Product Introduction

Bioactivity
Description
Ossirene (AS101), a potent in vitro and in vivo immunomodulator, is a novel inhibitor of IL-1beta converting enzyme.
In vitro
Treatment of caspase-1 (interleukin-1 [IL-1] converting enzyme [ICE]) with Ossirene inhibits its enzymatic activity in a dose-dependent manner. Moreover, Ossirene treatment 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 Ossirene 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[1]. Ossirene 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 Ossirene (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[2].
In vivo
Ossirene 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, Ossirene also exerted beneficial effects[1]. Ossirene treated rats showed a large increase in SIRT1 protein levels in the liver and kidney extracts of rats treated with Ossirene. Ossirene prevents development of insulin resistance in vivo. Ossirene affects SIRT1 related metabolic pathways by changing the insulin levels. Ossirene 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[2].
Cell Research
In vitro, PBMCs were first treated with various concentrations of AS101, and after 1 h SAC (10-3 v/v) was added. After 24 h, supernatants were collected and evaluated for cytokine content. (Only for Reference)

In Vivo Formulation Calculator (Clear solution)

Please enter your animal experiment information in the following box and click Calculate to obtain the mother liquor preparation method and in vivo formula preparation method:
TargetMol | Animal experimentsFor example, your dosage is 10 mg/kg Each animal weighs 20 g, and the dosage volume is 100 μL . TargetMol | Animal experiments A total of 10 animals were administered, and the formula you used is 5% TargetMol | reagent DMSO+30% PEG300+5% Tween 80+60% ddH2O. So your working solution concentration is 2 mg/mL。
Mother liquor preparation method: 2 mg of drug dissolved in 50 μL DMSOTargetMol | reagent (mother liquor concentration of 40 mg/mL), if you need to configure a concentration that exceeds the solubility of the product, please contact us first.
Preparation method for in vivo formula: Take 50 μL DMSOTargetMol | reagent main solution, add 300 μLPEG300TargetMol | reagent mix well and clarify, then add 50 more μL Tween 80, mix well and clarify, then add 600 more μLddH2OTargetMol | reagent mix well and clarify
