Biological Activity

High affinity NLRP3 inflammasome inhibitor (Kd = 52.5 nM). Forms covalent bind within NACHT domain and blocks interaction of NLRP3 with NEK7 to inhibit assembly and activation of inflammasome. Inhibits glial activation, decreases inflammatory cytokine release, attenuates synaptic loss and improves behavioural deficits in Aβ1-42 treated mice. Also displays anti-cancer properties in various cancer cell lines.

Preparing Stock Solutions

The following data is based on the product molecular weight 364.44. Batch specific molecular weights may vary from batch to batch due to the degree of hydration, which will affect the solvent volumes required to prepare stock solutions.

Select a batch to recalculate based on the batch molecular weight:
Concentration / Solvent Volume / Mass 1 mg 5 mg 10 mg
1 mM 2.74 mL 13.72 mL 27.44 mL
5 mM 0.55 mL 2.74 mL 5.49 mL
10 mM 0.27 mL 1.37 mL 2.74 mL
50 mM 0.05 mL 0.27 mL 0.55 mL
