FICZ

Research use only, not for human use.

FICZ is a high affinity aryl hydrocarbon receptor (AhR) agonist with Kd of 70 pM.

FICZ is a high affinity aryl hydrocarbon receptor (AhR) agonist with Kd of 70 pM; induces transient expression of CYP1A1 in vitro, and potentiates NK cell IFN-γ production and cytolytic activity; enhances NK cell control of tumors in an NK cell- and AhR-dependent manner in vivo; an endogenous AhR ligand.

FICZ (0.01 nM-1 μM) alone or in combination with 50 nM MNF induces sustained CYP1A1 activity and leads to oxidative stress and activation of apoptosis via a mitochondrial-dependent pathway. In HepG2 cells, FICZ stimulates cell growth at low concentrations but inhibits cell growth at high concentrations. FICZ (10,000-30,000 nM) significantly decreases CEH viability with an estimated LC50 (95% confidence intervals) of 14,000 nM. FICZ shows concentration-dependent effects on EROD activity in CEH cultures, with the mean EC50 values at 3, 8, and 24 h of 0.016 nM, 0.80 nM, and 11 nM, respectively. FICZ treatment increases transcript expression of CYP1A1 in a dose-dependent manner in both the parental iPSC line and the CYP1A1 targeted clone. CYP1 inhibition in the presence of FICZ results in enhanced AHR activation, suggesting that FICZ accumulates in the cell when its metabolism is blocked. CYP1 enzymes plays a role in regulating biological effects of FICZ.Nuclear export and degradation of the AHR protein are two additional steps in the AHR-mediated signal transduction pathway.Exposure to AhR agonists causes AhR-expressing cells to downregulate the receptor through the ubiquitin/proteasome degradation pathway.
