anemonin
Sign in to saveAnemonin is a dibutenolide natural product found in members of the buttercup family (Ranunculaceae) such as Helleborus niger, Ranunculus bulbosus, R. ficaria, R. sardous, R. sceleratus, and Clematis hirsutissima. Originally isolated in 1792 by M. Heyer, It is the dimerization product of the toxin protoanemonin. One of the likely active agents in plants used in Chinese medicine as an anti-inflammatory and Native American medicine as a horse stimulant, its unique biological properties give it pharmaceutical potential as an anti-inflammatory agent.

== Biosynthetic origins == Anemonin is a homodimer formed from two protoanemonin subunits. Protoanemonin is formed from the enzymatic cleavage of ranunculin upon crushing plant matter. When a plant from this family is injured, a β-glucosidase cleaves ranunculin, liberating protoanemonin from glucose as a defense mechanism. This butenolide readily dimerizes in aqueous media to form a single cyclodimer.
