Background and objective: Li Chong Wan (Li Chong pill, LCP) origin from Yi Xue Zhong Zhong Can Xi Lu, (Records of Chinese Medicine with Reference to Western Medicine), widely used in the treatment of endometriosis (EM) in China. The purpose of this study is to investigate the intrinsic mechanisms of LCP against EM and to provide new evidence for its clinical application.
Methods: Chemical compounds of LCP were screened and evaluated via retrieving public databases and literature. We also acquired their putative targets and obtained EM-related targets. The above-mentioned data were visualized as a component-target network. In addition, we use Cytoscape3.8.0 to build a protein-protein interaction network and identified hub genes and key active ingredients. Furthermore, through GO and KEGG pathway analyses, which were actualized by R3.6.1 (based on clusterProfiler, org.Hs.eg.Db, and pathview package), we obtained effective signaling pathways and biological functions. Molecular docking was used to verify binding activity between compounds and the key targets at last.
Results: Finally, a total of 122 possible active targets and 47 components were screened. Identify the core network and screen out 10 main targets; GO and KEGG enrichment analysis revealed that LCP may have functions of anti-inflammatory, anti-angiogenesis, inhibition of cell proliferation, regulation of hormone secretion, etc. The effect of LCP on EM might be achieved by PI3K/Akt signaling pathway, HIF-1 signaling pathway, estrogen signaling pathway, and VEGF signaling pathway, etc. Finally, molecular docking results demonstrated that 14 components were exhibited good binding property to the key targets of EM.
Conclusion: This research ocularly demonstrated the multi-component, multi-target, and multi-channel pharmacological effects for LCP in the treatments of EM and provides evidence for further clinical research and verification of the mechanism.
