Descriptions:
Ginsenosides, which are active compounds found in ginseng (Panax ginseng), are used as antidiabetic treatments; ginsenoside Rb2 may inhibit palmitate-induced gluconeogenesis via AMPK-induced SHP by relieving ER stress, a cause of gluconeogenesis.[1]
Ginsenoside Rb2 is a inducer of the SOD1 gene, the SOD1 gene is greatly activated by ginsenoside Rb2 through transcription factor AP2 binding sites and its induction.[2]
The intra-tumoral or oral administration of ginsenoside-Rb2 causes a marked inhibition of both neovascularization and tumor growth,the inhibition of tumor-associated angiogenesis by ginsenoside-Rb2 may partly contribute to the inhibition of lung tumor metastasis.[3]
Ginsenoside-Rb2 has hypoglycemic activity in streptozotocin-diabetic rat, one of the mechanisms probably is the changes of glucokinase and glucose-6-phosphatase levels.
Ginsenoside-Rb2 has anti-oxidant activity, has hydroxyl radical scavenging activity changes by heat processing.[4]
Ginsenoside Rb2 can enhance the expression of the sterol regulated element binding protein (SREBP) mRNA whereas treatment with cholesterol and FBS led to a reduction in the abundance of this transcript, suggests that it might be a valuable component capable of lowering the levels of lipids.[5]
Ginsenoside-Rb2 is the most effective among ginsenosides from red ginseng to prevent the lethal infection of HVJ, so that this ginsenoside is a promising candidate as a mucosal immunoadjuvant to enhance antiviral activity.[6]
