Abstract

PURPOSE:
Schisanhenol is a compound derived from the fruit of a traditional Chinese herb Schisandra rubriflora. The aim of the present study was to evaluate the effect of Schisanhenol on the cognitive impairment induced by scopolamine.

MATERIAL AND METHODS:
Male mice were randomly divided into three Schisanhenol groups (10, 30, 100 mg/kg), Galantamine group (3 mg/kg), model group (1mg/kg scopolamine), and vehicle control group (normal saline). The learning and memory ability of mice was monitored by water morris maze. Hippocampus of mice were collected after behavioral testing and the activity of SOD, MDA, GSH-px, AChE were measured with standard biochemical procedures. Western blotting was used to analyze the expression of SIRT1, PGC-1α, phosphorylated Tau proteins.

RESULTS:
Intraperitoneal administration of Schisanhenol (10, 30 or 100 mg/kg) significantly attenuated scopolamine-induced cognitive impairment in water morris maze. In addition, Schisanhenol increased the activity of SOD and GSH-px while decreased the content of AChE and MDA. Furthermore, western blotting analysis revealed that Schisanhenol increased the levels of SIRT1 and PGC-1α and decreased the level of phosphorylated Tau protein (Ser 396) significantly in the hippocampal tissues.

CONCLUSIONS:
Our findings indicated that Schisanhenol can attenuate scopolamine-induced learning impairment and enhance cognitive function, the mechanism via improve the cholinergic system and antioxidant ability, activate SIRT1-PGC1α signaling, inhibit the phosphorylation of Tau, and would be an effective candidate against cognitive disorders, such as Alzheimer’s disease.

Abstract

PURPOSE:
Our working hypothesis is that single bioactive phytochemicals with antioxidant properties that are important constituents of Traditional Chinese Medicine (TCM) and their defined mixtures have potential as chemoprotective agents for chronic conditions characterized by oxidative and nitrosative stress, including Alzheimer’s. Here we evaluate the ability of baicalein, crocetin, trans-resveratrol or schisanhenol and two defined mixtures of these TCM phytochemicals to attenuate the toxicity resulting from exposure to cell permeant t-butyl hydroperoxide (tBPH) in wild-type and bioengineered (to express choline acetyltransferase) HEK 293 cells.

METHODS:
Endpoints of tBHP-initiated oxidative and nitrosative stress in both types of HEK 293 cells and its attenuation by TCM constituents and mixtures included cytotoxicity (LDH release); depletion of intracellular glutathione (GSH); formation of S-glutathionylated proteins; oxidative changes to the disulfide proteome; and real-time changes in intracellular redox status.

RESULTS:
At low µM concentrations, each of the TCM constituents and mixtures effectively attenuated intracellular toxicity due to exposure of HEK 293 cells to 50 or 250 µM tBHP for 30 min to 3 h. Confocal microscopy of HEK 293 cells transfected with mutated green fluorescent protein (roGFP2) showed effective attenuation of tBHP oxidation by baicalein in real time. Three redox-regulated proteins prominent in the disulfide proteome of HEK 293 cells were identified by MALDI-TOF mass spectrometry.

CONCLUSIONS:
We conclude that single TCM chemicals and their simple mixtures have potential for use in adjunct chemoprotective therapy. Advantages of mixtures compared to single TCM constituents include the ability to combine compounds with varying molecular mechanisms of cytoprotection for enhanced biological activity; and to combine chemicals with complementary pharmacokinetic properties to increase half-life and prolong activity in vivo.

Abstract

The aim of this paper was to investigate the protective effect of schisanhenol (Sal) isolated from Schisandra rubriflora Rhed, on human ox-LDL-induced bovine aorta endothelial cells (BAECs) apoptosis and intracellular reactive oxygen species (ROS) production in vitro. The BAECs were cultured with ox-LDL (200 microg/ml) in the presence and absence of Sal (10 and 50 micromol L(- 1)) for 24 h. The cytotoxicity of ox-LDL was evaluated by LDH leakage, cell viability and morphological change. Cell apoptosis was estimated by DNA ladder, chromatin condensation, and flow cytometry assay. The intracellular ROS production was detected by using DCF, a ROS probe, with laser confocal microscopy and flow cytometry. Sal was shown to reduce LDH leakage and increase cell viability. Sal also attenuated ox-LDL-induced BAECs apoptosis as indicated in typical internucleosomal DNA degradation (DNA ladder), condensed chromatin, and the sub-G1 peak appearance in flow cytometry assay. Furthermore, Sal was shown to inhibit ROS generation in BAECs with stimulation of ox-LDL. The results indicated that the anti-apoptosis effect of Sal on BACSs might be related to its inhibition of ROS generation.

Description :

Schisanhenol is a natural compound solated from Schisandra rubriflora; UGT2B7 UDP-glucuronosyltransferases inhibitor.IC50 value:Target: in vitro: Schisanhenol exhibited strong inhibition toward UGT2B7, with the residual activity to be 7.9% of control activity [1]. The BAECs were cultured with ox-LDL (200 microg/ml) in the presence and absence of Sal (10 and 50 micromol L(- 1)) for 24 h. The cytotoxicity of ox-LDL was evaluated by LDH leakage, cell viability and morphological change. Cell apoptosis was estimated by DNA ladder, chromatin condensation, and flow cytometry assay. The intracellular ROS production was detected by using DCF, a ROS probe, with laser confocal microscopy and flow cytometry. Sal was shown to reduce LDH leakage and increase cell viability. Sal also attenuated ox-LDL-induced BAECs apoptosis as indicated in typical internucleosomal DNA degradation (DNA ladder), condensed chromatin, and the sub-G1 peak appearance in flow cytometry assay [2].in vivo: Sal significantly impeded production of MDA and loss of ATPase activity induced by reoxygenation following anoxia. Oral administration of Sal induced increase of cytosol glutathione-peroxidase of brain in mice under the condition of reoxygenation following anoxia [4].
