生物活性

Ginsenoside Rk1 is a unique component created by processing the ginseng plant (mainly Sung Ginseng, SG) at high temperatures. Ginsenoside Rk1 has anti-inflammatory effect, suppresses the activation of Jak2/Stat3 signaling pathway and NF-κB. Ginsenoside Rk1 has anti-tumor effect, antiplatelet aggregation activities, anti-insulin resistance, nephroprotective effect, antimicrobial effect, cognitive function enhancement, lipid accumulation reduction and prevents osteoporosis. Ginsenoside Rk1 induces cell apoptosis by triggering intracellular reactive oxygen species (ROS) generation and blocking PI3K/Akt pathway.

Ginsenoside Rk1 (0-40 μM; 6 hours) inhibits MCP-1 and TNF-α mRNA induced by lipopolysaccharide (LPS), expression of IL-1β is inhibited at 40 μM.
Ginsenoside Rk1 (0-40 μM; 24 hours) inhibits phosphorylation of JAK2 and STAT3 (Tyr705 and Ser727) in LPS-induced RAW264.7 cells in a dose-dependent manner.
Ginsenoside Rk1 (0-160 μM; 48 hours) results in cell viability significant decrease 75.52 ± 2.51% (40 μM), 52.72 ± 2.54% (80 μM), 17.41 ± 2.94% (120 μM)and 12.63 ± 3.24% (160 μM) compared with control.
Ginsenoside Rk1 (0-120 μM; 24 hours) increases G0/G1 phase proportion accompanied with S and G2/M phase proportion decrease in MDA-MB-231 cells.
Ginsenoside Rk1 (0-120 μM; 24 hours) promotes the percentage of apoptotic cells in a dose-dependent manner, exhibits to reduction of cell number with nucleus fragmentation, condensation and apoptotic body formation.
