Ginsenoside Rg3 plays an important role in its effect on the Na+ channel. Treatment with Ginsenoside Rg3 reversibly inhibits the inward Na+ peak current (INa) with an IC50 of 32.2±4.5 μM, and the inhibition is voltage-dependent[1]. Ginsenoside Rg3 at 100 μM inhibits the hKv1.4 channel currents by an average of 65%.The Ginsenoside Rg3 effect is concentration-dependent and reversible. The IC50 value and Hill coefficient are 32.6±2.2 μM and 1.59±0.13, respectively[2]. Ginsenoside Rg3 shows the significant inhibition of NF-κB activity thereby reduced COX-2 expression. To examine the cytotoxicity of Ginsenoside Rg3 on IL-1β-induced inflamed A549 cells, the cells are firstly treated with IL-1β (10 ng/mL) for 4 h and treated with 100 to 900 ng/mL concentration of Ginsenoside Rg3 for 12 h. Cell viability is analyzed using an MTT assay. There is no observed cytotoxicity of Ginsenoside Rg3 in IL-1β-induced inflamed A549 cells compared to only PBS-treated cells (Con).To obtain the anti-inflammatory effects of Ginsenoside Rg3 on inflammation induced human lung epithelial cells, A549 cells inflammation is induced by IL-1β (10 ng/mL) and then treated by 5 μM of Dexamethasone (Dex) or 900 nM of Rg3. The NF-κB activation is analyzed by a western blot analysis to evaluate the effect of Ginsenoside Rg3 treatment on A549 cells. Phospho-NF-κB p65/total NF-κB p65 densitometry in the cells treated with Rg3 shows the significant decrease compared to IL-1β-induced inflamed A549 cells. The meaning of reducing the ratio of p-p65/p65 by Rg3 treatment is associated with NF-κB activation. Ginsenoside Rg3 also downregulates the expression of COX-2 effectively[3].

Cell Assay
[3]

MTT assays are performed to evaluate the cytotoxicity of Ginsenoside Rg3 on inflamed cells. Ten thousands of A549 cells cultured each well of 96-well plate and are incubated at 37°C and 5% CO2 overnight. After serum starvation using DMEM low glucose without FBS, the medium is changed into RPMI containing IL-1β (10 ng/mL) and the cells are incubated at 37°C and 5% CO2 for 4 h. After 4 h incubation, the cells are treated with Ginsenoside Rg3 (100-900 nM) for 12 h. Thirty microliters of MTT solution (5 mg/mL) is added to each well and the cells are incubated for 2 h. After 2 h incubation in cell culture incubator, the medium containing MTT solution of each well is removed and 50 μL of DMSO is added. Using an automated spectrophotometric plate reader at 570 nm, the optical density of formazan is measured[3].

Mice[4]
The mice used are heterozygous, double transgenic animals expressing both human APP(K670N/M671L) and PS1(M146L) proteins. These Alzheimer disease model mice are age-matched (3 months old) in all experiments with wild-type littermates. Both sets of mice are produced by crossing heterozygous APP mice with heterozygous PS1 mice and are weaned at 3 weeks and genotyped by PCR of digested tail samples. Ginsenoside Rg3 is prepared in a saline solution containing 0.01% DMSO at a concentration of 10 mg/kg of body weight. Ginsenoside Rg3 (or saline with 0.01% DMSO for controls) is administered daily via intraperitoneal injection. After sacrifice, one hemibrain from each mouse is frozen on dry ice, homogenized in sucrose buffer, and extracted via formic acid for Aβ quantification using a commercial sandwich ELISA kit.

Ginsenoside Rh2 induces the activation of two initiator caspases, caspase-8 and caspase-9 in human cancer cells. Ginsenoside Rh2 induces cancer cell apoptosis in a multi-path manner and is therefore a promising candidate for anti-tumor drug development. Ginsenoside Rh2 triggers p53-dependent Fas expression and consequent activation of caspase-8 and p53-independent caspase-9-mediated intrinsic pathway to cause cancer cell death.The cytotoxic activity of Ginsenoside Rh2 in the human tumor cell lines HeLa, SK-HEP-1, SW480, and PC-3 is assessed by MTT. The cell viability of HeLa cells is remarkably inhibited by Ginsenoside Rh2, with an IC50 value of 2.52 μg/mL, whereas SK-HEP-1 and SW480 cells are less sensitive to Ginsenoside Rh2, with IC50 values of 3.15 μg/mL and 4.06 μg/mL, respectively. PC-3 cells are the least vulnerable to Ginsenoside Rh2, with an IC50 value of 7.85 μg/mL, 3-fold higher than HeLa cells[1].

