Animal experiment: | Mice[1]The mice are classified at random into the following six groups of 10 mice each to cause the endometritis model: blank group, LPS group, Engeletin (25, 50, and 100 mg/kg) + LPS groups, and Engeletin (100 mg/kg) group. Engeletin is solubilized by heated normal saline to give the final concentrations of 25, 50, and 100 mg/kg. Briefly, each uterus is infused with 50 μL of LPS (1 mg/mL) to induce endometritis. At 24 h after the instillation, Engeletin groups receive an intraperitoneal injection of diverse Engeletin concentrations (25, 50, and 100 mg/kg) three times (once every 6 h). The Engeletin group is given an intraperitoneal injection of Engeletin (100 mg/kg). The blank group receive the normal saline. Afterward, the mice are killed by CO2 inhalation. Uterus tissues are harvested and kept in −80°C[1]. |

Engeletin is a flavanonol glycoside isolated from hymenaea martiana, inhibits NF-κB signaling-pathway activation, and possesses anti-inflammatory, analgesic, diuresis, detumescence, and antibiosis effects.
Engeletin is a flavanonol glycoside isolated from hymenaea martiana, inhibits NF-κB signaling-pathway activation[1].
Engeletin (25, 50, 100 mg/kg, i.p.) markedly reduces LPS-increased myeloperoxidase activity in mice, activates NF-κB-pathway activation, decreases the production of inflammatory mediators (iNOS and COX-2), and suppresses the expression of TLR4-signaling downstream molecules such as MyD88, IRAK1, TRAF6, and TAK1 proteins[1].
