Cinobufotalin is a cardioactive steroid of the bufadienolide class that acts as a specific Na+/K+ ATPase inhibitor. Its inhibitory effects has been experimentally determined to be less active than ouabain. Cinobufotalin has also been observed to contain a significant inhibitory effect on hepatitis B virus (HBV) replication. Found to be a component in Chan Su derived from dried toad venom.
