Abstract
Stroke is a leading cause of death and disability world-widely. The incidence rate of stroke has been increasing due to the aging population and lifestyle changes. At present, the only drug approved by the US Food and Drug Administration (FDA) for the treatment of ischemic stroke is tissue plasminogen activator (t-PA), but its clinical application is greatly limited because of its narrow time window and bleeding risk. Natural products have a long history of being used in traditional medicine with good safety, making them an important resource for the development of new drugs. Indeed, some natural products can target a variety of pathophysiological processes related to stroke, including oxidative stress, inflammation and neuronal apoptosis. Therefore, the development of high-efficiency, low-toxicity, safe and cheap active substances from natural products is of great significance for improving the treatment alternatives of patients with stroke. This article reviews the neuroprotective effects of 33 natural compounds by searching recent related literature. Among them, puerarin, pinocembrin, quercetin, epigallocatechin-3-gallate (EGCG), and resveratrol have great potential in the clinical treatment of ischemic stroke. This review will provide a powerful reference for screening natural compounds with potential clinical application value in ischemic stroke or synthesizing new neuroprotective agents with natural compounds as lead compounds.
