Molecular mechanism of Shuguan Granules in treating angina based on integrative pharmacology

Abstract

The paper analyzed the combined administration of traditional Chinese medicine Shuguan Granules, and studied its six plant herbs, namely Polygoni Multiflori Radix, Salviae Miltiorrhizae Radix et Rhizoma, Polygonati Rhizoma, Chuanxiong Rhizoma, Epomedii Folium, and Carthami Flos by network pharmacology analysis, in order to define chemical constituents and drugs targets through integrated pharmacology platform. Based on the results, indications of Shuguan Granules were collected through the ETCM database. Therefore, the present study could determine the potential optimal indications of the drug. The results showed that chest apoplexy was the main traditional Chinese medicine(TCM) symptom treated by Shuguan Granules, whose monarch drug was Salviae Miltiorrhizae Radix et Rhizoma. Network pharmacology analysis found that the target enrichment results of Shuguan Granules were related to the indications of coronary heart disease, angina and atherosclerosis. According to the indications, angina may be the best indication for Shuguan Granules. The 229 components in Shuguan Granules involved a total of 109 core targets, of which TNF and MMP9 were the direct targets to the angina disease. In addition, Shuguan Granules could also indirectly intervene in the progression of angina through MAPK, NFKB, GF and other targets. The main pathways involving angina pectoris are PI3 K-Akt signaling pathway, RAS signaling pathway, TNF signaling pathway, Estrogen signaling pathway and glycolysis/gluconeogenesis, which can intervene in many aspects of angina, such as inflammatory reaction, blood lipid metabolism and vasodilation.
