4 Pharmacology and Biochemistry
4.1 MeSH Pharmacological Classification

Herbicides

Pesticides used to destroy unwanted vegetation, especially various types of weeds, grasses (POACEAE), and woody plants. Some plants develop HERBICIDE RESISTANCE. (See all compounds classified as Herbicides.)


4.2 Absorption, Distribution and Excretion

Toxicokinetic behavior and recoveries of isoproturon from feces, urine, and different tissues of goat were determined after 4, 5, 6, and 7 days following single oral administration at 500 mg/kg. Isoproturon was rapidly absorbed and attained blood concentration within 15 min of administration. The kinetic behavior followed a two-compartment open model. The higher half-life (beta) (9.78 +/- 0.33 hr) and V(d)()area (4.49 +/- 0.41 L/kg) associated with lower Cl(B) (0.32 +/- 0.02 L/kg/hr) suggested slow elimination from the blood. Approximately 56% of the total administered compound was recovered from feces. The rate of excretion of isoproturon through feces was maximum at 48 hr and could not be detected beyond 120 hr. The excretion pattern of isoproturon through urine resembled that of feces, and approximately 10-11% was eliminated in urine. A maximum quantity of residue was detected in all tissues of goats slaughtered after 4 days followed by a substantial decline after day 5, and nothing could be detected after day 7. Histopathological study revealed that isoproturon produced moderate cellular changes like fatty degeneration in the liver and kidney and emphysema in the lung after 7 days post administration.

4.3 Metabolism/Metabolites

Using ring-(14)C-labeled isoproturon (1 ug/L), the uptake into spawn and tadpoles of Bombina bombina and Bombina variegata was investigated. Two percent of the applied radioactivity was found per gram fresh weight in the embryo after 24 hr. Results indicate that the jelly mass of the spawn does not act as a sufficient physical barrier for protection against the uptake and influence of isoproturon (IPU) on the embryo. In vivo metabolism of ring-(14)C-labeled IPU by the cytochrome P-450 system was analyzed in tadpoles. Different metabolites of IPU, such as N-demethylated and C-hydroxylated derivatives, and the olefinic metabolite were detected. In tadpoles of B. variegata, the activity of microsomal and soluble glutathione-S-transferase (sGSTs) toward different model substrates was measured after treatment with IPU. Activities of sGST increased corresponding to elevated stress by IPU dependent on exposure time and dose. Compared to the pure active ingredient IPU, the commercial phenyl-urea herbicide Tolkan Flo, consisting of IPU and an emulsifier, also caused significantly elevated enzymatic response.
