Objective To explore the potential molecular mechanism of Compound Danshen Dripping Pills in treatment of angina pectoris based on network pharmacology and molecular docking technology. Methods The active ingredients of Compound Danshen Dropping Pills were retrieved through the Traditional Chinese Medicine System Network Pharmacology Database and Analysis Platform (TCMSP), and the angina pectoris-related targets were retrieved using GeneCards, Disgnet and TTD databases. KEGG enrichment analysis and GO enrichment analysis were performed with the intersection targets of angina pectoris. The important signaling pathways and biological processes involved in the anti-angina pectoris of Compound Danshen Dropping Pills were predicted. The Surflex-Dock module of SYBYL2.1 software was used for molecular docking of the screened core components and core targets. Results Total 72 active compounds were screened from Compound Danshen Dropping Pills, involving 500 potential targets. The component targets of Compound Danshen Dropping Pills intersected with the targets of angina pectoris, and 457 intersected targets were obtained. The protein-protein interaction (PPI) network of the target of Compound Danshen Dropping Pills in treatment of angina pectoris contains 158 nodes, of which the important targets are STAT3, TP53, AKT1, JUN, MAPK1, HSP90AA1, etc. Compound Danshen Dropping Pills played a role in treatment of angina pectoris by regulating GO biological processes such as inflammatory response, apoptosis signal pathway and actively regulating cell migration, and participating in fluid shear stress and atherosclerosis, PI3K-Akt signal pathway, MAPK signal pathway, HIF-1 signal pathway, TNF signal pathway and IL17 signal pathway. The results of molecular docking showed that the screened active components had strong binding with the target. Conclusion The potential molecular mechanism and target of Compound Danshen Dropping Pills in treatment of angina pectoris were speculated by using the method of network pharmacology. The molecular docking verified that the selected key active ingredients had strong binding activity with important targets.