A total of 15 days following B16-F10 cell injection, tumor sizes from the 3 tumor bearing groups are measured. The tumor sizes in the G-L group and G-H group (G-L and G-H refer to a low or high dose of ginsenoside Rh2 injection) are reduced compared with the tumor group (P<0.05). The survival analysis reveals that the Ginsenoside Rh2 treated groups survive longer than the untreated tumor group and the effect is dose-dependent (P<0.05)[2].

HeLa, SK-HEP-1, SW480, and PC-3 cells are treated with Ginsenoside Rh2 (7.5 μg/mL) in serum free media for indicated time periods and then are harvested. Fifty micrograms of cell lysates are incubated with 200 nM Ac-DEVD-AFC (for caspase-3), Ac-IETD-AFC (for caspase-8), and Ac-LEHD-AFC (for caspase-9) in a reaction buffer containing 20 mM HEPES, pH 7.4, 100 mM NaCl, 10 mM DTT, 0.1% CHAPS, and 10% sucrose at 37°C for 1 h. The reaction is monitored by fluorescence emission at 535 nm and excitation at 405 nm[1].

Determination of cell viability is performed by using MTT assay, which is used to calculate the growth inhibition induced by increasing concentrations of drug. Briefly, exponentially growing HeLa, SK-HEP-1, SW480, and PC-3 cells are seeded into a 96-well plate at 1×104 cells/well in triplicate. After incubation for 24 h, cells are treated with increasing concentration of Ginsenoside Rh2 (1, 2.5, 5, 7.5 and 10 μg/mL) in serum free media for 48 h. At the end of treatment, 20 μL of MTT (5 mg/mL) is added to each well and incubated for an additional 4 h. The formazan grains formed by viable cells are solubilized with DMSO, and the color intensity is measured at 550 nm with an ELISA reader[1].

Male C57BL6 mice (3-4 weeks old) are randomly arranged into 4 groups of 80 mice: Tumor group, G-L group, G-H group and Control group. G-L and G-H refer to a low or high dose of ginsenoside Rh2 injection. For the tumor group, G-L group and G-H group, the B16-F10 cell line is injected into the mice. These 3 groups become tumor bearing groups. For the control group, the same volume of PBS is injected instead. Ginsenoside Rh2 is injected into the left back of mice in the G-L and G-H groups. The dose for the G-H group is 0.5 mg/kg or 0.2 mg/kg for G-L group, every 2 days after day 5. PBS is injected in the tumor and control groups at the same time points.

Rat brain microsomal Na+, K+-ATPase activity is inhibited significantly and rapidly by Ginsenoside Rb1. The IC50 of Ginsenoside Rb1 for Na+,K+-ATPase is 6.3±1.0 μM. The inhibition is enhanced with increasing the concentration of Ginsenoside Rb1 or decreasing that of Na+ and K+. Kinetic analysis reveals that Ginsenoside is an uncompetitive inhibitor with respect to ATP[1]. Ginsenoside Rb1 significantly inhibits the activation of interleukin-1 receptor-associated kinase-1 (IRAK-1), IKK-β, NF-κB, and MAP kinases (ERK, JNK, and p-38); however, interaction between LPS and Toll-like receptor-4, IRAK-4 activation and IRAK-2 activation are unaffected[2]. Ginsenoside Rb1 is an ingredient of a Chinese medicine Panax ginseng. Ginsenoside Rb1 is a major bioactive compound in the regulating pregnane X receptor (PXR)/NF-κB signaling. Ginsenoside Rb1 is the compound with potent anti-inflammatory activity in ginseng saponin extract (GSE). The concentration for Ginsenoside Rb1 (10 μM) is optimized from a preliminary study to ensure sufficient anti-inflammatory activity and without apparent cytotoxicity. Ginsenoside Rb1 significantly reduces TNF-α-induced upregulation of IL-1β and iNOS mRNA levels, and restores the mRNA levels of PXR and CYP3A4 in LS174T cells. TNF-α causes a significant reduction in PXR protein levels and increase in the ratio of phosphorylated to total NF-κB p65, both of which are significantly abrogated by Ginsenoside Rb1[3].

