. Both Ziziphi Spinosae Semen and Ziziphi Spinosae Fructus can act on tumor necrosis factor (TNF) signaling pathway, dopaminergic synapse, serotonergic synapse, GABAergic synapse, and nuclear factor-kappa B signaling pathway via core components (e.g., quercetin and palmitic acid) and core targets [e.g., phosphoinositide-3-kinase (PIK3CG), TNF, and protein kinase B1 (Akt1)]. Molecular docking showcased that the active components had strong binding ability to targets.Conclusion This study preliminarily predicted and compared the mechanism of Ziziphi Spinosae Semen and Ziziphi Spinosae Fructus in the treatment of insomnia. The two medicinal materials have 7 common active components and 357 common targets and employ similar biological processes and signal pathways for treating insomnia. The findings indicate that Ziziphi Spinosae Semen and Ziziphi Spinosae Fructus have certain similarities in the treatment of insomnia, which provides a research basis for the comprehensive utilization of wild jujube resources.
