Protoanemonin

CAS: 108-28-1

Protoanemonin is a naturally occurring toxin, which is derived from plants in the Ranunculaceae family, such as buttercups. This compound forms when these plants are mechanically damaged, serving as a part of their chemical defense mechanism. Protoanemonin exerts its mode of action through the inhibition of key enzymes like thiol-containing enzymes, which disrupts cellular processes. This leads to cellular apoptosis and can cause severe irritation to biological tissues upon contact.
