1. Cytotoxic activity. Has strong non-specific cytotoxic activity against P388 and a group of human cancer cell lines in vitro.
2. Immune regulatory effect. Significantly inhibit the formation of hemolytic plaque cells in mouse spleen cells. Significantly inhibit delayed hypersensitivity reactions in mice.
3. Anti inflammatory effect. At a dose of 0.5mg/kg, it significantly inhibited the formation of cotton ball granulomas in rats. Inhibition of PGE2 production induced by yeast sugar at 0.1-1.0 μ g/mL; At a concentration of 1.0 μ g/mL, it inhibits the phagocytic activity of macrophages.
4. The anti peroxidation effect of Triptolide is 15 times that of tocopherol, with an IC50 of 7 μ M. Inhibit peroxidation inside and outside the mitochondrial membrane, directly clearing free radicals.
