How to use

In Vitro:

IQ-3 exhibits IC50 of 2.2 μM (TNF-α in human monoMac-6 cells), 1.5 μM (IL-6 in human monoMac-6 cells), 4.7 μM (TNF-α in human PBMCs), 9.1 μM (IL-6 in human PBMCs) and 6.1 μM (NO in murine J774.A1), respectively. IQ-3 exhibits an IC50 of 1.4 μM for inhibiting LPS-induced NF-κB/AP-1 transcriptional activity in human THP-1 Blue monocytic cells. IQ-3 is indeed a competitive inhibitor for the ATP binding site of JNK3.
