摘要

Background: Radiation-induced oral mucositis (RIOM) is an intractable inflammatory disease whose pathogenesis needs to be clarified. “Kouchuangling” (KCL), a traditional Chinese medicine formula, is composed of Lonicerae Japonicae Flos, Radix Paeoniae Rubra, and Radix Sanguisorbae. Although all of them are Chinese folk medicines which have long been utilized for ameliorating inflammation, the mechanism of KCL to RIOM remains unclear. Purpose: To predict the active ingredients of KCL and identify the mechanism of KCL on RIOM. Materials and Methods: We identified the chemical ingredients in KCL using TCM Systems Pharmacology (TCMSP), TCM@Taiwan, PubChem, and SuperPred databases and used the oral bioavailability (OB), drug-like properties (DL) and Degree of compounds for screening. Targets for oral mucositis were obtained from the Online Mendelian Inheritance in Man (OMIM), Therapeutic Target Database (TTD), PharmGKB, and DrugBank databases. Cytoscape 3.7.0 was used to visualize the compound-target-disease network for KCL and RIOM. The biological processes of target gene ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathways were analyzed using DAVID. Results: Based on OB≥30, DL≥0.18 and Degree≥3, 24 active ingredients and 960 targets on which the active components acted were identified. A total of 1387 targets for oral mucositis were screened. GO enrichment and KEGG pathway analyses resulted in 43 biological processes (BPs), 3 cell components (CCs), 5 molecular functions (MFs), and 32 KEGG pathways, including leishmaniasis, Toll-like receptor signaling, TNF signaling, and Influenza A pathways. Conclusion: This experiment preliminarily verified that the active ingredients of KCL play a role in the treatment of RIOM through multiple targets and pathways, providing a reference for further study of the pharmacological mechanism of Chinese herbal medicine.
