Ordering Information

Biological Activity

GSK872 is a potent and selective receptor-interacting protein kinase 3 (RIP3/RIPK3) inhibitor that binds directly to the RIP3 kinase domain. By inhibiting kinase phosphorylation within the RIPK1/RIPK3/MLKL signaling pathway, GSK872 effectively blocks necroptotic cell death. Consequently, it suppresses downstream necroptosis-associated phenotypes and RIP3-mediated inflammatory signaling responses, including interleukin-1β (IL-1β) maturation and cytokine secretion in immune cells.

FAQ
Q: Why does a DMSO stock precipitate in media/saline?
A: It is caused by unheated aqueous media (supersaturation), local solvent shock, or incorrect mixing sequence.
How to fix it?
  • Preheat media/saline to 37°C.
  • Mix rapidly (pipette/vortex) upon addition.
  • For complex mixes, always add the aqueous phase last.
  • Re-dissolve minor precipitates with a 37°C water bath and sonication (≤30 min).
