Epimedokoreanin B

Epimedokoreanin B is a natural flavonoid with anticancer, anti-inflammatory and antibacterial effects. Epimedokoreanin B inhibits the growth of lung cancer cells through endoplasmic reticulum stress-mediated apoptosis accompanied by autophagosome accumulation. Epimedokoreanin B is an anti-periodontitis agent that inhibits gingipains and Porphyromonas gingivalis growth and biofilm formation^[1][2][3]. In Vitro:Epimedokoreanin B (compound6; 3.13-25 μM; 48 hours) shows significate inhibitory effect on proliferation against lung cancer cell A549, Calu1 and H1299. Epimedokoreanin B displays no toxic on human bronchial epithelial cells BEAS-2B^[1]. Epimedokoreanin B treatment inhibits cell proliferation and migration accompanied by cytoplasmic vacuolation in A549 and NCI-H292 cells. Atophagosome accumulation accompanied with autophagy flux blocking is observed in Epimedokoreanin B treated cells, this was consistent with the occurrence of ER stress^[2].
Epimedokoreanin B (5 μM; 24 hours) inhibits CD163 expression and IL-10 production, which are known M2 markers, suggesting that Epimedokoreanin B inhibits M2 polarization in human monocyte-derived macrophages (HMDMs). Epimedokoreanin B suppresses STAT3 activation in HMDMs^[4]. In Vivo:Epimedokoreanin B (20 mg/kg; p.o; thrice a week; for 17 days) inhibits tumor growth in an LM8 tumor-bearing murine model^[4].
