Kamebakaurin, a compound of kaurane diterpenes was isolated from traditional Chinese medicinal plant Isodon excia. It is a potent inhibitor of NF-kappaB activation by directly targeting DNA-binding activity of p50[6].
Treated with different concentrations of kamebakaurin (0-30µM;24 h), The activity of HCT116 cells did not decrease significantly, but Kamebakaurin inhibits HIF-1α protein expression in cells [1]. Kamebakaurin (0.1, 1.0, 5 µM) significantly inhibited the LPS-induced production of nitric oxide (NO) in a concentration-dependent fashion in activated microglial cells[2]. Kamebakaurin (0-500ng/ml;4h)dose-dependently attenuated iNOS gene expression in LPS-activated dendritic cells (DCs). Kamebakaurin significantly inhibited the gene expression and protein production of the inflammatory cytokines TNF-α, IL-12, and IL-1β[4].
Kamebakaurin (50 mg/kg;40 days;p.o.) produced significant growth inhibition of HCT116 cells in tumor xenograft model[1]. Kamebakaurin dose-dependently suppressed the inflammation in an adjuvant arthritis model. Oral administration of 20 mg/kg kamebakaurin resulted in the 75% decrease of paw volume[3]. Pretreatment with Kamebakaurin reduced the magnitude of Acetaminophen (N-acetyl-p-aminophenol, APAP)-induced increases in plasma levels of hepatic injury markers, lipid peroxidation, and inflammatory response[5].
