Where are bufadienolides found?

What is the difference between Cardenolides and Bufadienolides?

is that cardenolide is (organic chemistry) any of many steroid lactones present in plants as glycosides; they are all toxic, affecting the heart while bufadienolide is (steroid|poison) any of a class of toxic steroids present in some plants and secreted by some toads through the skin as a defense; sometimes present as …

What is Cardinolide and bufadienolide?

Cardenolides are 23-carbon steroids with an α,β-unsaturated five-membered lactone ring on carbon 17. Bufadienolides are 24-carbon steroids with a double unsaturated six-membered lactone ring on carbon 17. Examples include convallamarin, scillaren, and hellebrin.

Are cardiac glycosides steroids?

Cardiac glycosides are steroids having the ability to exert specific powerful action on the cardiac muscle. A very small amount can exert a beneficial simulation on diseased heart. These compounds are primarily valuable in the treatment of congestive heart failure.
