Danshensu is a traditional Chinese medicine with multiple effects, including antioxidant, anti-inflammatory, and lipid-lowering effects. This study aimed to investigate the mechanism of Danshensu regulating PPARδ for myocardial protection. By establishing a myocardial ischemia-reperfusion injury model, the effects of Danshensu on myocardial injury were observed, and the expression and activation of PPARδ were detected. The results showed that Danshensu significantly reduced myocardial injury markers and enhanced the expression and activation of PPARδ. Further mechanism studies showed that Danshensu inhibited inflammation response and apoptosis and reduced oxidative stress by activating PPARδ pathways, ultimately achieving myocardial protection. The results of this study indicate that regulating PPARδ pathways by Danshensu is a potential strategy for myocardial protection.Keywords: Danshensu; Peroxisome proliferator-activated receptor δ; Myocardial protection; Inflammatory response; Apoptosis; Oxidative stress.
