Abstract: To predict the active components and key targets of Cinnamomi Cortex in the treatment of diabetes and analyze its mechanisms using bioinformatics technology and network pharmacology. The effective compounds and the corresponding target proteins of Cinnamomi Cortex were determined and screened using the Traditional Chinese Medicine System Pharmacology Database and Analysis Platform(TCMSP) database and a literature search. Diabetes-related genes were obtained from the GeneCards Database, and the compound-target network and the protein-protein interaction (PPI) network were constructed. Gene ontology(GO) and Kyoto Encyclopedia of Genes and Genomes(KEGG) analysis were conducted using the Database for Annotation, Visualization and Integrated Discovery(DAVID) and STRING databases. Molecular docking was performed between active components and key targets. Overall, 32 active components were found to act on 131 related targets and 20 core genes such as INS, AKT1, IL6, TNF, and VEGFA. GO and KEGG analysis showed that Cinnamomi Cortex was mainly involved in biological processes such as positive regulation of transcription by RNA polymerase II promoter, as well as pathways covering the AGE/RAGE signaling pathway in diabetic complications and IL-17 signaling pathway. The results of molecular docking of 10 key components showed that quercetin and procyanidin B1 in Cinnamomi Cortex had better affinity with INS, IL6, VEGFA, and TNF. This study preliminarily explained the mechanism of Cinnamomi Cortex in in treatment of diabetes, which will be helpful to guide the clinical use of drugs.
