Bufadienolide is a chemical compound with steroid structure. Its derivatives are collectively known as bufadienolides, including many in the form of bufadienolide glycosides (bufadienolides that contain structural groups derived from sugars). These are a type of cardiac glycoside, the other being the cardenolide glycosides. Both bufadienolides and their glycosides are toxic; specifically, they can cause an atrioventricular block, bradycardia (slow heartbeat), ventricular tachycardia (a type of rapid heartbeat), and possibly lethal cardiac arrest.[1]
Etymology
The term derives from the toad genus Bufo that contains bufadienolide glycosides, the suffix -adien- that refers to the two double bonds in the lactone ring, and the ending -olide that denotes the lactone structure. Consequently, related structures with only one double bond are called bufenolides, and the saturated equivalent is bufanolide.[2]
Classification
According to MeSH, bufadienolides and bufanolides are classified as follows:[3][4]
- Polycyclic compounds
- Steroids
- Cardanolides
- Cardiac glycosides
- Bufanolides (includes bufenolides, bufadienolides, bufatrienolides)
- Cardenolides
- Cardiac glycosides
- Cardanolides
- Steroids
