Technical Data

Formula

C19H17N3O2S2
Molecular Weight 383.49 CAS No. 1346546-69-7
Solubility (25°C)* In vitro DMSO 76 mg/mL (198.17 mM)
Water Insoluble
Ethanol Insoluble
In vivo (Add solvents to the product individually and in order)
Clear solution
5%DMSO 40%PEG300 5%Tween80 50%ddH2O
2.5mg/ml Taking the 1 mL working solution as an example, add 50 μL of 50 mg/ml clarified DMSO stock solution to 400 μL of PEG300, mix evenly to clarify it; add 50 μL of Tween80 to the above system, mix evenly to clarify; then continue to add 500 μL of 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 GSK'872 is a potent and selective RIP3 kinase inhibitor which binds RIP3 kinase domain with high affinity (IC50=1.8 nM) and inhibits kinase activity with IC50 of 1.3 nM. It has minimal cross-reactivity.
Targets
RIP3K [1]
(Cell-free assay)
1.3 nM
In vitro When assayed at 1 μM, GSK'872 fails to inhibit most of 300 human protein kinases tested. It fails to inhibit RIP1 kinase when tested directly. GSK'872 blocks TNF-induced necroptosis in a concentration-dependent manner in HT-29 cells. In cell-based assays, there is a 100- to 1000-fold shift in the IC50 compared to the cell-free biochemical assays. GSK'872 also blocks necroptosis in primary human neutrophils isolated from whole blood. GSK'872 inhibits TLR3- or DAI-induced death, two RIP1-independent pathways of necroptosis. It induces caspase activation followed by apoptotic cell death[1].
In vivo GSK'872 treatment significantly decreases HIF-1α expression compared with no treatment after ischemia injury in vivo[3].
