实验参考方法
In Vitro

In vitro activity: In vitro study showed that, in both mouse and human CD4+ T cells, the treatment with STA-21 could induce the expression of FoxP3 and repressed IL-17 expression. In addition, STA-21 was able to prevent both human monocytes and mouse BMM cells from differentiating into osteoclasts.


Cell Assay: Human breast cancer cell lines MDA-MB-231, MDA-MB-435s, MDA-MB-453, MDA-MB-468, and MCF7, human ovarian carcinoma cell line Caov-3, and human skin fibroblasts were cultured in DMEM containing 10% FBS and appropriate antibiotics in a 5% CO2 incubator at 37°C. For testing different compounds, the cells were exposed to the compounds for 48 h at a final concentration of 20 or 30 μM, respectively. Then, the cells were harvested and subjected to flow-cytometry analysis.

In VivoIn previous animal study, IL-1Ra-KO mice were treated with i.p. injections of STA-21 at 0.5 mg/kg 3 times per week for 3 weeks. Results showed that STA-21 could suppress inflammatory arthritis in IL-1Ra-KO mice. The Th17 cell proportion decreased and the proportion of Treg cells expressing FoxP3 was increased in the spleens of STA-21-treated mice markedly. Moreover, the adoptive transfer of CD4+CD25+ T cells from STA-21-treated IL-1Ra-KO mice suppressed inflammatory arthritis markedly.
