Monoethyl phthalate
Based on 1 Customer Validation
Monoethyl phthalate is an orally active PDX-1 activator and the major hydrolytic metabolite of Diethyl phthalate (HY-Y0284) in vivo, with reproductive toxicity. Monoethyl phthalate targets aromatase (aromatase/CYP19A1) and PPAR to induce cell proliferation. The plasma protein binding rate of Monoethyl phthalate in rats and humans is lower than that of Diethyl phthalate. It exhibits significant enterohepatic circulation in rats and mainly accumulates in liver tissues. Monoethyl phthalate shows no estrogenic activity in estrogen-dependent human breast cancer cells. Monoethyl phthalate can be used in studies of reproductive toxicity and related environmental endocrine disruption mechanisms.

Monoethyl phthalate, a metabolite of diethyl phthalate (DEP) in male Sprague-Dawley rats, is generated following a single intravenous injection of diethyl phthalate (HY-Y0284) at doses of 0.1-10 mg/kg. It exhibits dose-linear pharmacokinetic characteristics within the range of 0.1-10 mg/kg, preferentially distributes to the liver, and is mainly excreted in urine[1].
Diethyl phthalate (DEP) (0.1-10 mg/kg; p.o.; single administration) exhibits dose-linear pharmacokinetic characteristics in rats. The plasma peak concentration of monoethyl phthalate is achieved within 0.75-0.92 h, and monoethyl phthalate is primarily excreted via urine[1].
