Description:

WARNING: This product is for research use only, not for human or veterinary use.

GSK-963, also known as GSK'963 or GSK963, is a potent and selective inhibitor of RIP1 kinase. GSK'963 is significantly more potent than Nec-1 in both biochemical and cellular assays, inhibiting RIP1-dependent cell death with an IC50 of between 1 and 4 nM in human and murine cells. GSK'963 is >10 000-fold selective for RIP1 over 339 other kinases, lacks measurable activity against IDO and has an inactive enantiomer, GSK'962, which can be used to confirm on-target effects.

More Info
The increased in vitro potency of GSK'963 also translates in vivo, where GSK'963 provides much greater protection from hypothermia at matched doses to Nec-1, in a model of TNF-induced sterile shock. Together, we believe GSK'963 represents a next-generation tool for examining the function of RIP1 in vitro and in vivo, and should help to clarify our current understanding of the role of RIP1 in contributing to disease pathogenesis.
Product Data
Biological target:
GSK963 is a chiral, highly potent and selective inhibitor of RIP1 kinase, with an IC50 of 29 nM.
In vitro activity:
GSK′963 efficiently blocked necroptosis in both murine and human cells with IC50 values of 1 nM and 4 nM, respectively, whereas the inactive analog GSK′962 was at least 1000-fold less potent in these assays (Figures 2a and b). Reference: Cell Death Discov. 2015 Jul 27;1:15009. https://pubmed.ncbi.nlm.nih.gov/27551444/
In vivo activity:
Treatment of animals with 2 mg/kg of GSK′963 resulted in a complete protection from TNF+zVAD-induced temperature loss, with the 0.2 mg/kg dose also showing a significant response (Figure 3c). As expected, GSK′962 had no effect on the TNF+zVAD-induced shock, confirming that GSK′963 was acting selectively through RIP1 kinase inhibition (Figure 3d).

Note: There can be variations in solubility for the same chemical from different vendors or different batches from the same vendor. The following factors can affect the solubility of the same chemical: solvent used for crystallization, residual solvent content, polymorphism, salt versus free form, degree of hydration, solvent temperature. Please use the solubility data as a reference only. Warming and sonication will facilitate dissolving. Still have questions? Please contact our Technical Support scientists.
