[Analysis of potential pharmacodynamic material basis of Euonymus alatus in treatment of nephritis based on integrated chemomics and network biology].

This paper was aimed to explore the potential pharmacodynamics effect of Euonymus alatus in the treatment of nephritis based on integrated chemomics and network biology. The chemical constituent database of E. alatus was constructed by consulting litera-ture and using online database. The chemical constituents were identified by UPLC-Q-TOF/HRMS~E and UNIFI software. On this basis, a series of comparisons, molecular docking studies and in-depth analysis of the chemical constituents and nephritis disease targets were carried out with use of network biology method, and the potential pharmacodynamic effect of E. alatus for the treatment of nephritis was investigated by reviewing the existing. In this study, 62 chemical constituents were collected in the database of chemical consti-tuents of E. alatus, and 24 chemical constituents were identified by mass spectrum. Subsequently, based on the network biology me-thod, 22 important chemical constituents and 5 key targets were obtained by reverse screening. Molecular docking study showed that a total of 11 chemical constituents such as quercetin, kaempferol, and catechinmay be the potential material basis for E. alatus in the treatment of nephritis. Starting with chemomics and using the technology of network biology, we established a network interaction model between drug components and disease targets in this study. Through the interaction between targets in complex networks, we can find the key targets easily and quickly. By docking the key targets with small drug molecules, we can screen out the potential pharmacodynamic components, providing a reference for the follow-up study of active ingredients.

Research progress on chemical composition and pharmacological effects of Periplocae Cortex and predictive analysis on Q-marker / 中国中药杂志

Periplocae Cortex is a traditional Chinese medicine in China, which is mainly produced in northeast China, north China, northwest China, southwest China. In recent years, the increasing in-depth research resulted in the discovery of anti-tumor and cardiac pharmacological activities of Periplocae Cortex, which has broad application prospects. On the basis of summarizing chemical components and pharmacological effects, combined with the theoretical system of Q-marker, the quality control components of Periplocae Cortex were predicted from the aspects of the correlation between chemical composition and traditional medicinal properties, traditional efficacy, and new clinical use, plasma composition, measurable composition, storage time by analyzing literature. Among the components, periplocoside, periplocin, periplogenin, 4-methoxy salicylaldehyde showed significant activity, which provides a scientific basis for quality evaluation of Periplocae Cortex.
