Biological Activity

Description	Echinacoside, a natural polyphenolic compound, has various biological activities, such as antioxidative, anti-inflammatory, neuroprotective, hepatoprotective, nitric oxide radical-scavenging and vasodilative actions. Echinacoside, one of the phenylethanoids isolated from the stems of Cistanche salsa, elicits neuroprotection by activating Trk receptors and their downstream signal pathways. Echinacoside also has a remarkable antiosteoporotic activity.
In vitro	Echinacoside behaves in vitro as an anti-oxidant and a potent free radical scavenger. It has been shown to rescue SH-SY5Y neuronal cells from TNF-alpha-induced apoptosis. Echinacoside significantly attenuates glutamate-induced neurotoxicity and exhibits neuroprotective activities in vitro^[1]. Echinacoside has significant neuroprotective effects on TNFα-induced apoptosis in SHSY5Y neuronal cells by maintaining mitochondrial function, decreasing the generation of reactive oxygen species, increasing the expression of the antiapoptotic protein Bcl-2 and inhibiting caspase-3 activity through an antioxidation mechanism^[2].
In vivo	Echinacoside has neuroprotective effects in the mouse MPTP model of Parkinson's disease. Treatment with echinacoside improves motor behavior and attenuated the depletion of striatal dopamine, DOPAC and HVA in MPTP-lesioned mice^[1].

Protocol (from reference)

Cell Assay:^{^[2]}	Cell lines SHSY5Y cells Concentrations 1, 10 or 100 μg/ml Incubation Time 36 h Method Cell viability is determined by use of an MTT assay. Cells are seeded in 96-well plates at 1×10⁴ cells per well and grown to 70% confluence in culture medium. The medium is replaced by medium containing various concentrations of echinacoside (1, 10 or 100 μg/ml) and/or 100 ng/ml TNFα. A total of 5 mg/ml MTT is added to each well after 36 h, and the culture continued to incubate for another 4 h at 37 °C. After the medium has been removed, cells and dye crystals are solubilized with 200 μl dimethylsulfoxide (DMSO), and optical density is measured at 570 nm.
