General description

5-Hydroxythiabendazole present in excreta, eggs, edible tissues and milk is found to be the major metabolite of thiabendazole, an active ingredient in fungicidal preparations effective for plants. It can also be used as an anthelmintic drug, which is applicable both for humans and animals.

Application

Refer to the product′s Certificate of Analysis for more information on a suitable instrument technique. Contact Technical Service for further support.
Thiabendazole and its metabolite 5-hydroxythiabendazole can undergo specific binding with monoclonal antibodies and can further undergo immobilization on agarose gels, which can find applications in immunoaffinity chromatography.

Thiabendazole (TBZ) is a broad-spectrum antihelmintic used for treatment of parasitic infections in animals and humans and as an agricultural fungicide for postharvest treatment of fruits and vegetables. It is teratogenic and nephrotoxic in mice, and cases of hepatotoxicity have

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).

This report characterized one of the major cytochrome P450 isozyme involved in thiabendazole metabolism. This study was undertaken by using both cultured rabbit hepatocytes treated or not with drugs known to specifically induced various cytochromes P450 isoenzymes (i.e., P450 1A1/2

A novel liquid chromatographic multiresidue method has been developed for quantitation of thiabendazole (TBZ), the metabolite 5-hydroxythiabendazole (5-OH-TBZ), and the sulfate conjugate of 5-hydroxythiabendazole (5-HSO4-TBZ) in raw cow's milk. The 5-HSO4-TBZ is hydrolyzed quantitatively under acidic conditions to 5-OH-TBZ. TBZ
