體外研究
Engeletin is a flavanonol glycoside isolated from hymenaea martiana , inhibits NF-κB signaling-pathway activation.
體內(nèi)研究
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.
