HPLC Analysis of Diuron and Metabolites in Blood and Urine

Abstract: A high-pressure liquid chromatographic method for the determination of diuron and its metabolites in human urine and blood is presented. The synthesis of different metabolites and of a suitable internal standard is described and the structure of the compounds is determined by mass spectrometry and nuclear magnetic resonance spectroscopy. The method is applied to an overdose case.

“…Although morphologic alterations were intermittently observed, significant delays in hatching time were noted for compound II at 8.6 and 17 µM and at all tested concentrations of compound VI (Figure 3). Embryo/larval assays were then conducted with either compound II or its Ndemethylation product (compound III), the primary metabolite of II in humans (28). At the 8.6 µM exposures, hatch delays for larvae exposed to compound II but not to compound III were significant ( Figure 4); however, < 3% of the embryos failed to hatch within 14 days.…”

“…With the fathead minnow sEH, compound III was a 14-fold more potent inhibitor than compound II, while the other tested orthologs showed only a 2.2 ± 0.9-fold enhancement. Because N-dealkylation is a dominant metabolic transformation and degradation route of many alkylureas (28)(29)(30), this finding suggests that medaka may provide a better model for mouse and human sEH inhibition than fathead minnow.…”

“…On préfère cependant la méthode HPLC-MS pour doser le diuron comme proposé par Van Boven et coll., en 1990 [36]. L'échantillon biologique (urine ou sang) acidifié à pH 2 est extrait par le dichlorométhane.…”

“…In mammals, it is biotransformated by dealkylation of methylureic groups of carbons two and/or six from the benzene ring via cytochrome (CYP) P450s enzymes, generating 3,4-dichlorophenyl and 3,4-dichloroaniline (3,4-DCA) [2][3][4][5][6]. Thus, a possible adverse effect could be operative for humans exposed to larger amounts of Diuron and that present a high CYP1A 1 and 2 contents, which may be able to metabolize Diuron more efficiently [7].…”
