Abstract
Two phenylpropanoids from BUPLEURUM FRUTICOSUM (Apiaceae/Umbelliferae) were shown to inhibit the transcriptional activity induced by PMA or TNFα of an NF-κB-controlled reporter gene. Western blot experiments indicated that the phenylpropanoids did not prevent IκBα degradation, suggesting that their molecular target is at a post-IKB degradation level. Both compounds prevented cytokine (IL-1, IL-6, TNF, IL-8) release and prostaglandin E
