Description:
Salidroside is a prolyl endopeptidase inhibitor, which has cardioprotective, antidiabetic,antidepressant, anxiolytic, anti-tumor, and antioxidant actions. Salidroside alleviates cachexia symptoms in mouse models of cancer cachexia via activating mTOR signalling. It alleviates the pulmonary symptoms of paraquat-induced acute lung injury, at least partially, by repressing inflammatory cell infiltration and the expression of TGF-β1 resulting in delayed lung fibrosis; and it has protective effect against hypoxia-induced cardiomyocytes necrosis and apoptosis by increasing HIF-1α expression and subsequently up-regulating VEGF levels. It may be a potential therapeutic agent for treating or preventing neurodegenerative diseases implicated with oxidative stress.

Anticancer effect of salidroside on colon cancer through inhibiting JAK2/STAT3 signaling pathway.
Salidroside is considered to have anti-tumor properties. We investigate its effects on colon carcinoma SW1116 cells.
METHODS AND RESULTS:
Cell viability was assessed by CCK-8. Propidium iodide (PI) staining was used to determine the cell cycle by flow cytometry. The migration and invasion were detected by Transwell. Western blot was used to detect the expression of STAT3 signal related proteins. As the result, high concentrations of Salidroside (10, 20. 50 μg/ml) significantly inhibited proliferation of SW1116 cells in a parallelly, cell cycle arrest was increased at the G0/G1 phase after Salidroside treatment. Furthermore, Salidroside inhibited migration and invasion of SW1116 cells. Salidroside treatment decreased proteins expression of phosphorylation levels in JAK2/STAT3 signaling, while MMP-2 and MMP-9 proteins levels were decreased and protein expression of VEGF and VEGFR-2 were down-regulated.
CONCLUSIONS:
In Conclusion, Salidroside inhibited proliferation, decreased the migration and invasion of SW1116 cells in JAK2/STAT3-dependent pathway, the specific mechanisms need further study.

Salidroside ameliorates insulin resistance through activation of a mitochondria-associated AMPK/PI3K/Akt/GSK3β pathway.
Recent reports have suggested that Salidroside could protect cardiomyocytes from oxidative injury and stimulate glucose uptake in skeletal muscle cells by activating AMP-activated protein kinase (AMPK). The aim of this study was to evaluate the therapeutic effects of Salidroside on diabetic mice and to explore the underlying mechanisms.
METHODS AND RESULTS:
The therapeutic effects of Salidroside on type 2 diabetes were investigated. Increasing doses of Salidroside (25, 50 and 100 mg·kg(-1) ·day(-1)) were administered p.o. to db/db mice for 8 weeks. Biochemical analysis and histopathological examinations were conducted to evaluate the therapeutic effects of Salidroside. Primary cultured mouse hepatocytes were used to further explore the underlying mechanisms in vitro. Salidroside dramatically reduced blood glucose and serum insulin levels and alleviated insulin resistance. Hypolipidaemic effects and amelioration of liver steatosis were observed after Salidroside administration. In vitro, Salidroside dose-dependently induced an increase in the phosphorylations of AMPK and PI3K/Akt, as well as glycogen synthase kinase 3β (GSK3β) in hepatocytes. Furthermore, Salidroside-stimulated AMPK activation was found to suppress the expression of PEPCK and glucose-6-phosphatase. Salidroside-induced AMPK activation also resulted in phosphorylation of acetyl CoA carboxylase, which can reduce lipid accumulation in peripheral tissues. In isolated mitochondria, Salidroside inhibited respiratory chain complex I and disturbed oxidation/phosphorylation coupling and moderately depolarized the mitochondrial membrane potential, resulting in a transient increase in the AMP/ATP ratio.
CONCLUSIONS:
Salidroside exerts an antidiabetic effect by improving the cellular metabolic flux through the activation of a mitochondria-related AMPK/PI3K/Akt/GSK3β pathway.

Salidroside rescued mice from experimental sepsis through anti-inflammatory and anti-apoptosis effects.
Salidroside (SDS) is the main effective component of Rhodiola rosea L with a variety of pharmacologic properties. The objective of this study was to investigate the efficacy of SDS in the treatment of experimental sepsis in mice and explore the possible underlying action mechanisms.
METHODS AND RESULTS:
Sepsis was induced in C57BL/6 male mice via cecal ligation and puncture (CLP). The animals were divided into three groups as follows: sham, CLP, and CLP plus SDS. SDS (50 mg/kg) was injected intraperitoneally 1 h after operation. Postoperative survival of the mice, bacterial clearance in blood and peritoneal lavage fluid, cytokine secretion in blood, and histology of lung were evaluated. In addition, apoptosis of immune cells in the spleen and thymus were examined, respectively. SDS administration prolonged the survival of the septic mice, inhibited the proinflammatory responses, and enhanced bacterial clearance. It also alleviated the pathologic changes in the lung and inhibited the apoptosis of immune cells in the spleen and thymus after CLP challenge.
CONCLUSIONS:
SDS exerts a protective effect in CLP-induced sepsis by attenuating the proinflammatory responses, enhancing bacterial clearance, and preserving adaptive immunity. SDS may be a promising therapeutic strategy for the treatment of sepsis.

Salidroside attenuates beta amyloid-induced cognitive deficits via modulating oxidative stress and inflammatory mediators in rat hippocampus.
Beta amyloid (Aβ)-induced oxidative stress and chronic inflammation in the brain are considered to be responsible for the pathogenesis of Alzheimer's disease (AD). Salidroside, the major active ingredient of Rhodiola crenulata, has been previously shown to have antioxidant and neuroprotective properties in vitro. The present study aimed to investigate the protective effects of Salidrosideon Aβ-induced cognitive impairment in vivo.
METHODS AND RESULTS:
Rats received intrahippocampal Aβ1-40 injection were treated with Salidroside (25, 50 and 75 mg/kg p.o.) once daily for 21 days. Learning and memory performance were assessed in the Morris water maze (days 17-21). After behavioral testing, the rats were sacrificed and hippocampi were removed for biochemical assays (reactive oxygen species (ROS), superoxide dismutase (SOD), glutathione peroxidase (GPx), malondialdehyde (MDA), acetylcholinesterase (AChE), acetylcholine (ACh)) and molecular biological analysis (Cu/Zn-SOD, Mn-SOD, GPx, nicotinamide adenine dinucleotide phosphate (NADPH) oxidase, nuclear factor κB (NF-κB), inhibitor of κB-alpha (IκBα), cyclooxygenase-2 (COX-2), inducible nitric oxide synthase (iNOS), receptor for advanced glycation end products (RAGE)). Our results confirmed that Aβ1-40 peptide caused learning and memory deficits in rats. Further analysis demonstrated that the NADPH oxidase-mediated oxidative stress was increased in Aβ1-40-injected rats. Furthermore, NF-κB was demonstrated to be activated in Aβ1-40-injected rats, and the COX-2, iNOS and RAGE expression were also induced by Aβ1-40. However, Salidroside (50 and 75 mg/kg p.o.) reversed all the former alterations.
CONCLUSIONS:
Thus, the study indicates that Salidroside may have a protective effect against AD via modulating oxidative stress and inflammatory mediators.
