Network pharmacology approach and experimental verification of Dan-Shen Decoction in the treatment of ischemic heart disease.

ABSTRACT

CONTEXT Dan-Shen Decoction, which is composed of Danshen, Tanxiang and Sharen, has a good therapeutic effect on ischemic heart disease (IHD). However, systematic research on the exact mechanism of action of Dan-Shen Decoction is still lacking. The anti-IHD effect of Dan-Shen Decoction was examined in this study using a systematic pharmacological method. OBJECTIVE: This study validates the efficacy and explores the potential mechanisms of Dan-Shen Decoction in treating IHD by integrating network pharmacology analyses and experimental verification. MATERIALS AND METHODS: The active components, critical targets and potential mechanisms of Dan-Shen Decoction against IHD were predicted by network pharmacology and molecule docking. H9c2 cells were pretreated with various 1 µg/mL Dan-Shen Decoction for 2 h before induction with 1000 µmol/L CoCl2 for 24 h. The cell viability was detected by CCK8, and protein expression was detected by western blots. RESULTS: The network pharmacology approach successfully identified 69 active components in Dan-Shen Decoction, and 122 potential targets involved in the treatment of IHD. The in vitro experiments indicate that the anti-IHD effect of Dan-Shen Decoction may be closely associated with targets such as AKT1 and MAPK1, as well as biological processes such as cell proliferation, inflammatory response, and metabolism. CONCLUSIONS: This study not only provides new insights into the mechanism of Dan-Shen Decoction against IHD, but also provides important information and new research ideas for the discovery of anti-IHD compounds from traditional Chinese medicine.
