PK68 has highly potent inhibition of TNF-induced necroptosis with EC50 values of 23 nM and 13 nM in human and mouse cells, respectively[1].
PK68 is a highly selective inhibitor of RIPK1 kinase activity with IC50 value of 90 nM[1].
PK68 (100 nM, 1 h) blocks necroptosis through the suppression of RIPK3 function or signaling upstream of RIPK3 activation[1].

Select the appropriate dissolution method based on your experimental animal and administration route.
- For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
- To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for In Vivo experiments, it is recommended to prepare freshly and use it on the same day.
- The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.
Add each solvent one by one: 10% DMSO 90% (20% SBE-β-CD in Saline)
Solubility: ≥ 3 mg/mL (7.07 mM); Clear solution
