What is GSK840?

Biological Activity

GSK840 is a receptor-interacting protein kinase 3 (RIP3 or RIPK3) inhibitor, binds with high affinity to the RIP3 kinase domain with an IC50 of 0.9 nM, and inhibits kinase activity with an IC50 of 0.3 nM.

in vitro

GSK840 (GSK'840) (0.01-3 μM; 24 hours) blocks TNF-induced necroptosis in a concentration-dependent manner.
GSK840 binds the kinase domain and inhibits kinase activity with high specificity, targeting a broader range of pro-necrotic stimuli than can be achieved with RIP1 kinase inhibitors.