Ginsenoside Rb1 (Rb1), an ingredient of a Chinese medicine Panax ginseng, has beneficial effects on mesentery microvascular hyperpermeability induced by Lipopolysaccharide (LPS) and the underlying mechanisms. In some rats, Ginsenoside Rb1 (5 mg/kg per hour) is administrated through the left jugular vein 30 min after LPS infusion. Ginsenoside Rb1 decreases caveolae number in endothelial cells of microvessels. Ginsenoside Rb1 ameliorates microvascular hyperpermeability after the onset of endotoxemia and improves intestinal edema through inhibiting caveolae formation and junction disruption, which is correlated to suppression of NF-κB and Src activation[5].

Mice[4]
Male C57BL/6 mice (9-12 weeks old; 17-22 g) are randomly allocated into eight groups (n=8 in each group): (1) Sham surgical preparation including isolation of the superior mesenteric artery (SMA) without occlusion is performed (Sham); (2) mice are subjected to II/R without treatment (II/R); (3) mice are subjected to II/R with treatment of normal saline 10 minutes before reperfusion (II/R+NS); (4), (5) mice are treated with 30 mg/kg (II/R+Rb1-30) or 60 mg/kg (II/R+Rb1-60) Ginsenoside Rb1, in which surgery is performed as in the II/R group with administration of the Ginsenoside Rb1 intraperitoneally 10 minutes before reperfusion; (6) mice are subjected to Sham surgery and treated with ATRA (ATRA+Sham), which is the inhibitor of Nrf2/ARE signaling pathway; (7) mice are subjected to II/R and treated with ATRA (ATRA+II/R); (8) mice are subjected to II/R and treated with ATRA and 60 mg/kg Ginsenoside Rb1 as group 5 (ATRA+II/R+Rb1-60). During the last two weeks before the operation, the mice in the group 6, 7, 8 receive ATRA i.p. daily at 10 mg/kg and fed on a vitamin A-deficient diet, and the mice in the other groups receive the equivalent volume of corn oil and fed on a control normal diet.
Rats[5]
Male Wistar rats weighing 200-250 g are used. The rats are randomly divided into four groups, 26 animals in each. After being anesthetized with urethane (2 g/kg body wt im), the left femoral vein and left jugular vein of the rat are cannulated. In the LPS group, LPS solution in saline is infused (5 mg/kg per hour) for 90 min via the left femoral vein. The vehicle, instead of LPS solution, is administrated in Sham and Ginsenoside Rb1 alone (Rb1, 5 mg/kg) groups. In the Rb1 posttreatment (LPS+Rb1) group, Ginsenoside Rb1 solution is infused continuously through the left jugular vein 30 min after LPS administration at the dose of 5 mg/kg. Ginsenoside Rb1 solution and the same volume of saline are infused in Ginsenoside Rb1 and Sham groups, respectively, without subsequent LPS administration. In a separate set of experiments, the rats are anesthetized with 2% penobarbital sodium (60 mg/kg body wt ip), and saline, LPS, and Ginsenoside Rb1. After recovery from anesthesia, the animals are allowed access to water and rodent chow, and survival rate is recorded over time until 4 days after LPS stimulation.

生物活性

Ginsenoside Ro (Polysciasaponin P3; Chikusetsusaponin 5; Chikusetsusaponin V) exhibits a Ca2+-antagonistic antiplatelet effect with an IC50 of 155  μM. Ginsenoside Ro reduces the production of TXA2 more than it reduces the activities of COX-1 and TXAS.

