We examined the inhibition of the expression of some inflammatory genes associated with ischemia-reperfusion (I/R) injury by anthocyanins isolated from black soybean seed coat in tumor necrosis factor-alpha (TNF-alpha)-treated bovine aortic endothelial cells. In addition, its potential use on I/R-injury was investigated using rats subjected to 30-min occlusion of left descending coronary artery followed by 24-h reperfusion. Western blot analysis and luciferase activity assay showed that anthocyanins inhibited TNF-alpha-induced vascular cell adhesion molecule-1, intracellular adhesion molecule-1, and cyclooxygenase-2 levels, which is through NF-kappa B-dependent pathway. Further, anthocyanins protected myocardiac injury from I/R in rats. It is suggested that anthocyanins from black soybean seed coat can be used as a useful drug to modulate cardiovascular disorder.
