Ephemeranthol A
Ephemeranthol A is a phenanthrene compound with anticancer and anti-inflammatory activities. Ephemeranthol A exerts significant anti-inflammatory effects in macrophages by inhibiting the NF-κB and MAPK signaling pathways. Ephemeranthol A induces apoptosis and inhibits metastasis of lung cancer cells by suppressing the FAK/Akt signaling and EMT processes. Ephemeranthol A can be used for the research of acute and chronic inflammatory diseases and non-small cell lung cancer.
