Uncovering the molecular mechanisms of Fructus Choerospondiatis against coronary heart disease using network pharmacology analysis and experimental pharmacology.

Abstract

Fructus Choerospondiatis (FC), a Mongolian medicine, was mainly used in Mongolian medical theory for the treatment of coronary heart disease (CHD). Nonetheless, the main components and mechanisms of action of FC in the treatment of coronary artery disease have not been studied clearly.

AIM OF THE STUDY:

The aim of this study is to identify the components of FC and analyze the pathways affected by the targets of these components to probe into the potential mechanisms of action of FC on coronary heart disease.

MATERIALS AND METHODS:

Identification of compounds in FC employing high performance liquid chromatography quadrupole time-of-flight tandem mass spectrometry (HPLC-QTOF-MS) method, then further investigate the network pharmacology and molecular docking to obtain potential targets and elucidate the potential mechanism of action of FC in the therapy of CHD. Experimental validation was established to verify the mechanism of FC in vitro.

RESULTS:

21 FC components were identified and 65 overlapping targets were gained. In addition, these ingredients regulated AMPK and PPAR signaling pathway by 65 target genes including IL6, AKT1 and PPARg, etc. Molecular docking displayed that the binding ability of the key target PPARg to FC components turned out to be better. Experimental validation proved that FC treatment decreased the expression of PPARg (p < 0.05) compare with model group, which may be involved in the PPAR signaling pathway.

CONCLUSIONS:

This study was the first to elucidate the mechanism of action of components of FC for the treatment of CHD using network pharmacology. It alleviated CHD by inhibiting the expression of PPARg to attenuate hypoxia/reoxygenation injury, and the results give a basis for elucidating the molecular mechanism of action of FC for the treatment of coronary heart disease.
