Question

Diference between cardinolides and bufadinolides

Answer 1

Answer:

Cardioactive glycosides are a kind of steroid glycosides, which act on the human heart. We can distinguish two main aglycone types of the cardioactive glycosides: cardenolides and bufadienolides. Medicinally the cardenolide group is more important. Cardenolides have a steroid skeleton with 23 C-atoms and contain γ-lacton (butenolide) ring, e.g. digitoxygenin.

Bufadienolides with 24 C-atoms contain, on the C-17 carbon atom, a δ-lacton ring (α, β - γ, δ doubly unsaturated), e.g. scillarenin
