14987951 Lemaire G, Delescluse C, Pralavorio M, Ledirac N, Lesca P, Rahmani R: The role of protein tyrosine kinases in CYP1A1 induction by omeprazole and thiabendazole in rat hepatocytes. Life Sci. 2004 Mar 19;74(18):2265-78.

Benzimidazoles compounds like omeprazole (OME) and thiabendazole (TBZ) mediate CYP1A1 induction differently from classical aryl hydrocarbon receptor (AhR) ligands, 3-methylcholanthrene (3-MC) and 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD).

Benzimidazole compounds, such as omeprazole and thiabendazole, are a different type of CYP1A1-inducer from Ah receptor-ligands, such as 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD) and 3-methylcholanthrene.

Benzimidazole compounds, such as omeprazole and thiabendazole, are a different type of CYP1A1 inducer from Ah receptor-ligands, such as TCDD (2,3,7,8-tetrachlorodibenzo-p-dioxin) and 3-methylcholanthrene.

In particular, several therapeutic drugs including antofloxacin, carbamazepine, dihydralazine, furafylline, isoniazid, rofecoxib, clorgyline, thiabendazole, and zileuton are mechanism-based inhibitors of CYP1A2.
Similar to CYP1A1 and 1B1, CYP1A2 is primarily regulated by the aromatic hydrocarbon receptor (AhR), a ligand-activated transcription factor and a basic helix-loop-helix protein belonging to the Per-Arnt-Sim family of transcription factors.

Omeprazole, thiabendazole, carbendazim, 2-mercaptobenzimidazole and 2-mercapto-5-methoxybenzimidazole caused a dose-dependent increase in CYP1A1 protein levels that reached maximum effect at 250 microm, as measured by Western blot.
Thus, these data indicate that the benzimidazoles utilize the aryl hydrocarbon receptor-arnt-XRE-mediated signal-transduction pathway for induction of the CYP1A1 gene.

The CALUX (chemical activated luciferase expression) assay was developed for the detection of polyhalogenated compounds, based on their affinity for the aryl hydrocarbon (Ah) receptor.
The benzimidazole compounds oxfendazole, fenbendazole, febantel, thiabendazole, mebendazole, omeprazole, lanzoprazole and benomyl were shown to give a positive response in the assay.

Arch Biochem Biophys. 1996 Oct 15;334(2):235-40.


Three benzimidazole compounds, omeprazole (OP), thiabendazole (TBZ), and lansoprazole (LP), were compared with respect to the induction of CYP1A1-mRNA in human hepatoma cells, HepG2.
