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.

GSK872 (1 μM) has no inhibition for most of 300 human protein kinases tested. It fails to inhibit RIP1 kinase. In HT-29 cells, GSK872 concentration-dependently blocks TNF-induced necroptosis. In cell-based assays, there is a 100- to 1000-fold shift in the IC50 compared to the cell-free biochemical assays. GSK872 inhibits DAI- or TLR3-induced (RIP1-independent) death. It induces caspase activation and then induces apoptotic cell death.

In compared with no treatment after ischemic injury in vivo, GSK872 can significantly reduce HIF-1α expression.
