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), an antihelminthic and antifungal agent, is associated with a host of adverse effects including nephrotoxicity, hepatotoxicity, and teratogenicity. Bioactivation of the primary metabolite of TBZ, 5-hydroxythiabendazole, has been proposed to yield a reactive intermediate. Here we show that

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

Separate high performance liquid chromatographic methods were developed for thiabendazole (TBZ) and 5-hydroxy thiabendazole (5-OH-TBZ) determination in horse plasma using 1-methyl-2-phenyl benzimidazole (MPBZ) as an internal standard. In both methods TBZ and 5-OH-TBZ were extracted from plasma using organic solvents

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).
