Ordering Information

Biological Activity

IKK-16 is a selective IκB kinase inhibitor that targets IKK-2, the IKK complex, and IKK-1. By blocking IKK-mediated phosphorylation, it prevents NF-κB signaling pathway activation and reduces downstream pro-inflammatory gene expression. Additionally, IKK-16 inhibits leucine-rich repeat kinase 2 (LRRK2) kinase activity and Ser935 phosphorylation in cells. Consequently, this compound serves as a valuable tool for investigating NF-κB and LRRK2 signaling mechanisms in inflammatory and neuronal cellular models.

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).
