Kaurenoic acid (original) (raw)

Kaurenoic acid (ent-kaur-16-en-19-oic acid or Kauren-19-oic acid) is a diterpene with antibacterial activity against Gram-positive bacteria. However its low solubility and blood lytic activity on erythrocytes might make it a poor pharmaceutical candidate. Kaurenoic acid also has uterine relaxant activity via calcium blockade and opening ATP-sensitive potassium channels. Kaurenoic acid is found in several plants such as Copaifera. It is a potential biomarker for the presence of sunflower in foods.
