生物活性:
Ossirene (AS101), an immunomodulatory tellurium compound, is a potent IL-1β inhibitor. Ossirene abolishes phosphorylation of STAT3 by inhibiting IL-10. Ossirene potently inhibits Caspase-1 and is used for the autoimmune diseases and certain malignancies.
体内研究:
Ossirene (AS101; 0.5 mg/kg/day; IP; 25 days) sensitizes GBM tumors to paclitaxel via inhibition of IL-10, resulting in increased survival. Animal Model:SCID mice with GBM cells
Dosage:0.5 mg/kg
Administration:IP; daily; 25 days
Result:Significantly increased survival of GBM tumor-bearing mice.
体外研究:
Ossirene (AS101; 1 μg/mL; for 24 hours) almost completely abrogates expression of pStat3. Ossirene may reduce expression of Bcl-2 after inhibition of Stat3 activation via IL-10 inhibition. AS101 (0.5, 5 mg/mL; 24 hours) inhibits IL-1β-induced mRNA expression of inflammatory mediators in the RPE in a dose-dependent manner. AS101 inhibits IL-1β-induced mRNA expression and protein production of IL-6 and IL-8 in RPE cells. AS101 (5 mg/mL; 1 hour) inhibits the phosphorylation of the p65 component of the NFκB complex activated by IL-1β. Ossirene (0.1, 0.5, 1, 2.5 μg/mL) significantly decreases B16 melanoma, stomach adenocarcinoma, and human glioblastoma multiforme (GBM) cells proliferation. AS101 (0.5 μg/mL; for 24 hours) sensitizes GBM tumor cells to paclitaxel in an IL-10-dependent manner.
