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.)
They are efficiently absorbed from intestine, and presumably there is some absorption across the skin and lung. /Urea-, uracil- and triazine-based herbicides/

Absorbed through both foliage and roots. It appears to penetrate foliage rapidly, minimizing removal from foliage by rain. /It is/ translocated acropetally through xylem from roots and foliage, accumulating in apical meristems.

Terbutryn ... was metabolized by both rats and goats after a single oral dose by one or more of the following pathways: S-demethylation, conversion of thiomethyl into hydroxyl, N-de-ethylation, oxidation of the terminal carbon of the ethyl group to a carboxylic acid, oxidation of a terminal carbon of the t-butyl group to an alcohol or a carboxylic acid, or conjugation with glucuronic acid.

Carbon-labeled terbutryn was admin as single oral doses to rats and goats. Urine was collected at intervals up to 72 hr and then analyzed ... after isolation of glucuronides by chromatographic procedures. Five conjugates isolated and identified were: 2-amino-4-(t-butylamino)-6-(S-glucuronyl)-s-triazine; 2-(t-butylamino)-4-ethylamino-6-(S-glucuronyl)-s-triazine; 2-ethyl-amino-(2-methyl)glucuronylpropyl)amino-6-(S-methylthio)-s-triazine; 2-amino-4-(2-(1-glucuronyl-2-methylpropyl)amino)-6-methylthio-s-triazine; 2-ethylamino-4-(2-(2-methyl propan-1-olyl)amino)-6-(S-glucuronyl)-s-triazine.

After administration of terbutryne to rats, urinary metabolites observed ... included: 2-hydroxy terbutryne; 2-amino-4-hydroxy-6-t-butylamino-s-triazine; 2-amino-4-t-butylamino-6-mercapto-s-triazine; two S-glucuronides and two t-butyl-O-glucuronides. Other metabolites were formed by one or a combination of the following reactions: N-alkyl oxidation to alcohols or acids: S-demethylation; N-deethylation; and disulfide formation.

Microsomes prepared from livers from 30 to 70 year old patients undergoing liver resection were incubated with 6.3 to 1,000 uM atrazine, terbuthylazine, terbutryne, or ametryne , and the incubation mixtures were analyzed for metabolites. The compounds produced a variety of metabolites indicative of S-oxidation, N-dealkylation, and side chain C-oxidation. The metabolites were formed by processes showing biphasic kinetics, Michaelis constants for the first and second phases varying from 1.4 to 20 uM and from 54 to 530 uM, respectively. Atrazine, terbuthylazine, ametryne, or terbutryne at 25 uM was incubated with human liver microsomes containing substrates for cytochrome-P4501A2 (CYP1A2), cytochrome-P4502A6, cytochrome-P4502D6, cytochrome-P4502C9, cytochrome-P4502C19, cytochrome-P4502E1, or cytochrome-P4503A4 (CYP3A4) isozymes. Other microsomal preparations were incubated with 25 or 600 uM of the S-triazines in the presence or absence of alpha-naphthoflavone (aNF), furafylline, quinidine, sulfaphenazole, diethyl-dithiocarbamate, gestodene, or ketoconazole, inhibitors of various specific cytochrome-P450 (P450) isozymes, at concentrations 5 to 10 times greater than their inhibition constants. Microsomal preparations containing substrates for CYP1A2 and CYP3A4 showed the best correlation with the rates of metabolism of the S-triazines. Only aNF and furafylline, inhibitors of CYP1A2, inhibited metabolism of the S-triazines. A human liver microsomal preparation with demonstrated high levels of flavin containing monooxygenase (FMO) activity and purified recombinant human FMO-3 were incubated with ametryne and terbutryne. The extent of sulfoxidation of the two compounds was determined. No significant formation of sulfoxide metabolites was detected, indicating that the FMO system was not involved in the metabolism of S- triazines by human liver microsomes. The authors conclude that these results clearly identify CYP1A2 as the major phase-I P450 isozyme that is involved in the metabolism of S-triazines by human liver microsomes.

... Their chief mode of action appears to involve carbohydrate metabolism. The chlorinated s-triazines inhibit starch accumulation by blocking the prodn of sugars. Similar behavior has been shown for the methoxy & methylthio-s-triazines. It has been reported that the s-triazines affect the tricarboxylic acid cycle with activation of phospho-phenyl pyruvate-carboxylase causing the disappearance of sucrose & glyceric acid with the formation of aspartic & malic acids. /S-triazines/

The influence of some s-triazine herbicides on acid phosphatase and phosphodiesterase from corn (Zea mays) roots were investigated. Terbutryn stimulated both phosphatases, whereas prometryn stimulated only the phosphodiesterase. Atrazine desmetryn, prometon, and simazine inhibited acid phosphatase. No effect was exerted by ametryn. The enzyme assays and the kinetic parameters demonstrated that the interferences observed were due to an action on the synthesis of one or both enzymes rather than on the enzyme reactions. The types of the N-alkyl and the chlorine-subsitutuent groups in the structures of the s-triazines tested appear important in determing the degree of the interference.
