Использование
Agricultural chemical.
Опасность
Moderately toxic by ingestion and skin contact. Low toxicity by inhalation.
Фармаколо?гия
Plant Metabolism. The selectivity of imazaquin is due to
differential rates and routes of metabolism in tolerant
crops versus susceptible weeds (3). The primary
metabolite in soybeans is a pyrroloquinoline acetamide
(41, Fig. 18), which is immobile in the plant and is not
an inhibitor of acetolactate synthase. This metabolite is
further broken down to eventually yield a dicarboxylic acid.
Animal Metabolism. Metabolism studies in the rat
showed that they rapidly excreted unchanged imazaquin
in the urine (5). There was no accumulation of imazaquin or any of its derivatives in the liver, kidney, muscle,
fat, or blood. There was no detectable residue in the
liver, kidney, muscle, or fat of lactating goats and
laying hens, which were fed imazaquin for 7 consecutive
days (5).
Метаболизм
Imazaquin kills plants by inhibiting acetolactate synthase
(ALS) (I50 = 1 μM), which is the first common
enzyme in the biosynthesis of the branched chain amino
acids, valine, leucine, and isoleucine. Imazaquin is rapidly
absorbed through the roots of plants. Once it enters
the plant, imazaquin rapidly translocates to the growing
points and growth ceases within 1 day after herbicide
application followed by chlorosis and then necrosis of the
growing points. Total plant death will occur within 2 to
3 weeks after treatment.
