TCPOBOP is the most potent known member of the phenobarbital-like class of cytochrome P450 (CYP)-inducing agents. TCPOBOP, short for 1,4-Bis[2-(3,5-dichloropyridyloxy)]benzene, is a synthetic chemical compound that is used as a selective agonist of the constitutive androstane receptor (CAR). It is employed in laboratory research studies to investigate the role and function of CAR in various biological processes. TCPOBOP induces activity of ER1 cytochrome P450 isozymes, NADPH-cytochrome c reductase, microsomal epoxide hydrolase and glutathione S transferase. TCPOBOP acts as a tumor promoter of murine hepatocarcinogenesis and activates orphan nuclear receptors mCAR (mouse Constitutive Androstane Receptor) and hPXR(human Pregnane X Receptor), but has little or no activity on hCAR and mPXR. Additionally, TCPOBOP also suppresses the multidrug resistance gene expression in mouse liver cells.
