Atheroprotective Effects and Molecular Targets of Tanshinones Derived From Herbal Medicine Danshen

Medicinal plant-derived bioactive compounds modulate multiple therapeutic targets in cardiovascular diseases (CVDs), rendering herb-derived phytochemicals effective against one of the major CVDs-atherosclerosis.Danshen (Salvia milthiorriza Bunge) is a Chinese medicine that has been used in cardio- and cerebro-vascular therapeutic remedies in Asian countries for many years. Emerging evidence from cellular, animal, and clinical studies suggests that major lipophilic tanshinones from Danshen can treat atherosclerotic CVDs. In this review, we highlight recent advances in understanding the molecular mechanisms of tanshinones in treating atherosclerosis, ranging from endothelial dysfunction to chronic inflammation. We also overview new molecular targets of tanshinones, including endothelial nitric oxide synthase, AMP-activated protein kinase, ABC transporter A1, heme oxygenase 1, soluble epoxide hydrolase, 11-hydroxysteroid dehydrogenase, estrogen receptor, and proprotein convertase subtilisin/kexin type 9. Thus, this review provides a new perspective for advancing our understanding of the ancient herb Danshen from modern biomedical perspectives, supporting the possibility of exploiting tanshinones and derivatives as effective therapeutics against atherosclerosis-related cardiovascular and metabolic diseases.
