Ameliorative Effect of Natural Sesquiterpene Alcohol Cedrol Against Cerebral Ischemia Infarction-In Vitro and In Vivo Studies

In this study, we elucidated the neuroprotective properties of cedrol against ischemic infarction in animal and in vitro studies. A cerebral ischemic/reperfusion model was induced in adult Wistar rats, and oxygen-glucose deprivation/reperfusion was induced in SH-SY5Y neuronal cells and treated with different concentrations of cedrol. The percentage of water content, cerebral infarct, and neurological deficit score was assessed in experimental rats. The acetylcholinesterase activity and inflammatory cytokines were quantified to analyze the anti-inflammatory potency of cedrol. Oxidative stress marker malondialdehyde and antioxidants were quantified to evaluate the antioxidant potency of cedrol in an ischemic condition. The neuroprotective potency of cedrol was confirmed by histopathological analysis of the brain tissue of cedrol-treated I/R-induced rats. In in vitro studies, the MTT and LDH assays were performed in cedrol-treated OGD/R SH-SY5Y cells to analyze the cytoprotective effect of cedrol. The anti-inflammatory property of cedrol was confirmed by quantifying the pro-inflammatory cytokine levels in OGD/R-induced cedrol-treated SH-SY5Y cells. The results obtained prove that cedrol significantly prevents brain edema, neurological deficits, acetylcholinesterase activity, and oxidative damage in ischemic-induced rats. It inhibited neuroinflammation in ischemic-induced rats and also in in vitro models. The neuroprotective effect of cedrol during an ischemic condition was authe...
