Abstract
Stroke and myocardial infarction are among the most common causes of mortality and disability in the world. The ischemic injury underlying these illnesses is complex, involving intricate interplays among many biological functions including energy metabolism, vascular regulation, hemodynamics, oxidative stress, inflammation, platelet activation, and tissue repair that take place in a context- and time-dependent manner. The current drug therapy of choice is to timely resupply the blood to the ischemic tissue; but reperfusion may introduce additional harm to the tissue through a process known as ischemia/reperfusion injury. As such, new drugs that would complement reperfusion by providing neural and cardiovascular protection and by targeting multiple abnormalities in ischemia are receiving increased attention. Scutellarin is an herbal flavonoid glucuronide with multiple pharmacological activities. Owing to its multiple beneficial effects, such as anti-oxidant, anti-inflammation, vascular relaxation, anti-platelet, anti-coagulation, and myocardial protection, scutellarin has been used clinically to treat stroke, myocardial infarction, and diabetic complications. Over the past three decades, clinical and pharmacological studies have accumulated a body of evidence that not only demonstrated these therapeutic effects, but also provided significant insights into the pharmacokinetic behavior, therapeutic profile, and mode of action of scutellarin in humans and animal models. Medicinal modification and new drug delivery methods have led to the development of new derivatives and formulations of scutellarin with improved bioavailability, efficacy, and safety. Here we review the current literature on scutellarin to provide a comprehensive understanding of the pharmacological activity, mechanism of action, toxicity, and therapeutic potential of scutellarin for the treatment of ischemia, diabetic complications, and other chronic diseases.
