In addition, our results suggest CYP1A2 inhibition as the mechanism behind the observed thiabendazole/theophylline and primaquine/antipyrine interactions in vivo.

In particular, several therapeutic drugs including antofloxacin, carbamazepine, dihydralazine, furafylline, isoniazid, rofecoxib, clorgyline, thiabendazole, and zileuton are mechanism-based inhibitors of CYP1A2.

Chem Biol Interact. 2000 Jul 3;127(2):109-24.

Thiabendazole (TBZ), an anthelmintic and fungicide benzimidazole, was recently demonstrated to be extensively metabolized by cytochrome P450 (CYP) 1A2 in man and rabbit, yielding 5-hydroxythiabendazole (5OH-TBZ), the major metabolite furtherly conjugated, and two minor unidentified metabolites (M1 and M2).

In the CYP1A subfamily, CYP1A2 appears to be responsible for basal 5-hydroxylation and further unidentified metabolism of thiabendazole in control livers.

Thus, CYP1A2 is a major isoenzyme involved in thiabendazole 5-hydroxylation.

Treatment of human hepatocytes for 72 h with 2-200 microM TB produced concentration-dependent increases in CYP1A2, CYP2B6 and CYP3A4 mRNA levels, whereas treatment with BHT increased CYP2B6 and CYP3A4 mRNA levels.

TB changed the expression of 12 genes, including CYP1A2.

The effect of sulfur-containing benzimidazoles (thiabendazole, 5-hydroxy-thiabendazole, cambendazole) and sulfur-free derivatives (benzimidazole, carbendazim and 5-hydroxycarbendazim) on cytochrome P450 enzymes was investigated in primary cultures of rabbit hepatocytes considered 72 h after plating.
Experiments using actinomycin D strongly suggest that these compounds have a transcriptional control on both CYP1A1 and CYP1A2 genes in primary hepatocytes.

Drug Metab Dispos. 2006 Aug;34(8):1376-85. Epub 2006 May 19.

We report here that imidazole derivative drugs: the anthelminthics, albendazole and thiabendazole; the proton pump inhibitor, omeprazole; the thromboxane synthase inhibitor, benzylimidazole; and the aromatase (CYP19) inhibitor vorozole (R76713, racemate; and R83842, (+) enantiomer) increased hepatic microsomal EET formation in a chick embryo model.
Albendazole increased EETs by transcriptional induction of CYP1A5 and the others by combined induction of CYP1A5 and CYP2H, the avian orthologs of mammalian CYP1A2 and CYP2B, respectively.

The administration of high doses of TB resulted in the induction of 7-ethoxyresorufin O-deethylase and 7-pentoxyresorufin O-depentylase activities, CYP1A1, CYP1A2, CYP2B1 and CYP2B1/2 mRNA levels and CYP1A2 and CYP2B1/2 apoprotein levels.
