0.200mg/ml
(0.64mM)
Taking the 1 mL working solution as an example, add 50 μL 4 mg/ml clarified DMSO stock solution to 400 μL PEG300, mix evenly to clarify it; add 50 μL Tween80 to the above system, mix evenly to clarify it; then continue to add 500 μL ddH2O to adjust the volume to 1 mL. The mixed solution should be used immediately for optimal results.
* <1 mg/ml means slightly soluble or insoluble. * Please note that Selleck tests the solubility of all compounds in-house, and the actual solubility may differ slightly from published values. This is normal and is due to slight batch-to-batch variations. * Room temperature shipping (Stability testing shows this product can be shipped without any cooling measures.)

Biological Activity
Description
A potent in vitro and in vivo immunomodulator, Ossirene (AS101) is a novel inhibitor of IL-1beta converting enzyme.
Targets
IL-1β converting enzyme
In vitro
Treatment of caspase-1 (interleukin-1 [IL-1] converting enzyme [ICE]) with Ossirene (AS101) inhibits its enzymatic activity in a dose-dependent manner. Moreover, it causes a significant reduction in the active form of IL-18 and IL-1 in peripheral blood mononuclear cells (PBMC) and in human HaCat keratinocytes. The inhibitory effect of this compound does not involve nitric oxide (NO) or interferon- (IFN- ), two possible regulators of IL-18 production, and does not occur at the mRNA level. It may exert effects through a posttranscriptional mechanism. AS101 induced SIRT1 expression in a dose dependent manner in three different cell lines, HEK293, HL-60 and Rin-5f. Incubation of HEK293 and HL-60 cell lines with it (0.1-2.5μg/ml) resulted in a dose dependent reduction in PPARγ protein expression relative to the control cells, and the reduction of PPARγ expression is in parallel to increased SIRT1 expression.
In Vivo
Ossirene (AS101) downregulates IL-18 and IL-1 serum levels in a mouse model of lipopolysaccharide (LPS)-induced sepsis, resulting in increased survival. It has also been shown to be protective against lethal and sublethal effects of irradiation and chemotherapy. In a model of cecal ligation and puncture (CLP)-induced sepsis in mice, this compound also exerted beneficial effects. Treated rats showed a large increase in SIRT1 protein levels in the liver and kidney extracts. It prevents development of insulin resistance in vivo and affects SIRT1 related metabolic pathways by changing the insulin levels. AS101 treatment prevents hyperglycemia associated with T2D(type 2 diabetes) and some of the symptoms of the disease in the HFD(high fat diet)+STZ(Streptozotocin) rat model.
PBMCs were first treated with various concentrations of Ossirene (AS101). After 1 h, SAC (10-3 v/v) was added to this compound. After 24 h, supernatants were collected and evaluated for cytokine content.
