Network pharmacology-based dissection of the bioactive compounds and pharmacological mechanisms of yiqi fumai lyophilized injection for the treatment of heart failure

Abstract

Objective: Yiqi Fumai Lyophilized Injection (YQFM), a Chinese medicine injection, has been widely used for the treatment of cardiovascular diseases, especially heart failure (HF). However, bioactive compounds and underlying mechanisms of YQFM in treating HF remain poorly understood. Materials and Methods: Network pharmacology was employed to investigate the bioactive compounds and mechanisms of YQFM. A compound-target network was constructed to screen bioactive compounds based on contribution index calculation. Then, an adriamycin-induced HF rat model was established to evaluate the cardio-protective effects of YQFM by hematoxylin and eosin staining and enzyme-linked immunosorbent assays. Results: Network pharmacology indicated that YQFM may alleviate HF through 36 compounds and 109 targets. Particularly, ginsenosides Rb1, Rg1, Re, Rf, Rb2, Rh1, schisandrin, and ginsenoside Rc were indicated as the top contributors of YQFM in treating HF. YQFM was predicted to act on multiple targets such as vascular endothelial growth factor A, interleukin-2 (IL-2), IL-6, and IL-1β, as well as to regulate signaling pathways such as hypoxia-inducible factor 1, tumor necrosis factor, VEGF, and PI3K-Akt. The pharmacological study suggested that YQFM could attenuate cardiac injury and up-regulate plasma concentrations of VEGFR-1 and NO in HF rats. Ginsenoside Rb1, as the major contributor from network pharmacology analysis, also showed a cardioprotective effect and up-regulation of VEGFR-1 in plasma. Conclusions: Ginsenosides and schisandrin were predicted as the most important contributors to the cardioprotective effect of YQMF. Ginsenoside Rb1 was proved to alleviate HF and increase the plasma concentration of VEGFR-1.
