Epyrifenacil
Based on 1 Customer Validation
Epyrifenacil is a protoporphyrinogen oxidase (PPO) inhibiting herbicide, potently targeting the PPO2 isoform from weeds such as Amaranthus palmeri with an IC50 of 0.637 nM. Epyrifenacil also inhibits liver mitochondrial PPO across species, with IC50 values of 2.2 nM (mouse), 2.6 nM (rat), 12.1 nM (rabbit), 7.6 nM (dog), and 10.2 nM (human). Epyrifenacil induces liver tumor development in mice. Epyrifenacil can be used for weed control, and also used as a tool compound in toxicological research to study the mechanism of PPO inhibition, chemical-induced hepatotoxicity, and the mode of action of non-genotoxic carcinogens in rodents[3].

Biological Activity
Epyrifenacil (156-5000 μg/plate) shows no genotoxic potential in the bacterial reverse mutation test[2].
Epyrifenacil (1.9-120.0 μg/mL) shows no genotoxic potential in the mammalian cell gene mutation test[2].
Epyrifenacil (15.6-125 μg/mL) shows no genotoxic potential in the mammalian chromosomal aberration test[2].
Epyrifenacil (40 ppm) exhibits systemic herbicidal activity in three-leaf stage wild soybean plants, completely killing whole plants including shoot apical meristems within 5 days of foliar application at 40 ppm[3].
Epyrifenacil (20 g a.i. ha-1) provides complete control of barnyardgrass and Italian ryegrass in glasshouse pot trials when applied as a late-post foliar spray at 20 g a.i. ha-1[3].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
Epyrifenacil (50, 300, and 800 ppm; dietary; ad libitum daily; 90 days) induces dose-dependent hepatotoxicity and anemia in Crl:CD(SD) rats, with NOAELs of 3 mg/kg bw/day for males and 19 mg/kg bw/day for females[1].
Epyrifenacil (100, 300, and 1000 mg/kg; p.o.; daily; 90 days) induces dose-dependent anemia and liver glycogen elevation in TOYO beagles, with NOAELs of 100 mg/kg bw/day for males and 300 mg/kg bw/day for females, and no evident hepatocyte injury[1].
