OBJECTIVES: This study was designed to investigate metabolic biomarker changes and related metabolic pathways of Butylphthalide (NBP) on cerebral ischemia/reperfusion.
METHODS: In this study, a mouse cerebral ischemia/reperfusion (I/R) model was prepared using the middle cerebral artery occlusion method, and neurobehavioral score and 2, 3, 5-triphenyltetrazolium chloride (TTC) staining experiments were used to confirm the obvious NBP anti-cerebral ischemia effect. The protective effect of NBP in the mouse cerebral I/R model and its metabolic pathway and mechanism were investigated using mouse blood samples.
RESULTS: The metabolic profiles of mice in the I/R+NBP, I/R, and sham groups were significantly different. Under the condition that I/R vs. sham was downregulated and I/R + NBP vs. I/R was upregulated, 88 differential metabolites, including estradiol, ubiquinone-2, 2-oxoarginine, and L-histidine trimethylbetaine, were screened and identified. The related metabolic pathways involved arginine and proline metabolism, oxidative phosphorylation, ubiquitin and other terpenoid-quinone biosynthesis, and estrogen signaling.
CONCLUSIONS: Metabolomics was used to elucidate the NBP mechanism in cerebral ischemia treatment in mice, revealing synergistic NBP pharmacological characteristics with multiple targets.