IC50 & Target[1][2]

TXA2

 

Ca2+

 

体外研究
(In Vitro)

Ginsenoside Ro in Panax ginseng is a beneficial novel Ca2+-antagonistic compound and may prevent platelet aggregation-mediated thrombotic disease. Ginsenoside Ro dose-dependently reduces thrombin-stimulated platelet aggregation, and IC50 is approximately 155 μM[1]. Ginsenoside Ro inhibits TXA2 production to abolish thrombin-induced platelet aggregation. Thromboxane A2 (TXA2) induces platelet aggregation and promotes thrombus formation. Ginsenoside Ro dose-dependently (50-300 μM) reduces the TXB2 level that is induced by thrombin; Ginsenoside Ro (300 μM) inhibits the thrombin-mediated elevation in TXB2 level by 94.9%. COX-1 activity in the absence of Ginsenoside Ro (negative control) is 2.3±0.1 nmol/mg protein. However, Ginsenoside Ro dose-dependently (50-300 μM) reduces its activity; at 300 μM, COX-1 activity is reduced by 26.4% of that of the negative control. TXA2 synthase (TXAS) activity in the absence of Ginsenoside Ro (negative control) is 220.8±1.8 ng/mg protein/min. However, Ginsenoside Ro dose-dependently (50-300 μM) reduces its activity; at 300 μM, TXAS activity is reduced by 22.9% of that of the negative control. The inhibitory effect of Ginsenoside Ro (300 μM) on TXB2 production (94.9%) is significantly higher than those on COX-1 (26.4%) and TXAS (22.9%) activities[2]. To assess the toxicity of Ginsenoside Ro in Raw 264.7 cells, they are first treated with various concentrations (10 μM, 50 μM, 100 μM, and 200 μM) of Ginsenoside Ro for 24 h. Ginsenoside Ro exhibits no significant dose dependent toxicity. The effect of Ginsenoside Ro is next determined on cell viability and ROS levels, a marker of oxidative stress, following treatment with 1 μg/mL LPS. LPS reduces cell viability by ∼70% compared with nontreated controls. Pretreatment with 100 μM and 200 μM Ginsenoside Ro for 1 h prior to 1 μg/mL LPS incubation for 24 h leads to a significant increase in cell viability. The changes in ROS levels and NO production are consistent with the effects of Ginsenoside Ro on viability[3].

体内研究
(In Vivo)

Ginsenoside Ro dissolved in water is administrated by gavage to mice at doses of 25 and 250 mg/kg/day for 4 days before i.v. injection of HT29 in order to keep blood concentrations of Ginsenoside Ro above a certain level before HT29 i.v. injection followed by 40 days of oral administration of Ginsenoside Ro to the mice. After 38 days of treatment, the animals are euthanized, and the number of pulmonary metastatic nodules is counted in addition to evaluation of toxicity of Ginsenoside Ro and mouse pathology by HT29. Ginsenoside Ro (250 mg/kg/day) produces a significant decrease in the number of tumor nodules on the lung surface, yielding inhibition rates of 88% (P < 0.01)[4].

Kinase Assay
[2]

The microsomal fraction of platelets is preincubated with Ozagrel (11 nM, IC50), a positive control, or with various concentrations of Ginsenoside Ro and other reagents at 37°C for 5 min. The reaction is initiated by adding prostaglandin H2, and the samples are incubated at 37°C for 1 min; the reaction is terminated by adding citric acid (1 M). After neutralization with 1 N NaOH, the amount of TXB2 is determined using a TXB2 EIA kit[2].

Cell viability is determined with an MTT assay kit. Briefly, Raw 264.7 cells are plated in 48-well plates at a density of 2.0×104 cells per well, incubated for 24 h, and treated with various concentrations of Ginsenoside Ro for 24 h. How 1 h of pretreatment with Ginsenoside Ro (50 μM, 100 μM, and 200 μM) affects the viability of Raw 264.7 cells is then investigated treated with 1 μg/mL LPS for 24 h. After the incubation period, 10 μL of MTT reagent is added to each well and incubated for 3 h at 37°C in 5% CO2. The resulting formazan crystals are subsequently dissolved in MTT solubilization solution. The absorbance is determined at 540 nm using a microplate reader[3].

Mice[4]
Female BALB/c mice (20-25 g, 6-8 weeks old) are used. The experimental model of lung metastasis is established by tail vein injection of HT29 cells to mimic the dissemination of CTCs. HT29 cells in the number of 2×106 cells in 0.2 mL PBS are infected into the tail vein of six-week-old female Balb/c mice. Before the HT29 inoculation, oral gavage pretreatment of PBS-suspended B (Ginsenoside Ro) is given daily for 4 days, followed by a 40-day treatment. Treatment groups (N = 10) include: 0 mg/kg, 25 mg/kg and 250 mg/kg Ginsenoside Ro. Body weight is measured and recorded every four days. Mice are sacrificed after 40 days of tumor metastasis and growth and 44 days of treatment with B. The number of surface lung metastasis nodules is evaluated in each treatment group. Slides with 4-5 μm thick lung section are prepared, paraffin embedded and then stained with hematoxylin and eosin[4].

