Active compounds from Baoyuan decoction with myocardial protection activities and their potential targets / 中国中药杂志

ABSTRACT

Baoyuan decoction (BYD) is a classical Chinese formula for coronary heart disease with Qi deficiency, blood stasis tonifying Qi and Yang deficiency. However, the chemical material basis and underlying action mechanisms of BYD still lack systemic study. In order to clarify the active compounds and the potential action mechanisms of BYD, the oxygen-glucose deprivation/recovery (OGD/R)-induced H9c2 cells injury models was used to screen the monomeric compounds of BYD with myocardial protection activity. PubChem's BioAssay database was then used to analyze the potential targets of active monomeric compounds, classify the predicted biological targets, and analyze the internal relation between active compounds of BYD and biological targets. The screening results showed that BYD aqueous extract and 17 monomeric compounds could significantly increase the survival rate of OGD/R-induced H9c2 myocardial cells. The results of virtual targets screening study showed that 15 monomeric compounds and the potential mechanisms for myocardial protection were related to oxidative stress pathway, calcium ion pathway, mitochondrial protection, anti-apoptosis, etc. These results verified that BYD had myocardial protection effect, which was obtained by network regulation of multi-components and multi-targets. All these results provide the theoretical basis and references for the clinical usage of BYD in treatment of coronary heart disease.
