Abstract

Toll-like receptor 4 (TLR4) and C5aR1 (CD88) have been recognized as potential therapeutic targets for the reduction of inflammation and secondary damage and improvement of outcome after ischemia and reperfusion (I/R). The inflammatory responses which induce cell apoptosis and necrosis after I/R brain injury lead to a limited process of neural repair. To further comprehend how these targets function in I/R state, we investigated the pathological changes and TLR4 and C5aR1 signaling pathways in vitro and in vivo models of I/R brain injury in this study. Meanwhile, we explored the roles of schisantherin A on I/R brain injury, and whether it exerted neuroprotective effects by regulating the TLR4 and C5aR1 signaling pathways or not. The results showed that schisantherin A significantly reduced the neuronal apoptosis induced by oxygen and glucose deprivation and reperfusion (OGD/R) injury in primary culture of rat cortical neurons. Also, schisantherin A alleviated neurological deficits, reduced infarct volume, attenuated oxidation stress, inflammation and apoptosis in ischemic parietal cortex of rats after middle cerebral artery occlusion and reperfusion (MCAO/R) injury. Moreover, the activated TLR4 and C5aR1 signaling pathways were inhibited by schisantherin A treatment. In conclusion, TLR4 and C5aR1 played a vital role during I/R brain injury in rats, and schisantherin A exhibited neuroprotective effects by TLR4 and C5aR1 signaling pathways. These findings also provided new insights that would aid in elucidating the effect of schisantherin A against cerebral I/R and support the development of schisantherin A as a potential treatment for ischemic stroke.

Abstract

Schisantherin A (STA) is a main bioactive lignan isolated from Schisandra chinensis (Turcz.) Baill., which has been widely used as a tonic in traditional Chinese medicine for many years. Lots of studies have reported that STA exhibited anti-inflammatory and antioxidant effects. This paper was designed to investigate the effects of STA on cognitive function and neurodegeneration in the mouse control of Alzheimer’s disease (AD) induced by Aβ1-42. It was found that successive intracerebroventricular (ICV) administration of STA (0.01 and 0.1mg/kg) for 5days significantly attenuated Aβ1-42-induced learning and memory impairment as measured by the Y-maze test, shuttle-box test and Morris water maze test. Furthermore, STA at a dose of 0.1mg/kg restored the activities of superoxide dismutase (SOD) and glutathione peroxidase (GSH-Px) as well as the levels of Aβ1-42, malondialdehyde (MDA) and glutathione (GSH) to some extent in the hippocampus and cerebral cortex. It also noticeably improved the histopathological changes in the hippocampus. The results suggested that STA might protect against cognitive deficits, oxidative stress and neurodegeneration induced by Aβ1-42, and serve as a potential agent in treatment of AD.

Abstract

ETHNOPHARMACOLOGICAL RELEVANCE:
The fruit of Schisandra chinensis (Turcz.) Baill, has been traditionally used in management of liver diseases and ageing associated neurodegeneration. The bioactive compound from this medicinal plant would be valuable for its potential use in prevention and treatment of Parkinson׳s disease.

AIM OF THE STUDY:
The overall objective of the present study was to understand the neuroprotective effect of schisantherin A, a dibenzocyclooctadiene lignan from the fruit of S. chinensis (Turcz.) Baill, and to elucidate its underlying mechanism of action.

MATERIAL AND METHODS:
This study investigated the protective effect of schisantherin A against selective dopaminergic neurotoxin 6-hydroxydopamine (6-OHDA)-induced neural damage in human neuroblastoma SH-SY5Y cells and zebrafish models. Oxidative stress and related signaling pathways underlying the neuroprotective effect were determined by multiple biochemical assays and Western blot.

RESULTS:
Pretreatment with schisantherin A offered neuroprotection against 6-OHDA-induced SH-SY5Y cytotoxicity. Moreover, schisantherin A could prevent 6-OHDA-stimulated dopaminergic neuron loss in zebrafish. Our mechanistic study showed that schisantherin A can regulate intracellular ROS accumulation, and inhibit NO overproduction by down-regulating the over-expression of iNOS in 6-OHDA treated SH-SY5Y cells. Schisantherin A also protects against 6-OHDA-mediated activation of MAPKs, PI3K/Akt and GSK3β.

CONCLUSION:
These findings demonstrate that schisantherin A may have potential therapeutic value for neurodegenerative diseases associated with abnormal oxidative stress such as Parkinson׳s disease.