Ginsenoside Rg1 promotes the proliferation and differentiation of human dental pulp cells (hDPCs). The proliferative ability of hDPCs in Ginsenoside Rg1 is significantly enhanced (p<0.05), especially in the Ginsenoside Rg1 (5 μM) group. ALP activity and gene expressions of DSPP and DMP1 are increased in the induction group, Ginsenoside Rg1 group, and their combination group compared with the control group (p<0.05)[3]. In the RAW264.7 cells stimulated by lipopolysaccharides (LPS) , the level of p-IκBα and p-p65 is significantly higher than in controls and PPAR-γ levels are significantly lower. Treatment with Rg1 vitro inhibits IκBα phosphorylation, reduces NF-κB nuclear translocation and upregulates PPAR-γ expression[2].

In the inflamed joints of adjuvant-induced arthritis (AIA) rats, the level of p-IκBα and p-p65 is significantly higher than in controls and PPAR-γ levels are significantly lower. Treatment with Ginsenoside Rg1 in vivo inhibits IκBα phosphorylation, reduces NF-κB nuclear translocation and upregulates PPAR-γ expression[2]. Ginsenoside Rg1 (G-Rg1) and Ginsenoside Rg2 (G-Rg2) reduce the escape latencies on the last two training days compared to the Alzheimer’s disease (AD) model group (p<0.05). In the spatial exploration test, the total time spent in the target quadrant and the number of mice that exactly crossed the previous position of the platform are clearly shorter and lower, respectively, in the AD model group mice than in the normal control group mice (p<0.01), a trend that is reversed by treatment with Ginsenoside Rg1 and Ginsenoside Rg2 (Ginsenoside Rg1, p<0.01; Ginsenoside Rg2, p<0.05). Treatment with Ginsenoside Rg1 and Ginsenoside Rg2 effectively improve cognitive function of the mice that have declined due to AD. Ginsenoside Rg1 and Ginsenoside Rg2 reduce Aβ1-42 accumulation in APP/PS1 mice. In the Ginsenoside Rg1 and Ginsenoside Rg2 treated mice, the pathological abnormalities observed in the APP/PS1 mice are gradually ameliorated. Clear nucleoli and light brown, sparsely scattered Aβ deposits are visible[1].

Cell Assay
[3]

hDPCs are incubated with different concentrations of Ginsenoside Rg1 (0.1, 0.5, 2.5, 5, 10 and 20 μM) . The effects of Ginsenoside Rg1 on the proliferative ability of hDPCs are evaluated by a fibroblast colony forming test, MTT assay and flow cytometry for cell cycle. The control group, osteogenic induction group, Ginsenoside Rg1 (5 μM) group and combination group are designed, and alkaline phosphatase (ALP) activity and FQ-PCR for gene expressions of dentine sialophosphoprotein (DSPP) and dentine matrix protein 1 (DMP1) are performed to evaluate the differentiation of hDPCs[3].

Animal Administration
[1]

Mice[1]
Male APP/PS1 mice, weighing 20±2 g, and male C57BL/6J mice, weighing 20±2 g, are used. The animals are maintained in an air-conditioned animal center at 23±2°C and a relative humidity of 50±10%, with a natural light-dark cycle. Food and water are available ad libitum. After acclimatization for 1 wk, the mice are divided into four groups (n=10 in each group): the normal control group, the AD model group, the Ginsenoside Rg1 group, and the Ginsenoside Rg2 group. According to the concentration-response curves, the mice in the Ginsenoside Rg1 and Ginsenoside Rg2 groups are injected intraperitoneally once daily with Ginsenoside Rg1 and Ginsenoside Rg2 (30 mg/kg), respectively, dissolved in saline. The mice in the AD model group (APP/PS1 mice) and the normal control group (C57BL/6J nontransgenic littermates) are treated with isodose saline (0.9% w/v). All mice are treated for 1 mo before brain metabolite profiling.

