Vitexin-4-O-glucoside (4-O-Glucosylvitexin) is an orally active natural flavonoid component with multiple pharmacological effects including antioxidation, anti-inflammation, cytoprotection and anti-apoptosis. Vitexin-4-O-glucoside regulates the MAPK signaling pathway by downregulating the phosphorylation levels of JNK and p38, thereby blocking endoplasmic reticulum stress responses. Vitexin-4-O-glucoside alleviates oxidative stress by reducing MDA content and upregulating the activities of SOD and CAT, attenuates inflammation by downregulating the expressions of inflammatory factors TNF-alpha, IL-1beta and IL-6, and also reduces LDH release and inhibits caspase-3 activation. Vitexin-4-O-glucoside effectively improves drug-induced acute liver injury and exerts significant protective effects against myocardial hypoxia/reoxygenation injury. Vitexin-4-O-glucoside can be used in studies on acute liver injury, cardiovascular diseases and myocardial hypoxia-reoxygenation injury[1][2][3][4].
