Description

IQ-3 is a specific inhibitor of the c-Jun N-terminal kinase (JNK) family, with preference for JNK3. IQ-3 exhibits Kd values of 0.24 μM, 0.29 μM and 0.066 μM for JNK1, JNK2 and JNK3, respectively[1].

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[1].
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[1].
IQ-3 is indeed a competitive inhibitor for the ATP binding site of JNK3[1].

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