[1]

B16BL6 cells are cultured in Dulbecco’s modified Eagles medium supplemented with 10% fetal bovine serum and 1% Penicillin-Streptomycin at 37°C in a humidified 95% air/5% CO2 atmosphere. Cell viability is determined for Ginsenoside F1 and metabolite 1 using MTT conversion to formazan. Cells are seeded at a density of 1×105 cells/well in a 96-well plate, cultured for 24 h, and treated with various concentrations from 1 μM to 200 μM of Ginsenoside F1 and metabolite 1 for 5 d. Finally, 10 μL of MTT (5 mg/mL in PBS) is added to each well. Cells are incubated at 37°C for 3 h, and then DMSO (100 μL) is added to dissolve the formazan crystals. The absorbance is measured at 570 nm with the reference wavelength of 630 nm using an ELISA reader[1].

Mice[2]
Six-week-old (17±1 g) male C57BL/6 mice and ApoE-/- mice with a C57BL/6 background are maintained in a temperature-controlled facility (temperature: 22±1°C; humidity: 60%) with a 14 h light/10 h dark cycle in conventional cages. Forty mice are randomly divided into four experimental groups (n=10/group): (I) C57BL/6 N mice, the control group; (II) ApoE-/- mice group; (III) ApoE-/- mice+ Ginsenoside F1 group; (IV) ApoE-/- mice+Probucol group. All mice are fed with a high fat diet (HFD, 0.3% cholesterol and 20% pork fat) for 8 weeks. Ginsenoside F1 (50 mg/kg/day, i.g.) and Probucol (2 g/kg, i.g.) are dissolved in carboxymethyl cellulose sodium (CMC-Na). Oral administration is given to mice every day for 8 weeks. The control and model groups receive the aseptic 0.5% CMC-Na treatment every day (i.g., 0.1 mL/10g) [2].

体外研究
(In Vitro)

Ginsenoside Re is a well-known traditional Chinese medicine, which decreases the β-site amyloid precursor protein cleaving enzyme 1 (BACE1) mRNA and protein levels and inhibits BACE1 activity in the N2a/APP695 cells. Ginsenoside Re also significantly increases the PPARγ protein and mRNA levels.To prevent Ginsenoside Re from having a cytotoxic effect on the N2a/APP695 cells, the cell viability is first determined by the MTT assay. The N2a/WT and N2a/APP695 cells are treated with increasing concentrations of Ginsenoside Re (0-200 µM) for 24 h. Ginsenoside Re concentrations under 100 µM do not affect the viability of the N2a/WT and N2a/APP695 cells, whereas the 150 µM Ginsenoside Re concentration markedly decreases the survival rate of the N2a/WT and N2a/APP695 cells. Incubation with Ginsenoside Re at a 200 µM concentration for 24 h reduces the viability of the N2a/WT and N2a/APP695 cells by 15.58% and 26.82%, respectively. These data indicate that Ginsenoside Re treatment within the range of 0-100 µM for 24 h is safe for the N2a/WT and N2a/APP695 cells (P>0.05)[1].

体内研究
(In Vivo)

Ginsenoside Re reduces insulin resistance in 3T3-L1 adipocytes and high-fat diet (HFD) rats through inhibition of JNK and NF-κB activation[2]. Intraperitoneal injection of lipopolysaccharide (LPS) at a dose of 20 mg/kg is lethal to mice, and 70% to 80% of the mice die within 60 h. However, pretreatment of the mice with Rg1 or Ginsenoside Re increases their survival rates in a dose-dependent manner. With the doses of Rg1 or Ginsenoside Re increase from 2.5 to 5 mg/kg, the survival rate is elevated from 60% to 90% (Rg1) or from 30% to 40% (Ginsenoside Re). All the mice administered Rg1 at a minimal dose of 10 mg/kg are protected from death compared to 80% survival of mice treated with an equal dose of Ginsenoside Re. To protect all the mice, 20 mg/kg Ginsenoside Re is needed. To investigate the anti-inflammatory potential of Rg1 and Ginsenoside Re, 1 mg/kg Rg1 or Ginsenoside Re is injected into rats and then challenged the animals with LPS. The injection procedure itself causes a transient stress-induced increase in body temperature of ~1.2°C in each group. Thereafter, LPS-challenged rats without pretreatment develope a robust biphasic fever, with the first peak reaching ~1.5°C at 2 h and the second peak reaching 1.8°C at 4 h. In contrast, the temperature changes for the Rg1-, Ginsenoside Re-, and TAK-242-treated groups are only 0.9, 1.2, and 0.8°C at 2 h and 1.3, 1.4, and 1.0°C at 4 h, respectively. Pretreatment with Rg1, Ginsenoside Re, or TAK-242 significantly attenuates LPS-induced alterations in body temperature[3].

