Biological Activity

[Description]:

Actein is a triterpene glycoside isolated from the rhizomes of Cimicifuga foetida. Actein suppresses cell proliferation, induces autophagy and apoptosis through promoting ROS/JNK activation, and blunting AKT pathway in human bladder cancer. Actein has little toxicity in vivo[1][2].
