Background

Ammonium tri-chloro(dioxoethylene-O,O′-)tellurate (AS-101), an anti–IL-10 compound, is a nontoxic immunomodulator.

AS101 (0.5-2.5 μg/ml) decreased IL-10 production in a dose-dependent manner. Incubation of RMCL and RMC in the presence of AS101 gradually and significantly decreased mesangial cell proliferation [1]. AS101 (0.5 μg/ml, 1 μg/ml) decreased tyrosine phosphorylation and nuclear translocation of stat3 via inhibition of IL-10 [2]. AS-101 induced proliferation and IL-2 production by human lymphocytes and enhanced the production of IL-2 and colony-stimulating factor by mouse spleen cells. Systemically administration of AS-101 to mice mediated antitumour effects. AS-101 directly enhanced the ratio of OKT4 to OKT8-positive cells in cultured mononuclear cells from AIDS patients [3]. AS101 showed significant bone marrow (BM)-sparing effects and preventd hair loss in chemotherapy-treated patients, with minimal overall toxicity [4]. In mice subjected to cecal ligation and puncture (CLP), treatment with AS101 significantly increased survival of septic mice. AS101 treatment restored the ability of these cells to secrete TNF-α and IL-1β. AS101 increased class II Ag expression on peritoneal macrophages. AS101 increased the level of IFN-γ secreted by splenocytes [5].