Cell Assay
[1]

To explore the cytotoxic effect of Ginsenoside Re on N2a/APP695 cells, cell proliferation is assessed using the MTT assay. The cells are treated with increasing doses of Ginsenoside Re (0, 25, 50, 100, 150, and 200 µM) for 24 h. The MTT assay is performed after the treatments. The cells are incubated for 4 h at 37 °C with 0.5 mg/mL of MTT dissolved in fresh complete medium. The dark blue formazan crystals are dissolved in DMSO, and the absorbance is measured on a microplate reader using a reference wavelength of 630 nm and a test wavelength of 490 nm. The data are expressed as the mean percentages of viable cells versus the control[1].

MCE has not independently confirmed the accuracy of these methods. They are for reference only.

Animal Administration
[3]

Mice[3]
To examine the prophylactic effect of Rg1 and Ginsenoside Re on LPS-induced lethality, 6- to 8-week-old BALB/c mice are randomly assigned to 7 groups with 10 mice in each group. The mice are either left untreated or subcutaneously injected with 2.5, 5, 10, or 20 mg/kg Rg1, 20 mg/kg Ginsenoside Re, or 5 mg/kg TAK-242 3 times at 30-min intervals and then challenged with LPS (20 mg/kg) 15 min later. To test the therapeutic effect of Rg1 and Ginsenoside Re on LPS-induced lethality, BALB/c mice are assigned to 5 groups with 10 mice in each group. The mice are injected intraperitoneally (i.p.) with 20 mg/kg LPS. Fifteen minutes later, mice are subcutaneously injected with 10 mg/kg Rg1, 20 mg/kg Ginsenoside Re, or 5 mg/kg TAK-242 3 times at 30-min intervals or left untreated. Survival rates are recorded for 60 h.
Rats[3]
Sprague Dawley rats are intravenously administered saline solution, 1 mg of Rg1/kg body weight (1 mg/kg Rg1), 1 mg/kg Ginsenoside Re, or 1 mg/kg TAK-242. Fifteen minutes later, rats are challenged with 2.5 μg/kg LPS. Body temperature is measured before and after drug administration. Anticoagulated blood samples with EDTA are collected for white blood cell (WBC) counts at indicated time points using a ProCyte Dx automatic blood cell analyzer. Additional blood samples are collected at 4 h post-drug injection and used for preparation of serum to analyze proinflammatory mediators. The proinflammatory cytokine responses are detected by Western blot assay.

MCE has not independently confirmed the accuracy of these methods. They are for reference only.

Ginsenoside Rg6 inhibits TNF-α-induced NF-κB transcriptional activity with an IC50 of 25.12±1.04 μM in SK-Hep1 cells, consistent with the data from HepG2 cells[1]. Ginsenoside Rg6 exhibits obvious anti-proliferative and apoptosis-inducing effects when it is applied to JK cells in vitro. Ginsenoside Rg6 blocks S arrest in the cell cycle. CCK-8 method shows that after Ginsenoside Rg6 is used, several groups with different concentrations obviously inhibits JK cell proliferation in human lymphocytoma, with evident dose dependency. Based on IC50, the median inhibitory concentration of Ginsenoside Rg6 is 83.08 μM[2].

[1]

HepG2 and SK-Hep1 cells are maintained in Dulbecco’s modified Eagle’s medium containing 10% heat-inactivated fetal bovine serum, 100 units/mL Penicillin, and 10 μg/mL Streptomycin, at 37°C and 5% CO2. Cell-Counting Kit (CCK)-8is used to analyze the effect of compounds (e.g., Ginsenoside Rg6; 0.01, 0.1, 1 and 10 μM) on cell toxicity. Cells are cultured overnight in 96-well plate (~1×104 cells/well). Cell toxicity is assessed after the addition of compounds on dose-dependent manner. After 24 h of treatment, 10 μL of the CCK-8 solution is added to triplicate wells, and incubated for 1 h. Absorbance is measured at 450 nm to determine viable cell numbers in wells[1].
