Salvianolic acid A, a natural product isolated and purified from the root of Salvia miltiorrhiza Bge. with antioxidant and protective activity, significantly improves glucose metabolism and inhibit oxidative injury as well as protect against impaired vascular responsiveness in STZ-induced diabetic rats, inhibits platelet activation via the inhibition of PI3K, and attenuates arterial thrombus formation in vivo, suggesting that it may be developed as a therapeutic agent for the prevention of thrombotic disorders. Salvianolic acid A is also a matrix metalloproteinase-9 inhibitor, can prevents cardiac remodeling in spontaneously hypertensive rats, and inhibits PDGF-BB-activated HSC proliferation, partially through apoptosis induction while exerting no direct cytotoxicity on primary hepatocytes and HSC-T6 cells under experimental concentrations.
