体外研究 (In Vitro) |
Ginsenoside Rk3 exerts the strong activity inhibiting NF-κB in a dose-dependent manner. HepG2 cells are pre-treated with different ginsenosides at concentrations ranging from 0.01 to 10 μM for 1 h, and induced with TNF-α for 20 h. Ginsenoside Rk3 significantly inhibits TNF-α-induced NF-κB transcriptional activity, with an IC50 of 14.24±1.30 μM. Ginsenoside Rk3 significantly inhibits TNF-α-induced NF-κB transcriptional activity, with an IC50 of 15.32±0.29 μM in SK-Hep1 cells, consistent with the data from HepG2 cells. Consistent with the inhibition of NF-κB, Ginsenoside Rk3 inhibits the induction of IL8, CXCL1, iNOS, and ICAM1 mRNA significantly in a dose-dependent manner[1].

体内研究 (In Vivo) |
The inhibitory effects of Ginsenoside Rk3 (Rk3) on tumor progression are studied in vivo using a H460 xenograft model in nude mice. Compared with the control group, a significant inhibition of tumor growth (volume) is observed in the Ginsenoside Rk3-treated group. Twenty-one days after treatment initiation, tumor growth is significantly inhibited by approximately 62.99% in the mice receiving 20 mg/kg Ginsenoside Rk3, similar to the inhibitory effect observed in the 20 mg/kg Gefitinib-treated group (57.21%). Compared with the control group, tumor growth is moderately inhibited in the mice receiving 10 and 5 mg/kg Ginsenoside Rk3, with inhibition rates of 32.54% and 11.84%, respectively[2].

Cell Assay [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)-8 is used to analyze the effect of compounds (e.g., Ginsenoside Rk3; 0.01, 0.1, 1 and 10 uM) 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].
