The Mechanism of Yaotongning Capsule (腰痛宁胶囊) in Treating Lumbar Disc Herniation:based on Network Pharmacology and Molecular Docking
Traditional Chinese medicine (TCM) systematic pharmacology database and analysis platform (TCMSP), TCM comprehensive database (TCMID), Genecards database and DisGeNET database were used to screen out the active ingredients and their target points of
Yaotongning Capsule
through network pharmacology, and LDH-related disease targets were obtained. After drawing Wayne diagram and obtaining the potential targets of
Yaotongning Capsule
for LDH, the protein-protein interaction (PPI) network of
Yaotongning Capsule
for LDH was constructed using STRING 11.5 platform, and the main functional sub-clusters and their core targets were identified by Cytoscape 3.7.2 software. Gene ontology(GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment analysis were performed for core targets based on the annotated database of biological information (DAVID) and the KEGG, while the “drug-ingredient-target” network of
Yaotongning Capsule
for LDH treatment was constructed by Cytoscape 3.7.2 software, and molecular docking verification was carried out by Autodock 4 and Pymol software.
Results
2
A total of 537 active ingredients of
Yaotongning Capsule
, 1335 target points of action and 812 target points of LDH-related diseases were screened out, and 155 potential targets were obtained by drawing Wayne diagram and taking the intersection. After constructing PPI network, five main functional sub-clusters were identified, including 43 core targets. GO enrichment analysis showed that the core targets were involved with 346 biological processes, 30 cell components and 65 molecular functions. KEGG enrichment analysis showed that the core targets were involved with a total of 252 pathways, and were closely realted to PI3K-Akt signaling pathway. The “drug-ingredient-target” network showed that
Yaotongning Capsule
contained 129 active ingredients directly related to LDH treatment. Molecular docking verification showed that the binding energy of key targets interleukin-8 (IL8), matrix metalloproteinase-1 (MMP1) and matrix metalloproteinase-9 (MMP9) with active ingredients wogonin, luteolin, kaempferol and quercetin ≤-5 kcal/mol, which showed good binding ability.
Conclusion
2
Yaotongning Capsule
may treat LDH through the combination of wogonin, luteolin, kaempferol and quercetin with IL8, MMP1 and MMP9 targets, which can inhibit PI3K-Akt signaling pathway and thereby lowering the mechanical pain threshold and relieving neuropathic pain.
