Eupalinolide B

• Description :

  Eupalinolide B is a germ sesquiterpene. Eupalinolide B can be isolated from Eupatorium lindleyanum. Eupalinolide B induces Apoptosis, elevates ROS, promotes Autophagy. regulates GSK-3β/β-catenin, targets UBE2D3 and TAK1, activates ROS-ER-JNK, inhibits NF-κB and MAPKs. Eupalinolide B has anticancer activity against pancreatic cancer and liver cancer. Eupalinolide B relieves rheumatoid arthritis, acute lung injury, periodontitis, depression[1][2][3][4][5][6][7].
