In addition to CH3S- displacement by -OH, in rats and rabbits treated with prometryne CH3S-group is dealkylated without sulfur oxidation followed by oxidative coupling to disulfide.
... Hydroxypropazine & hydroxyatrazine were detected when cotton, soybeans, peanuts, & carrots were treated with (14)C-ring-labeled prometryn ... Supporting evidence for methylthio group cleavage came from studies with (14)CH3-labeled prometryn in peas where moderate amount of (14)carbon dioxide were liberated.
Rats & rabbits fed prometryne excreted 2-mercapto-4-amino-6-isopropylamino-s-triazine & bis(2-amino-4-isopropylamino-s-triazinyl-6-yl)disulfide. Mono- & di-dealkylated prometryne analogs were also observed. 8 day old pea plants were exposed ... & harvested 8 days later. Several metab pathways were indicated. In one, the side chain of prometryn was metab and 2-hydroxy-4-amino-6-isopropylamino-s-triazine was identified. In the other, the methylthio group was oxidized to sulfone which readily hydrolyzes to hydroxy analog. Chromatography indicated presence of sulfoxide & hydroxy analogs.
Prometryn in rats and rabbits is converted to both the thio ... /deriv/, & the corresponding disulfide, together with a number of other urinary metabolites.
Prometryn was first registered in the United States in 1964 as a herbicide for the control of weeds in cotton, celery, pigeon peas, and dill. A Registration Standard was issued in March 1987 (NTIS# PB87-184826) ... In studies using laboratory animals, prometryn technical has been shown to be slightly to practically non-toxic for oral, dermal, inhalation and has been placed in Tox Category III (next to lowest in the four categories) for these. Additionally, pertaining to acute eye and dermal irritation, prometryn technical is considered to be slight to practically non toxic, respectively and has been categorized as being in Categories III and IV for these. Prometryn is not considered a sentizer. In a subchronic 28-day feeding study using rats showed that macroscopic and microscopic pathological findings appeared in the high dose animals and were limited to the G.I. tract along with clinical signs and marked decreases in body weights were also seen in these animals. In a 21- day dermal toxicity study with rabbits, no local or systemic toxicity was observed at the highest dose levels (1000 mg/kg/day). In three chronic toxicity/carcinogenicity studies with mice, rats and dogs showed that prometryn was not oncogenic. Prometryn was classified as a Group E Carcinogen (no evidence of human carcinogenic potential) because prometryn did not alter the spontaneous tumor profile for the strains of mice and rats tested. The dog study, however, was not considered because, even though there were some effects, under the conditions of the study, the effects were not oncogenic. A developmental toxicity study with rats showed the highest dose level caused maternal and developmental toxicity. In another study also conducted with rabbits resulted in effects at the highest dose level, including increased abortions and decrease in body weight parameters. A 2-generation reproductive study with rats showed effects at the highest dose level including decrease in body weight and corresponding food consumption. Nevertheless, the statistically significant decrease in pup body weight (also at the high dose level) was considered to be toxicologically significant because of its potential negative impact on postnatally developing systems such as the neuro- and immune systems. In four mutagenicity studies (ames samonella test, chromosomal aberration, bacterial DNA repair, and unscheduled DNA synthesis test) prometryn was found to be negative. A series of (radiolabeled) general metabolism studies with rats showed the greatest distribution of prometryn first in the blood followed by the spleen and then in the lungs. People may be exposed to residues of prometryn through the diet. Tolerances or maximum residue limits have been established for a variety of crop and animal commodities...

吸收、分配和排泄
在大鼠中,大部分施用的敌草隆在48小时内通过尿液和粪便排出。
In the rat, most of the administered prometryn is excreted within 48 hours in urine and feces.
When given by oral gavage to rats as a (14)C-labeled material, 2,4-bis(isopropylamino)-6-methylthio-s-triazine was detected in both urine and feces. The chemical was absorbed and rapidly excreted. Limited transfer to the milk of lactating goats or to the eggs of laying hens was reported. The triazines, including prometryne, are generally well-absorbed by the mammalian gut and probably across the skin. The breakdown of prometryne is not adequately understood ... No detectable residues of prometryne or its metabolites were found in the muscle, fat, blood, liver, kidney, or other organs of sheep and cattle fed up to 100 ppm for 4 weeks. However, prometryne or its breakdown products were found in whole milk samples taken from cows that were fed up to 100 ppm in their diets for 21 days.
