- Abstract
As a classic prescription, Wuji Pills is composed of Coptidis Rhizoma, Euodiae Fructus Preparata, and stir-fried Paeo-niae Radix Alba at the ratio of 6∶1∶6. The practical application of it is limited compared with other famous Chinese medicine prescriptions. Only one company produces Wuji Pills in China. In this study, ultra-performance liquid chromatography quadrupole time of flight mass spectrometry(UPLC-Q-TOF-MS/MS) was used to analyze and identify 26 identical compounds from Wuji Pills and drug-containing plasma of rats. Based on these components, 46 potential targets were screened out with network pharmacology methods, followed by the component-target network construction, Gene Ontology(GO) term enrichment, Kyoto Encyclopedia of Genes and Genomes(KEGG) pathway enrichment, and disease prediction. It was concluded that Wuji Pills acted on core targets such as PTGS2, PTSG1, NCOA2, HSP9 OAD1, and RXRA through magnoflorine, hydroxyevodiamine, daucosterol, and berberine and exerted pharmacodynamic effects through various pathways such as calcium ion signaling pathway, phosphatidylinositol-3-kinase-protein kinase B(PI3 K-Akt) signaling pathway, and vascular endothelial growth factor(VEGF) signaling pathway. Thus, Wuji Pills has therapeutic potential for Alzheimer's disease, diabetes mellitus, myocardial ischemia, and other diseases in addition to the conventional disease(irritable bowel syndrome, IBS). The above research results can provide a reference for the comprehensive interpretation of the pharmacodynamic basis of Wuji Pills and the expansion of clinical application. At the same time, a lot of components in serum and the in vivo transformed and metabolized components of Wuji Pills have similar structure and relative molecular weight. In theory, these components may show additive effects and the competitive/antagonistic effects on the same target. According to the hypothesis ofquot;additive effect of multiple components for a single targetquot; in traditional Chinese medicine, multiple similar components may exert the additive effects on local targets. This study can partly prove the scientificity of this hypothesis and provide laboratory evidence.
