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 CoCl 2 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.

“…The Salviae Miltiorrhizae is effective in the treatment of diabetic complications and anti-fibrosis [ [122] , [123] , [124] ]. In addition, Salviae Miltiorrhizae is also very effective in improving MIRI [ 125 , 126 ]. Four studies [ 29 , 32 , 34 , 35 ] added Asarum.…”

Mechanism of Bazi Bushen capsule in delaying the senescence of mesenchymal stem cells based on network pharmacology and experimental validation

“…Recently, network pharmacology has been widely accepted as an efficient research strategy to explore TCM from the perspective of biological network balance [ 20 , 21 ]. In recent years, great progress has been made in the application of network pharmacology methods to study the scientific connotation of TCM, such as the identification of new targets, biological processes, and signalling pathways, the discovery of potential active compounds, and elucidation of the mechanism of action [ [22] , [23] , [24] , [25] , [26] , [27] ]. Furthermore, previous studies using network pharmacology predict that BZBS can alleviate the cognitive impairment caused by ageing [ 14 , 15 ].…”

A Comprehensive Review on Cardiovascular Disease Detection, Risk Assessment, And Treatment Using A Network Pharmacology Model

“…They frequently serve as the initial interface between people and the healthcare system, thanks to their easy accessibility, longer operating hours, and ability to Significance | Contribution to advancing diagnostic methods, proposing innovative treatment approaches, and demonstrating the effectiveness of pharmacist-led preventive strategies for improving population health. In recent times, the function of pharmacists has gradually evolved from just distributing medications to being providers of assistance and knowledge, with a particular focus on promoting the optimal utilization of medicines Gong et al (2023). An increasing area of study has been on pharmacist-led screening methods, which can significantly enhance public health.…”
