GinseNOSide Rg5 是红参的主要成分，可阻断IGF-1与其受体的结合，IC50约为90 nM。它还通过抑制NF-Κb p65的 DNA 结合活性来抑制COX-2的 mRNA 表达。它可促进血管生成和改善高血压，具有抗炎和治疗阿尔茨海默病的潜力。

1. Ginsenoside Rg5 could be a beneficial agent for the treatment of Alzheimer's disease. 2. Ginsenoside Rg5 suppresses LPS-induced nitric oxide (NO) production and proinflammatory TNF-α secretion. 3. Ginsenoside Rg5 can ameliorate lung inflammation possibly by inhibiting the binding of LPS to toll-like receptor (TLR)-4 on macrophages. 4. Ginsenoside Rg5 plays a novel role as an IGF-1R agonist, promoting therapeutic angiogenesis and improving hypertension without adverse effects in the vasculature. 5. Ginsenoside Rg5 blocks cell cycle of SK-HEP-1 cells at the Gl/S transition phase by down-regulating cyclin E-dependent kinase activity and that the down-regulation of cyclin E-dependent kinase activity is caused mainly by induced CDK2 inhibitor, p21Cip/WAF1 and decreased levels of cyclin E.
