Xanthoangelol Alleviates Cerebral Ischemia Reperfusion Injury in Rats

Ischemia/reperfusion (I/R) injury accounts to be a prime cause of neurological deficit following stroke. This study aimed to explore the neuro-protective effects of Xanthoangelol (XAG) on I/R-induced injury in both in vivo and in vitro models. Our data demonstrated that XAG can shrink infarct size and brain edema in middle cerebral artery occlusion (MCAO) model. In addition, XAG was capable of alleviating the neurological deficit in rats that have undergone MCAO procedure. Meanwhile, anti-apoptotic activities of XAG against I/R-induced neuronal injury were evidenced and further illustrated that XAG elicits anti-apoptotic activities by suppressing excessive oxidative stress via nuclear factor erythroid-2-related factor 2 (Nrf2) activation. Overall, our study revealed that XAG displayed the potential to be utilized as a neuroprotective agent against I/R-induced neurological injury.
