铵三氯[1,2-乙二醇-O,O']-碲酸盐

铵三氯[1,2-乙二醇-O,O']-碲酸盐用途

Ossirene (AS101) 是一种免疫调节性碲化合物,有效的 IL-1β 抑制剂。Ossirene 通过抑制 IL-10 消除 STAT3 的磷酸化。Ossirene 有效抑制 Caspase-1,可用于自身免疫性疾病和某些恶性肿瘤。

[体外研究]

骨化(AS101；1μg/mL；24小时)几乎完全抑制pStat3的表达。通过IL-10抑制Stat3激活后,骨化可能降低Bcl-2的表达[2]。AS101(0.5,5mg/mL；24小时)以剂量依赖性方式抑制IL-1β诱导的RPE炎症介质mRNA表达。AS101抑制IL-1β诱导的RPE细胞IL-6和IL-8的mRNA表达和蛋白生成。AS101(5mg/mL；1h)抑制IL-1β激活的NF-κB复合物p65组分的磷酸化[1]。骨化(0.1,0.5,1,2.5μg/mL)可显著抑制B16黑色素瘤、胃腺癌和人多形性胶质母细胞瘤(GBM)细胞增殖[2]。AS101(0.5μg/mL；24小时)以IL-10依赖的方式使GBM肿瘤细胞对紫杉醇敏感[2]。Western Blot分析[2]细胞株：B16黑色素瘤细胞浓度：1μg/mL孵育时间：24小时结果：pStat3表达几乎完全消失。RT-PCR[1]细胞株：ARPE19细胞浓度：0.5,5mg/mL孵育时间：24小时结果：抑制IL-1β诱导的RPE炎症介质mRNA表达,呈剂量依赖性。

[体内研究]

骨化(AS101；0.5 mg/kg/天；IP；25天)通过抑制IL-10使GBM肿瘤对紫杉醇敏感,从而提高生存率[2]。动物模型：具有GBM细胞的SCID小鼠[2]剂量：0.5mg/kg给药：IP；每日；25天结果：GBM荷瘤小鼠生存率显著提高。
