Description

Arenobufagin, a representative natural bufadienolide compound, is the major active component extracted from toad venom. Arenobufagin is a part of Chinese medicine Chan'su. It possesses significant antineoplastic activity in vitro. Antineoplastic activity of arenobufagin was tested using cell lines from different cancers: breast cancer, hepatocellular carcinoma, prostatic cancer, etc. Arenobufagin acts by intercalating with DNA and disrupting the cell cycle. Also it was shown to inhibit PI3K/Akt/mTOR pathway (in hepatocellular carcinoma cells) and inhibit Na, K-ATPase.

In Vitro Use Guide
Human hepatocellular carcinoma cell lines (HepG2 and HepG2/ADM) were treated with arenobufagin (10(-6)-10(-9) M). The growth of both cell lines was inhibited in a dose- and time-dependent manner with IC50 values of 20.24 nM and 7.46 nM after 72 h treatment, respectively.
