Bioactivity | GSK-872 is a RIPK3 inhibitor, which binds RIP3 kinase domain with an IC50 of 1.8 nM, and inhibits kinase activity with an IC50 of 1.3 nM. GSK-872 decreases the RIPK3-mediated necroptosis and subsequent cytoplasmic translocation and expression of HMGB1, as well as ameliorates brain edema and neurological deficits in early brain injury[1][2][3]. | ||||||||||||
Target | IC50: 1.3 nM (RIPK3) | ||||||||||||
Invitro | GSK-872 (GSK'872; 0.01-3 μM; 24 hours) blocks TNF-induced necroptosis in human HT-29 cells in a concentration-dependent manner[1]. Cell Viability Assay[1] Cell Line: | ||||||||||||
In Vivo | GSK-872 (25 mM; intracerebroventricular injection) can attenuate brain edema and improve neurological function following subarachnoid hemorrhage (SAH) and reduce the number of necrotic cells. GSK-872 can also decrease the protein levels of RIPK3 and MLKL, and cytoplasmic translocation and expression of HMGB1, an important pro-inflammatory protein[3]. Animal Model: | ||||||||||||
