Emamectin Benzoate (MK-244) 是一

Emamectin Benzoate (MK-244) is an orally active nervoussystem toxicant by binding g-aminobutyric (GABA) receptor in insects. Emamectin Benzoate is one of semi-synthetic derivative of Avermectin (HY-15311) with a broadspectrum of insecticidal and acaricidal activity. Emamectin Benzoate induces ROS-mediated DNA damage and cell apoptosis. Emamectin Benzoate, a mixture of the natural Emamectin B1a benzoate and Emamectin B1b benzoate, has the main component of Emamectin B1a benzoate^[1][2].

GABA Receptor

Emamectin Benzoate (MK-244; 2.5-40 μM; 12 and 24 h) decreases cell viability in a time- and dose-dependent manner^[1].
Emamectin Benzoate (2.5-20 μM; 24 hours) induces apoptosis and DNA damage in 16HBE cells. Emamectin Benzoate induces ROS generation in 16HBE cells^[1].
Emamectin Benzoate (2.5-20 μM; 12 hours) increases the amounts of cytochrome-c, caspase-3, cas-pase-9, cleaved-PARP, Bax/Bcl-2^[1].
Emamectin Benzoate (2.5, 5, 10, 15 μM; 72 h) inhibits cell viability with an IC₅₀ of 3.72 μM in Trichoplusia Tn5B1-4 cell. Emamectin Benzoat induces chromatin condensation in nuclei and cell apoptosis^[2].

Cell Viability Assay^[1]

Emamectin Benzoate (MK-244; oral; 25-100 mg/kg/day; for 14 days) causes a marked induction of oxidative damage in liver tissue^[3].
