TCPOBOP is an agonist of the constitutive androstane receptor (CAR) (EC50 = 20 nM). TCPOBOP enhances the nuclear receptor CAR transactivation of cytochrome P450 (CYP), as dose-dependent direct agonist of CAR. The most potent known member of the phenobarbital-like class of CYP-inducing agents. TCPOBOP has been used for enhancing Mcl-1-Italics promoter functions in mouse hepatoma cells. TCPOBOP has also been used to study constitutive androstane receptor(CAR)-induced gene expression in mouse hepatocytes.
