Investigation of active components and mechanism of Pudilan Xiaoyan Oral Liquid based on network pharmacology

Abstract

To investigate the active components/ingredients of Pudilan Xiaoyan Oral Liquid based on the network pharmacology technology, and analyze the network data of its potential targets and mechanisms. The active ingredient screening, protein interaction analysis and pathway annotation were used to further optimize its active components and potential targets, and clarify the pharmacodynamic substance basis and mechanism of Pudilan Xiaoyan Oral Liquid. Through this technique, we screened out 41 active ingredients in Pudilan Xiaoyan Oral Liquid, mainly including 16 alkaloid components, 13 organic acid components, 11 flavonoid components and 1 coumarin component such as chicoric acid, chlorogenic acid, oroxindin, rutin, corynoline, and esculetin. In addition, 6 targets for parotitis, 48 targets for tonsillitis, and 22 targets for pharyngitis were screened. A total of 22 disease signaling pathways are involved, including 4 pathways closely related to inflammation. The IL-17 signaling pathway had the highest D(degree) value and may be most closely related to inflammatory diseases. Through network data excavating, we initially explored the main active components/ingredients of Pudilan Xiaoyan Oral Liquid, clarified the pharmacodynamic basis of Pudilan Xiaoyan Oral Liquid treatment-related diseases and its key mechanism of action in this study, hoping to provide a theoretical basis for clinical research, and at the same time, lay the foundation for deep research and promotion of Pudilan Xiaoyan Oral Liquid product.
