IQ-1S free acid is a prospective inhibitor of NF-κB/activating protein 1 (AP-1) activity with an IC₅₀ of 2.3±0.41 μM. IQ-1S free acid has binding affinity (K_d values) in the nanomolar range for all three JNKs with K_ds of 100 nM, 240 nM, and 360 nM for JNK3, JNK1, and JNK2, respectively.

Compound IQ-1S is a potent, noncytotoxic inhibitor of pro-inflammatory cytokine [interleukin (IL)-1α, IL-1β, IL-6, IL-10, tumor necrosis factor (TNF)-α, interferon-γ, and granulocyte-macrophage colony-stimulating factor] and nitric oxide production by human and murine monocyte/macrophages. The effect of IQ-1S is evaluated on LPS-induced cytokine production in human PBMCs. Among the 12 cytokines analyzed, LPS (200 ng/mL) consistently induces five (IL-1α, IL-1β, IL-6, IL-10, and TNF-α) in PBMCs compared with DMSO-treated control cells. Production of all of these cytokines is significantly inhibited by 20 μM IQ-1S. Among them, TNF-α production is inhibited completely by IQ-1 (>99%), the levels of IL-1α, IL-1β, and IL-10 are decreased by 85%, and IL-6 production is decreased by 33%^[1].

Human PBMCs are plated in 96-well plates at a density of 2×10⁵ cells/well in culture medium supplemented with 3% (v/v) endotoxin-free FBS. PBMCs are pretreated with 20 μM IQ-1S or DMSO for 30 min, followed by addition of 200 ng/ml LPS for 24 h. A human cytokine MultiAnalyte ELISArray Kit is used to evaluate various cytokines (IL-1α, IL-1β, IL-2, IL-4, IL-6, IL-8, IL-10, IL-12, IL-17A, interferon (IFN)-γ, TNF-α, and granulocyte-macrophage colony-stimulating factor in supernatants of PBMCs^[1].

Mice^[1]
For in vivo analysis, 12.5 or 30 mg/kg i.p. doses of IQ-1S (The sodium salt of IQ-1) are administered to BALB/c mice (15-20 animals/group), and the mice are sacrificed at various time points after compound administration. For quantification, a calibration curve is established using mouse serum samples spiked with known concentrations of IQ-1S (0.1-20 μM), and a linear dependence of the peak area with IQ-1S concentration is obtained (correlation coefficient r=0.997). The area under the serum concentration-time curve (AUC_0-12h) is calculated using the linear trapezoidal method up to the last measured concentration^[1].
