Biological Activity

FICZ is a potent aryl hydrogen receptor (AhR) agonist. FICZ acts by inducing transient expression of cytochrome P450-1A1 (CYP1A1) in vitro. 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.

For example, to modify the dose of resveratrol used for a mouse (22.4 mg/kg) to a dose based on the BSA for a rat, multiply 22.4 mg/kg by the Km factor for a mouse and then divide by the Km factor for a rat. This calculation results in a rat equivalent dose for resveratrol of 11.2 mg/kg.
