Exploring the mechanism of Shenqisherong pill against cervical spondylotic myelopathy by network pharmacology and molecular docking.

Background Shenqisherong pill (SQSRP) has been used clinically to treat cervical spondylotic myelopathy (CSM) with satisfactory results; however, its active ingredients and mechanisms are unclear. The present study aimed to explore the active ingredients and molecular mechanisms of SQSRP against CSM using network pharmacology and molecular docking. Methods The compounds in SQSRP were obtained from public databases and related literature, and oral bioavailability (≥30%) and drug-likeness (≥0.18) were screened using absorption, distribution, metabolism, and excretion (ADME) criteria. Compounds-related and CSM-related target genes were identified using public databases, and the overlapping genes between compounds and CSM target genes were identified using a Venn diagram. Cytoscape and STRING were used to construct, visualize, and analyze the interaction network between these overlapping targets. Gene Ontology (GO) and KEGG pathway enrichment analysis of overlapping targets used Omicshare tools and constructed a compound-overlapping targets network, target-pathway network, and compound-target-pathway network using Cytoscape. Finally, molecular docking software was used to verify the targets. Results A total of 447 compounds in SQSRP were identified, and ADME screening identified 96 compounds as potentially active ingredients. A total of 249 compound-related genes and 280 CSMrelated genes were identified using public databases, and 53 overlapping genes were identified. The results of compound targets and protein-protein interaction network analysis showed that the pharmacological effects of SQSRP against CSM involved 56 compounds and 53 genes. The results of GO and KEGG pathway enrichment analysis suggested that the therapeutic effects of SQSRP against CSM were exerted by reducing inflammation, inhibiting apoptosis, and protecting neurons. The molecular mechanisms may be strongly associated with PI3K-Akt, MAPK, IL-17, and TNF, which might be pivotal signaling pathways. Conclusions The active ingredients and mechanisms of SQSRP against CSM were investigated using network pharmacology. The findings proved that the pill could treat CSM through multi-component, multitarget, and multi-pathway synergy and provide a theoretical basis for the subsequent extraction of active ingredients from SQSRP.
