    Abstract:
    Objective Salvianolic acid A (SAA) has a significant protective effect on ischemia/reperfusion injury of brain. However, it is not clear for SAA to exert its cerebral protection by targeting at the microvascular endothelial cells of blood brain barrier (BBB). Our previous study demonstrated that SAA could hardly pass through the BBB. This present study was therefore designed to investigate the protective effect of SAA on brain microvascular endothelial cells (BMECs) induced by deprivation and reperfusion with oxygen-glucose. Methods Rat BMECs were treated with oxygen glucose deprivation (OGD), followed by reperfusion (OGD/R). Cell viability was assessed by MTT and the content of reactive oxygen species (ROS) in cells after OGD/R in the absence or presence of SAA. GC-MS based metabolomic platform was applied to evaluate the regulation of SAA on the cellular metabolic perturbation induced by OGD/R. Results OGD/R significantly increased the production of intracellular reactive oxygen species (ROS), and decreased the activity of cells. SAA significantly reduced ROS and improve the cell viability. Metabolomic study revealed distinct perturbation of metabolic pathways of energy metabolism in the BMEC induced by OGD/R, while SAA significantly regulated the perturbed metabolism involved in energy metabolism pathways, especially for intermediates in TCA cycle. Conclusion SAA shows protective effects on BMECs involved in central nervous system.
