Bufalin is an active ingredient and one of the glycosides in the traditional Chinese medicine ChanSu; it is also a bufadienolide toxin originally isolated from the venom of the Chinese toad Bufo gargarizans, with potential cardiotonic and antineoplastic activity. Although the mechanism of action of bufalin is still under investigation, this agent is a specific Na+/K+-ATPase inhibitor and can induce apoptosis in cancer cell lines through the activation of the transcription factor AP-1 via a mitogen activated protein kinase (MAPK) pathway.

Bufalin (0, 1, 2, 4 μM for 48 hours) decreases cell viability in NCI-H460 cells.
Bufalin (2 μM) increases caspae-3, Endo G and GADD153 mRNA expression, but decreases the GRP78 mRNA expression.

Bufalin (0.1, 0.2, or 0.4 mg/kg, i.p., daily for 14 days) shows significant anti-tumor activity in mice bearing NCI-H460 cells.
