Kaurenoic acid is a diterpene that has been found in C. langsdorffii and has diverse biological activities, including anticancer, antibacterial, antioxidant, and anti-inflammatory properties.1,2,3 It is cytotoxic to 22Rv1 and LNCaP prostate, HT-29, HCT116, SW480, and SW620 colon, and MCF-7 breast cancer cells with IC50 values ranging from 15.03 to 48.87 μg/ml.2 Kaurenoic acid is active against S. epidermidis, S. capitis, E. faecalis, and S. haemolyticus in vitro (MICs = 6.25-12.5 μg/ml).3 Kaurenoic acid (50 and 100 mg/kg) reduces colonic myeloperoxidase (MPO) activity and malondialdehyde (MDA) levels in a rat model of acetic acid-induced colitis, as well as colonic tissue damage, leukocytic infiltration, and submucosal edema when administered at a dose of 100 mg/kg.1 | [Uses]
ent-Kaurenoic Acid can be used in biological study. Kinetic profile of guaco syrup metabolites like coumarin, 7-hydroxycoumarin, o-coumaric acid, kaurenoic acid can be performed for identification of alternative route of coumarin metabolism in human plasma. | [Definition]
ChEBI: An ent-kaurane diterpenoid that is ent-kauran-19-oic acid in which a double bond is present at position 16(17); exhibits anticancer and anti-HIV 1 activity. | [in vivo]
Kaurenoic acid (1-10 mg/kg, i.g., single dose) reduces peritonitis and pain induced by lipopolysaccharides (HY-D1056) in mice[2].
Kaurenoic acid (as a diterpene compound) is the main active ingredient in the root bark extract of A. senegalensis that exhibits anticonvulsant effects in mice[3]. | Animal Model: | Mice induced by LPS[2] | | Dosage: | 1, 3, 10 mg/kg; single dose | | Administration: | i.g. | | Result: | Inhibited LPS-induced mechanical and thermal hyperalgesia, suppressed MPO activity, regulated the redox state of mouse paws, inhibited the production of pro-inflammatory/pain cytokines (such as TNF-α, IL-1β, and IL-33), and enhanced the production of anti-inflammatory/analgesic cytokine IL-10. |
