Bufalin is a cardiotonic steroid toxin^[1] originally isolated from Chinese toad venom, which is a component of some traditional Chinese medicines.^[2]^[3]

Research

Bufalin has in vitro antitumor effects against various malignant cell lines, including hepatocellular^[4] and lung carcinoma.^[5] However, as with other bufadienolides, its potential use is hampered by its cardiotoxicity.^[6]
