General description

Chemical structure: imidazole

Application

Thiabendazole (TBZ) is a broad-spectrum antihelminthic and is used to treat parasitic infections in humans. It is used as an agricultural fungicide and as a food preservative. Thiabendazole has been used as a heavy metal chelating detoxification agent. It is used clinically to treat threadworm, cutaneous larva migrans, visceral larva migrans, and trichinosis.

Biochem/physiol Actions

Thiabendazole inhibits anaerobic respiration at the level of mitochondrial helminth-specific enzyme. It acts as a quinol-fumarate reductase (QFR) inhibitor in ,C. jejuni and H. pylori, blocking quinol oxidation to quinone. Thiabendazole suppresses egg and larval production and may inhibit the subsequent development of eggs and larvae which are passed in feces. A proposed route of biotransformation of thiabendazole is the CYP1A2-catalyzed hydroxylation to 5-hydroxythiabendazole, which is metabolized to glucuronide and sulfate conjugates.

Thiabendazole (TBZ) and its major metabolite 5-hydroxythiabendazole (5OH-TBZ) were screened for potential time-dependent inhibition (TDI) against CYP1A2. Screen assays were carried out in the absence and presence of NADPH. TDI was observed with both compounds, with k(inact) and K(I) values
